Replacement roof mounted packaged air conditioning units manufactured by SEASONS -4
with dimensions, capacities and electrical characteristics as shown in this submittal will be
provided. Seasons -4 has been manufacturing equipment of this type for over 10 years. The
equipment complies with the requirements and terms of ETL's Listing, Labeling and Follow -
up Service Agreement and the complete unit bears the ETL Label.
In order to provide improved reliability, higher efficiency, and meet requirements for
improved rates of ventilation, the new units may be slightly higher, longer, or wider than the
units being replaced; however; the base of the new unit is designed to match the existing curb
and duct connections of the unit being replaced. Prior to Seasons -4's engineer completing the
design of the unit, a technician visited the project, measured the old unit's ducts, determined
the location of the utilities, and noted any obstructions adjacent to the unit.
EXTERIOR CASING AND FRAME
The unit base will be constructed of formed, heavy gauge galvanized structural steel. Lifting
lugs are welded on the base frame for rigging the unit. All exterior panels are fabricated
from Series 3003 pre - painted aluminum, color to be determined. Aluminum panels are
fastened to the frame with stainless steel bolts. Panels are isolated from the steel base with
dielectric gaskets to prevent galvanic corrosion. The roof of the unit is pitched to provide
positive drainage. Top seams are covered with cap strips to prevent water leakage into the
unit and the floor of each section has a galvanized steel deck to isolate the entire unit from
the building. All seams are caulked with silicone inside and out to prevent air and water
leakage.
Access doors are provided for all sections housing components requiring routine
maintenance. Doors are supported on full- length continuous aluminum hinges and have
Ventlok Series 260 latches. Full height access doors have stainless steel "hold back" latches
to prevent door closure during the performance of service procedures.
All walls, roof, and doors in the air - handling compartment and the air - cooled condenser are
double wall construction enclosing 2" thick fiberglass insulation. Liners are aluminum
sheetmetal to protect the insulation during routine service and maintenance operations. The
floor of the air handling sections is insulated with 1" foil faced fiberglass.

Compressors
The unit is equipped with scroll compressors. The compressors will stage based on discharge air
temperature. Cooling will be enabled by the space sensor and staged based on discharge air
temperature. When the coil LAT is above the discharge setpoint, the compressors will stage on at
intervals of three minutes until the LAT is at or below the discharge setpoint. If the LAT is below
the discharge setpoint for three minutes, one stage will de- energize. This process will continue
until all stages are de- energized. The evaporator leaving air temperature setpoint is 55° F.
Capacity control will be achieved by staging compressors. Each stage of the compressor
sequencing will run for a minimum of 3 minutes once it is called. Each compressor will have an
on -delay of 5 minutes.

RECEIVING AND INSTALLATION INSTRUCTIONS
Seasons 4 roof mounted air conditioners are designed and catalogued with standard features as shown on
specification material. However, these units are often furnished to meet special engineering requirements, and
some units have special components. In such cases, installation and startup procedures will vary slightly
depending upon the special feature. It is recommended that a factory engineer be consulted in each special
situation.
Experience has proven that proper and thorough Start- test - adjustment procedures completed upon installation
provide the customer or user maximum satisfaction and the installation contractor less expense during the life of
the equipment.
CODES AND INSTALLATION REQUIREMENTS
Local codes and regulations must necessarily supercede all recommendations made by the factory and
appropriate authorities should be consulted before installation. Where an apparent conflict of code requirements
and manufacturer recommendations or standard design exists, the assistance of a sales engineer should be
requested. In almost every instance, the factory will be able to make the necessary modifications to comply with
local codes and interpretations, if notified prior to actual fabrication or upon order placement.
RECEIVING THE EQUIPMENT
Before acceptance of the equipment upon its arrival at the job site, the equipment should be inspected
CAREFULLY for damage that may have occurred during shipment. If physical damage is observed, it should be
noted and itemized on the carrier's freight bill. The manufacturer must be notified in writing so that appropriate
action may be taken. It is VERY IMPORTANT that all items shown on the manufacturer's Packing Slip be
checked to verify the quantity and description of each item before signing the manufacturer's copy. Should any
items be found missing or should there be a conflict between items received and those shown on the packing
slip, it should be noted on the manufacturer's copy and on the carrier's freight bill.
Items appearing on manufacturer's packing list which should be checked to verify receipt of correct quantity:
• Air conditioning units
• Remote mounted sensors or thermostats packed in a separate carton, or sometimes mounted in
unit
• Extra filters, separately boxed
• Electrical accessories, time switches, central control panels, etcetera, separately boxed
Although the design of the unit roof mounting supports is usually done by an architect or structural engineer, it is
coordinated with dimensional data supplied by the manufacturer. Recommended mounting details and
dimensions which the mechanical contractor may use for verification of correct steel roof curb dimensions and
electrical and gas service locations on the job site before the arrival of the equipment are furnished by Seasons
4, Inc. If this Is done, time and money may be saved when the equipment arrives. If any details are found to be
questionable, consult with the local Unit Manufacturer's Representative or the factory.

PLACING THE EQUIPMENT
ii
z •
SEASOf1S•4
When the equipment arrives, the air conditioning units are chained to a flat bed trailer. Coordinated arrival of the
equipment and the crane should have previously been arranged with the factory. This is necessary if extra
unloading costs are to be avoided. The truck driver will unchain the units. NOTE: It is the responsibility of the
contractor to provide the necessary personnel to unload and rig the equipment to the roof and the manufacturer
will assume NO additional costs incurred by the failure of the contractor to meet this responsibility.
Units which are mounted on a roof curb (usually provided by the unit manufacturer) must utilize a curb gasketing
material. The curb gasket acts as a moisture and weather seal between the unit and the roof curb. Seasons 4
ships an ample supply of curb gasket inside the unit. A label on the unit will identify exactly where in the unit the
gasket may be found. It is the responsibility of the contractor to install the curb gasket. The curb gasket should
be installed around the perimeter of the curb and any duct opening cross members. • -
Each unit is provided.with lifting brackets welded to the unit base frame for the purposg_of attaching lifting hooks
(see drawing). It is the responsibility of the crane operator to provide and utilize adjustable cable spreader bars.
The spreader bars must be placed as close to the top of the unit as possible. The spreader bars must also be
wider than the unit so that the cable will angle away from the unit. This will prevent damage to the cabinet.
Seasons 4 Inc. will not be responsible for damage to the equipment due to improper rigging procedures.
Drawing depicts recommended spreader bar configuration. Actual number of lifting lugs may vary. Consult
factory.

SEASONS -4 UNIT START UP POLICY
Before start is done, there are several items that must be completed by the installing contractor. These
items are as follows:
1) All power and control wiring complete
2) Gas lines complete and purged
3) All sensors installed and terminated in control panel
4) Main power to the unit connected
5) All duct main runs completed
6) All unit control switches "off'
7) Main power on for 12 hours before start-up
8) All items shipped loose installed (O.A. hood, vent caps, drain traps, etc.)
9) All shipping block removed from blower and compressors (if spring mounted)
At start up, the contractor on record is to have the personnel responsible for the operation of the equipment
present. This person is to have all the required gauges, test equipment and tools required to start the unit.
The Seasons -4 technician will supervise the start-up and provide instructions in the operation of the
equipment, as well as point out areas of particular design and maintenance requirements. All work will be
done by the contractor's representative. If problems are found at start they will be corrected at that
time by Seasons -4's technician and the contractor representative. Labor and parts required to correct the
problem will be handled on the spot by our technician and /or the Atlanta office.
For further information, contact Gary Hulsey, or John Kodobocz, at the following:
Seasons -4, Incorporated
4500 Industrial Access Road
Douglasville, GA 30134
Phone: (770) 489 -0716
Fax: (770) 489 - 2938
Seasons -4 will provide a factory authorized technician to supervise and instruct in the start -up of all units.
The start -up should be requested a minimum of two weeks (10 working days) before the actual date of the
start -up. Seasons -4 will contact the person requesting start -up to confirm a start -up date.
When the start-up is completed, both parties will sign the unit acceptance of start -up. One copy will be
given to the contractor representative, and one copy will be sent to the customer as proof of start -up.
In the cost of start -up, only one trip to the jobsite will be allowed. Seasons -4 will not return to start the unit
for A/C or heating at another time. If more than one trip is necessary, approval from both the customer and
Seansons -4 is mandatory as additional fees may be required, and will require a Purchase Order number to
be issued.
If problems are found after the unit, start-up, they will be handled under our unit warranty. All repairs
under warranty must be approved by Seasons -4, and a field claim number assigned. These invoices will be
returned to sender.

RIGGING INFORMATION & INSTRUCTIONS
SEASONS•4 RES PRODUCTS
Seasons•4 manufactures RES Series roof mounted HVAC units designed to replace most
units ever built. In addition to a replacement expert having measured the existing units to
provide our engineers with the information they need to design the unit, additional
rigging assistance is also provided. The following instructions are intended to describe
this service and to assist our customers with the installation of their units.
RIGGING ASSISTANCE
1. Seasons•4 provides an experienced person to be on site with the installer during
rigging. When the "on site" date approaches, we make arrangements for a person
experienced in installing replacement equipment to be at the jobsite when the
units arrive.
2. In the interest of maintaining good customer relationships and addressing any
unforeseen problems (old units weren't always installed in accordance with their
manufacturer's recommendations), our Seasons -4 Representatives usually plan to
be at the jobsite.
3. "RIGGING ASSISTANCE" includes advice on rigging (see below),
recommendations for solving unexpected problems uncovered when the old unit
is removed, and offering advice on the proper location of the new unit on the
existing curb.
4. Note! Seasons•4 personnel are not responsible for the rigging; they merely offer
advice. The installing contractor or owner and their rigger are responsible for
properly rigging the units. The riggers are the experts and must know the
capabilities of their equipment and the proper procedures for placing the units in
the proper location.
SAFETY
It is imperative for the installing contractor to instruct all personnel attending the rigging
in proper safety procedures:
1. Under no circumstances shall any person stand below a unit being lifted or
removed. Be aware of loose pieces that may fall from the old units.
2. Where it becomes necessary to reach under a unit to remove attached ductwork,
see below in the section on duct attachments.
3. If for any reason a person is required to place hands or arms under a lifted unit
supported by the crane, the contractor shall insert wood blocks across each corner
of the curb. Blocks shall be of sufficient height, length and strength to maintain
the unit above the curb. Maintain tension on the lifting straps while using blocks.
Page 1 of 4 Edition 05/10/01
ii
4. The contractor shall instruct personnel on the proper use of hard -hats, and other
required safety equipment.
5. The contractor shall adhere to all OSHA and code requirements to insure the
safety of the public and job -site personnel.
PREPARATION for REMOVAL of OLD UNITS
1. Prepare to remove the old units. Many old units have lifting lugs which can be
used to remove the units. Occasionally the old lifting lugs will have been
removed and new lugs or lifting eyes will have to be provided by the contractor.
Check this prior to the arrival of the new units. Avoid the extra cost of delaying
the crane on the day the new units are to be rigged.
2. When lifting lugs are inadequate or missing, it will be necessary to lift (by
whatever means is appropriate) portions of the unit to allow placing cables under
the unit. Be very CAUTIOUS about pieces falling off the old unit while it is
being lifted.
3. Make arrangements for an electrician and a control technician to be present during
the removal of the old units. Power wiring and control wiring (or tubing) must be
properly handled to allow using it with the new units.
4. The rigger must have a crane (or helicopter) with enough capacity to lift the new
units (and remove the old units which may be stuck to the curb). Having a
properly sized crane may seem obvious; but, several times a year, we observe a
poorly prepared rigger attempting to lift a unit using an undersized crane. This
results in delays to obtain a larger crane or cobbling up some means of adding
additional counterbalances. Not only is this expensive; it can also be dangerous.
Seasons•4 submittals include the shipping weights of the units. The rigger should
always allow a minimum 10% safety factor to accommodate variations in rigging
requirements caused by unexpected jobsite conditions.
5. Disconnect the old unit's wiring, piping, etc.. Disconnect the wiring from the old
unit terminals. Do not cut the wiring. It will be reused for the new units. Ducts
must be loose prior to lifting units.
6. CAUTION! The duct connection on most existing units is a simple gasketed
compression fit. However, some existing units have their ductwork attached to
the unit in such a way as to prevent detachment while the old unit rests on the
curb. Sometimes the ductwork was screwed to the unit's underside and it was
impossible to see this before the old unit was lifted. Also, they didn't always
fasten all the ducts to the unit. Therefore, the following precautions must be
exercised:
A. The contractor shall instruct the crane operator to slowly and carefully
cable up when lifting the old unit. Lifting the supply end first is
suggested.
B. The contractor should assign a spotter at the supply air and return air duct
locations.
Page 2 of 4 Edition 05/10/01
C. As the cable is lifting the unit, the spotters must immediately communicate
if the ductwork is tightly fastened to the bottom of the unit (ducts rising
with the unit). If the duct is fastened to the unit, STOP the lifting
immediately.
D. The contractor must determine the location, type, and extent of
attachments (may require more careful lifting).
E. When screws have been used to attach the duct, it will be necessary to use
a long- handled chisel and a hammer to break off the screw heads.
Sometimes it is possible to pry between the bottom of the unit and the duct
next to each screw head (shearing off the screw head).
F. Every effort should be made to avoid cutting the flexible connections.
This will require rebuilding the duct prior to setting the new unit.
ARRIVAL of the NEW UNITS
1. The customer must inspect the new units for damage prior to accepting the
shipment and clearly describe any damage on the bill of lading. Note: This
inspection should include looking inside the unit for damage. Do this before
signing the bill of lading and have the driver acknowledge the damage. Contact
Carol Johnson at Seasons•4 (770- 489 -0716) and report the extent of the damage.
Also, send a copy of the bill of lading to her for use in discussions with the
trucking company.
2. Find and remove the curb gasket material (and drive cleats and duct angles when
included) which is shipped in the unit (a label on the unit tells the location). Send
these items up to the location of the unit being replaced. They will be needed
when the old unit is removed and prior to setting the new unit.
PREPARATION FOR SETTING THE NEW UNITS
1. The rigger should have proper rigging materials -- long enough straps or cables,
spreader bars, different sized shackles, and "scuff' blocks. Note: Spreader bars
(or cables a minimum of 40 feet long) must be used to avoid damage to the new
unit. Damage to the unit during rigging is the responsibility of the rigger.
2. Seasons•4 units include multiple lifting lugs. Use them all. The units must be
lifted level. Adjust the rigging to provide a level lift. If the unit is not level, it
will be very difficult to properly locate it on the existing curb.
3. Remove the old units. Scrape old gaskets from curb and ducts to provide a clean
surface for the new gaskets.
4. Make certain the old ducts are properly supported. If supports are required for the
old ducts, sheetmetal angles included with the new Seasons•4 units can be used.
"S and Drive" clips and angles will be included with the Seasons•4 units to
provide a flat surface to seal the old ducts to the new unit.
5. The seal between the old ducts and the new units is a compression fit; therefore,
Page 3 of 4 Edition 05/10/01
. ti <- �..'.':1..:i�uM:l
the ducts must be properly supported and must be flush with the top of the roof
curb. The bottom of the Seasons•4 units is designed for the supply and return
ducts to be flush with the top of the roof curb. Install a layer of gasket material
around the curb and around each duct. Use two layers if necessary to assure a
good seal.
6. Some old units had the condensing section installed over a weatherproof platform.
Rubber /cork pads will be included with the new Seasons•4 unit to build up this
platform to provide a level surface. The Seasons•4 specialist can advise on the
proper location of these pads.
RIGGING & SETTING the UNIT
1. Prepare unit for rigging. Remove shipping straps used to secure access doors
during shipment. If rigging straps or cables pass in front of the control panel
door, the return air compartment door, or a ChW /HW /Steam piping access door,
open the doors prior to connecting the rigging. Access to the inside of the control
panel is necessary to guide the power wiring into the unit during final setting.
Access to piping may also be necessary. It is also necessary to view the return air '
duct.
2. Check rigging. Spreader bars or 40 foot straps must be used to lift the unit.
Check to make sure lifting cables or straps are clear of door handles and /or
louvers. Use "scuff' blocks if necessary to prevent damage to the unit. Lift the
new unit to the vicinity of the old unit's curb.
3. Remove the casing panel located under the zone damper control access doors or
on the sides of the unit to allow viewing the individual zones prior to trying to set
the unit on the curb. If the new unit has a ducted return air connection, make sure
the access door to the return air opening is free of the lifting cables or straps.
Check to make certain that none of the access doors outlined above are blocked
shut by the lifting cables or straps. You must be able to open them when setting
the new unit.
4. Lower the new unit to within a foot of the curb. Remove the plate from the
bottom of the wiring chase(s) and pull the power and control wiring into the unit.
Be careful to avoid "skinning" the wiring and make sure it doesn't fall back down
inside the curb. Check alignment of any piping connections.
5. Proceed with lowering the unit into place. Check duct alignment (both supply and
return air). Make adjustments to assure proper sealing of the ducts to the unit.
6. Remove the rigging and replace the end panel used to view the zone connections.
Caulk the end panel to assure a weather tight seal.
The unit is now ready for completion of the installation. See "Installation & Start -up
Instructions — Seasons -4 Products" included with the unit.

INSTALLATION & START UP INSTRUCTIONS
SEASONS -4 PRODUCTS
These instructions are intended to provide a general guide for completing the installation and start
up of Seasons -4 units. They are not all inclusive and the installing contractor and sub - contractors
should become familiar with the complete sequence of operation for the complete project. The
Seasons -4 technician supervising the start up of the equipment is most familiar with the equipment
only. Additional expertise should be provided by the installing contractor.
MULTI - SECTION UNITS
Units shipped in multiple sections (to comply with rigging or shipping restrictions) must be
assembled (and refrigeration piping must be completed as required).
1. Multiple sections are usually shipped bolted together to better survive the rigors of shipment.
Remove the bolts on the base and the flanges inside the sections. Also, remove the cap strip
from the standing seam on the roof.
2. Installing contractor should remove all shipping straps and protective panels. Replace screws
in the same holes as the screws used for the shipping straps.
3. Split sections should be matched with labels located on the split sections of the unit.
4. Carefully lift individual sections and check to make sure there is no interference between
sections. When possible, rig the heaviest section first and place it in its final location on the
building.
5. Prior to rigging the next section in to place, apply a double bead of caulk liberally to the joint
between the sections.
6. Rig the second section to match up with the first section as closely as possible. A few extra
minutes to properly locate the additional section(s) will simplify the final process of bolting
them together. Use a "drift" or similar tool to align the main flanges on the base of the unit.
7. When sections are properly aligned and "snug" together, bolt the base (external) and internal
flanges (walls and roof) together with the factory provided hardware.
8. The unit must be caulked inside and outside at the joints (roof, base, and sides) to avoid any
leaks.
9. Install insulation and the casing cover panel at the split joints on both sides. The cover panel
holes should line up because the panels were previously installed at the factory.
10. Caulk and install the roof cleats. Secure the cleat by driving screws every 18 ". Be sure to
apply plenty of caulk at the roof joint before installing the cleats.
11. On multi- section units with refrigerant lines run between sections, the refrigerant lines will
have been installed at the factory with "slip couplings" placed on the lines prior to cutting.
Page 1 of 7 Edition 05/10/01
Please note: The lines have been cut at the factory prior to shipment. They must be realigned
at the jobsite and the "slip coupling" must be properly positioned. Complete the joint using
accepted good practices using a 95% copper - 5% silver solder.
12. Most split system (multi- section or separate air handling unit with remote condensing unit) •
shipments will have the refrigerant lines sealed with a holding charge of dry nitrogen and R 22.
Release the pressure before cutting the lines. Connection of refrigerant lines between sections
should follow the same soldering practice outlined above for split units.
13. Complete refrigerant piping and pressurize the system to 35 PSIG with R 22. Then increase
the pressure to 175 PSIG with dry nitrogen. Leak check to prevent loss of refrigerant.
14. After the unit has been thoroughly leak checked, purge each circuit and evacuate (when the
ambient is above 60 F) to 1500 microns. At 1500 microns, close the gauge manifold valves
tightly, remove the line from the vacuum pump, and connect to a refrigerant cylinder of R 22.
Loosen the common hose connection at the gauge manifold, crack the refrigerant drum valve to
purge the hose, and retighten the hose connection. Crack the valves on the gauge manifold
open until the system pressure rises to 2 PSIG. Close the refrigerant drum valve and the gauge
manifold valves.
15. The above evacuation procedure should be repeated three times, evacuating twice to 1500
microns, and the last time to 500 microns. Use an electronic vacuum gauge. The system is
now ready for charging with refrigerant.
16. Charge the unit with refrigerant (R -22) as estimated and recommended for the unit. Verify the
sight glass is clear and the subcooling is at 10 F with all the condenser fans running. (Some
split units will have been shipped with most of the charge valved off in the condensing section.
It may be necessary for the installing contractor to provide additional refrigerant to complete
the charge.)
17. The control and power wiring between sections will have been terminated with plug in
terminals or will require installation of electrical wire nuts or lug clamps and insulators
(included). Observe wire colors and terminal numbers
18. Go on to the next section of these instructions.
COMPLETION of the INSTALLATION
1. Installing contractor should remove all shipping straps and protective panels. Replace screws
in the same holes as the screws used for the shipping straps.
2. Install any louvers which were shipped inside the cabinet. Caulk the louvers to assure a
weather tight seal.
3. Install any hoods which were shipped inside the cabinet.
4. Install heater vent caps if unit includes gas heat.
5. When the unit includes gas heat, complete the gas piping following local codes.
Page 2 of 7 Edition 05/10/01
•
6. When the unit includes Chilled Water, Hot Water, or Steam coils, complete the piping with
controls and specialties as indicated on the project plans and as specified in the Seasons -4
submittal data.
7. Note: On replacement (RES) series units, the piping connections on the unit are located in •
close proximity to where the lines were on the old unit; but, it will be necessary for the
plumber to make slight modifications to the existing piping in order to complete the final
connection to the unit.
8. Remove shipping blocks from fans and check for free "floating" movement.
9. Remove shipping blocks from compressor spring isolators (if used). Replace the shipping nuts
with the rubber grommets and the special locking nuts fastened to the compressor. Reuse the
large washer on the mounting bolts. Run the locking nuts down to within a quarter of an inch
of the top of the washer.
10. Connect the power wiring to the unit.
11. Connect the control wiring to the unit or coordinate the installation of new controls with the
control contractor.
12. Note! When controls are provided by others and mounted by Seasons -4, a representative
of the controls supplier must be present during checkout and start up of the new unit.
CHECK, TEST, & START UP
1. The blowers, DX cooling, and gas heating on all Seasons -4 units is test run at the factory prior
to shipment. Units can normally be placed into operation with a minimum of adjustment.
2. The DX cooling cycle of new units must be placed into operation by the installing contractor
under the supervision of an authorized representative of Seasons -4. This may be done at the
time of rigging or may be later, depending on individual project schedules. When start up is
required at some time after setting the equipment in place, please notify the Seasons -4 Service
Department (770- 489 -0716) a minimum of two weeks prior to the requested date.
3. When the job requires operation of the fans to test for proper airflow, or when heating is
required prior to the requirement for cooling, the installing contractor may place the fans into
operation without the presence of an authorized representative of Seasons -4. Contact the
Seasons -4 Service Department (770- 489 -0716) for specific authorization. Please see
additional instructions as outlined below.
4. Make certain all service switches (24 volt, compressors, fans, heat, etc.) are in the "OFF"
position.
5. Check the voltage to the unit to make certain it agrees with the unit nameplate.
6. Close the main power disconnect switch. All the motors in the unit have been properly phased
out at the factory during final testing. Check the phase monitor in the control panel for proper
jobsite phasing of the unit (no light indicates improper phasing, green light on indicates proper
phasing). Reverse phases if necessary - only on the line side of the unit.

7. Check all wiring terminal connections and tighten if necessary.
8. Check to make sure the return air damper (when included) is open.
9. Turn on the 24 volt control power switch. Turn on the supply air fan switch. Check for proper
rotation. Check amperage to make sure it is within the "nameplate" rating of the fan motor.
Repeat this procedure for the return air fan if it is used. Note: Do not turn on any
compressor switches!
10. A rough ride to the jobsite on the truck can occasionally cause the drive belts to become
misaligned. Check the alignment of the fan drive belts and realign if necessary.
11. Regardless of whether the complete unit is to be operated, open the compressor discharge
valves. This will avoid blowing a head gasket should the compressor cycle for any reason.
12. Do not turn on the compressors until an authorized Seasons -4 representative is present to
oversee the startup of the unit. Again, Seasons -4 will make every effort to meet the startup
timetable required by the project and we ask for at least two weeks notice to work our schedule
into the startup schedule.
13. When the Seasons -4 representative arrives at the job, the installing contractor must have a fully
equipped HVAC service technician to perform the startup. Others who may benefit from
instruction should also be present for any required service and maintenance training.
14. Seasons -4 units are engineered to provide performance based on project documentation. If any
questions of performance are raised, Seasons -4 will do everything possible to assist in
resolving the problem. A complete copy of the test and balance report will usually be
necessary to provide this assistance.
CONDENSING UNIT START UP
1. Check the setting and operation of the outside ambient lockout switch. The normal switch
settings are: Open below 50 ° F. Closed above 50 ° F.
2. Connect service gages to the compressor suction and discharge gage connections.
3. Open service valves on the discharge line leaving the compressor, the suction line entering the
compressor, the liquid line leaving the condenser, and the hot gas bypass line (if included).
See the Seasons -4 0 & M Manual if receiver is included.
4. Verify the unit has refrigerant in it (pressure against ambient temperature).
5. Turn on the 24 volt control power switch. Turn on the SA and RA (if applicable) fans. Turn
on the # 1 compressor pump down switch. Compressor will usually start and pump down if the
temperature controls are not calling for cooling.
6. Adjust temperature controls to call for cooling. In approximately 5 minutes, the compressor
should start. Check compressor operating amps against full load nameplate.
7. Check rotation and amperage of condenser fans.
Page 4 of 7 Edition 05/10/01
8. On unloading type compressors controlled from temperature, make sure the compressor is fully
loaded (adjust temperature controls to cause this action).
9. On unloading type compressors controlled from suction pressure, check the setting of the
unloader pressure switches. Switches are factory adjusted to cut in (unload) at 55 PSIG and to
cut out (load) at 75 PSIG.
10. If amps are nornial, allow the compressor to run and determine stable operating pressures.
Record operating pressures and amperage.
11. Unload compressor by stages and record operating characteristics.
12. Close the liquid line solenoid valve (using temperature controls) and watch compressor pump
down. Record cutoff point setting of the low pressure control. Factory setting = cut out at 25
PSIG, cut in at 55 PSIG.
13. Call for cooling through the control sequence and verify the operation of the 5- minute anti -
cycle time delay for the liquid line solenoid valve and the compressor. Record the cut in point
of the low pressure control.
14. Pull fuses or a control wire on the condenser fans to simulate a high head pressure condition
and record the cut out setting of the high pressure switch. Factory setting = cut out at 375
PSIG. Switch has manual reset.
15. Replace fuses on condenser fans and allow head pressure to return to normal. High pressure
switch must be manually reset. The compressor will run after the 5- minute time delay.
16. Close the liquid line valve to check the operation of the hot gas bypass valve (if included). The
line downstream of the HGB valve will get warm (hot) when the valve opens. Record the
valve opening pressure. Factory setting = 50 PSIG. After verifying proper operation of the
HGB valve, reopen the liquid line valve. The HGB valve setting is adjustable.
17. Turn off the # 1 compressor pump down switch. Recheck pump down sequence.
18. Repeat steps 1 through 17 for additional compressors. (Note: Skip step 16 if the compressor
does not have a HGB circuit.)
19. When all compressor circuits have been checked out, turn on all circuits and check out their
response to the temperature control system. (See below)
CHILLED WATER COOLING
1. Complete connection of the chilled water piping to the chilled water coil. Piping specialties
and control valves (if required) must also be installed at the jobsite. Fill the system with water
and check for leaks. Initiate the flow of water to the coil.
2. Turn on the unit's blower(s).
3. Using the unit's temperature controls to simulate a call for heating, verify the control valve
opens and closes responding to calls for cooling.

HEATING
Seasons -4 units are manufactured with different types of heating including indirect fired natural
gas, electric, hot water, and steam. The contractor's start up service person should become familiar
with the type heater as outlined in the Seasons -4 0 & M Manual included with the unit.
The following checks are intended to provide a general guide to assist the technician in starting the
unit.
1. Check to make sure the "heater switch" is OFF. On natural gas fired units, purge the gas line to
get gas to the unit. Caution! Do not purge the gas line with controls calling for operation of
the heater.
2. Indirect fired natural gas - gravity furnace. Note: Unit must be provided with a natural gas
supply at a pressure between 7" and 14" WC. If gas pressure is outside these limits, installing
contractor must make the necessary adjustments. With the unit's heater switch off, open the
manual gas valve to the unit. Verify the inlet gas pressure to be within the limits stated above.
The gas pressure must remain above 7" WC at the 100% firing rate.
3. Set the unit's temperature controls to call for the first stage of heat. Turn the heater switch on.
The gas valve should open and the heater should ignite. Note: If unit has two gravity furnaces,
check the operation of each furnace.
4. Set temperature controls to call for the second stage of heat.
5. Indirect fired natural gas - power burner furnace. Note: Unit must be provided with a natural
gas supply at a pressure between 7" and 14" WC. If gas pressure is outside these limits,
installing contractor must make the necessary adjustments. With the unit's heater switch off,
open the manual gas valve to the unit.. Verify the inlet gas pressure to be within the limits
stated above. The gas pressure must remain above 7" WC at the 100% firing rate.
6. Set the unit's temperature controls to call for the first or minimum stage of heat. Turn the
heater switch on. The gas valve should open and the heater should ignite.
7. Set the unit's temperature control to call for additional stages of heat.
8. Electric heat: Set the unit's temperature controls to call for the first stage (only) of heat. Turn
the heater switch on. Verify the_first stage of heat is on.
9. Set the unit's temperature controls to call for additional stages of heat. Verify each stage.
10. Set the unit's temperature controls to call for full heat. Record heater amperage.
11. Hot water or steam heat. Using the unit's temperature controls to simulate a call for heating,
verify the control valve opens and closes.
12. When all heater circuits have been checked out, turn on all circuits and check out their
response to the temperature control system. (See below)

TEMPERATURE CONTROLS
Seasons -4 units are manufactured with an almost unlimited variety of control systems including
electric /electronic, pneumatic, and Direct Digital Control. The contractor's start up service person
should become familiar with the sequence of operation for the complete unit and the Automatic
Temperature Control (ATC) contractor should be present to assist with the interface between unit
controls and field mounted controls in the building. When the factory mounted controls have been
provided by the project ATC, the ATC must be present to complete the checkout of the unit.
The following checks are intended to provide a general guide and limited to a few options. The
contractor's start up service person should become familiar with the Sequence of Control as
described in the unit's specifications portion of the Seasons -4 0 & M manual included with the
unit.
1. OA/RA Economizer. When electric /electronic controls are provided, check out the operation
of the economizer. In the absence of a test and balance technician actually measuring the
CFM, adjust the minimum position potentiometer on the OA/RA damper motor(s) so the OA
damper is about 15% open or an approximate angle of about 20 from vertical. Verify that OA
damper closes when the unit is deactivated.
2. Using the unit's temperature controls, simulate a call for economizer operation. Verify the
outside air changeover control (enthalpy or sensible) enables the economizer system. Set the
changeover control at the setting indicated in the 0 & M Manual.
3. Morning warm -up (if included). Unit will have a morning warns up thermostat located in the
return air to the unit and set at approximately 70 ° F. Verify its operation.
4. Zone dampers (if included). With help from the ATC, verify that space zones are coordinated
with the unit's zones. Verify that a call for cooling in each zone opens its cooling zone damper
and a call for heating causes the heating zone damper to open. Do this for each zone.
5. If the outdoor ambient is above the setting of the economizer changeover thermostat, set zone
dampers to call for cooling. Verify the operation of the compressors.
6. If the outdoor ambient is below the setting of the economizer changeover thermostat, set the
zone dampers to call for heating. Verify the operation of the heater(s).
7. Variable Air Volume (VAV). The control of the air volume from the Seasons -4 unit is usually
accomplished with a Variable Frequency Drive. This drive will have been programmed at the
factory. Verify the pressure setting of the drive and its operation. See 0 & M manual for
additional information.
When other types of control systems are used on the unit, information on those systems is included
in the Seasons -4 0 & M manual. The Seasons -4 technician will be familiar with the other control
systems and will offer advice on interfacing these systems with the Seasons -4 equipment.
