III. INTRODUCTION
This booklet contains the installation and operating instructions for your package heat
pump. There are a few precautions that should be taken to derive maximum satisfaction
from it. Improper installation can result in unsatisfactory operation or dangerous conditions.
Read this booklet and any instructions packaged with separate equipment required to
make up the system prior to installation. Give this booklet to the owner and explain its
provisions. The owner should retain this booklet for future reference.
NOTE: A load calculation must be performed to properly determine the required heating
and cooling for the structure. Also, the duct must be properly designed and installed for
proper airflow. Existing dutwork must be inspected for proper size and sealed system.
Proper airflow is necessary for both user comfort and equipment performance.
IMPORTANT: Proper application, installation and maintenance of this equipment is a
must if consumers are to receiver the full benefit for which they have paid.
A. R-410A REFRIGERANT
All units are factory charged with R-410A refrigerant.
1. Specification of R-410A:
Application: R-410A is not a drop-in replacement for R-22; equipment designs must
accommodate its higher pressures. It cannot be retrofitted into R-22 units.
Pressure: The pressure of R-410A is approximately 60% (1.6 times) greater than R-
22. Recovery and recycle equipment, pumps, hoses and the like need to have design
pressure ratings appropriate for R-410A. Manifold sets need to range up to 800 psig
high-side and 250 psig low-side with a 550 psig low-side retard. Hoses need to have a
service pressure rating of 800 psig. Recovery cylinders need to have a 400 psig service
pressure rating. DOT 4BA400 or DOT BW400.
Combustibility: At pressures above 1 atmosphere, mixture of R-410A and air can
become combustible. R-410A and air should never be mixed in tanks or supply
lines, or be allowed to accumulate in storage tanks. Leak checking should never
be done with a mixture of R-410A and air. Leak checking can be performed safely
with nitrogen or a mixture of R-410A and nitrogen.
2. Quick Reference Guide For R-410A
• R-410A refrigerant operates at approximately 60% higher pressure (1.6 times) than R-
22. Ensure that servicing equipment is designed to operate with R-410A.
• R-410A refrigerant cylinders are pink.
• R-410A, as with other HFC’s is only compatible with POE oils.
• Vacuum pumps will not remove moisture from POE oil.
• R-410A systems are to be charged with liquid refrigerants. Prior to March 1999, R410A refrigerant cylinders had a dip tube. These cylinders should be kept upright for
equipment charging. Post March 1999 cylinders do not have a dip tube and should be
inverted to ensure liquid charging of the equipment.
• Do not install a suction line filter drier in the liquid line.
• A liquid line filter drier is standard on every unit.
• Desiccant (drying agent) must be compatible for POE oils and R-410A.
3. Evaporator Coil / TXV
The thermostatic expansion valve is specifically designed to operate with R-410A. DO
NOT use an R-22 TXV. The existing evaporator must be replaced with the factory
specified TXV evaporator specifically designed for R-410A.
4. Tools Required For Installing & Servicing R-410A Models
Manifold Sets:
-Up to 800 PSIG High side
-Up to 250 PSIG Low Side
-550 PSIG Low Side Retard
Manifold Hoses:
-Service Pressure Rating of 800 PSIG
5
Recovery Cylinders:
-400 PSIG Pressure Rating
-Dept. of Transportation 4BA400 or BW400
!
CAUTION
R-410A systems operate at higher pressures than R-22 systems. Do not use
R-22 service equipment or components on R-410A equipment.
IV. CHECKING PRODUCT RECEIVED
Upon receiving the unit, inspect it for any damage from shipment. Claims for damage,
either shipping or concealed, should be filed immediately with the shipping company.
Check the unit model number, heating size, electrical characteristics, and accessories to
determine if they are correct.
V. EQUIPMENT PROTECTION FROM THE
V. ENVIRONMENT
The metal parts of this unit may be subject to rust or deterioration in adverse environmental conditions. This oxidation could shorten the equipment’s useful life. Salt spray,
fog or mist in seacoast areas, sulphur or chlorine from lawn watering systems, and various chemical contaminants from industries such as paper mills and petroleum refineries
are especially corrosive.
If the unit is to be installed in an area where contaminants are likely to be a problem, special attention should be given to the equipment location and exposure.
1. Avoid having lawn sprinkler heads spray direction on the unit cabinet.
2. In coastal areas, locate the unit on the side of the building away from the waterfront.
3. Shielding provided by a fence or shrubs may give some protection.
Regular maintenance will reduce the buildup of contaminents and help to protect
the unit’s finish.
WARNING
!
DISCONNECT ALL POWER TO THE UNIT BEFORE STARTING MAINTENANCE.
FAILURE TO DO SO CAN RESULT IN SE VERE E LECTRICAL SHOCK OR
DEATH.
1. Frequent washing of the cabinet, fan blade and coil with fresh water will remove
most of the salt or other contaminants that build up on the unit.
2. Regular cleaning and waxing of the cabinet with a good automobile polish will provide some protection.
3. A good liquid cleaner may be used several times a year to remove matter that will
not wash off with water.
Several different types of protective coatings are offered in some areas. These coatings
may provide some benefit, but the effectiveness of such coating materials cannot be verified by the equipment manufacturer.
The best protection is frequent cleaning, maintenance and minimal exposure to
contaminants.

2. LOCATION
These units are designed for outdoor installations. They can be mounted on a
slab or rooftop. They are not to be installed within any part of a structure such as
an attic, crawl space, closet, or any other place where condenser air flow is
restricted or other than outdoor ambient conditions prevail. Since the application
of the units is of the outdoor type, it is important to consult your local code authorities at the time the first installation is made.
B. OUTSIDE SLAB INSTALLATION
(Typical outdoor slab installations are shown in Figures 9 and 10.)
1. Select a location where external water drainage cannot collect around the unit.
2. Provide a level concrete slab extending 3" beyond all four sides of the unit. The
slab should be sufficient above grade to prevent ground water from entering the
unit. IMPORTANT: To prevent transmission of noise or vibration, slab should not
be connected to building structure.
3. The location of the unit should be such as to provide proper access for inspection
and servicing.
4. Locate unit where operating sounds will not disturb owner or neighbors.
5. Locate unit so roof runoff water does not pour directly on the unit. Provide gutter
or other shielding at roof level. Do not locate unit in an area where excessive
snow drifting may occur or accumulate.
6. It is essential that the unit be elevated above the base pad to allow for condensate drainage and possible refreezing of condensation. Provide a base pad which
is slightly pitched away from the structure. Route condensate off base pad to an
area which will not become slippery and result in personal injury.
7. Where snowfall is anticipated, the height of the unit above the ground level must
be considered. Mount unit high enough to be above average area snowfall and to
allow for proper condensate drainage.

C. CLEARANCES
The following minimum clearances must be observed for proper unit performance
and serviceability.
1. Provide 48" minimum clearance at the front of the unit. Provide 36" minimum
clearance at the left and right side of the unit for service access.
2. Provide 60" minimum clearance between top of unit and maximum 3 foot overhang.
3. Unit is design certified for application on combustible flooring with 0" minimum
clearance.
4. See Figure 9 for illustration of minimum installation-service clearances.
D. ROOFTOP INSTALLATION
1. Before locating the unit on the roof, make sure that the strength of the roof and
beams is adequate at that point to support the weight involved. (See specification
sheet for weight of unit.) This is very important and user’s responsibility.
2. For rigging and roofcurb details, see Figures 11 and 12. Use field-furnished
spreaders.
3. For roofcurb assembly, see Roofcurb Installation Instructions.
4. If the roofcurb is not used, provisions for disposing of condensate water runoff
during defrosting must be provided.
5. The unit should be placed on a solid and level roofcurb or platform of adequate
strength. See Figure 13.
6. The location of the unit on the roof should be such as to provide proper access for
inspection and servicing.
IMPORTANT: If unit will not be put into service immediately, cover supply and return
openings to prevent excessive condensation.
VII. DUCTWORK
Ductwork should be fabricated by the installing contractor in accordance with local codes
and NFPA90A. Industry manuals may be used as a guide when sizing and designing the
duct system - contact Air Conditioning Contractors of America, 1513 16th St. N.W.,
Washington, D.C. 20036.

WARNING
!
DO NOT, UNDER ANY CIRCUMSTANCES, CONNECT RETURN DUCTWORK TO
ANY OTHER HEAT PRODUCING DEVICE SUCH AS A FIREPLACE INSERT,
STOVE, ETC. UNAUTHORIZED USE OF SUCH DEVICES MAY RESULT IN FIRE,
CA RBO N M ONO XIDE POISON ING , E XPLOSION , P ROP ERT Y D AMAGE ,
SEVERE PERSONAL INJURY OR DEATH.
The unit should be placed as close to the space to be air conditioned as possible allowing clearance dimensions as indicated. Ducts should be run as directly as possible to
supply and return outlets. Use of non-flammable waterproof flexible connectors on both
supply and return connections at the unit to reduce noise transmission is recommended.
It is preferable to install the unit on the roof of the structure if the registers or diffusers
are located on the wall or in the ceiling. A slab installation could be considered when the
registers are low on a wall or in the floor.
On ductwork exposed to outside air conditions of temperature and humidity, use a minimum of 2" of insulation and a vapor barrier. Distribution system in attic, furred space or
crawl space should be insulated with at least 2" of insulation with vapor barrier. One-half
to 1" thickness of insulation is usually sufficient for ductwork inside the air conditioned
space.
Balancing dampers should be provided for each branch duct in the supply system.
Ductwork should be properly supported from the structure.
When installing ductwork, consider the following items:
1. Noncombustible flexible connectors should be used between ductwork and unit to
reduce noise and vibration transmission into the ductwork.
2. When auxiliary heaters are installed, use noncombustible flexible connectors and
clearance to combustible material of 0" for the first 3 feet of discharge duct.
Clearance to unit top and side is 0".

VIII.FILTERS
This unit is provided with 2 - 25" x 16" x 1" (3-5 ton) 4 - 16" x 16" x 1" (6 ton) disposable
filters. When replacing filters, ensure they are inserted fully to the back to prevent
bypass.
IX. CONVERSION PROCEDURE
DOWNFLOW TO HORIZONTAL
1. Remove the screws and covers from the outside of the supply and return sections.
2. Install the covers in the bottom supply and return openings with the painted side up.
See Figure 15. Use the existing gasket to seal the covers.
3. Secure the supply cover to the base of the unit with 1 screw, engaging prepunched
tab in unit base.
4. Secure the return cover to the base of the unit with screws, engaging prepunched
holes in the unit base.

exceeding 50', use #16 AWG thermostat wire. The low voltage wires are connected
to the unit pigtails which are supplied with the unit below the unit control box.
3. It is necessary that only heat pump thermostats be used.
4. Figure 18 shows representative low voltage connection diagrams. Read your thermostat installation instructions for any special requirements for your specific thermostat.
NOTE — Units installed in Canada require that an outdoor thermostat (30,000 min.
cycles of endurance) be installed and be wired with C.E.C. Class I wiring.

D. INTERNAL WIRING
1. A diagram of the internal wiring of this unit is located on the inside of the compressor access panel. If any of the original wire as supplied with the appliance must be
replaced, the wire gauge and insulation must be the same as original wiring.
IMPORTANT: Some single phase units are equipped with a single pole contactor.
Caution must be exercised when servicing as only one leg of the power supply is broken with the contactor. Some models are equipped with electrically commutated blower motors which are constantly energized unless the main unit disconnect is in the off
position.
E. GROUNDING
WARNING
!
THE UNIT MUST BE PERMANENTLY GROUNDED. A GROUNDING LUG IS PROVIDED IN THE ELECTRIC HEAT ACCESS AREA FOR A GROUND WIRE. FAILURE
TO GROUND THIS UNIT CAN RESULT IN FIRE OR ELECTRICAL SHOCK CAUSING PROPERTY DAMAGE, SEVERE PERSONAL INJURY OR DEATH.
F. THERMOSTAT
The thermostat should be mounted on an inside wall about five feet above the floor in
a location where it will not be affected by unconditioned air, sun, or drafts from open
doors or other sources. READ installation instructions in heat pump thermostat package CAREFULLY because each has some different wiring requirements.
XIII. INDOOR AIR FLOW DATA
Direct-drive blower models are shipped factory wired for the proper speed at a typical
external static. Belt-drive blower models have motor sheaves set for proper CFM at a
typical external static.

8. Is unit elevated to allow for outdoor coil condensate drainage during heating opera-
tion and defrost?
XVI. STARTUP
1. Turn thermostat to “OFF,” turn “on” power supply at disconnect switch.
2. Turn temperature setting as high as it will go.
3. Turn fan switch to “ON.”
4. Indoor blower should run. Be sure it is running in the right direction.
5. Turn fan switch to “AUTO.” Turn system switch to “COOL” and turn temperature set-
ting below room temperature. Unit should run in cooling mode.
6. Is outdoor fan operating correctly in the right direction?
7. Is compressor running correctly.
8. Turn thermostat system switch to “HEAT.” Unit should stop. Wait 5 minutes, then
raise temperature setting to above room temperature. Unit should run in heating
mode and after about 30 to 50 seconds auxiliary heaters, if installed, should come
on.
9. Check the refrigerant charge using the instructions located on compressor access
panel cover. Replace service port caps. Service port cores are for system access
only and will leak if not tightly capped.

XVII. OPERATION
Most single phase units are operated PSC (no start relay or start capacitor). It is important that such systems be off for a minimum of 5 minutes before restarting to allow
equalization of pressures. The thermostat should not be moved to cycle unit without
waiting five minutes. To do so may cause the compressor to stop on an automatic open
overload device or blow a fuse. Poor electrical service can cause nuisance tripping in
overloads or blow fuses.
IMPORTANT: The compressor has an internal overload protector. Under some condi-
ions, it can take up to 2 hours for this overload to reset. Make sure overload has had
t
time to reset before condemning the compressor.
Some units are equipped with a time delay control (TDC1). The control allows the blower
to operate for up to 90 seconds after the thermostat is satisfied.
XVIII. AUXILIARY HEAT
The amount of auxiliary heat required depends on the heat loss of the structure to be
heated and the capacity of the heat pump. It is good practice to install strip heat to maintain at least 60ºF indoor temperatures in case of compressor failure. The auxiliary heat
s energized by the second stage of the thermostat. The amount of electric heat that is
i
allowed to come on, as determined by the output of the heat pump, may be controlled by
an outdoor thermostat.
WARNING
!
ONLY ELECTRIC HEATER KITS SUPPLIED BY THIS MANUFACTURER AS
DESCRIBED IN THIS PUBLICATION HAVE BEEN DESIGNED, TESTED, AND
EVALUATED BY A NATIONALLY RECOGNIZED SAFETY TESTING AGENCY
FOR USE WITH THIS UNIT. USE OF ANY OTHER MANUFACTURED ELECTRIC
HEATERS INSTALLED WITHIN THIS UNIT MAY CAUSE HAZARDOUS CONDITIONS RESULTING IN PROPERTY DAMAGE, FIRE , BODILY INJU RY OR
DEATH.
A. CONTROL SYSTEM OPERATION
1. In the cooling mode, the thermostat will, on a call for cooling, energize the compressor contactor and the indoor blower relay. The indoor blower can be operated
continuously by setting the thermostat fan switch at the “ON” position. The reversing valve coil is de-energized.
2. In the heating mode, the first heat stage of the thermostat will energize the compressor contactor and the indoor blower relay. The second heat stage will turn on
one or more supplementary resistance heaters. The reversing valve is energized
except in defrost. If required or considered desirable, the resistance heat may
also be controlled by outdoor thermostats.
XIX. DEMAND DEFROST CONTROL AND
HIGH/LOW PRESSURE CONTROLS
The demand defrost control is a printed circuit board assembly consisting of solid
state control devices with electro-mechanical outputs. The demand defrost control
monitors the outdoor ambient temperature, outdoor coil temperature, and the compressor run-time to determine when a defrost cycle is required.
Enhanced Feature Demand Defrost Control: Has high and low pressure control
inputs with unique pressure switch logic built into the microprocessor to provide
compressor and system protection without nuisance lock-outs. Cycles the compressor off for 30 seconds at the beginning and end of the defrost cycle to eliminate the
increased compressor noise caused by rapidly changing system pressures when
the reversing valve switches. See the end of this section for diagnostic flash codes
for the two diagnostic LED’s provided on the control.
DEFROST INITIATION
A defrost will be initiated when the three conditions below are satisfied:
1) The outdoor coil temperature is below 35°F.
2) The compressor has operated for at least 34 minutes with the outdoor coil temperature below 35°F.
3) The measured difference between the ambient temperature and the outdoor
coil temperature is greater than the calculated delta T.
Additionally, a defrost will be initiated if six hours of accumulated compressor runtime has elapsed without a defrost with the outdoor coil temperature below 35°F.
19
DEFROST TERMINATION
Once a defrost is initiated, the defrost will continue until fourteen minutes has
elapsed or the coil temperature has reached the terminate temperature. The terminate temperature is factory set at 70°F, although the temperature can be changed
to 50°F, 60°F, 70°F or 80°F by relocating a jumper on the board.
TEMPERATURE SENSORS
The coil sensor is clipped to the outdoor coil. The air sensor is located in the outdoor coil compartment.
If the ambient sensor fails the defrost control will initiate a defrost every 34 minutes
with the coil temperature below 35°F.
If the coil sensor fails the defrost control will not initiate a defrost.
TEST MODE
The test mode is initiated by shorting the TEST pins. In this mode of operation, the
enable temperature is ignored and all timers are sped up by a factor of 240. To initiate a manual defrost, short the TEST pins. Remove the short when the system
switches to defrost mode. The defrost will terminate on time (14 minutes) or when
the termination temperature has been achieved. Short TEST pins again to terminate
the defrost immediately.
TROUBLE SHOOTING DEMAND DEFROST
Set the indoor thermostat select switch to heat and initiate a call for heat.
Jumper the “test pins” to put the unit into defrost. If the unit goes into defrost and
comes back out of defrost, the indication is that the control is working properly.
If the unit did not go into defrost using the test pins, check to ensure that 24V is
being supplied to the control board. If 24V is present then replace the control.
HIGH/LOW PRESSURE CONTROL MONITORING - ENHANCED
DEFROST CONTROL
Status of high and low pressure controls is monitored by the enhanced feature
demand defrost control and the following actions are taken.
High Pressure Control – Provides active protection in both cooling and heating
modes at all outdoor ambient temperatures. The high pressure control is an automatic reset type and opens at approximately 610 psig and closes at approximately
420 psig. The compressor and fan motor will stop when the high pressure control
opens and will start again if the high side pressure drops to approximately 420 psig
when the automatic reset high pressure control resets. If the high pressure control
opens 3 times within a particular call for heating or cooling operation, the defrost
control will lock out compressor and outdoor fan operation.
Low Pressure Control – Provides active protection in both heating and cooling
modes at all outdoor ambient temperatures. The low pressure control is an automatic reset type and opens at approximately 15 psig and closes at approximately
40 psig. Operation is slightly different between cooling and heating modes.
Cooling Mode: The compressor and fan motor will stop when the low pressure
control opens and will start again when the low side pressure rises to approximately 40 psig when the low pressure control automatically resets. If the low
pressure switch opens 3 times within a particular call for cooling operation, the
defrost control will lock out compressor and outdoor fan operation.
Heating Mode: The compressor and fan motor will stop when the low pressure
control opens and will start again when the low side pressure rises to approximately 40 psig when the low pressure control automatically resets. If the low
pressure switch trips 3 times within 120 minutes of operation during a particular
call for heating operation, the defrost control will lock out compressor and outdoor fan operation. If the lock-out due to low pressure occurs at an outdoor
ambient temperature below 5°F, the defrost control will automatically exit the
lock-out mode when the outdoor ambient temperature rises to 5°F. This feature
is necessary since the low pressure control could possibly have opened due to
the outdoor ambient being very low rather than an actual system fault.
20
Exiting Lock-Out Mode:
control by removing power to indoor air-handler/furnace or by shorting the two
defrost control test pins together.
To exit the lock-out mode, remove 24 volts to the defrost
