ponents. Only trained and qualified service personnel should
install, repair, or service air - conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters and replacing filters. All
other operations should be performed by trained service per-
sonnel. When working on air - conditioning equipment, ob-
serve precautions in the literature, tags and labels attached
to the unit, and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire ex-
tinguisher available for all brazing operations.
0 WARNING
Before performing service or maintenance operations on
unit, turn off main power switch to unit. Electrical shock
could cause personal injury.
lull be level. This is necessary for unit drain to
operly. Unit leveling tolerances are shown in
er to Accessory Roof Curb Installation Instruc-
Iditional information as required.
UNT (Horizontal Units Only) — Provide a level
ab that extends a minimum of 6 in. beyond unit
'tall a gravel apron in front of condenser coil air
vent grass and foliage from obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
Step 2 — Field Fabricate Ductwork — Secure all
ducts to roof curb and building structure on vertical dis-
charge units. Do not connect ductwork to unit. For horizon-
tal applications, field - supplied flanges should be attached to
horizontal discharge openings and all ductwork should be
attached to the flanges. Insulate and weatherproof all exter-
nal ductwork, joints, and roof openings with counter flash-
ing and mastic in accordance with applicable codes.
Ducts passing through an unconditioned space must be
insulated and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return
should be ducted through the roof deck to comply with ap-
plicable fire codes.
A minimum clearance to combustibles is not required around
ductwork on vertical discharge units. On horizontal
discharge units, a minimum clearance of 1.0 in. is required
for the first 12 in. of ductwork. Cabinet return-air static pres-
sure should not exceed –0.35 in. wg with Varislide econo-
mizer, –0.20 in. wg with PARABLADE economizer, or

Step 3 — Install Condensate Drain Line and Ex-
ternal Trap — Condensate drain connections are located
at the bottom and side of the unit. Unit discharge connec-
tions do not determine the use of drain connections; either
drain connection can be used with vertical or horizontal dis-
charge units.
When using the standard side drain connection, make sure
the plug in the alternate bottom connection is tight before
installing the unit.
To use the bottom drain connection for a roof curb in-
stallation, relocate the factory- installed plug from the bot-
tom connection to the side connection. See Fig. 3. The pip-
ing for the condensate drain and external trap can be completed
after the unit is in place.
All units must have an external trap for condensate drain-
age. Install a trap at least 4 in. deep and protect against freeze -
up. See Fig. 4. If drain line is installed downstream from the
external trap, pitch the line away from the 5OHJQ unit at
1 in. per 10 ft of run. Do not use a pipe size smaller than the
unit connection.
Step 4 — Rig and Place Unit — Inspect unit for trans-
portation damage, and file any claim with transportation agency.
Keep unit upright and do not drop. Spreader bars are not
required if top crating is left on unit, and rollers may be used
to move unit across a roof. Level by using unit frame as a
reference. See Table 1 and Fig. 5 for additional information.
Operating weight is shown in Table 1 and Fig. 5.
Lifting holes are provided in base rails as shown in
Fig. 5 and 6. Refer to rigging instructions on unit.
L>, CAUTION
All panels must be in place when rigging.
POSITIONING — Maintain clearance around and above unit
to provide proper airflow and service access. See Fig. 6.
3
A properly"po`sitioned unit will have the following clear-
ances: I/ -in. clearance between roof curb and base rails on
each side and front of unit; 15 /32 -in. clearance between roof
curb and rear of unit. (See Fig. 1, section C -C.)
Do not install wilt in an indoor location. Do not locate
unit air inlets near exhaust vents or other sources of con-
taminated air.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
After unit is in position, remove polyethylene shipping wrap-
per and top crating.

Step 5 — Make Electrical Connections
Ll WARNING
Unit cabinet must have an uninterrupted, unbroken elec-
trical ground to minimize the possibility of personal in-
jury if an electrical fault should occur. This ground may
consist of electrical wire connected to unit ground lug
in control compartment, or conduit approved for elec-
trical ground when installed in accordance with NEC
(National Electrical Code), ANSI /NFPA (American Na-
tional Standards Institute/National Fire Protection As-
sociation) 70 (latest year), and local electrical codes. Failure
to follow this warning could result in the installer being
liable for personal injury of others.
FIELD POWER SUPPLY —All units except 208/230 -v units
are factory wired for the voltage shown on the nameplate. If
the 208/230 -v unit is to be connected to a 208 -v power sup-
ply, the transformer must be rewired by disconnecting the
black wire from the 230 -v orange wire on the transformer
and connecting it to the 200 -v red wire from the transformer.
The end of the orange wire must then be insulated.
Refer to unit label diagram for additional information. Pig-
tails are provided for field wire connections, Use factory -
supplied splices or UL (Underwriters' Laboratories) approved
copper /aluminum connector.
4
When installing units, provide a disconnect per the NEC.
All field wiring must comply with the NEC and local
requirements.
Install field wiring as follows:
1. Install conduit through side panel openings. For units with-
out electric heat, install conduit between disconnect and
control box.
2. Install power lines to terminal connections as shown in
Fig. 7.
3. For units with electric heat, refer to Accessory Electric
Heat Installation Instructions.
During operation, voltage to compressor terminals must
be within range indicated on unit nameplate (also see
Tables 2A and 2B). On 3 -phase units, voltages between phases
must be balanced within 2% and the current within 10 %.
Use the formula shown in Tables 2A and 2B, Note 2, on
page 10 to determine the percentage of voltage imbalance.
Operation on improper line voltage or excessive phase im-
balance constitutes abuse and may cause damage to electri-
cal components. Such operation invalidates any applicable
Carrier warranty.
NOTE: If accessory thru -the- bottom connections and roof
curbs are used, refer to the thru -the- bottom accessory instal-
lation instructions for information on wiring the unit.

'Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or
480 v. If power distribution voltage to unit varies from rated heater voltage,
heater kW will vary accordingly.
tHeaters are field Installed only.
"Fuse or HACR circuit breaker.
(Electrical disconnect cannot be used if electric heater is installed.
NOTES:
1. In compliance with NEC requirements for muttimotor and combination load
equipment (refer to NEC Articles 430 and 440), the overcurrent protective
device for the unit shall be fuse or HACR breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater
than 2 %. Use the following formula to determine the percentage of voltage
Imbalance.
FIELD CONTROL WIRING — Install a Carrier - approved
accessory thermostat assembly according to installation in-
structions included with the accessory. Locate thermostat as-
sembly on a solid wall in the conditioned space to sense av-
erage temperature in accordance with thermostat installation
instructions.
Route thermostat cable or equivalent single leads of col-
ored wire from subbase terminals to low - voltage connec-
tions on unit (shown in Fig. 8) as described in Steps 1 through
3 below.
NOTE: For wire runs up to 50 ft, use no. 18 AWG (Ameri-
can Wire Gage) insulated wire (35 C minimum). For 50 to
75 ft, use no. 16 AWG insulated wire (35 C minimum). For
over 75 ft, use no. 14 AWG insulated wire (35 C minimum).
All wire larger than no. 18 AWG cannot be directly con-
nected to the thermostat and will require a junction box and
splice at the thermostat.

Determine maximum deviation from average voltage:
{AB) 457 — 452 = 5 v
BC)464- 457 =7v
AC) 457 — 455 = 2 v
Maximum deviation is 7 v.
Determine percentage of voltage imbalance:
% Voltage Imbalance = 100 x 57
= 1.53%
This amount of phase Imbalance is satisfactory as It is below the maximum
allowable 2 %.
IMPORTANT: If the supply voltage phase imbalance is more than 2 %,
contact your local electric utility company immediately.
I. Connect thermostat wires to screw terminals of low volt-
age connection board.
2. Pass the control wires through the hole provided in the
corner post.
3. Feed wire through the raceway built into the corner post
to the 24 -v barrier located on the left side of the control
box. See Fig. 9. The raceway provides the UL- required
clearance between the high- and low - voltage wiring.
DEFROST BOARD — The defrost board timer is set for a
30 minute defrost cycle from the factory. To adjust to a 50
or 90 minute cycle, remove the wire connected to the
30 minute quick connect on the defrost board. See Fig. 10.
Connect lead to the 50 or 90 minute quick connect on the
defrost board, depending on the application.

moved from the filter section.
3. Assemble outdoor -air hood top and side plates as shown
in Fig. 12. Install seal strips on hood top and sides. Put
aside screen retainer and retainer screw for later assem-
bly. Do not attach hood to unit at this time.
4. Slide economizer into unit and secure with screws. See
Fig. 19.
NOTE: Be sure to engage rear economizer flange under
tabs in vertical return -air opening.
5. Insert economizer plug into economizer harness. Re-
move tape from barometric relief damper. See Fig. 19.
6. It' ventilation air is not required, proceed to Step 7. If
ventilation air is required, perform the following:
a. Make sure the factory- installed jumper is in place across
terminals P and PI on the economizer logic module.
T and TI should be disconnected during adjustment.
b. The 2 potentiometers with slots for adjustment are
located on the face of the economizer logic module.
Turn the lower potentiometer fully clockwise. The
dampers should be fully closed. Turn the potentiom-
13
c.
d.
eter g idually counterclockwise until the desired po-
sition is reached.
Connect T and TI to the 24 v power supply.
After installation is complete, calculate the mini-
mum airflow across the economizer. To calculate the
minimum airflow, the following data is needed: total
cfm (cfm3), temperature of the total cfm (T3), tem-
perature of the return air (T2), and temperature of the
entering outside air (T,). Cfm, is the outside air cfm,
which will be the minimum airflow.
Insert the data into the following equations:
T, (cfm,) + T2 (cfm2)
cfm3
cfm2 = (cfm3 – cfm,)
Therefore:
T, (cfm,) + T, (cfm3 – cfm,)
— T3
cfm3 — T3
Use this equation to determine cfm,, which is the mini-
mum airflow across the economizer.
(T3 – T2) cfm3
cfm, – (T, – T2)
If cfm, does not match the desired minimum airflow
from Step 1, re- adjust the minimum position setting
screw.
7. Determine the enthalpy changeover set point from
Fig. 20. The enthalpy changeover set point should be
set to return the outdoor air damper to the minimum po-
sition when enthalpy rises above the set point. The set-
tings are A, B, C, and D. Set the enthalpy changeover
per the setting in Fig. 20.
8. Replace outdoor -air opening panel using screws from
Step 2. Replace filter access panel. Ensure the filter ac-
cess panel slides along the tracks and is securely en-
gaged. See Fig. 21.
9. Fasten hood top and side plate assembly (Fig. 22) to
outdoor -air opening panel with screws provided.
10. Slide outdoor -air inlet screen into screen track on hood
side plate. While holding screen in place, fasten screen
retainer to hood using screws provided. See Fig. 23 .

Step 7- Adjust Indoor -Fa t-apeed - Adjust indoor -
fan speed to meet jobsite conditions.
Table 3 shows fan rpm at motor pulley settings for the
5OHJQ004 -007 units. Table 4 shows data for indoor -fan mo-
tors. Refer to Tables 5 -12 to determine fan speed settings.
For units with electric heating, required minimum cfm is
900 for 5OHJQ004; 1200 for 5011JQ005; 1500 for 5OHJQ006
and 1800 for 5OHJQ007.
BELT-DRIVE MOTORS - Fan motor pulleys are factory -
set for speed shown in Table 1. Check pulley alignment and
belt tension prior to start -up.
To change fan speed:
1. Shut off unit power supply.
2. Loosen belt by loosening fan motor mounting nuts. See
Fig. 24.
3. Loosen movable pulley flange setscrew (see Fig. 25).
4. Screw movable flange toward fixed flange to increase speed
or away from fixed flange to decrease speed. Increasing
fan speeddticreases load on motor. Do not exceed maxi-
mum speed specified in Table 1.
5. Set movable flange at nearest keyway of pulley hub and
tighten setscrew. (See Table 1 for speed change for each
full turn of pulley flange.)
To align fan and motor pulleys (see Fig. 25):
1. Loosen fan pulley setscrews.
2. Slide fan pulley along fan shaft.
3. Make angular alignment by loosening motor from
mounting.
To adjust belt tension:
1. Loosen fan motor mounting nuts.
2. Slide motor mounting plate away from fan scroll for proper
belt tension (1/2-in. deflection with one finger).
3. Tighten motor mounting nuts.
4. Adjust bolt and tighten nut to secure motor in fixed
position.

i1 WARNING
Failure to observe the following warnings could result
in serious personal injury:
1. Follow recognized safety practices and wear protec-
tive goggles when checking or servicing refrigerant
system.
2. Do not operate compressor or provide any electric
power to unit unless compressor terminal cover is in
place and secured.
3. Do not remove compressor terminal cover until all
electrical sources are disconnected.
4. Relieve all pressure from system before touching or
disturbing anything inside terminal box if refrigerant
leak is suspected around compressor terminals. Use
accepted methods to recover refrigerant.
5. Never attempt to repair soldered connection while re-
frigerant system is under pressure.
6. Do not use torch to remove any component. System
contains oil and refrigerant under pressure. To re-
move a component, wear protective goggles and pro-
ceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from
system using both high - and low- pressure ports.
c. Cut component connection tubing with tubing cut-
ter, and remove component from unit.
d. Carefully unsweat remaining tubing stubs when
necessary. Oil can ignite when exposed to torch
flame.
Proceed as follows to inspect and prepare the unit for
initial start -up:
I. Remove all access panels.
2. Read and follow instructions on all WARNING, CAU-
TION, and INFORMATION labels attached to (or shipped
with) unit.
3. Make the following inspections:
a. Inspect for shipping and handling damages such as bro-
ken lines, loose parts, or disconnected wires.
b. Inspect for oil at all refrigerant tubing connections and
on unit base. Detecting oil generally indicates a re-
frigerant leak. Leak -test all refrigerant tubing connec-
tions using electronic leak detector, halide torch, or
liquid -soap solution.
c. Inspect all field- and factory- wiring connections. Be
sure that connections are completed and tight.
d. Inspect coil fins. If damaged during shipping and han-
dling, carefully straighten fins with a fin comb.
4. Verify the following conditions:
a. Make sure that condenser -fan blades are correctly po-
sitioned in fan orifice. Refer to Outdoor -Fan Adjust-
ment section on page 26 for more details.
b. Make sure that air filter(s) is in place.
c. Make sure that condensate drain trap is filled with wa-
ter to ensure proper drainage.
d. Make sure that all tools and miscellaneous loose parts
have been removed.

START-UP
Unit Preparation — Make sure that unit has been in-
stalled in accordance with installation instructions and ap-
plicable codes.
Return -Air Filters — Make sure correct filters are in-
stalled in unit (see Table 1). Do not operate unit without return -
air filters.
Outdoor -Air Inlet Screens — Outdoor -air inlet screen(s)
must be in place before operating unit.
Compressor Mounting -- Compressors are inter-
nally spring mounted. Do not loosen or remove compressor
holddown bolts.
Internal Wiring — Check all electrical connections in
unit control boxes; tighten as required.
Refrigerant Service Ports — Each unit system has 3
Schrader -type service ports: one on the suction line, one on
the liquid line, and one on the compressor discharge line. Be
sure that caps on the ports are tight.
Compressor Rotation — On 3 -phase units it is im-
portant to be certain compressor is rotating in the proper di-
rection. To determine whether or not compressor is rotating
in the proper direction:
I. Connect service gages to suction and discharge pressure
fittings.
2. Energize the compressor.
3. The suction pressure should drop and the discharge pres-
sure should rise, as is normal on any start -up.
If the suction pressure does not drop and the discharge
pressure does not rise to normal levels:
1. Note that the indoor fan (006 and 007 three -phase units
only) is probably also rotating in the wrong direction.
2. Turn off power to the unit.
3. Reverse any two of the unit power leads.
4. Turn on power to the compressor.
The suction and discharge pressure levels should now move
to their normal start -up levels.
NOTE: When the compressor is rotating in the wrong di-
rection, the unit makes an elevated level of noise and does
not provide cooling.
Cooling — Set space thermostat to OFF position. Set sys-
tem selector switch at COOL position and fan switch at AUTO
position. Adjust thermostat to a setting below room tem-
perature. Compressor starts on closure of contactor.
Check cooling effects at a setting below room tempera-
ture. Check unit charge. Refer to Refrigerant Charge section
on page 26.
Reset thermostat at a position above room temperature.
Compressor will shut off.
TO SHUT OFF UNIT — Set system selector switch at OFF
position. Resetting thermostat at a position above room tem-
perature shuts unit off temporarily until space temperature
exceeds thermostat setting. Units are equipped with Cycle -
LOCT ^i protection device. Unit shuts down on any safety trip
and remains off; an indicator light on thermostat comes on.
Check reason for safety trip.
Compressor restart is accomplished by manual reset at the
thermostat by turning the selector switch to OFF position
and then to ON position.
Heating — To start unit, turn on main power supply.
Set system selector switch at I-IEAT position, and set ther-
mostat at a setting above room temperature. Set fan at AUTO
position.
First stage of thermostat energizes the indoor fan, com-
pressor, and outdoor fan; second stage energizes electric heater
elements, if installed. Check heating effects at air supply grille(s).
If electric heaters do not energize, reset limit switch
(located on indoor -fan scroll) by depressing button located
between terminals on the switch.
TO SHUT OFF UNIT — Set system selector switch at OFF
position. Resetting thermostat at a position below room tem-
perature temporarily shuts unit off until space temperature
falls below thermostat setting.
Safety Relief — A soft solder joint at the suction line
fitting provides pressure relief under abnormal temperature
and pressure conditions.
Ventilation (Continuous Fan) — Set fan and sys-
tem selector switches at ON and OFF positions, respec-
tively. Indoor fan operates continuously to provide constant
air circulation.
Operating Sequence
COOLING, UNITS WITHOUT ECONOMIZER — When
thermostat calls for cooling, terminals G and Y 1 are ener-
gized. The indoor fan contactor (iFC), compressor contactor
no. I (C 1), and outdoor fan contactor (OFC) are energized
and the indoor -fan motor, compressor, and outdoor fan start.
The outdoor -fan motor runs continuously while unit is
cooling.
HEATING, UNITS WITHOUT ECONOMIZER — Upon a
call for heating through terminal WI, IFC, OFC, and com-
pressor are energized. On units equipped for 2 stages of heat,
when additional heat is needed FiC is energized through W2.
COOLING, UNITS WiTH PARABLADE ECONOMIZER
— When the outdoor -air is above the enthalpy control set-
ting, and the room thermostat calls for cooling, the compres-
sor contactor is energized to start the compressor and the
outdoor fan motor. The indoor fan motor is energized and
the economizer damper moves to the minimum position. Af-
ter the room thermostat is satisfied the damper will spring
return to the full closed position.
When the outdoor -air is below the enthalpy control set-
ting and the thermostat calls for cooling, the economizer out-
door air damper is opened proportionally to maintain between
50 and 56 F at the mixed air sensor. If outside air alone can-
not satisfy the cooling requirements, economizer cooling is
integrated with mechanical cooling. When the room thermo-
stat is satisfied, the damper will spring return to the full closed
position.
COOLING, UNITS WITH VARISLIDE'r'^r ECONOMIZER
— When the outdoor -air temperature is above the outdoor -
air thermostat (OAT) setting and the room thermostat calls
for cooling, compressor contactor is energized to start com-
pressor and the outdoor fan motor (OFM). The indoor fan
motor (I FM) is energized and the economizer damper moves
to the minimum position. After the thermsotat is satisfied,
the indoor fan turns off. The damper then moves to the fully
closed position. When using continuous fan, the damper moves
to the minimum position.
24
When the outdoor -air Lperature is below the OAT set-
ting and the thermostat calls for cooling, the economizer damper
moves to the minimum position. If the supply -air tempera-
ture is above 57 F, the damper continues to open until it reaches
the fully open position or until the supply -air temperature
drops below 52 F.
When the supply -air temperature falls between 57 F and
52 F, the damper will remain at an intermediate open posi-
tion. If the supply -air temperature falls below 52 F, the damper
will modulate closed until it reaches the minimum position
or until the supply -air temperature is above 52 F. When the
thermostat is satisfied, the damper moves to the fully closed
position when using AUTO. fan or to the minimum position
when using continuous fan.
if the outdoor air alone cannot satisfy the cooling require-
ments of the conditioned space, economizer cooling is in-
tegrated with mechanical cooling, providing 2 stages of cooling.
Compressor and the outdoor fan will be energized and the
position of the economizer damper will be determined by
the supply -air temperature. When the second stage of cool-
ing is satisfied, the compressor and OFM will be deener-
gized. The damper position will be determined by the supply -
air temperature. When the first stage of cooling is satisfied,
there is a 30- second delay before the evaporator fan shuts
off. The damper then moves to the fully closed position. When
using a continuous fan, the damper moves to the minimum
posit ion.
HEATING, UNITS WITH ECONOMIZER — Upon a call
for heat through W I, the IFC energizes to start the evapo-
rator fan and the economizer damper blade opens to the mini-
mum position. If the accessory two - position damper is used,
the outdoor -air damper opens to the minimum position when-
ever the evaporator fan runs. If unit is equipped with 2 stages
of heat, when additional heat is needed a call is made through
W2.
As space temperature approaches the heating temperature
set point, heating stages cycle oft. Economizer or two -
position damper returns to fully closed position.
DEFROST —As frost builds up on the outdoor coil, the coil
temperature drops below 28 F. When this outdoor -coil tem-
perature drop is sensed by the defrost thermostat (DFT) and
the defrost timer is at the end of a timed period (adjustable
at 30, 50, or 90 minutes), the unit operates in a defrost cycle
controlled by the defrost timer and thermostat. During this
cycle, the reversing valve solenoid (RVS) is energized and
the outdoor fan shuts off'. The electric heaters (if installed)
will be energized.
The unit continues to defrost until the coil temperature as
measured by DFT reaches 65 F, or the duration of defrost
cycle completes a 10- minute period.
At the end of the defrost cycle, the electric heaters (if in-
stalled) and the reversing valve will be deenergized, and the
outdoor -fan motor will be energized. The unit will now op-
erate in the heating mode.
If the thermostat is satisfied during a defrost cycle, the
unit will continue in the defrost mode until the time or tem-
perature constraints are satisfied.

Refrigerant Charge"* Amount of refrigerant charge
is listed on unit nameplate (also refer to Table 1). Refer to
Carrier Refrigerant Service Techniques Manual, Refriger-
ants section.
Unit panels must be in place when unit is operating dur-
ing charging procedure.
NO CHARGE — Refer to Carrier Refrigerant Service Tech-
niques. Use standard evacuating techniques. After evacuat-
ing system, weigh in the specified amount of refrigerant. (Refer
to Table 1.)
LOW CHARGE COOLING — Use Cooling Charging Charts,
Fig. 30 -33. Vary refrigerant until the conditions of the charts
are met. Note that the charging charts are different from type
normally used. Charts are based on charging the units to the
correct superheat for the various operating conditions. Ac-
curate pressure gage and temperature sensing device are re-
quired. Connect the pressure gage to the service port on the
suction line. Mount the temperature sensing device on the
suction line and insulate it so that outdoor ambient tempera-
ture does not affect the reading. Indoor -air cfm must be within
the normal operating range of the unit.
TO USE COOLING CHARGING CHARTS —Take the out-
door ambient temperature and read the suction pressure gage.
Refer to charts to determine what the suction temperature
should be. If suction temperature is high, add refrigerant. If
suction temperature is low, carefully recover some of the charge.
Recheck the suction pressure as charge is adjusted.
Example: (Fig. 30)
Outdoor Temperature 85 F
Suction Pressure 74 psig
Suction Temperature should he 52 F
(Suction Temperature may vary ± 5° F.)
If Chargemaster® charging device is used, temperature and
pressure readings must be accomplished using the charging
charts.

1. Disconnect power at TR and TR1. Disconnect jumper across P and P1.
2. Connect jumper across TR and 1.
3. Connect jumper across T1 and T.
4. If connected, remove enthalpy sensor from terminals S and +. Factory-
installed 620 ohm resistor should be connected to terminals S and +.
5. Apply power (24 Vac) to terminals TR and TR1. The LED should be off
and the damper should be in the closed position.
6. Disconnect the factory - installed 620 ohm resistor from terminals SR and
+. The LED should light up and the motor should drive towards open. If
this does not happen, replace the economizer control module.
Return spring failure.
If power to unit is off and damper does not close, check for a bound linkage.
If linkage is not bound, then internal spring may be broken. Replace
actuator.
Economizer motor failure.
If the economizer control module is functioning properly, verify that there is a
minimum of 24 Vac at terminals TR and TR1. If the motor is not operating,
replace the motor.
Damper does not open
or close according to
enthalpy readings.
Sensor incorrectly wired or bad.
To verify sensor operation, reconnect the + lead of the outdoor enthalpy sen-
sor to the + terminal of the economizer control module. Connect a DC mil -
liammeter between terminals So of the economizer control module and
terminals S of the enthalpy sensor. The milliammeter should indicate be-
tween 3 and 25 mA if the sensor is operating properly. If the milliammeter
indicates 0, the sensor may be wired backwards. If any other readings are
shown, replace the sensor.

reduction of greenhouse
gases expelled from indus-
trial processes.
Form 5OHJQ -1 PD
Carrier means Top Quality
and Reliability
Each component utilized in the
Weathermaster® Series is designed
and tested for a minimum of 15 years
operation under the harshest
conditions.
Every unit is thoroughly run tested
at the factory in each operating mode
and evacuated prior to final charg-
ing. Every coil is then leak- tested with
helium. Automated run testing al-
lows accurate undisputed tests and
measurements which are second to
none in the industry.
Each unit contains a factory print-
out indicating tested pressures, amper-
ages, dates, and inspectors, providing
certification of the unit's status at
the time of manufacture.
Units are equipped with valuable
safety controls designed to moni-
tor and protect the unit for life. The
standard safeties include:
• low - pressure/loss -of- charge switch
• high - pressure switch
• freeze - protection thermostat
• internal compressor overload
• exclusive Carrier Cycle -LOCTM cir-
cuit board that provides anti -
compressor cycling
• refrigerant filter drier
The cabinet is constructed of galva-
nized steel, bonderized and coated
with a prepainted baked enamel fin-
ish. The paint finish is a non - chalking
type, and is capable of withstanding
Federal test Method Standard No.
141 (Method 6061) 500 -hour salt
spray test. In addition, all internal
cabinet panels are primed, allowing
the entire unit to have a longer life
and more attractive appearance.
2
Easy maintenance and
installation
All units are factory shipped in
the vertical discharge configura-
tion for fit -up to standard roof curbs.
(One accessory curb fits sizes 004-
007; another accessory curb fits sizes
008 -012.) The contractor can order
and install the roof curbs early in
the construction stage, before deci-
sions on size requirements have been
made.
All units feature heavy -gage roll -
formed baserail design with fork'
lift slots on 3 sides of the unit and
rigging holes for easier maneuvering
and installation. Stretch -wrap packag-
ing protects the unit during ship-
ment and storage.
Units are easily converted from
vertical to horizontal applications
or any other combination to make ret-
rofit and add -on jobs easier. To con-
vert from vertical to horizontal
discharge, simply move 2 panels. The
same basic unit can be used for a
variety of applications and can be
quickly modified at the jobsite. Stand-
ard high- static, high - performance,
Table of contents

belt driven indoor fan motors enable
5OHJQ004 -012 units to success-
fully operate in any ductwork
configurations.
Ductwork connections are simpli-
fied by the logical 2 to 1 aspect ra-
tio. On vertical discharge units,
ductwork attaches directly to the roof
curb.
Thru - the - bottom service connec-
tion capability allows power and
control wiring to be routed through
the unit basepan, thereby minimizing
roof penetrations and lowering the
risk of leaks.
The non - corrosive, sloped, con-
densate drain pan is factory installed
and in conformance with ASHRAE
(American Society of Heating, Refrig-
eration, and Air Conditioning Engi-
neers) Standard 62 to meet many
Indoor -Air Quality (IAQ) specifications.
The condensate drain pan offers
both bottom and end drain capabili-
tyto minimize roof penetrations. The
bottom drain can be used in con-
junction with the thru- the -bottom con-
nections. An external trap must be
field supplied.

Features /Benefits ‘cont)
Standard 2 -in, throwaway filters are
easily accessed through a removable fil-
ter access panel located directly above
the air intake hood; no tools are re-
quired to change the filters.
All units are designed with a
single continuous top piece to elimi-
nate any possible leaking at the seams
or gasketing, which tends to deteriorate
over time and shift during rigging
procedures.
Belt -driven indoor -fan motors on all
sizes allow maximum on -site flexibility
without changing motors or drive speeds.
Low - voltage wiring connections are
easily made due to the terminal board
which is conveniently located for quick
simple access.
Single -point electrical power
connections permit easier wire
estimating and connections.
Field - installed accessory electric
heaters are available in a wide range
of capacities. Single -point wiring kit makes
installation simple.
NOTE: Not all electric heater applica-
tions are available with the factory -
installed disconnect switch.
Quiet, efficient operation and
dependable performance
All units are equipped with scroll
compressors that are fully her-
metic with internal vibration isolators
for extremely quiet and highly efficient
operation. Compressors are mounted
on independent composite mount-
ing plates for additional sound integ-
rity and structural support. Efficient
outdoor fan and motor design permits
operation at a low sound power of
7.6 bels for sizes 004 and 005,
8.0 bels for size 006 and 007,
8.2 bels for size 008 and 8.4 bels
for size 012.
Totally enclosed outdoor fan mo-
tors and permanently lubri-
cated bearings provide additional
dependability.
All coils use state -of- the -art inter-
nally enhanced copper tubing.
Coils are thoroughly leak and pressure
tested at the factory. Outdoor coils
have louvered, aluminum lanced fins
to provide maximum heat transfer
for optimum efficiency and easy
cleaning.
4
Refrigerant circuit protection
ensures dependability. All units have
standard:
1) loss -of- charge/low- pressure protec-
tion switch which allows operation
at lower ambient conditions while
protecting against low- charge
operation
2) freeze - protection thermostat, which
protects against indoor coil frost
build -up
3) high- pressure switch, which pro-
tects against above normal oper-
ating pressure
4) filter driers, which trap moisture
and debris in the refrigeration
system
5) Carrier's exclusive Acutrolm meter-
ing device, which precisely controls
refrigerant flow, preventing slug-
ging and floodback, while maintain-
ing optimum unit performance by
metering the circuits individually.
Two independent compressor cir-
cuits (71/2 and 10 ton units) provide
pinpoint comfort control, improved
operating efficiency, and back -up
capability.
Patented ChronotempTM defrost
system uses time and temperature to
keep the outdoor coil frost -free for
economical, dependable operation.
The Chronotemp defrost board can
easily be configured for defrost cycles
every 30, 50, or 90 minutes.
Patented Cycle -LOCTM protection
system provides protection against
compressor cycling by monitoring
compressor current. When a lack of
compressor current exists, the
Cycle -LOC circuit board locks out the
compressors. Cycle -LOC may be
manually reset by simply switching the
thermostat to OFF, and back to the
Heating, Cooling or AUTO modes.
No use of the unit power discon-
nect is required.
Carrier controls add
reliability, efficiency,
and simplification
Apollo communicating controls
can be ordered as a factory- installed
option. Designed and manufactured
exclusively by Carrier, the controls can
be used to actively monitor all modes
of operation as well as indoor fan
status, filter status, indoor -air quality,
supply -air temperature, and outdoor -air
temperature.
The Apollo control board is factory -
installed in the rooftop unit control
box and comes equipped with built -in
diagnostic capabilities. Light - emitting
diodes (LEDs) simplify troubleshooting
by indicating thermostat commands
for both stages of heating and cooling,
indoor (evaporator) fan operation,
and economizer operation. The Apollo
communicating control is designed to
work specifically with Carrier TEMP
and VVT® thermostats.
The standard control system is
readily adaptable to all conventional
and programmable thermostats. In
addition, units are suitable for integra-
tion into building monitor control
systems if required.
Indoor air quality
The Weathermastere series utilizes
certain key features that assist in
improving the quality of the building
air. Sloped condensate pans eliminate
possible biological growth in the
rooftop unit. A face -split indoor coil
design proves effective in additional
moisture removal from the supply air
on the 71/2 to 10 ton sizes during
single stage cooling operation.
Two -in. filters are standard in all
rooftop units with an optional filter
status sensor available. Enthalpy con-
trol is standard on the PARABLADE
economizer.
Serviceability
Standardized components for the
complete Weathermaster line of
products are found in all safety de-
vices, outdoor -fan motors, and control
boards. This allows for greater in-
ventory control, familiarity, and fewer
stocked parts.
Easily accessible refrigerant ac-
cess ports on all discharge, suction,
and liquid lines permit easy and ac-
curate measurements.
Resettable 24 -v circuit breaker
allows room for error without replac-
ing transformers or fuses.
Single -side utility connections
provide easy access to perform any
necessary service.
Color -coded wires permit easy trac-
ing and diagnostics.
Belt- driven motors are accessible
through a single access door to facili-
tate servicing and adjusting after
installation.
Compressors and safety switches
are easily accessible for trouble -
shootn; and system analysis.

Exclusive Durablade economizer damper design saves energy while provid-
In9 economical and reliable cooling. A sliding plate on the face of the econo-
mizer controls the amount of outdoor air entering the system. When the sliding
plate is closed, it provides a leakproof seal which prevents ambient air from
seeping in or conditioned air from seeping out. It can be easily adjusted for
100% outdoor air or any proportions of mixed air. The Durablade economizer
has a 30% barometric relief capacity and features close on power loss.
FACTORY - INSTALLED APOLLO COMMUNICATING
CONTROLS
The Apollo direct digital controls are designed exclusively by Carrier, and are
used to actively monitor and control all modes of operation as well as to moni-
tor evaporator -fan status, filter status, supply -air temperature, outdoor -air tem-
perature, and indoor -air quality. They are designed to work in conjunction with
Carrier TEMP and VVTA system thermostats.
COIL GRILLE
Coil Grille protects coils against large objects and vandalism.

Factory - installed PARABLADE economizer features a new reliable design. The
economizer utilizes parallel opposed -blade dampers, a motor with built -in spring
return for close upon power loss, standard enthalpy controls, and 30% (004-
007) or 45% (008,012) barometric capability for added flexibility in high outdoor -
air applications.
TIME GUARDS II CONTROL
Time Guard II Control (standard on single-phase units) automatically prevents
compressor from restarting for at least 5 minutes after a shutdown. Accessory
prevents short cycling of compressor If thermostat Is rapidly changed. Time
Guard II device mounts In the control compartment of unit.

ACCUSENSORTM II
ACCUSENSOR III
Accusensor economizer controls help provide efficient, economical
economizer operation. The standard Accusensor I dry-bulb sensor
measures outdoor temperature. Accusensor II solid -state enthalpy
control senses both dry and wet bulb of the outdoor air to provide an
accurate enthalpy reading. Accusensor III differential enthalpy sen-
sor compares outdoor temperature and humidity to return -air tem-
perature and humidity and determines the most economical mixture
of air. Accusensor II is standard on PARABLADE economizer.

Selection procedure (with 50HJ0005 example)
I Determine cooling and heating requirements at
design conditions:
Given:
Required Cooling Capacity (TC) 38,000 Btuh
Sensible Heat Capacity (SHC) 24,000 Btuh
Required Heating Capacity 35,000 Btuh
Outdoor Entering -Air Temperature 95 F
Outdoor -Air Winter Design Temperature 0° F
Indoor -Air Winter Design Temperature 70 F
Indoor Entering -Air
Temperature .... 80 F edb (entering air, dry bulb),
67 F ewb (entering air, wet bulb)
Indoor -Air Quantity 1600 cfm
External Static Pressure 0.45 in. wg
Electrical Characteristics (V- Ph -Hz) 230 -3 -60
H Select unit based on required cooling capacity.
Enter Cooling Capacities table at outdoor entering tem-
perature of 95 F, indoor air entering at 1600 cfm and
67 F ewb. The 50HJ0005 unit will provide a total cool-
ing capacity of 47,400 Btuh and a sensible heat ca-
pacity of 32,800 Btuh.
For indoor -air temperature other than 80 F edb, cal-
culate sensible heat capacity correction, as required,
using the formula found in Note 2 following the cool-
ing capacities tables.
NOTE: Unit ratings are gross capacities and do not in-
clude the effect of indoor -fan motor heat. To calculate
net capacities, see Step V.
III Select electric heat.
Enter the Instantaneous and Integrated Heating Rat-
ings table at 1600 cfm. At 70 F return indoor air and
0° F air entering outdoor coil, the integrated heating
capacity is 20,400 Btuh. (Select integrated heating ca-
pacity value since deductions for outdoor -coil frost and
defrosting have already been made. No correction is
required.)
The required heating capacity is 35,000 Btuh. There-
fore, 14,600 Btuh (35,000 — 20,400) additional elec-
tric heat is required.
Determine additional electric heat capacity in kW.
14,600 Btuh = 4.3 kW of heat required.
3413 Btuh/kW
Enter the Electric Heating Capacities table for 5OHJQ005
at 208/230, 3 phase. The 6.5 -kW heater at 240 v
most closely satisfies the heating required. To calculate
kW at 230 v, use the Multiplication Factors table.
6.5 kWx.92 = 5.98 kW
6.5 kW x .92 x 3413 = 20,410 Btuh
Total unit heating capacity is 40,810 Btuh (20,400 +
20,410).
IV Determine fan speed and power requirements
at design conditions.
Before entering Fan Performance tables, calculate the
total static pressure required based on unit compo-
nents. From the given and the Pressure Drop tables,
find:
External static pressure .45 in. wg
Durablade economizer .05 in, wg
Electric heat .09 in. wg
Total static pressure .59 in. wg
Enter the Fan Performance table for 50HJ0005 ver-
tical discharge. At 1600 cfm and 230 -v, the standard
motor will deliver 1.2 in. wg static pressure and 1.15
brake horsepower (bhp). This will adequately handle
job requirements.
NOTE: Convert bhp to Watts using the formula found
in the note following the Indoor -Fan Motor Efficiency
table.
For this example:
Watts — 746 x Bhp
Motor Efficiency
Watts — 746 x 1.15
.75
Watts = 1144
V Determine net capacities.
Capacities are gross and do not include the effect of
indoor -fan motor (IFM) heat.
Determine net cooling capacity as follows:
Net capacity = Total capacity — 1FM heat
= 47,400 Btuh — (1144 Watts x 3.413
Btuh/Watts)
= 47,400 Btuh — 3904 Btuh
= 43,496
Net sensible capacity = 32,800 Btuh — 3904 Btuh
= 28,896 Btuh
Integrated heating capacity is maximum (instantaneous)
capacity less the effect of frost on the outdoor coil and
the heat required to defrost it. Therefore, net capacity
is equal to 40,810 Btuh, the total heating capacity de-
termined in Step Ill.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
tldb ° (edb ' sensible capacity (Bluh)
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving evaporator coil (lrlwb)
total capacity (Btuh)
hlwb = hewb - 4.5 x cfm
Where: hewb = Enthalpy of air entering evaporator coil
3. The SHC is based on 80 F edb temperature of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 - BF) x (edb - 80).

'Used to determine minimum disconnect per NEC.
tHeater capacity (kW) is based on heater voltage of 208 v, 240 v, and 480 v. If
power distribution voltage to unit varies from rated heater voltage, heater kW
will vary accordingly.
"Fuse or HACR circuit breaker.
ttOptional disconnect switch cannot be used.
II Units have 2 outdoor fan motors.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load and
equipment (refer to NEC Articles 430 and 440), the overcurrent protective de-
vice for the unit shall be fuse or HACR breaker.
2. Unbalanced 3 -Phase Supply Voltage
Never operate a motor where a phase imbalance In supply voltage Is greater
than 2 %. Use the following formula to determine the percentage of voltage im-
balance.
36
% Voltage Imbalance
100 x max voltage deviation from average voltage
average voltage
Example: Supply voltage is 460-3-60
AB = 452 v
BC = 464 v
AC = 455 v
Average Voltage =
A B
C
452 + 464 + 455
3
1371
3
= 457
Determine maximum deviation from average voltage:
(AB) 457 - 452 = 5 v
BC 464 -457= 7v
AC 457 - 455 = 2 v
Maximum deviation is 7 v.
Determine percentage of voltage imbalance:
% Voltage imbalance = 100 x
457
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2 %.
IMPORTANT: If the supply voltage phase Imbalance is more than 2% con-
tact your local electric utility company Immediately,

Used to determine minimum disconnect per NEC.
tHeater capacity (kW) is based on heater voltage of 208 v, 240 v, and 480 v. If
power distribution voltage to unit varies from rated heater voltage, heater kW
will vary accordingly.
"Fuse or HACR circuit breaker.
tiOptional disconnect switch cannot be used.
Ill Units have 2 outdoor fan motors.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load and
equipment (refer to NEC Articles 430 and 440), the overcurrent protective de-
vice for the unit shall be fuse or HACR breaker.
2. Unbalanced 3 -Phase Supply Voltage
Never operate a motor where a phase Imbalance in supply voltage is greater
than 2 %. Use the following formula to determine the percentage of voltage im-
balance.
38
% Voltage Imbalance
= 100 x max voltage deviation from average voltage
average voltage
Example: Supply voltage is 460-3-60
AB = 452 v
BC = 464 v
AC = 455 v
Average Voltage =
A B C
452 + 464 + 455
3
1371
3
= 457
Determine maximum deviation from average voltage:
AB 457 - 452 = 5 v
BC 464 - 457 = 7 v
AC 457 - 455 = 2 v
Maximum deviation is 7 v.
Determine percentage of voltage imbalance:
% Voltage imbalance = 100 x 457
= 1.53%
This amount of phase imbalance is satisfactory as It is below the maximum
allowable 2 %.
IMPORTANT: If the supply voltage phase imbalance is more than 2% con-
tact your local electric utility company immediately.

Operating sequence — 5OHJQ004 -007 units
Cooling, units without economizer — When the ther-
mostat calls for cooling, terminals G and Y1 are energized.
The reversing valve solenoid (RVS), indoor -fan contactor
(IFC), and compressor contactor no. 1 (C1) are energized
and the indoor -fan motor (IFM), compressor, and outdoor
fan start. The outdoor -fan motor (OFM) runs continuously
while unit is cooling.
Cooling, units with Durablade economizer — When
the outdoor -air temperature is above the OAT (outdoor -air
temperature) setting and the room thermostat calls for cool-
ing, the reversing valve solenoid (RVS) and the compressor
contactor are energized to start the compressor and outdoor -
fan motor (OFM). The indoor -fan motor (IFM) is energized
and the economizer damper moves to the minimum posi-
tion. After the thermostat is satisfied, the damper moves to
the fully closed position when IFM is deenergized.
When the outdoor -air temperature is below the OAT set-
ting and the thermostat calls for Y1 and G (cooling), the
economizer damper moves to the minimum position when
the indoor fan starts. The first stage of cooling is provided
by the economizer. If the supply -air temperature is above
57 F, a switch on the supply -air thermostat is closed be-
tween the T2 terminal and the 24 vac terminal. This causes
the•damper to continue to modulate open until the supply -
air temperature falls below 55 F or the damper reaches the
fully open position.
When the supply -air temperature is between 55 F and
52 F, the supply -air thermostat has open switches between
the T2 and 24 vac terminals and between the T1 and
24 vac terminals. This causes the economizer damper to
remain in an intermediate open position.
If the supply -air temperature falls below 52 F, a switch
on the supply -air thermostat is closed between the T1 ter-
minal and the 24 vac terminal. This causes the damper to
modulate closed until the supply -air temperature rises above
55 F or the damper reaches the minimum position.
When the supply -air temperature is between 55 F and
57 F, the supply -air thermostat has open switches between
the T2 and 24 vac terminals. This causes the economizer
damper to remain in an intermediate open position.
If the outdoor air alone cannot satisfy the cooling require-
ments of the conditioned space, economizer cooling is in-
tegrated with mechanical cooling, providing second stage
cooling. The compressor and outdoor fan will be energized
and the position of the economizer damper will be deter-
mined by the supply -air temperature.
40
When the second stage of cooling is satisfied, the com-
pressor and OFM will be deenergized. The damper posi-
tion will be determined by the supply -air temperature.
When the first stage of cooling is satisfied, the indoor fan
shuts off. The damper will move to fully closed position.
Cooling, units with PARABLADE economizer — When
the outdoor air is above the enthalpy control setting, and
the room thermostat calls for cooling, the compressor con-
tactor is energized to start the compressor and the outdoor -
fan motor. The indoor -fan motor is energized and the econo-
mizer damper moves to the minimum position. After the
room thermostat is satisfied the damper will spring return
to the fully closed position.
When the outdoor air is below the enthalpy control set-
ting and the thermostat calls for cooling, the economizer
outdoor air damper is opened proportionally to maintain
between 50 and 56 F at the mixed air sensor. If outside air
alone cannot satisfy the cooling requirements, economizer
cooling is integrated with mechanical cooling. When the
room thermostat Is satisfied, the damper will spring return
to the fully closed position.
Heating, units without economizer — Set system switch
at AUTO. or HEAT position. Set thermostat at desired
temperature.
When the thermostat calls for heat, the IFC, outdoor -fan
contactor and compressor contactor are energized. The re-
versing valve solenoid (RVS) is deenergized and switches
position, and the indoor fan, outdoor fan, and compressor
are energized. On economizer units, the economizer blade
will move into the minimum position.
If the thermostat calls for a second stage of heat, the heater
contactor (HC1) is energized and starts the electric heaters.
When the space temperature approaches the heating tem-
perature set point, heating stages cycle off. The RVS is
reenergized.
Heating, units with economizer — When the room tem-
perature calls for heat through terminal W1, the indoor fan
contactor and heater contactor no. 1 are energized. On units
equipped for 2 stages of heat, when additional heat is needed,
heater contactor no. 2 is energized through W2. The econo-
mizer damper moves to the minimum position. When the
thermostat is satisfied, the damper moves to the fully closed
position.

Controls (cant) C
Heating, units with economizer When the room ther-
mostat calls for heat through terminal W1, the Indoor fan
contactor and heater contactor no. 1 are energized, On units
equipped for 2 stages of heat, when additional heat is needed,
heater contactor no. 2 is energized through W2. The econo-
mizer damper moves to the minimum position, When the
thermostat is satisfied, the damper moves to the fully closed
position.
Defrost -- When the temperature of the outdoor coil drops
below 28 F as sensed by the defrost thermostat (DFT2) and
the defrost timer is at the end of a timed period (adjustable
at 30, 50, or 90 minutes), reversing valve solenoids (RVS1
and RVS2) are energized and the OFC is deenergized. This
switches the position of the reversing valves and shuts off
the outdoor fan. The electric heaters (if installed) will be
energized.
The unit continues to defrost until the coil temperature
as measured by Di'I'2 reaches 65 F, or the duration of de-
frost cycle completes a 10- minute period.
During the defrost mode, If circuit 1 defrosts first, RVS1
will oscillate between heating and cooling modes until the
defrost mode is complete.
At the end of the defrost cycle, the electric heaters (if in-
stalled) will be deenergized; the reversing valves switch and
the outdoor -fan motor will be energized. The unit will now
operate in the heating mode.
If the space thermostat is satisfied during a defrost cycle,
the unit will continue in the defrost mode until the time or
temperature constraints are satisfied.

TEMP Systems
A TEMP System is a network of communicating Carrier
TEMP System Thermostats and factory - installed Apollo com-
municating controls, each serving Its own zone and heating/
cooling unit. Networking allows your building manager to
easily access each of your systems from a single location...
whether they are in the same building or located through-
out town.
The TEMP System's inherently flexible, modular base de-
sign supports the exact number of independent, single zone
systems you require...no more, no less, no compromises.
ideal for department stores, small office buildings, fast
food chains, schools, and hotels, a TEMP System is a
cost - effective way to maintain comfortable building
environments.
Variable Volume/Variable Temperature
(VVT') Systems
VVT Systems are dedicated to total building comfort.
Carrier thermostats, zone dampers, HVAC equipment, and
field- Installed Apollo communicating controls continually
monitor and adjust their operation to ensure uninterrupted
and personalized comfort for all occupants.
Through the use of communicating electronic controls,
VVT Systems are able to provide the comfort of a multiple
zone system while using the installation, operation, and main-
tenance economics of single zone equipment. ..virtually
putting an end to the cost vs. comfort compromise.
