Unit Location
Several important factors must be considered before selecting
the site for this unit:
1. Site – Select a solid level position, preferably on a concrete
slab, slightly above grade level and parallel to the home.
2. Proximity to home or building – The length of the supply
and return ducts should be kept to a minimum with no
sharp bends. Consideration should be given to the
distance and routing of electrical service to connect the
unit. Try to select a site for the unit that it is as close as
possible to the proposed return grille location. Unit may be
positioned to draw air from underneath structure.
3. Proximity to the clothes dryer vent – The clothes dryer vent
should not be located upwind from the unit.
4. Ability to service – Side access panels of the unit should
not be closer than 24 inches to a structure so blower and
controls may be serviced.
5. Sound transmission – Locate the unit away from bedroom
windows or other rooms where sound may be objectionable.
6. Air Circulation – The outside coil sides should not be
closer than 24 inches to a structure that will restrict air flow
through the coil. The air discharge of the unit requires a 60-
inch clearance between the top of the unit and any
obstruction.See Figure 2.
7. Wind direction – The hot condenser air must be discharged
up and away from the home or building, and if possible in a
direction with the prevailing wind.
8. Relationship between building, sun and unit – If practical,
place the air conditioner in an area where the unit and the
ducts will be shaded from the afternoon sun (when the heat
load is the greatest).
9. Defrost and Water Drainage - Water will run off the outdoor
coil when the heat pump defrosts during the heating
season. This water will run through the drain holes of the
heat pump base pan onto the ground below. A slight grade
away from the unit will improve drainage.
10. Average Winter Snow Depth - The heat pump must be
installed above the average snow depth to allow the
outdoor coil to drain properly.
Cinder blocks, if permitted by local codes, or a metal frame
may be used to support the unit above the snow. Insure
that the support does not obstruct drainage holes in the
base pan of the unit. Metal frame legs must be supported
by concrete pads. The heat pump must set level and
securely upon the support.
NOTE: If installing on blocks, the middle rail must be supported.
Figure 2: Air Discharge Clearance
Site Preparation
After the site has been selected and prepared, using criteria
mentioned above, install the air conditioner support pad at the
selected site.
NOTE: This unit must be installed and operated on a level
surface. Failure to do so will result in condensate
drainage problems.

Installing Of Duct To Unit
(Manufactured Housing)
Flanges for round ducts are packed with the unit.The unit’s supply
and return air connections are sized for optimum performance.
Should the ductwork connecting to the air conditioner be of
smaller dimensions, it is recommended that transitions
connecting the ducts to the unit be constructed to allow a
smooth airflow to the air conditioner’s return air opening and
from the supply air opening. Abrupt duct size changes increase
the system static pressure and reduces air volume which may
cause unsatisfactory performance. Duct-work should be in
accordance with Local and National Codes.
Ductwork exposed to outside environmental conditions must be
insulated and weather proofed. Out-side wall openings through
which the ducts pass must be weather proofed in accordance
with Local and National Codes.
Supply and return air ducts passing through unconditioned
spaces of the building must be insulated and covered with a
vapor barrier. Following this practice will prevent thermal losses
and condensate formation on the ducts.
Supply and Return Ducts
Duct should be sized to accommodate a maximum of .8” water
column. Metal ducts may be used when properly insulated and
vapor proofed. Any duct used should be covered with insulation
having a minimum R-value of 4.0 or in accordance with any
local codes or standards regarding duct material. Insulation
must be covered with a vapor barrier. Install the air conditioning
duct connections to the unit. Insure that the seam is towards
bottom. A good quality duct tape should be used to insure an
airtight installation.
The Return — Air Grille Boxes
The return air grille assembly should be installed first. The
return air grille box and filter should be located and installed in
the “out-rigger” areas of the home. Keep in mind, the closer to
the cooling unit, the better. The return ducting connects to the
bottom of the return air box so it will be necessary to provide an
opening beneath the box. See Figure 5.
Figure 5: Return Air Box and Grille
After determining the location of the return air opening, start
installation from beneath the manufactured home.
1. Cut a small hole in the fiber under board to determine floor
joist location.Floor joists are generally located on 16”
centers, leaving 14-3/8” between joists.
2. Cut a 12-1/2” x 20-1/2” rectangular hole in the floor
between two joists.
3. Set the return box into the opening and mark a circular
pattern on the fiber under board through the flex duct
connector collar, then remove the return box from the
opening.
4. Cut outside of the circular mark to allow enough space to
pull the flex duct up through the hole and fasten to the
return box.

When installing this air conditioning system in
conjunction with a furnace, a damper must be installed
in the furnace to prevent cold air being discharged
around the heat exchanger. The presence of such cold
air could damage the heat exchanger and could cause
asphyxiation.A damper, part number 7900-6771* is
available for use on Unitary Products Group
manufactured housing gas and oil furnaces. (See 7900-
6771* damper assembly installation instructions packed
with the damper assembly for more in-formation. For
other makes of furnaces, check with the furnace
manufacturer for damper requirements.

5. When attaching the flex duct to the return air box, secure
the duct collar and return box collar together with at least
three (3) sheet metal screws and seal with duct tape.
6. Set the return air box, with flex duct attached, back into the
floor opening.
7. Fasten the return air box securely to the floor with screws
or nails.
8. Seal fiber under board hole around flex duct.
For ease of installation of the flexible ductwork, it is
recommended that as much work as possible be done outside
the underneath area of the manufactured home. Accurate
measurements are required. Plan the ducting configuration well
and double check the measurements.
Check the intended routing and length required of the flexible
duct.
Remember, each slight change in direction of the duct add
static resistance and reduces airflow.
Keep flexible ducts straight and short. Wide sweeping bends
should be used when turns are necessary, not sharp corners or
angles.
1. When return air grille box is installed, run the duct to the
return air inlet flange on the unit.
2. Cut the duct to the required length using a knife, or tin
snips, and cut the helical wire with a wire cutter.
3. Insert a stub collar in the raw end of the duct and tape
securely in place.
4. Make sure the duct is not stretched tight and does not have
kinks from excessive length after installation.
5. Attach the duct end, with the stub collar, to the air
conditioner return air flange with screws and duct tape
sealing the duct cover securely.
Wye Insulation
It is necessary to field fabricate and install an insulation jacket
for the Wye. Insulation will prevent loss of capacity especially
where the gain or loss is critical in a borderline installation. See
Figures 6 and 7.
1. Use “faced” batt insulation material.
2. Place the insulation on the topside of the Wye, with the
faced or vinyl side out.
3. Tape to insulation placed on bottom of Wye and tape
together “diaper style”.
4. Make sure a tight bond is obtained and attach to flexible
duct sleeves with tape.
5. Tape insulation to return air opening flange, airtight.
NOTE: The insulation should not be compressed around the
Wye. This defeats the purpose of the insulation.

Discharge Duct Installation
If an interior furnace or air handler will be connected to the
supply duct system, the supply duct connector should be
equipped with a damper. See Figure 8.
If no interior furnace or air handler will be connected to the
ductwork, the duct connector may be a 12”diameter round duct.
See Figure 9.
When locating the duct connector, check carefully for floor
joists, axles, wheels and frame members that could interfere
with the installation of the duct connector or the running of the
duct. Ideally, the duct connector should be located in the bottom
of the main duct, forward of center of the manufactured home.
Do not install duct connector under a register.This will help to
eliminate the transmission of sound into the home.
To locate the center of the duct, first cut a 6” hole in the
fiberboard below the duct at the desired location.After locating
the duct center, increase the hole in the fiber board to
approximately the size of the duct connector.

If using the duct connector with damper, cut a 9-1/8”x 16-1/8”
hole in the center of the duct bottom. If using the 12” diameter
duct connector without damper cut a 12-1/8” diameter hole in
the center of the duct bottom. Place the duct connector in the
hole and secure tightly with the tabs. If necessary, sup-port duct
connector with support braces. See Figures 6 & 7.
NOTE: It is advisable to tape joints at the duct connector
airtight. There is extreme pressure exerted by the
blower at this point.
Installing Of Duct To Unit (Residential)
Flanges are provided to help install the ducts to the air
conditioner. The duct flanges must be field in-stalled on the
unit’s side.
The unit’s supply and return air connections are sized for
optimum performance. Should the duct work connecting to the
air conditioner be of smaller dimensions, it is recommended that
transitions connecting the ducts to the unit be constructed to
allow a smooth airflow to the heat unit’s return air opening and
from the supply air opening. Abrupt duct size changes increase
the system static pressure and reduces air volume which may
cause unsatisfactory performance.
Ductwork should be in accordance with local and national
codes.
Ductwork exposed to outside environmental conditions must be
insulated and weather proofed. Out-side wall openings through
which the ducts pass must be weather proofed in accordance
with good construction practices.
Supply and return air ducts passing through unconditioned
spaces of the building must be insulated and covered with a
vapor barrier. Following this practice will prevent thermal losses
and condensate formation on the ducts.
Installing Drain Tube And Connection
A drain tube, a barbed elbow plastic fitting, and a plastic hose
clamp are provided in the small parts package packed in the
blower chute.
1. To insure proper condensate drainage, the barbed plastic
elbow fitting should be screwed into the unit drain fitting
(located in the front corner of the unit), and the drain tube
installed on the barbed end of the plastic fitting secured in
plastic fitting with the plastic hose clamp.
2. If it is necessary to drain water away from unit, attach a
drain hose to the drain tube.
Service Access
Access to all serviceable components is provided at the
following locations:
• Blower compartment access panel
• Control box access panel
Refer to Figure 1 for location of these access locations and
minimum clearances in Table 3.
The drain hose must not rise above the level of the drain
fitting at any point in its routing. Failure to do so will
result in condensate water overflowing into the unit’s
interior.
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system. Gage sets, hoses, refrigerant
containers and recovery systems must be designed to
handle R-410A. If you are unsure, consult the
equipment manufacturer. Failure to use R-410A
compatible servicing equipment may result in property
damage or injury.
Wear safety glasses and gloves when handling
refrigerants. Failure to follow this warning can cause
serious personal injury.

Compressors
The compressor used in this product is specifically designed to
operate with R-410A Refrigerant and cannot be interchanged.
The compressor also uses a polyolester (POE oil), Mobil 3MA
POE. This oil is extremely hydroscopic, meaning it absorbs
water readily. POE oil can absorb 15 times as much water as
other oils designed for HCFC and CFC refrigerants. Take all
necessary precautions to avoid exposure of the oil to the
atmosphere.
POE (polyolester) compressor lubricants are known to cause
long term damage to some synthetic roofing materials.
Procedures which risk oil leakage include, but are not limited to,
compressor replacement, repairing refrigerant leaks, replacing
refrigerant components such as filter drier, pressure switch,
metering device or coil.
Units are shipped with compressor mountings which are
factory-adjusted and ready for operation.
Power And Control Wiring
Field wiring to the unit must conform to provisions of the current
N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances.
The unit must be electrically grounded in accordance with local
codes or, in their absence, with the N.E.C./C.E.C. Voltage
tolerances which must be maintained at the compressor
terminals during starting and running conditions are indicated
on the unit Rating Plate and Table 5.
The wiring entering the cabinet must be provided with
mechanical strain relief.
A fused disconnect switch should be field provided for the unit.
If any of the wire supplied with the unit must be replaced,
replacement wire must be of the type shown on the wiring
diagram.
Electrical line must be sized properly to carry the load. Each
unit must be wired with a separate branch circuit fed directly
from the meter panel and properly fused.
Power Wiring
This heat pump is equipped to accept a single circuit of supply
power. If an auxiliary heater is installed, dual circuiting to the
unit can be used. When installing a 14.3 KW heater, this
method will avoid the use of large wiring. To provide single cir-
cuiting, an optional jumper bar can be used to electrically con-
nect the circuit breakers provided with the heater kit.
If auxiliary electric heaters are not installed, refer to data sheet
for minimum circuit ampacity and maximum overcurrent protec-
tive device size. If auxiliary electric heaters are being installed,
refer to the installation instructions (included with heater pack-
ages) for electrical requirements and wiring information.
To wire this system without the use of auxiliary electric heat,
remove the control box access door.
1. Remove side panel. Run power line service wiring into
control box through the bottom knockout opening in the
casing. (The two top knockouts are used when installing an
auxiliary heater.)
2. For single phase units - Connect one supply wire to L1 on
the contactor, and the other supply wire to L2 on the
contactor. Connect ground wire to ground lug in control
box. See Figure 10.
3. For three phase units - connect supply wires to L1, L2 and
L3 on the contactor. Connect ground wire to ground lug in
control box.
4. Unless the heat pump is grounded through proper wiring to
the service entrance ground terminal, a suitable separate
ground must be provided at the air conditioner.
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system.
Do not leave the system open to the atmosphere. Unit
damage could occur due to moisture being absorbed by
the POE oil in the system. This type of oil is highly
susceptible to moisture absorption
Exposure, even if immediately cleaned up, may cause
embrittlement (leading to cracking) to occur in one year
or more. When performing any service that may risk
exposure of compressor oil to the roof, take precautions
to protect roofing.
Do not loosen compressor mounting bolts.

Control Wiring
1. Run low voltage control circuit wires through the “fingered”
snap bushing into the low voltage compartment.
2. Run low voltage control circuit wires through the fingered
snap bushing to the low voltage terminal wire. Refer to
Figure 11 diagram to connect the low voltage control wiring
to the units low voltage connections.
3. If using auxiliary electric heat, refer to the wiring
instructions provided with the heating kit.
Figure 10: Unit Component Location
Figure 11: Thermostat Wiring
Wall Thermostat Installation
General recommendations for the location of the thermostat are
as follows:
The proper location of the room thermostat is most important to
insure that it will provide a comfortable home temperature.
Observe the following general rules when selecting a location:
1. Locate thermostat about 5 feet above floor.
2. Install on a partitioning wall, not on an outside wall.
3. Never expose it to direct light from lamps, sun, fireplaces,
etc.
4. Avoid locations close to doors that lead outside, to
windows or to adjoining outside walls.
5. Avoid locations close to radiators, warm air registers, or in
the direct path of heat or cold air from them.
6. Make sure that there are no pipes or ductwork in that part
of the wall chosen for thermostat location.
7. Never locate it in a room that is warmer or cooler than the
rest of the home, such as a kitchen or hallway.
8. The living or dining room is normally a good location
provided there is no cooking range or refrigerator on the
opposite side of wall.
Make final check of complete electrical system for correct
wiring. Check for any possible loose connections.

If installing this heat pump system in conjunction with a
gas furnace, a baffle must be installed in the furnace to
prevent cold air from being discharged around the heat
exchanger. This could damage the heat exchanger and
cause asphxiation. A sheet metal plate may be inserted
in the supply outlet duct of the furnace to serve as a
baffle. Advise the homeowner that the baffle plate
must be removed before attempting to operate the
interior furnace.
A thermostat interlock system must be provided to
prevent simultaneous operation of any furnace with the
heat pump. If a furnace will be in the home, a separate
furnace thermostat must be used and an interlock switch
(See Figure 12) must be installed in both thermostat
circuits, insuring only one thermostat can be operated at
a time. This switch must break the control circuit of any
furnace used.

Before starting air conditioner, make sure of the following:
1. The unit is properly located and level.
2. The ductwork is properly sized, insulated, weather proofed
and correctly spaced from combustible materials.
3. Air is free to flow to and from outdoor coil.
4. All wiring is correct, tight and according to the wiring
diagrams.
5. The unit is properly grounded electrically.
6. The condensate drain is connected and directed away from
the unit and structure.
7. The outdoor fan and indoor blower wheel will turn freely.
8. The indoor blower is factory wired to provide the correct
speed.
System Startup, Check-out
1. Insure that all access doors are in position. The wall
thermostat system switch should be in the OFF position,
the fan switch in the AUTO position and the emergency
heat switch in the NORM position.
2. The electrical power supply to the heat pump should be on
for 12 hours and the compressor crankcase heater (if
provided) is working.
3. Set the wall thermostat fan switch to ON. The outdoor
blower should run.
4. Set wall thermostat fan switch to AUTO. The indoor blower
should not run.
5. Set the wall thermostat system switch to COOL and the
temperature selection lever below the room temperature.
The heat pump should be running in the cooling mode.
6. Set the wall thermostat system switch to the HEAT
position. The heat pump should stop.
7. Raise the wall thermostat temperature selection lever to a
setting above the room temperature. The heat pump
should now run in the heating mode.
8. To check the emergency heat operation, set the wall
thermostat system switch to EMERGENCY HEAT. Raise
the wall thermostat temperature selection lever high
enough to close the second stage of the thermostat, if it is
not already closed. The indoor blower will turn on when the
heating elements stage on. If accessory heaters are not
installed, the blower will not run.
9. Set the wall thermostat to the seasonal mode of operation
(heat or cool), adjust the temperature selection lever to the
desired setting. Record the following information for your
service records after the heat pump has run for 20 minutes:
• Operating Mode ____________________________
• Discharge Pressure ________________________
• Suction Pressure __________________________
• Suction Line Temp. at Compressor ____________
• Indoor Dry Bulb Temperature _________________
• Indoor Wet Bulb Temperature _________________

• Outdoor Wet Bulb Temperature ________________
• Voltage at Contactor _________________________
• Current at Contactor _________________________
• Model Number _____________________________
• Serial Number _____________________________
• Owner ___________________________________
• Date _____________________________________
10. Reinstall all panels on the heat pump.
11. Check the heat pump system for tubing and sheet metal
rattles.
12. Instruct the owner on the operation and maintenance of
this heat pump system.
13. Give the Customer Envelope to the owner and explain why
the registration card should be filled out and returned.
Other Features Incorporated In The Control
Anti-Short Cycle time Delay
Five minute duration, activated each time the indoor thermostat
opens and each time the system is turned on. This delay may
be reduced by a ratio of 256:1 by shorting the “TEST" posts.
Safety Lock-Out
This device opens the circuit to the compressor contactor in
response to High Pressure Limit switch opening. The
compressor will remain off, even though the limit switches close
and will start up only when the Lock-out is reset.
The Lock-out also lights the Emergency Heat Indicator. To
reset the Lock-out momentarily turn the thermostat to “OFF"
then back to its original position. The unit will start up after the 5
minute delay, mentioned above.

Defrost Operation
The demand defrost control implements a temperature
differential (”delta-T”) demand defrost algorithm. The heat pump
is allowed to operate in the heating mode until the combination
of outdoor ambient and outdoor coil temperatures indicate that
defrosting is necessary (See Figure 13). When coil temperature
is below the initiate point for the ambient temperature
continuously for 4-1/2 minutes, the heat pump is put into a
defrost cycle. This 4-1/2 minute timer eliminates unnecessary
defrost cycles caused by refrigeration surges such as those that
occur at the start of a heating cycle.
A timed inhibit feature prevents the system from responding to
a call for defrost less than 20 minutes after the initiation of the
previous defrost. After the 20 minute inhibit time has expired,
temperature conditions must call for defrost continuously for 4-
1/2 minutes before a defrost cycle is initiated. A temperature
inhibit feature prohibits defrost if the coil temperature is above
40°F.
A forced-defrost feature puts the system into a defrost period
every 6 hours and 4 minutes to recirculate lubricants, unless the
coil temperature is above 40°F. All defrost timing occurs only
while the compressor is on.
During the defrost mode, the defrost control will provide a 24
volt signal from terminal “W1/66” to the fan control terminal
“W1”. This signal will energize electric heat stage 1, if the unit is
so equipped.
For trouble shooting purposes, the defrost cycle can be
manually initiated by shorting the “TEST” pins together for 5
seconds. Defrost will terminate normally during the “TEST”
mode.
