`Unit Cooler Mounting
Most evaporators can be mounted with rod hangers, lag screws, or
bolts. Use 5/16" bolt and washers or rod for up to 250 pounds, 3/8" for
up to 600 pounds and 5/8" for over 600 pounds. Care should be taken
to mount the units level so that condensate drains properly. Note that
some unit cooler designs achieve drain pan slope by using different
height mounting brackets. In this situation, the top of the mounting
brackets should be level. Adequate support must be provided to hold
the weight of the unit.
When using rod hangers, allow adequate space between the top of
Figure 4. Large Coolers and Freezers Placement.

the unit and the ceiling for cleaning. To comply with NSF Standard 7,
the area above the unit cooler must be sealed or exposed in such a way
to facilitate hand cleaning without the use of tools. When lagging or
bolting the unit flush to the ceiling, seal the joint between the top and
theceiling with an NSF listed sealant and ends ofopen hanger channels
must be sealed to prevent accumulation of foreign matter.
When locating unit coolers in a cooler or freezer, refer to Figures 1
through 4 for guidelines.
NOTE: Always avoid placement of Unit Coolers
directly above doors and door openings.

Defrost
Manytypes of control arrangements can be used. In some applications,
it may not be necessaryto have scheduled defrost periods. The normal
Toff cycle "ofthe compressor may be adequate to keep the evaporator
coil clear offrost. In other applications, a defrost timer may be necessary
to help assure a clear coil. In a medium temperature environment,"air
defrost" is initiated by the timer, but the evaporator fans continue to
operate to facilitate the melting of frost on the fin surface. Other types
of defrost schemes require that the fans on the evaporator shut off

during the defrost period.
For most applications, two to four defrost cycles per day should be
adequate. The defrost requirements will vary on each installation so
the defrost settings should be determined by observing the system
operation.
-1
Defrost Thermostat
Adjustable (F25 -209 Series)
The defrost duration is determined by the setting of the defrost
termination thermostat. Initially, the thermostat should be set at mid -
range.This will terminate the defrost at about a 60 °F bulb temperature
which will be satisfactory for most applications. A somewhat longer or
shorterdefrostcan be obtained byadjusting the control clockwisefor a
shorter defrostand counterclockwisefora Iongerdefrost.Thefan delay
temperature setting of the thermostat is factory set at 25 °F. It can be
adjusted upward by turning the adjusting screw next to the duration
adjustment with a small screwdriver. Each complete clockwise rotation
ofthis screw raises the setting approximately 3°F.This screw should not
be adjusted more than four turns. Making this adjustment also raises
the defrost termination temperature setting of the thermostat by a
similar amount. For example, with the duration setting at mid - range,
the termination temperature would be approximately 60 °F. Turning
the adjusting screw one turn would raise the fan delay temperature to
about28°F as well as changing theterminationtemperaturefrom 60 °F to
63 °F.On medium temperature applications it may be necessaryto raise
the setting to assure that the thermostat will reset after a defrost.
Adjustable (060 - 100 -00 Series)
This control has an adjustable defrost termination setpoint and an
adjustable differential for controlling the fan delay. Atypical termination
setting is 60 °F with a 25 °F differential. Termination setting may be
adjusted to increase /decrease the length of defrost. The differential
should be adjusted to turn on the fans at 30 to 35 °F (Fan Temperature
= TerminationTemperature — Differential). Actual coil temperature will
be 5 to 10 °F below this value. Some unit coolers are preset and labeled
at the factory with special settings.
Note: Defrost controls are positioned as determined
by engineering test. Job conditions may require
the sensing device to be relocated for optimal
defrosting.
Bimetal Disc
A bimetal disctype thermostat is wired tothe control circuittoterminate
thedefrostcyclewhen thecoiltemperature reachesapproximately55 °F.
The bimetal disc thermostat provides a fan delay to allow moisture on
the coil to freeze after defrost termination.
Note:
On systems where the suction temperature is
above approximately 25 °F, the fans may not
start for an extended period of time.
On freezer applications, it may be necessary to apply a jumper to the
fan delay on a warm box. This can be corrected by jumping the fan
switch contacts. This will allow the fans to start immediately after
defrost termination. This will disable the fan delay.
If moisture blow -off is encountered without the fan delay, a higher
temperature defrost thermostat can be ordered. This thermostat
terminates defrost at 60 °F and prevents the fans from running when
the coil temperature is above 40 °F. Refer to the replacement parts list
for the correct number to order.

Distributor Nozzles
Nozzles supplied with unit coolers are selected for numerous
refrigerants at cataloged operating conditions and 95 °F liquid entering
the expansion valve. If mechanical or another method of subcooling
is used, the nozzle and expansion valve selection should be checked.
For conditions outside those cataloged, use the charts to select a
proper nozzle. Nozzle capacity should be within 135% to 180% of
unit operating condition for optimum coil performance. Nozzles are
available from Sporlan Wholesalers or from Heatcraft Refrigeration
Products. A small nozzle can be drilled larger using the I.D. column in
table 3, page 8. The hole must be accurately centered in the nozzle. A
lathe is preferred for accurate drilling.
Expansion Valves and Distributor Nozzles
Before installing the expansion valve on the distributor of the
evaporator, the proper distributor nozzle must be installed. Two
nozzles are normally shipped with each evaporator for different
refrigerants. Select the nozzle for the refrigerant that will be used.
The size of the nozzles shipped with each evaporator is based on
ordinary conditions, usually 95 °F liquid temperature and a maximum
of 15 °F evaporator TD *. If a mechanical subcooler is to be used in
your system, consult the factory or a representative for distributor
nozzle sizing. This is very important as the nominal capacity of the
nozzle increases as the liquid refrigerant temperature is lowered.
If the correct size nozzle is not installed, poor refrigerant distribution
*Temperature Difference
(design room temperature minus saturated suction temperature)
Selecting Distributor Nozzle at the Job Site
You must know 4 things:
1. Refrigerant
2. Evaporating Temperature
3. Tons or BTUH
4. Highest Liquid Temperature
EXAMPLE: Select a nozzle for R22, 20 °F suction; 67,000
BTUH, 100 °F liquid entering TXV.
67,000
12,000
= 5.58 Tons
From Table 3 on page 8 select Size 4 rated at 3.84 tons. We prefer
selecting at 135 % - 180 %of nominal rating.This istypicallytwo sizes
smaller than the closest tonnage in Table 3.
5.58

= 145% of Nominal Rating - okay.
may occur and poor evaporator operation may be experienced.
For peak performance, it is important to select an expansion valve with
the correct capacity and selective charge. Thermostatic expansion
valves may be mounted in any position, but they should be installed
as close to the evaporator as possible. For best performance, the outlet
of the expansion valve should be installed directly to the distributor
body. If this is not possible, the distance between the valve outlet and
distributor should not exceed 24 inches. Elbows located between the
expansion valve and distributor will hinder proper distribution and
therefore, are not recommended. Some accessories may, however,
necessitate the use of elbows.
Locate the expansion valve bulb on a horizontal length of suction
line as close to the suction header as possible. The bulb should be
clamped tightly on the suction line and insulated with a waterproof
type of insulation. The bulb should never be placed on a coupling or
other obstruction so asto not make 100 %contact with the suction line.
The bulb should never be placed in a trap or downstream of a trap in
a suction line. Locating the bulb on the bottom of a suction line is not
recommended. The bulb should be installed at the 3, 4 or 8, 9 o'clock
position on the suction line. See Figure 5 on page 6.
EXAMPLE: Select a nozzle for R404A, -20 °F suction; 9,400
BTUH, 60 °F liquid entering TXV.

Condensate Drain Lines
Either copper or steel drain lines should be used and properly protected
from freezing. In running drain lines, provide a minimum 1/4 inch per
foot pitch for proper drainage. Drain lines should be at least as large as
the evaporator drain connection. All plumbing connections should be
made in accordance with local plumbing codes. All condensate drain
lines must be trapped, and run to an open drain. They must never be
connected directly to the sewer system.Traps in the drain line must be
located in a warm ambient. We recommend a trap on each evaporator
drain line priortoanyteeconnections.Traps located outside,orextensive
outside runs of drain line must be wrapped with a drain line heater.
The heater should be connected so that it operates continuously. It
is recommended that the drain line be insulated to prevent heat loss.
A heat input of 20 watts per linear foot of drain line for 0 °F ( -18 °C)
room applications and 30 watts per linear foot for -20 °F ( -29 °C) rooms
is satisfactory. In freezers, the evaporator drain pan fitting should be
included when heating and insulating the drain line.
Inspect drain pan periodically to insure free drainage of condensate.
If drain pan contains standing water, check for proper installation.The
drain pan should be cleaned regularly with warm soapy water.
WARNING: All power must be disconnected before clean-
ing. Drain pan also serves as cover of hazardous
moving parts. Operation of unit without drain
pan constitutes a hazard.
Traps on low temperature units must be outside of refrigerated
enclosures. Traps subject to freezing temperatures must be wrapped
with heat tape and insulated.
NOTE: Always trap single evaporator system drain
lines individually to prevent humidity migration.

Space and Location Requirements for
Air Cooled Condensing Units and Remote Condensers
The most important consideration which must be taken into account
when deciding upon the location of air - cooled equipment is the
provision for a supply of ambient air to the condenser, and removal of
heated air from the condensing unit or remote condenser area. Where
this essential requirement is not adhered to, it will result in higher
head pressures, which cause poor operation and potential failure of
equipment. Units must not be located in the vicinity of steam, hot air
or fume exhausts. Corrosive atmospheres require custom designed
condensers.
Another consideration which must be taken is that the unit should be
mounted away from noise sensitive spaces and must have adequate
support to avoid vibration and noise transmission into the building.
Units should be mounted over corridors, utility areas, rest rooms and
other auxiliary areas where high levels of sound are not an important
factor. Sound and structural consultants should be retained for
recommendations.
Figure 8. Space and Location Requirements for Condensing Units and Remote Condensers
Walls or Obstructions
The unit should be located so that air may circulate freely and not
be recirculated. For proper air flow and access all sides of the unit
should be a minimum of "W "away from any wall or obstruction. It
is preferred thatthis distance be increased whenever possible. Care
should betakentoseethatample room is left for maintenance work
through access doors and panels. Overhead obstructions are not
permitted. When the unit is in an area where it is enclosed by three
walls the unit must be installed as indicated for units in a pit.
AIR FLOW
Multiple Units
For units placed side by side, the minimum distance between
units is the width of the largest unit. If units are placed end
to end, the minimum distance between units is 4 feet.

Units in Pits
The top of the unit should be level with the top of the pit, and
side distance increased to "2W".
If the top of the unit is not level with the top of pit, discharge
cones or stacks must be used to raise discharge air to the top of
the pit. This is a minimum requirement.

Condensing Units
General Installation
The indoor compressor units are designed to be used with a remote
condenser. The water cooled units are similar, except that they have
an integral water cooled condenser. Inlet and outlet water connections
are to be made in the field. On units having a compressor water jacket,
incoming water shall be routed through the jacket prior to entering
the condenser. For cleaning purposes, condenser end plates can be
removed to give access to the water tubes. Cleaning is accomplished
by a simple spiral tool powered by an ordinary electric drill. During
installation, allow space for cleaning the condenser. Commercial
equipment of this type is intended for installation by qualified
refrigeration mechanics.
Typical Arrangements
Diagram 1 illustrates a typical piping arrangement involving a remote
condenser located at a higher elevation, as commonly encountered
when the condenser is on a roof and the compressor and receiver are
on grade level or in a basement equipment room.
In this case, the design of the discharge line is very critical. If properly
sized for full load condition, the gas velocity might be too low at
reduced loads to carry oil up through the discharge line and condenser
coil. Reducing the discharge line size would increase the gas velocity
sufficiently at reduced load conditions; however, when operating at
full load, the line would be greatly undersized, and thereby creating an
excessive refrigerant pressure drop. This condition can be overcome
in one of two of the following ways:
1. The discharge line may be properly sized for the desired pressure
drop at full load conditions and an oil separator installed at the bottom
of the trap in the discharge line from the compressor.
2. A double riser discharge line may be used as shown in Diagram 2.
Line "A "should be sized to carry the oil at minimum load conditions and
the line "B "should be sized so that at the full load conditions both lines
would have sufficient flow velocity to carry the oil to the condenser.
Water Regulating Valve
Using this control on the water cooled condensing units, the head
pressure can be maintained by adjusting the flow of water through
the condenser section. This type control is most often located on the
water entering side of the condenser and is regulated by the refrigerant
condensing pressure.
Subcooler
Diagrams 1 and 2 below show typical subcooler piping. Diagram 1
is the preferred connection with receiver as it provides maximum
subcooling. Diagram 2 may be used if the receiver is located far from
the condenser.
Diagram 1
Diagram 2
Notes:
1. All oil traps are to be as short in radius as possible.
Common practice is to fabricate the trap using three
90 degree ells.
2. Pressure relief valves are recommended at the condenser
for protection of the coil.
3. A pressure valve at the high point in the discharge line is
recommended to aid in removing non - condensables.
4. The placement of a subcooler should be that it does not
interfere with normal airflow of the condenser. Increased
static of the unit could cause a decrease in system capacity
and fan motor damage.
GPM Requirements
The GPM Requirements table below can be used as a guide for
determining water flow requirements of the condenser. Operation
below the minimum flow rates may result in excessive fouling and
poor heat transfer. Operation above the maximum flow rates risk
premature impingement corrosion and tube failure.

' Condensing Unit Rigging and Mounting
Rigging holes are provided on all units. Caution should be exercised
when moving these units. To prevent damage to the unit housing
during rigging, cables or chains used must be held apart by spacer
bars. The mounting platform or base should be level and located so
as to permit free access of supply air.
Ground Mounting
Concrete slab raised six inches above ground level provides a suitable
base. Raising the base above ground level provides some protection
from ground water and wind blown matter. Beforetightening mounting
bolts, recheck level of unit.The unit should in all cases be located with
a clear space in all directions that is at a minimum, equal to the height
ofthe unit above the mounting surface. Acondensing unit mounted in
a corner formed by two walls, may result in discharge air recirculation
with resulting loss of capacity.
Roof Mounting
Due to the weight of the units, a structural analysis by a qualified
engineer may be required before mounting. Roof mounted units should
be installed level on steel channels or an I -beam frame capable of
supporting the weight ofthe unit. Vibration absorbing pads or springs
should be installed between the condensing unit legs or frame and
the roof mounting assembly.

Condensing Unit Accessories
Suction.Filters, Driers, Sight Glasses
There are two types of suction and liquid filter /driers used on
Heatcraft Refrigeration Products units. Replaceable core and /or
sealed units are used, dependent upon the option package ordered.
Suction filters, regardless of type, are always installed upstream of
the compressor suction service valve, and any accumulators or other
options that may be installed. Suction filters are equipped with
"Schrader "type access valves to allow field measurement of pressure
drop across the device. This allows plugged filters and elements to
be identified very quickly and easily so they can be replaced when
the pressure drop is excessive. Refer to the specific manufacturers'
recommendation on servicing these units by make and model.
Liquid filter /driers, regardless of type, are always installed downstream
of the receiver outlet service valve, and upstream of the liquid line
solenoid valve (if supplied). Liquid line driers may or may not have an
access valve, dependent on the size and application.
The basic servicing of these units is similar to suction filters. Liquid
line driers should be replaced whenever there is evidence of excessive
pressure drop across the filter, or the system becomes contaminated
due to system leaks, compressor burnouts, acid formation, or
moisture accumulation as indicated by the liquid line sight glass.
The sight glass is installed in the main liquid line assembly, downstream
from the receiver outlet service valve, and immediately after the liquid
line drier. The sight glass is designed to give a visual indication of
system moisture content with refrigerantflowing . Slight color indication
on a new system is common and will be eliminated during system
evacuation. Generally, it requires no field service. However, in cases of
extreme acid formation in a system after a compressor burnout, the
acid may damage the sensing element or etch the glass. This would
require that the sight glass be replaced, along with the liquid line drier
after any compressor motor burnout.

CAUTION: Fans closest to the headers should not be
cycled on standard temperature or pressure

changes at the headers as a result of fan
action can result in possible tube failure.
Fan motors are designed for continuous
duty operation.
Fan cycling controls should be adjusted to maintain a mini-
mum of (5) minutes on and (5) minutes off. Short cycling of
fans may result in a premature failure of
motor and /or fan blade.
Compressors operating below +10 °F SST must have air
flowing over the compressor at all times when the compres-
sor is running.

Operating Range
Demand Cooling is designed to protect the compressor from high
discharge temperatures over the evaporating and condensing
temperature ranges shown in Figure 12 at a maximum return gas
temperature of 65 °F.

Copeland Demand Cooling for Discus L2 Models
F -22, when used in a properly designed and controlled refrigeration
system, is a realistic low temperature refrigerant alternative to R -502,
which was phased out due to its high ozone depletion potential.
However, experience has shown R -22 can present problems as a low
temperature . refrigerant because under some conditions the internal
compressor discha rge temperature exceeds the safe temperature limit
for long term stability of refrigeration oil. Forthis reason suction to liquid
heat exchangers are not recommended unless they are necessary to
prevent another potential problem.
The Copeland Demand Cooling System
Copeland'sdemand cooling system uses modern electronicstoprovidea
reliable, cost - effective solution to this problem. It is required for all single
stage R-22applicationswith saturated suction temperatures below -10 °F.
The Demand Cooling module uses the signal of a discharge head
temperature sensor to monitor discharge gas temperature. If a critical
temperature is reached,the module energizes a long life injection valve
which meters a controlled amount of saturated refrigerant into the
compressor suction cavity to cool the suction gas. Refer to Figure 13.
This process controls the discharge temperature to a safe level. If, for
some reason,the dischargetemperature rises above a preset maximum
Ievel,the DemandCooling modulewillturnthecompressoroff (requiring
a manual reset) and actuate its alarm contact.To minimize the amount
of refrigerant which must be injected, the suction gas cooling process
is performed after the gas has passed around and through the motor.

gas temperature line shows

-30 -20 -10
Evaporating Temperature ( °F)
0
When Demand Cooling operates, it "diverts" refrigeration capacity
in the form of injected saturated refrigerant from the evaporator to
the compressor. The effect of this diversion on evaporator capacity is
minimal because the diverted capacity is used to cool the gas entering
the compressor. As the gas is cooled, it naturally becomes more
dense, increasing the mass flow through the compressor, which partly
compensates for the capacity diverted from the evaporator.
1. Compressor Return Gas Temperature: Suction lines
should be well insulated to reduce suction line heat gain.
Return gas superheat should be as low as possible
consistent with safe compressor operation. Minimum 20 °F
superheat at the compressor is required.
2. Condensing Temperatures: It is important when using
R -22 as a low temperature refrigerant that condensing
temperatures be minimized to reduce compression ratios
and compressor discharge temperature.
3. Suction Pressure: Evaporator design and system control
settings should provide the maximum suction pressure
consistent with the application in order to have as low a
compression ratio as possible.
In most cases, with floating head systems where condensing
temperatures are low during most of the year, Demand Cooling will
operate primarily as a compressor protection control much as the
oil failure control protects the compressor during periods of low oil
pressure. Demand Cooling will be allowed tooperateonlyduringthose
periods when condensing temperatures and return gas temperatures
are high or in periods where a system failure (such asan iced evaporator,
an expansion valve which does not control superheat, blocked
condenser, or a failed condenser fan) raises condensing temperatures
or return gas temperatures to abnormally high levels or lowers suction
pressure to abnormally low levels.

Head Pressure Control
Several types of head pressure control systems are available on
condensing units:
A. Dual Valve System. (See section on operation
and adjustment.)
B. Single Valve system. No adjustments are necessary.
(See section on operation.)
C. Ambient Fan Cycle Control. (See section on operation
and adjustment.)
D. No Control.
A. Dual Valve System
The system employs an ORI (open on rise of inlet pressure) valve and
an ORD ( open on rise of differential pressure) valve.The high pressure
discharge gas is introduced above the liquid in the receiver tank. The
receiver discharge is regulated by the ORI valve.
The-discharge pressure of the ORI valve must be adjusted to regulate
the unit for proper operating conditions. Adjust the ORI valve shown
on the following diagram to maintain a discharge pressure of 160 to
180 PSIG.
B. Single Valve System
The standard valve used on high pressure refrigerant systems controls
the head pressure at approximately 180 PSIG. There is no adjustment
for this valve. On low pressure refrigerant systems the valve controls
pressure at approximately 100 PSIG. For energy efficiency, the 100 PSIG
valve issometimes used on high pressure refrigerantsystems.When this
is done, refer to Table 1 on page 5 for expansion valve selections.
At condensing pressures above the valve setting, flow enters Port C
and leaves Port R. When the condensing pressure falls below the valve
setting, the valve modulates to permit discharge gas to enter Port D.
Metering discharge gas into the refrigerantflowleaving the condenser
produces a higher pressure at the condenser outlet, reduces the flow,
and causes the level of liquid refrigerant to rise in the condenser.
This "flooding" of the condenser with liquid refrigerant reduces the
available condensing surface, holding the condensing pressure at
the valve setting.
C. Ambient Fan Cycle Control
This is an automatic winter control method which will maintain a
condensing pressure within reasonable limits by cycling fan motors
in response to outside air temperature. The thermostat(s) should be
field adjusted to shut off the fan when the condensing temperature
is reduced to approximately 90.F. Table 7 lists approximate settings
for several system T.D.s.These settings are approximate as they do not
take into account variations in load.
CAUTION: Under no circumstance should all condenser
motors be allowed to cycle off on one control.
At least one motor shall be wired to operate
at all times. Under most circumstances, the
condenser motor nearest the inlet header
should remain on whenever the compressor
is operating.
Operation and Adjustment
Condensing units with dual valves require sufficient charge to partially
flood the condenser during low ambient conditions.
Valve adjustment should be made with gauges connected to the
discharge port of the com pressor. Adjustments should be made during
mild or low ambient conditions.Turning the valve stem "clockwise "on
the ORI valve will increase the discharge pressure, while turning the
valve stem "counterclockwise " will decrease the discharge pressure.
If adjustments a re made during warm ambient conditions, it may not be
possible to adjust the regulator valve as low as desired. Readjustment
may be necessary once cooler conditions prevail.

Refrigeration Oils*
With the changes that have taken place in our industry due to the CFC
issue, we have reevaluated our lubricants to ensure compatibility with
the new HFC refrigerants and HCFC interim blends offered by several
chemical producers. As a secondary criteria, it is also desirable that any
new lubricant be compatible with the traditional refrigerants such as
HCFC -22 or R502. This "backward compatibility" has been achieved
with the introduction of the Polyol ester lubricants.
Table 8 below summarizes which oils /lubricants are approved for use
in Copeland compressors:
Polyol Ester Lubricants
Hygroscopicity
Ester lubricants (POE) have the characteristic of quickly absorbing
moisture from the ambient surroundings. This is shown graphically in
Figure 16 where it can be seen that such lubricants absorb moisture
faster and in greater quantity than conventional mineral oils. Since
moisture levels greater than 100 ppm will results in system corrosion
and ultimate failure, it is imperative that compressors, components,
containers and the entire system be kept sealed as much as possible.
Lubricants will be packaged in specially designed, sealed containers.
After opening, all the lubricant in a container should be used at once
since it will readily absorb moisture if left exposed to the ambient.
Any unused lubricant should be properly disposed of. Similarly, work
on systems and compressors must be carried out with the open time
as short as possible. Leaving the system or compressor open during
breaks or overnight MUST BE AVOIDED!
Color
Table 8. Refrigeration Oils
As received, the POE lubricant will be clear or straw colored. After use,
it may acquire a darker color. This does not indicate a problem as the
darker color merely reflects the activity of the lubricant's protective
additive.
Oil Level
During Copeland's testing of Polyol ester oil, it was found that this
lubricant exhibits a greater tendency to introduce oil into the cylinder
during flooded start conditions. If allowed to continue, this condition
will cause mechanical failure of the compressor.
A crankcase heater is required with condensing units and it must be
turned on several hours before start -up.
Oil level must not exceed 1/4 sight glass.

Mineral Oils
The BR and Scroll compressors use Sontex 200, a "white oil': This oil is
notsuitablefor lowtemperature applications nor is it available through
the normal refrigeration wholesalers. For field "top - off"the use of 3GS
or equivalent, or Zerol 200TD is permissible, as long as at least 50% of
the total oil charge remains Sontex 200.
Suniso 3GS, Texaco WF32 and Calumet R015 (yellow oils) are available
through normal refrigeration wholesalers.These oils are compatible if
mixed and can be used on both high and low temperature systems.
Polyol Ester Lubricants
The Mobil EAL ARCTIC 22 CC is the preferred Polyol ester due to unique
additives included in this lubricant. ICI Emkarate RL 32S is an acceptable
Polyol ester lubricant approved for use when Mobil is not available.
These POE's must be used if HFC refrigerants are used in the system.
Theyarealsoacceptableforusewith any of the traditional refrigerants or
16
interim blends and are compatible with mineral oils.They can therefore
be mixed with mineral oils when used in systems with CFC or HCFC
refrigerants when Copeland compressors are used. These lubricants
are compatible with one another and can be mixed.
Alkyl Benzenes
Zerol 200TD is an alkyl benzene (AB) lubricant. Copeland recommends
this lubricant for use as a mixture with mineral oil (MO) when using the
interim blends such as R -401 A, R -401 B and R -402A (MP39, MP66 and
HP80). A minimum of 50% AB is required in these mixtures to assure
proper oil return.
Shell MS 2212 is a 70/30 mixture of AB /MO. If this lubricant is used in a
retrofit situation virtually all of the existing MO must be drained prior
to refilling with the MS 2212 to assure a minimum 50% AB content.
Phase Loss Monitor
The combination phase sequence and loss monitor relay protects the
system against phase loss (single phasing), phase reversal (improper
sequence) and low voltage (brownout). When phase sequence is
correct and full line voltage is present on all three phases, the relay is
energized as the normal condition indicator light glows.
Note: If compressor fails to operate and the normal condition indicator
light on the phase monitor does not glow, then the supplied electrical
current is not in phase with the monitor. This problem is easily corrected
by the following steps:
1. Turn power off at disconnect switch.
2. Swap any two of the three power input wires.
3. Turn power on. Indicator light should glow and compressor
should start.
4. Observe motors for correct rotation.
Recommended Refrigerant Piping Practices
The system as supplied by Heatcraft Refrigeration Products, was
thoroughly cleaned and dehydrated at the factory. Foreign matter
may enter the system by way of the evaporator to condensing unit
piping.Therefore, care must be used during installation of the piping
to prevent entrance of foreign matter.
Install all refrigeration system components in accordance with
applicable local and national codes and in conformance with good
practice required for the proper operation of the system.
The refrigerant pipe size should be selected from the tables on pages
23 -29. The interconnecting pipe size is not necessarily the same size
as the stub -out on the condensing unit or the evaporator.
The following procedures should be followed:
(a) Do not leave dehydrated compressors or filter -
driers on condensing units open to the atmosphere
any longer than is absolutely necessary.
(b) Use only refrigeration grade copper tubing,
properly sealed against contamination.
(c) Suction lines should slope 1/4" per 10 feet
towards the compressor.
(d) Suitable P -type oil traps should be located at
the base of each suction riser of four (4) feet or
to enhance oil return to the compressor.
(e) For desired method of superheat measurement,
Figure 17. Example of Pipe Support
more
a pressure tap should be installed in each
evaporator suction line in the proximity of the
expansion valve bulb.
(f) When brazing refrigerant lines, an inert gas
should be passed through the line at low
pressure to prevent scaling and oxidation
the tubing. Dry nitrogen is preferred.
(g) Use only a suitable silver solder alloy on suction
and liquid lines.
(h) Limit the soldering paste or flux to the minimum
required to prevent contamination of the solder
joint internally. Flux only the male portion of the
connection, never the female. After brazing,
remove excess flux.
(i) See Table 11 on page 23 for discharge and liquid
drain line sizes for remote condenser connections.
(j) If isolation valves are installed at the evaporator,
full port ball valves should be "used.
inside
Refrigerant Pipe Support
2.
3.
4.
5.
Normally, any straight run of tubing must be supported in at
least two locations near each end of the run. Long
runs require additional supports. The refrigerant lines should
be supported and fastened properly. As a guide, 3/8 to 7/8
should be supported every 5 feet; 1-1/8 and 1 -3/8
every 7 feet; and 1 -5/8 and 2 -1/8 every 9 to 10
feet.
When changing directions in a run of tubing, no corner
should be left unsupported. Supports should be placed a
maximum of 2 feet in each direction from the corner.
Piping attached to a vibrating object (such as a•compressor
or compressor base) must be supported in such a manner
that will not restrict the movement of the vibrating object.
Rigid mounting will fatigue the copper tubing.
Do not use short radius ells. Short radius elbows have
points of excessive stress concentration and are subject to
breakage at these points.
Thoroughly inspect all piping after the equipment is
in operation and add supports wherever line vibration
is significantly greater than most of the other piping.
Extra supports are relatively inexpensive as compared to
refrigerant loss.

When multiple evaporators are connected in series using a common
suction line,the branch suction lines must enter thetopofthe common
suction line.
For dual or multiple evaporator systems, the branch lines to each
evaporator should be sized for the evaporator capacity. The main
common line should be sized for the total system capacity.
Suction lines that are outside of refrigerated space must be insulated.
See the Line Insulation section on page 31 for more information.

Prefabricated wrought coppertraps areavailable, ora trap can be made
by using two street ells and one regular ell. The suction trap must be
the same size as the suction line. For long vertical risers, additional
traps may be necessary. Generally, one trap is recommended for each
length of pipe (approximately 20 feet) to insure proper oil movement.
See Figure 19 below for methods of constructing proper suction line
P- traps.
NOTE: A suction line trap must be installed at the
point where piping changes the direction of
refrigerant flow from any horizontal run to an
upward vertical run.

METHOD A
Liquid lines should be sized for a minimum pressure drop to prevent
"flashing": Flashing in the liquid lines would create additional pressure
drop and poor expansion valve operation. If a system requires long
liquid lines from the receiver to the evaporator or if the liquid has to
rise vertically upward any distance, the losses should be calculated to
determine whether or not a heat exchanger is required. The use of a
suction to liquid heat exchanger may be used to subcool the liquid to
prevent flashing.This method of subcooling will normally provide no
more than 20.F subcooling on high pressure systems. The amount of

subcooling will depend on the design and size of the heat exchanger
and on the operating suction and discharge pressures. An additional
benefit from the use of the suction to liquid type heat exchanger
is that it can help raise the superheat in the suction line to prevent
liquid return to the compressor via the suction line. Generally, heat
exchangers are not recommended on R -22 low temperature systems.
However, they have proved necessary on short, well insulated suction
line runs to provide superheat at the compressor.
Hot Gas Defrost Systems
Hot Gas Defrost systems can be described as reverse cycle, re-
evap., or alternating evaporator. Please see manual H- IM -HGD for
Mohave"" systems.
Refrigerant Piping
Install all refrigerant components in accordance with applicable
local and national codes and in accordance with good practice
for proper system operation.The thermostatic expansion valve
must be the externally equalized type. It can be mounted inside
the unit end compartment. Mount the expansion valve bulb on
a horizontal run of suction line as close as possible to the suction
header. Use the clamps provided with the valve to fasten the bulb
securely so there is a tight line -to -line contact between the bulb
and the suction line. Suction and hot gas connections are made on
the outside of the unit.
Suction lines should be sloped towards the compressor at the rate
of one (1) inch_per ten (10) feet for good oil return. Vertical risers
of more than four (4) feet should be trapped at the bottom with
a P -trap. If a P -trap is used, the expansion valve bulb should be
installed between the unit and the trap.
Reverse Cycle System
The hot gas unit coolers can be used in reverse cycle hot gas
defrost systems using multiple evaporators connected to one
condensing unit. Generally, not more than one -third of the
system defrosts at one time. During the reverse cycle defrost, the
reversing valve, located in the compressor discharge line, diverts
hot gas through the suction line to the evaporator.
See the piping view in the Reverse Cycle Defrost Piping diagram.
The suction line check valve directs the hot gas through the drain
pan loop which prevents condensate in the pan from freezing.
The hot gas exits the loop at the pan loop outlet header and
enters the evaporator through the check valve assembly. As the
hot gas defrosts the coil, heat is removed from the hot gas and
eventually it condenses into a liquid and exits the coil at the
distributor side port. The liquid then flows through the check valve
of the thermostatic expansion valve bypass assembly, around the
thermostatic expansion valve, and into the system liquid Iine.The
liquid refrigerant then feeds other evaporators on the cooling
cycle, evaporates, and returns to the compressor through their
suction lines.
Three Pipe System
The three pipe-system (sometimes called re- evap.) uses three
pipes: one for liquid line, one for suction line, and one for hot gas
line. In addition, a re- evaporator accumulator is used at the suction
outlet of the evaporator. The hot gas is taken from the discharge
line between the compressor and the condenser, through a
hot gas solenoid valve, then to the evaporator drain pan circuit,
distributor tee, through the coil. See the Three -Pipe Defrost Piping
Diagram on p. 20 for typical piping at the evaporator coil.

Alternating Evaporator System
in the alternating evaporator hot gas defrost system, a third line is
taken off the compressor discharge line as the re -evap system. It
is piped with solenoids at each evaporator, so that hot gas defrost
is accomplished on one or more evaporators while the remaining
IMPORTANT: It is imperative that with the alternating
evaporator hot gas defrost system, no more that 25% of the
operating refrigeration load be in defrost at any time.
evaporators continue to function in a normal manner.The liquid from
defrosting evaporators is reintroduced to the main liquid line and it
is necessary that 75% or greater capacity be retained in the normal
refrigeration cycle to offset the capacity that is being removed by the
units on the hot gas defrost.

Pipe size example:
Given: -10 °F Freezer with one system having (2) evaporators
One condensing unit rated at 24,000 BTUH's @ -20 °F SST R404A
refrigerant.
Two evaporators each rated at 12,000 BTUH's @ 10 °F TD.
• 75 feet of actual line run between condensing unit to first
evaporator and 20 feet of actual line run between the first
evaporator and the second evaporator (see figure below).
How to figure line sizes:
1. Determine equivalent line run = actual run + valves and fitting
allowances.
2. - Use Line Sizing Tables on pages 22 -29 to size lines.
3. Note any special considerations.
Line size 2
Evap. 2
Line size 1
Evap. 1
Determine line size 1 (main line from
condensing unit):
1. Main line from the condensing unit to be sized for the total
capacity (balance) of the whole system of 24,000 BTUH's
(Table 14 and 14A).
2. Refer to 24,000 @75 feet at -20 °F SST R404A on the chart.
You will find the suction line to be 1 1/8" and 1/2" liquid line.
3. Refer to Table 10. For every 1 1/8" 90° elbow you must add
3 equivalent feet of pipe and 2 equivalent feet of pipe for each
1 1/8" tee.
Therefore, total equivalent line run =
Actual line run
+ (6) 1 1/8" elbows @ 3'
+ (1) 1 1/8" tee @ 2'
75 feet
18 feet
2 feet
Total equivalent line run 95 feet
4. Refer to Table 14A. For 95 total equivalent feet, the suction
line size should be 1 3/8" and the liquid line stays at 1/2" line.
Note: The gray shaded areas on Table 14. For 24,000 BTUH's, the
maximum suction riser is 11/8" to insure proper oil return and pressure
drop from the bottom p -trap to the top p -trap.

Fittings in this system:
(6) 90° elbows in main line plus a 90° turn through

(5) addtional 90° elbows to first evaporator.
(4) additional 90° elbows to second evaporator.
Determine line size 2 (evaporators):
Line sizing to each evaporator is based on 12,000 BTUH's and
equivalent run from condensing unit. First evaporator has an 80
ft run and the second evaporator has a 95 ft. run.
2. Table 14 indicates 7/8" suction for the first evaporator and Table
14A indicates 1 1/8" suction for the second evaporator.
3. Refer to Table 10. Each 7/8" 90° elbow adds 2 equivalent feet of
pipe. Each 1 1/8" 90° elbow adds 3 equivalent feet and a 90° turn
through a 1 1/8" tee adds 6 equivalent feet.
4. Actual line run (evap 1) 80 feet

NOTES:
1. Sizes that are highlighted indicate maximum suction line sizes that should be used for risers. Riser size should not exceed horizontal size.
Properly placed suction traps must also be used for adequate oil return.
All sizes shown are for O.D. Type L copper tubing.
2. Suction line sizes selected at pressure drop equivalent to 2 °F. Reduce estimate of system capacity accordingly.
3. Recommended liquid line size may increase with reverse cycle hot gas systems.
4. Consult factory for R -134a operation at winter conditions below 0° ambient.
Heated and insulated receiver required below 0° ambient.
If system load drops below 40% of design, consideration to installing double suction risers should be made.

* NOTES;
1. Sizes that are highlighted indicate maximum suction line sizes that should be used for risers. Riser size should not exceed horizontal size.
Properly placed suction traps must also be used for adequate oil return.
All sizes shown are for O.D. Type L copper tubing.
2. Suction line sizes selected at pressure drop equivalent to 2-F. Reduce estimate of system capacity accordingly.
3. Recommended liquid line size may increase with reverse cycle hot gas systems.
4. Consult factory for R -134a operation at winter conditions below 0° ambient.
Heated and insulated receiver required below 0° ambient.
If system load drops below 40% of design, consideration to installing double suction risers should be made.

* NOTES:
1. Sizes that are highlighted indicate maximum suction line sizes that should be used for risers. Riser size should not exceed horizontal size.
Properly placed suction traps must also be used for adequate oil return.
All sizes shown are for O.D. Type L copper tubing.
2. Suction line sizes selected at pressure drop equivalent to TF. Reduce estimate of system capacity accordingly.
3. Recommended liquid line size may increase with reverse cycle hot gas systems.
4. If system load drops below 40% of design, consideration to installing double suction risers should be made.

1. Sizes that are highlighted indicate maximum suction line sizes that should be used for risers. Riser size should not exceed horizontal size.
Properly placed suction traps must also be used for adequate oil return.
All sizes shown are for 0.D. Type L copper tubing.
2. Suction line sizes selected at pressure drop equivalent to 2'F. Reduce estimate of system capacity accordingly.
3. Recommended liquid line size may increase with reverse cycle hot gas systems.
4. If system load drops below 40% of design, consideration to installing double suction risers should be made.

City & Tower Water Connections
In the refrigeration industry "City" and "Tower" are designations of
temperature and flow conditions, not applications. The term "City"
refers to operating conditions where incoming water is 75 °F, and
condensing temperature is 105°F."Tower"refers to a highertemperature
relationship which is normally 85 °F, incoming water and 105 °F
condensing temperature.
Water circuits in some condenser models provide a center, or Tower,
outlet connection to allow divided inlet water flow. This extra water
port reduces water velocity, water pressure drop, and condenser wear
in applications such as cooling towers where higher inlet temperatures
and water flows occur.
Water Connections for City
ForCitywater(open system)
high pressure applications,

Water Connections
for Tower
For Tower usage and low
pressure applications, both
normal water connections
will be used as inlets and
the tower connection as
an outlet.

OUT
Evacuation and Leak Detection
Due to the smaller molecule size of HFC's, they will tend to leak more
readily than CFC's. Consequently, it is of the utmost importance
that proper system evacuation and leak detection procedures be
employed.
Copeland recommends a minimum evacuation to 500 microns. In
addition, a vacuum decaytest is strongly recommended to assure there
is not a large pressure differential between the system and vacuum
pump. Good evacuation processes include frequent vacuum pump oil
changes and large diameter, short hose connections to both high and
low sides of the system preferably using bronze braided hose.
Leak detection can be carried out in the conventional manner.
If HCFC or CFC tracer gas is used, care must be taken to completely
remove all traces of the gas prior to introducing HFC's.
Electronic leak detectors are now available that will sense HFC's. This
is considered preferable since it removes the possibility of chlorine
remaining in the system after leak testing with HCFC's and /or CFC's.
There is a view that even small quantities of chlorine may act as a
catalyst encouraging copper plating and /or corrosion and should
therefore be avoided.
WARNING: HFC -134a has been shown to be
combustible at pressure as low as 5.5 psig
(at 350°F) when mixed with air at
concentrations more than 60% air
by volume.
At lower temperature, higher pressures are
required to support combustion. Therefore,
air should never be mixed with HFC -134a
for leak detection.
Within the last several years, manufacturers have developed fluorescent
dye leak detection systems for use with refrigerants. These dyes mix
with the lubricant and, when exposed to an ultraviolet light "fluoresce"
indicates the location of leaks. Copeland has tested and approved
the Rigid "System Safe" dye and found it to be compatible with the
compressor materials in systems.
Leak Testing
After all lines are connected, the entire system must be Ieaktested.The
complete system should be pressurized to not more than 150 psig with
refrigerant and dry nitrogen (or dry CO2).The use of an electronic type
leakdetectoris highly recommended because ofitsgreatersensitivityto
small Teaks. As a further check it is recommended that this pressure be
held for a minimum of 12 hours and then rechecked. For a satisfactory
installation, the system must be leak tight.
Line Insulation
After the final leak test, refrigerant lines exposed to high ambient
conditions should be insulated to reduce heat pickup and prevent the
formation of flash gas in the liquid lines. Suction lines must always be
insulated with 3/4 "wall Armstrong "Armaflex "orequal.When required,
Liquid lines should be insulated with 1/2 inch wall insulation or better.
The insulation located in outdoor environments should be protected
from UV exposure to prevent deterioration of insulating value.
Evacuation
CAUTION: Do not use the refrigeration compressor
to evacuate the system. Do not start the
compressor while it is in a vacuum.
A good, deep vacuum pump should be connected to both the low and
high side evacuation valves with copper tube or high vacuum hoses
(1/4" ID minimum). If the compressor has service valves, they should
remain closed. A deep vacuum gauge capable of registering pressure
in microns should be attached to the system for pressure readings.
A shut off valve between the gauge connection and vacuum pump
should be provided to allow the system pressure to be checked after
evacuation. Do not turn off vacuum pump when connected to an
evacuated system before closing shut off valve.
Thevacuum pump should be operated until a pressureof 1,500 microns
absolute pressure is reached — at which time the vacuum should be
broken with the refrigerant to be used in the system through a drier
until the system pressure rises above "0" psig.
NOTE: Refrigerant used during evacuation cannot
be vented. Reclaim all used refrigerant.
EPA regulations are constantly being
updated to ensure your procedure follows
correct regulations.
Repeat this operation a second time.
Open the compressor service valves and evacuate the entire system
to 500 microns absolute pressure. Raise the pressure to 2 psig with
the refrigerant and remove the vacuum pump.

'Refrigerant Charging Instructions
1. Install a liquid line drier in the refrigerant supply line between
the service gauge and the liquid service port of the receiver. This
extra drier will insure that all refrigerant supplied to the system is
clean and dry.
2. When initially charging a system that is in a vacuum, liquid
refrigerant can be added directly into the receiver tank.
3. Check equipment catalog for refrigerant capacity. System
refrigerant capacity is 90% of receiver capacity. Do not add more
refrigerant than the data tag indicates, unlessthe line run exceeds
25ft.Then, add additional refrigerant as per the chart on page 30.
Weigh the refrigerant drum before charging so an accurate record
can be kept of the weight of refrigerant put in the system.
4. Start the system and finish charging until the sight glass indicates
a full charge and the proper amount has been weighed in. If the
refrigerant must be added to the system through the suction
sideofthe compressor, charge in vapor form only. Liquid charging
must bedone in the high sideonlyorwith liquid metering devices
to protect the compressor.
Low Head Pressure Systems
If you are charging the system by using a clear sight glass as an indication
of proper charge the following must be considered.
Check the condensing temperature. It must be above 105 °F.Ifnot, it will
be necessary to reduce the amount of air going through the condenser
from fans still running. Simply reduce the effective condenser face area
to raise the discharge pressure above the equivalent 105 °F condensing
temperature and then proceed to charge to clear the sightglass. Adjust
evaporator superheat at this time. Return to full condenser face area
and allow the system to balance.
Field Wiring
WARNING: All wiring must be done in accordance with
applicable codes and local ordinances.
The field wiring should enter the areas as provided on the unit. The
wiring diagram for each unit is located on the inside of the electrical
panel door. All field wiring should be done in a professional manner
and in accordance with all governing codes. Before operating unit,
double check all wiring connections, including the factory terminals.
Factory connections can vibrate loose during shipment.
1. The serial data tag on the unit is marked with the electrical
characteristic for wiring the unit.
2. Consult the wiring diagram in the unit cooler and in the con-
densing unit for proper connections.
3. Wire type should be of copper conductor only and of the
proper size to handle the connected load.
4. The unit must be grounded.
5. For multiple evaporator systems, the defrost termination
controls should be wired in series. Follow the wiring diagrams
for multiple evaporator systems carefully. This will assure com-
plete defrost of all evaporators in the system.
6. Multiple evaporator systems should operate off of one thermo-
stat.
7. If a remote defrost timer is to be used, the timer should be
located outside the refrigerated space.
8. For air cooled condensers, due to multiple low amp motors, we
recommend using time delay fuse protection instead of circuit
breakers.

Check Out and Start Up
After the installation has been completed, the following points should
be covered before the system is placed in operation:
(a) Check all electrical and refrigerant connections.
Be sure they are all tight.
(b) Observe compressor oil level before start- up.The
oil level should be at or slightly above the 1/4 level
of the sight glass. Refer to Table 8 on page 16 for
proper compressor oil.
(c) Remove upper mounting nuts on the compressor
feet. Remove the shipping spacers. Install the
neoprene washers onto the compressor feet.
Replace the upper mounting nuts and washers,
allowing 1/16" space between the mounting nut and
the neoprene spacer.
(d) Check high and low pressure controls, pressure
regulating valves, oil pressure safety controls, and
all other safety controls, and adjust if necessary.
(e) Check the room thermostat for normal operation
and adjust.
(f) Wiring diagrams, instruction bulletins, etc. attached
to the condensing units should be read and filed for
future reference.
(g) All fan motors on air cooled condensers,
evaporators, etc. should be checked for proper
rotation. Fan motor mounts should be carefully
checked for tightness and proper alignment.
(h) Electric and hot gas evaporator fan motors should
be temporarily wired for continuous operation until
the room temperature has stabilized.
(i) Observe system pressures during charging and
initial operation. Do not add oil while the system is
short of refrigerant unless oil level is dangerously low.
(j) Continue charging until system has sufficient
refrigerant for proper operation. Do not overcharge.
Remember that bubbles in a sight glass may be
caused by a restriction as well as a shortage of
refrigerant.
(k) Do not leave unit unattended until the system has
reached normal operating conditions and the oil
charge has been properly adjusted to maintain the oil
level between 1/4 and bottom of the sight glass.
(I) Make sure all Schrader valve caps are in place and
tight
CAUTION:Extreme care must be taken in starting
compressors for the first time after system
charging. At this time, all of the oil and most
of the refrigerant might be in the compressor
creating a condition which could cause
compressor damage due to slugging.
Activating the crankcase heater for 24 hours
prior to start -up is required. If no crankcase
heater is present, then directing a 500 watt
heat lamp or other safe heat source on the
lower shell of the compressor for approximately
thirty minutes will be beneficial in eliminating
this condition which might never reoccur.
WARNING:Scroll compressor is directional
dependent. If noisy, change phase of input
wiring.
Operational Check Out
After the system has been charged and has operated for at least
two hours at normal operating conditions without any indication of
malfunction, it should be allowed to operate overnight on automatic
controls. Then a thorough recheck of the entire system operation
should be made as follows:
(a) Check compressor discharge and suction pressures.
If not within system design limits, determine why
and take corrective action.
(b) Check liquid line sight glass and expansion valve
operation. If there are indications that more
refrigerant is required, leak test all connections and
system components and repair any Teaks before
adding refrigerant.
(c) Observe oil level in compressor crankcase sight
glass. Add oil as necessary to bring level to bottom
1/4 of the sight glass.
(d) Thermostatic expansion valves must be checked
for proper superheat settings. Feeler bulbs must be
in positive contact with the suction line and should
be insulated. Valves set at high superheat will lower
refrigeration capacity. Low superheat promotes
liquid slugging and compressor bearing washout.
(e) Using suitable instruments, carefully check line
voltage and amperage at the compressor terminals.
Voltage must be within 10% of that indicated on the
condensing unit nameplate. If high or low voltage is
indicated, notify the power company. If amperage
draw is excessive, immediately determine the cause
and take corrective action. On three phase motor
compressors, check to see that a balanced load is
drawn by each phase.
(f) The maximum approved settings for high pressure
controls on our air cooled condensing equipment
is 425 psig. On air cooled systems, check as follows:
Disconnect the fan motors or block the condenser inlet
air. Watch high pressure gauge for cutout point.
Recheck all safety and operating controls for proper
operation and adjust if necessary.
(g) Check defrost controls for initiation and termination
settings, and length of defrost period. Set fail safe at
length of defrost + 25 %.
Example: 20 minute defrost + 5 minutes
= 25 minute fail safe
(h) Check drain pan for proper drainage.
(i) Check winter head pressure controls for pressure
setting.
(j) Check crankcase heater operation if used.
(k) Install instruction card and control system diagram for
use of building manager or owner.
NOTE: All adjustable controls and valves must be field
adjusted to meet desired operation. There are no
factory preset controls or valve adjustments.
This includes low pressure, high pressure,
adjustable head pressure systems and expansion
valves.
System Balancing - Compressor Superheat
IMPORTANT: In orderto obtain the maximum capacityfrom
a system, and to ensure trouble -free opera-
tion, it is necessary to balance each and every
system.
This is extremely important with any refrigeration system.
The critical value which must be checked is suction superheat.
Suction superheat should be checked at the compressor as
follows:
1. Measure the suction pressure at the suction service
valve of the compressor and determine the saturation
temperature corresponding to this pressure from a
"Temperature - Pressure" chart.
2. Measure the suction temperature of the suction line
about one foot back from the compressor using an
accurate thermometer.
3. Subtract the saturated temperature from the actual
suction line temperature.The difference is superheat.
Too low a suction superheat can result in liquid being returned to the
compressor. This will cause dilution of the oil and eventual failure of
the bearings and rings or in the extreme case, valve failure.
Too high a suction superheat will result in excessive discharge
temperatures which cause a breakdown ofthe oil and results in piston
ring wear, piston and cylinder wall damage.
It should also be remembered thatthe system capacity decreases as the
suction superheat increases. For maximum system capacity, suction
superheat should be kept as low as is practical. Copeland mandates a
minimum superheat of20 °F atthecompressor. We recommend that
the superheat at the compressor be between 20°F and 30T.
If adjustments to the suction superheat need to be made,
the expansion valve at the evaporator should be adjusted.
See instructions on page 34.
33
Evaporator Superheat
Check Your Superheat. After the box temperature has reached or is
close to reaching the desired temperature, the evaporator superheat
should be checked and adjustments made if necessary. Generally,
systems with a design TD of 10'F should have a superheat value of 6'
to 10'F for maximum efficiency. For systems operating at higherTD's,
the superheat can be adjusted to 12' to 15' °F as required.
of 20 °F may override these recommendations
on some systems with short line runs.
To properly determine the superheat of the evaporator, the following
procedure is the method Heatcraft recommends:
WARNING: Ifthe condensing unit has no flooded con-
denser head pressure control, the condens-
ing unit must have the discharge pressure
above the equivalent 105 °F condensing
pressure. See refrigerant charging instruc-
tions on page 32.
Measure the temperature of the suction line at the point
the bulb is clamped.
2. Obtain the suction pressure that exists in the suction line
at the bulb location by either of the following methods:
a. A gauge in the external equalized line will indicate the
pressure directly and accurately.
b. A gauge directly in the suction line near the
evaporator or directly in the suction header of the
evaporator will yield the same reading as 2a above.
3. Convert the pressure obtained in 2a or 2b above to
saturated evaporator temperature by using a
temperature - pressure chart.
4. Subtract the saturated temperature from the actual
suction line temperature. The difference is Superheat.
Alternative Superheat Method
The most accurate method of measuring superheat is found by
following the previous procedure, Temperature /Pressure method.
However, that method may not always be practical. An alternative
method which will yield fairly accurate results is the temperature /
temperature method:
1. Measure the temperature of the suction line at the
point the bulb is clamped (outlet).
2. Measure the temperature of one of the distributor
tubes close to the evaporator coil (inlet).
3. Subtract the inlet temperature from the outlet
temperature. The difference is Superheat.
This method will yield fairly accurate results as long as the pressure
drop through the evaporator coil is low.
34
General Sequence of Operation
Refrigeration Cycle
1. Power is supplied to the timer at terminals "1 "and "N':
2. The fan delay and the defrost termination thermostat is closed in the
fan delay position and open in the defrost termination position.
The unit cooler fans run continuously.
3. The defrost heaters are off.
4. The room thermostat closes when the temperature rises
above the desired setting.
5. The liquid line solenoid is energized and opens, which allows liquid
refrigerant to flow through the unit cooler.
6. The low pressure control closes when the suction pressure rises
above the cutin setting of the control.
7. On systems with oil pumps, the oil safety control is closed. If the net
oil pressure is less than 9 PSIG for more than 120 seconds, the oil
safety opens, thus breaking the circuit to the compressor contactor
holding coil. The compressor will not operate. This control is reset
manually and must be reset before the compressor can be
restarted.
8. The compressor contactor closes. The compressor and condenser
fan start simultaneously.
9. The room temperature gradually decreases to the desired
temperature.
10. Once the desired temperature is reached, the thermostat opens and
the liquid line solenoid closes, stopping refrigerant flow through the
evaporator.
11. Suction pressure decreases and the compressor contactor opens
when the pressure drops below the cutout setting on the low pressure
control. The compressor and condenser fan stop running.
12. This cycle is repeated as many times as necessary to satisfy the room
thermostat.
13. Frost starts to form on the evaporator coil and continues to form until
the defrost cycle is initiated.
Defrost Cycle
1. The defrost cycle starts automatically by the timer at
predetermined times. Typical settings are two to four
defrost cycles per day for freezers. For heavier frost loads
additional settings may be required.
2. Switch "2 "to "4" opens in the time clock which breaks the
circuit to the room thermostat, liquid line solenoid, and
evaporator fan motors, allowing the compressor to pump
down and shut off. Simultaneously switch "1" to"3" closes
in the timer allowing current to flow to one side of the
defrost heater contactor. When the compressor shuts off,
an auxiliary contact will send power to the contactor holding
coil; thus, energizing the defrost heaters.
3. The heaters raise the temperature of the coil to 32.F
causing the frost to melt off the coil.
4. When the coil warms to 45 °F to 55 °F, the defrost
termination thermostat closes, which allows current to the
switching solenoid in the timer allowing the refrigeration
cycle to begin again.
5. The evaporator heaters are off. If the termination
thermostat fails to close, the fail -safe set on the timer will
terminate defrost.
6. The low pressure control closes and the compressor will
start.
7. When the coil temperature reaches 23 °F to 30°F, the fan
delay closes. This allows the current to flow to the fan
motors.The fan motors start running.
8. The system will now operate in the refrigeration cycle until
another defrost period is initiated by the timer.
Electric Defrost Troubleshooting
The electric defrost units are relatively simple and trouble -free in operation:
Timer
If the system does not go through its proper sequence , check timer operation through a defrost cycle. Check for loose wires or
terminals. Before replacing timer, check other components.
Operation of Paragon Timer
To set time of day grasp knob which is in the center of the inner (fail -safe) dial and rotate it in a counter - clockwise direction. This
will cause the outer (24 hour) dial to revolve. Line up the correct time of day on the outer dial with the time pointer. Do not try to
set the time control by grasping the other (24 hour) dial. Place pins in the outer dial at the time of day that defrost is required.
Operation of Grasslin Timer
To set the time, turn the minute hand clockwise until the time of day (and AM or PM) on the outer dial is aligned with the triangle
marker on the inner dial. Do not rotate minute hand counter - clockwise. Move the white tab (tripper) on the outer dial outward
at each desired initiation time. Each white tab (tripper) is a 15 minute interval and provides 15 minutes of defrost. For longer
defrost duration, move additional tabs (following in time) from the initiation tab. For example, if a 45 minute defrost is to start
at 7:00 AM, move the tabs outward that lie between 7:00 - 7:15, 7:15 - 7:30 and 7:30 - 7:45 on the AM side of the dial.The defrost
will initiate at 7:00 AM and time terminate at 7:45 AM (if temperature termination does not occur first). For models with plastic
cover on timer assembly; re- install cover after adjustment.
Fan Motor
If the motor does not operate or it cycles on thermal overload, remove motor leads from terminal block and apply correct voltage
across the leads. If motor still does not operate satisfactorily, it must be replaced. Before starting the unit, rotate fan blades to
make sure they turn freely and have sufficient clearance.
Fan Delay & Defrost Termination Control
This control is a single pole double throw switch. The red lead wire is wired to common. The black wire is wired in series with
the fan motors. The brown wire is wired in series with the defrost termination solenoid in the timer. The brown and red contacts
close and the black and red contacts open when the temperature is above 55 °F. The black and red contacts close and the brown
and red contacts open when the temperature is below 35 °F.
On initial "pull down" of a warm box the fan will not start until the coil temperature reaches approximately 35 °F. If the box is still
comparatively warm (60 °F) when the fan starts, then blowing this warm air over the coil may cause it to warm up to 55 °F and thus
stop the fan. Therefore, the fan may recycle on initial "pull down" This control cannot be adjusted.
If the fan motor fails to start when the control is below 35 °F, disconnect the fan motor leads and check the motor as described
for fan motors. Also check whether current is being supplied at "N" and "4 "from the timer. The fan delay control must be below
35 °F when checking for a closed circuit.
Defrost Heater
If unit shows very little or no defrosting and does not heat, disconnect heater and check to find if it is burned out. To test, apply
correct voltage across heater or use continuity flashlight battery tester.
Drain Pan
If drain pan has an ice build -up, drain line may be frozen. The drain line should be pitched sharply and exit cabinet as quickly
as possible. Sometimes location and ambient at the drain outside of cabinet may cause freeze -up. A drain line heater may be
required to correct the freeze -up. Any traps in the drain line must be located in a warm ambient.
NOTE: After correcting faulty condition it is
essential that the coil and unit be free of
ice before placing unit back on automatic
operation.
35
NOTES:
1. Lockout relays or normally closed switch of auxiliary
contact on the compressor contactor may be wired to
defrost contactor. Its purpose is to prevent energizing
of the defrost heaters until the compressor has pumped
down and stopped, thus keeping power demand to a
minimum.
2. If the control voltage is to remain energized for any
period of time with the compressor disabled, remove the
defrost clock pins to prevent the defrost heaters from
energizing.
3. A Preventative Maintenance schedule should be set up
as soon as possible after start -up to maintain equipment
integrity.

Preventive Maintenance
Unit Coolers
At every six month interval, or sooner if local conditions cause clogging
or fouling of air passages through the finned surface, the following
items should be checked.
1) Visually inspect unit
• Look for signs of corrosion on fins, cabinet, copper
tubing and solder joints.
Look for excessive or unusual vibration for fan blades
or sheet metal panels when in operation. Identify fan
cell(s) causing vibration and check motor and blade
carefully.
Look for oil stains on headers, return bends, and coil
fins. Check any suspect areas with an electronic leak
detector.
Check drain pan to insure that drain is clear of debris,
obstructions or ice buildup and is free draining.
2) Clean evaporator coil and blades
• ' Periodic cleaning can be accomplished by using a brush,
pressurized water or a commercially available evaporator
coil cleaner or mild detergent. Never use an acid
based cleaner. Follow label directions for appropriate
use. Be sure the product you use is approved for use in
your particular application.
Flush and rinse coil until no residue remains.
• Pay close attention to drain pan, drain line and trap.
3) Check the operation of all fans and ensure airflow is
unobstructed
• Check that each fan rotates freely and quietly. Replace
any fan motor that does not rotate smoothly or makes an
unusual noise.
• Check all fan set screws and tighten if needed.
• Check all fan blades for signs of stress or wear.
Replace any blades that are worn, cracked or bent.
• Verify that all fan motors are securely fastened to the
motor rail.
• Lubricate motors if applicable.
4) Inspect electrical wiring and components
• Visually inspect all wiring for wear, kinks, bare areas and
discoloration. Replace any wiring found to be damaged.
• Verify that all electrical and ground connections are
secure, tighten if necessary.
• Check operation /calibration of all fan cycle and
defrost controls when used.
• Look for abnormal accumulation of ice patterns and
adjust defrost cycles accordingly
• Compare actual defrost heater amp draw against unit
data plate.
• Visually inspect heaters to ensure even surface contact
with the coil. If heaters have crept, decrease defrost
termination temperature and be sure you have even coil
frost patterns. Re -align heaters as needed.
• Check drain line heat tape for proper operation
(supplied and installed by others).
5) Refrigeration Cycle
• Check unit cooler superheat and compare reading for
your specific application
• Visually inspect coil for even distribution

Air Cooled Condensing Units
Quarterly
1) Visually inspect unit
Look for signs of oil stains on interconnection piping and
condenser coil. Pay close attention to areas around
solder joints, building penetrations and pipe clamps.
Check any suspect areas with an electronic leak detector.
Repair any leaks found and add refrigerant as needed.
Check condition of moisture indicator /sightglass in the
sight glass if so equipped. Replace liquid line drier if there
is indication of slight presence of moisture. Replace
refrigerant, oil and drier if moisture concentration is
indicated to be high.
Check moisture indicator /sightglass for flash gas. If found
check entire system for refrigerant leaks and add
refrigerant as needed after repairing any leaks.
Check compressor sightglass (if equipped) for
proper oil level.
• Check condition of condenser. Look for accumulation
of dirt and debris (clean as required).
• Check for unusual noise or vibration. Take corrective
action as required.
• Inspect wiring for signs of wear or discoloration and
repair if needed.
• Check and tighten all flare connections.
Semi - Annually
2) Repeat all quarterly inspection items.
3) Clean condenser coil and blades
• Periodic cleaning can be accomplished by using a brush,
pressurized water and a commercially available foam coil
cleaner. If foam cleaner is used, it should not be an acid
based cleaner. Follow label directions for appropriate use.
• Rinse until no residue remains.
4) Check operation of condenser fans
• Check that each fan rotates freely and quietly.
Replace any fan motor that does not rotate smoothly
or makes excessive noise.
Check all fan blade set screws and tighten as required.
Check all fan blades for signs of cracks, wear or stress.
Pay close attention to the hub and spider. Replace blades
as required.
Verify that all motors are mounted securely.
Lubricate motors if applicable. Do not lubricate
permanently sealed, ball bearing motors.
5) Inspect electrical wiring and components
• Verify that all electrical and ground connections are
secure, tighten as required.
Check condition of compressor and heater contactors.
Look for discoloration and pitting. Replace as required.
Check operation and calibration of all timers, relays
pressure controls and safety controls.
Clean electrical cabinet. Look for signs of moisture, dirt,
debris, insects and wildlife.Take corrective action as
required.
• Verify operation of crankcase heater by measuring amp
draw.
6) Check refrigeration cycle
Check suction, discharge and net oil pressure readings.
If abnormal take appropriate action.
Check operation of demand cooling, liquid injection or
unloaders if so equipped.
Check pressure drop across all filters and driers.
Replace as required.
Verify that superheat at the compressor conforms to
specification. (30 °F to 45 °F)
Check pressure and safety control settings and verify
proper operation.
Annually
7) In addition to quarterly and semiannual maintenance
checks, submit an oil sample for analysis
Look for high concentrations of acid or moisture. Change
oil and driers until test results read normal.
Investigate source of high metal concentrations, which
normally are due to abnormal bearing wear. Look for
liquid refrigerant in the crankcase, low oil pressure or low
superheat as a possible source.
8) Inspect suction accumulator (if equipped)
• If the accumulator is insulated remove insulation and
inspect for leaks and corrosion.
Pay close attention to all copper to steel brazed
connections
Wire brush all corroded areas and peeling paint.
Apply an anticorrosion primer and paint as required.
Re- insulate if applicable.
Air Cooled Condensers and Fluid Coolers
At every six month interval, or sooner if local conditions cause
clogging or fouling of air passages through the finned surface, the
following items should be checked.
1) Visually inspect unit
• Look for Signs of corrosion on fins, cabinet, copper tubing
and solder joints.
• Look for excessive or unusual vibration for fan blades or
sheet metal panels when in operation. Identify fan cell(s)
causing vibration and check motor and blade carefully.
• Look for oil stains on headers, return bends, and coil fins.
Check any suspect areas with an electronic leak detector.
2) Clean condenser coil and blades
• Periodic cleaning can be accomplished by using brush,
pressurized water or a commercially available coil cleaning
foam. If a foam cleaner is used, it should not be an acid based
cleaner. Follow label directions for appropriate use.
• Clear unnecessary trash and debris away from condenser.
3) Check the operation of all fans
• Check that each fan rotates freely and quietly. Replace
any fan motor that does not rotate smoothly or makes an
unusual noise.
• Check all fan set screws and tighten if needed.
• Check all fan blades for sighs of stress or wear. Replace any
blades that are worn, cracked or bent.
• Verify that all fan motors are securely fastened to the motor
rail.
• Lubricate motors if applicable (most Heatcraft condenser
motors are permanently sealed ball bearing type and do not
require lubrication)
4) Inspect electrical wiring and components
• Visually inspect all wiring for wear, kinks, bare areas and
discoloration. Replace any wiring found to be damaged.
• Verify that all electrical and ground connections are secure,
tighten if necessary.
• Check operation /calibration of all fan cycle controls when
used.
