Locating the Heat Pump
12"
24"
Before You Install this Unit
• Survey the job site to determine the best location for
mounting the outdoor unit. Select a solid, level position,
preferably on a concrete slab, slightly above the grade
level, and parallel to the home. If possible, select a site
for the unit that is as close as possible to the proposed
return grille location. DO NOT PLACE UNIT UNDER
THE HOME.
• The unit should be located with consideration of
minimizing the length of the supply and return ducts
with no sharp radius bends. If practical, place the heat
pump and its ducts in an area where they will be shaded
from the afternoon sun, when the heat load is greatest.
• Consideration should also be given to availability of
electric power, service access, noise, and shade.
• Overhead obstructions, poorly ventilated areas, and
areas subject to accumulation of debris should be
avoided. The hot condenser air must be discharged up
and away from the home, and if possible, in a direction
with the prevailing wind. Do not place the unit in a confined
space. See Figure 8 (page 13) for unit dimensions.
• Sufficient clearance for unobstructed airflow through the
outdoor coil must be maintained in order to achieve rated
performance. For minimum clearances to obstructions,
see Figure 1.
Minimum Clearances
Minimum clearances MUST be maintained from adjacent
structures to provide room for proper servicing and air
circulation. DO NOT install unit in a confined or recessed
area that will allow discharge air from the unit to re-circulate
into the condenser air inlet, through the coil. See Figure 1.

Air Duct System
Air ducts should be installed in accordance with the
standards of the National Fire Protection Association
“Standard for Installation of Air Conditioning and Ventilation
Systems” (NFPA 90A), “Standard for Installation of
Residence Type Warm Air Heating and Air Conditioning
Systems” (NFPA 90B), these instructions, and all applicable
codes. NFPA publications are available by writing to:
National Fire Protection Association, Batterymarch Park,
Quincy, ME 02269 or visit www.NFPA.org on the web.
• Design the duct work according to methods described
by the Air Conditioning Contractors of America (ACCA).
• The supply duct system, including the number and type of
registers, will have much more effect on the performance
of the system than any other factor. The duct must be
sufficiently large to conduct an adequate amount of air
to each register. See Figure 3 (page 6).
• Duct work should be attached directly to the unit flanges
for horizontal applications.
• For highly resistive duct systems it may be necessary
to add an additional return air duct and or supply to
achieve maximum performance and prevent coil icing
and refrigerant flood back.
• The heat pump system will not cool or heat the home
if air is lost to the outside through leaks in the duct
system. Ducts that are collapsed or restricted by
foreign objects will also prevent adequate air flow.
• All duct work passing through unconditioned space
must be properly insulated to minimize duct losses
and prevent condensation. Use insulation with an outer
vapor barrier. Refer to local codes for insulation material
requirements.
Unconditioned Spaces
The heat pump system will not cool or heat the home
if air is lost to the outside through leaks in the duct
system. Ducts that are collapsed or restricted by
foreign objects will also prevent adequate air flow.
HEAT PUMP INSTALLATION
Unpacking the Unit
It is recommended that the unit be unpacked at the
installation site to minimize damage due to handling.
CAUTION:
Do not tip the unit on its side. Oil may enter the
compressor cylinders and cause starting trouble.

screw holes underneath the slotted end.
2.Fasten the collar ends with two self drilling sheet metal
screws.
3.Position the collar over the opening and align the 4 holes
in the collar with the 4 holes (or dimples depending on
model) in the rear panel.
4.Using self-drilling screws (10-16x.5), secure the collar
to the rear panel.
Return Duct
1.Assemble the collar by overlapping the two ends.
NOTE: One end of the collar is slotted and the opposite
end has two small holes. Position the end with small
screw holes underneath the slotted end.
2.Fasten the collar ends with two self drilling sheet metal
screws.
3.Position the collar over the opening. Align the four holes
in the collar with the four dimples or holes (depending
on unit model) in the panel.
4.Secure the collar to the rear panel using self tapping
screws (10-16x.5).
Connecting Return & Supply Air Flexible Ducts
• Flexible ducts may be cut to the required length and
spliced with sheet metal sleeves and clamps. Keep all
ducts as short and straight as possible. Avoid sharp
bends. Please follow all instructions packed with duct.
• Flexible ducts can be secured to the corresponding
collars with the provided clamps. After the inner duct is
connected to the collar, pull the insulation and plastic
sleeve over the connection and clamp. NOTE: To prevent
a loss in cooling capacity, make sure all connections
are tight.
6
• Homes with multiple supply ducts (or special
applications), a Y fitting is available for dividing the
supply air to different areas of the home for more efficient
cooling. NOTE: For maximum performance, insulate the
Y fitting.
Locating & Installing the Return Air Assembly
To simplify installation, locate and install the return air
assembly first. See Figure 4 (page 7). If desired, the
return opening can be located inside a closet with louvered
doors that has an open area equal to or greater than a
12” x 20” grille. The return air grille can be placed in the
wall of a closet and the ducted into the filter box through
a boxed-in area at the closet floor level. Make sure the
filter is readily accessible.
NOTE: The return air box with grille and filter should not
be located in heavy traffic areas like hallways or center
of rooms. A good spot is in a corner or under a table, if a
minimum two inch clearance is available.
1.Start the installation from under the home by cutting a
small hole in the sub-floor. Determine how the floor joist
location will affect cutting the opening needed for the
return air box. NOTE: Floor joists are generally located
on 16” centers, leaving 14-3/8” between joists.
2.After measuring the return air box (approximately 121/4” x 20-1/4”), cut the hole through the floor so that
the box will fit between the floor joists. Care should be
taken when cutting through carpeting to avoid snags.
NOTE: In most installations it will be necessary to cut
a similar hole in the fiberboard directly under the hole
in the floor. However, if the floor is more than ten inches
deep, it will only be necessary to cut a hole for the collar
on the return air box or for the insulated duct.
3.Set the box into the opening and fasten with screws or
nails.
4.Install the filter and return air grille in place.
Locating & Installing the Supply Damper(s)
When locating the supply damper(s), carefully check
floor joists and frame members that could interfere with
the installation of the damper or flexible duct. Ideally, the
damper (Figure 5) should be located in the bottom of the
main duct, forward of center of the home, at least three
feet from the nearest register. The round supply opening
in the slanted side of the damper should face the side of
the home where the heat pump is located.
Figure 4. Return Air Assembly
1.Locate the center of the heat duct by cutting a small
hole in the fiberboard below the duct at the desired
location.
2.Cut a hole approximately 3/4” larger than the damper
opening in the fiberboard.
3.Cut a 9-1/8” x 13-1/8” hole in the duct and bend over
all tabs flat on the inside of the heat duct.
4.Insert the damper into the duct and bend over all tabs
flat on the inside of the heat duct.
5.Seal the opening between the fiberboard and damper
or flexible duct.

Startup & adjustments
Pre-Start Checklist
The following check list should be observed prior to
starting the unit.
√ Is the unit level? Unit should be level or slightly slanted
toward the drain for proper condensate drainage.
√ Is the unit installed with the proper clearances as listed
on page 5?
√Is the wiring correct according to the wiring diagram
and electrical codes?
√ Are all the wiring connections tight? Check the condenser
fan to make sure it turns freely.
√Is the overcurrent protection properly sized?
√Is the thermostat wired correctly? Is it installed in a
proper location?
√ To achieve rated capacity and efficiency the compressor
must be exposed to refrigerant for at least 24 hours prior
to running and then must be run for a minimum of 12
hours.
Start-Up Procedure
The control circuit consists of an anti-short cycle timer
that will not let the compressor re-start before 5 minutes
have elapsed.
1.Set the system mode to OFF and the temperature mode
to its highest setting.
2.Turn power on at the disconnect switch.
3.Set the system mode to ON or COOL.
4.Set the temperature mode below room temperature.
Verify that the indoor blower, outdoor fan, and
compressor energize and the cooling function starts.
5.Verify the discharge air grilles are adjusted and the
system air is balanced.
6.Verify the duct work has no air leaks.
7.Verify the condensate drain is installed correctly and
functions properly.
8.Set the temperature mode above room temperature.
The unit should stop.
9.Instruct the homeowner on unit and thermostat operation
and filter servicing.
Air Circulation
Leave the thermostat system mode on OFF, and set the
fan mode to ON. Blower should run continuously. Check
the air delivery at the supply registers and adjust register
openings for balanced air distribution. Examine ducts for
leaks or obstruction if insufficient air is detected.
Set the thermostat fan mode to AUTO. The blower should
stop running.
System Heating
Set the thermostat system mode to HEAT and the fan mode
to AUTO. Change the thermostat temperature selector
above the existing room temperature and check for the
discharge of warm air at the supply registers.
System Cooling
Set the thermostat’s system mode to COOL and the
fan mode to AUTO. Change the thermostat temperature
selector below the existing room temperature. Allow the
cooling system to operate for several minutes and check
for the discharge of cool air at the supply registers.
Short Cycle Protection
The control circuit is equipped with a time-delay feature
for protection against short cycling. With the system
operating in the cooling mode, gradually raise the
thermostat temperature setting until the whole system deenergizes. Immediately lower the thermostat temperature
to the original setting and verify that the indoor blower is
energized. After approximately 5 minutes the compressor
and the outdoor fan will energize.
Emergency Heat
(Available only when Electric heat is supplied) Set the
thermostat’s system mode to EM HT and the fan mode
to either AUTO (intermittent air) or to ON (continuous air).
Change the thermostat’s temperature selector above the
existing room temperature and check the following:
1.The thermostat auxiliary heat light (RED) should be on.
2.The heat pump compressor and the fan should not run;
low voltage circuit remains energized.
3.The blower will run according to the thermostat’s fan
mode setting.
Anti Short Cycle Timer Test
The 5 minute time delay feature can be bypassed by
shorting the TEST pins together.
Heating Mode
When the TEST pins are shorted together for more than
1 second, the control will switch between defrost mode
and heating mode.
Cooling Mode
When the TEST pins are shorted together for more than
1 second, the Anti Short Cycle Timer will be bypassed.
Unit MAINTENANCE
WARNING:
To prevent electrical shock, personal injury, or
death, disconnect all electrical power to the unit
before performing any maintenance or service.
The unit may have more than one electrical supply.
Proper maintenance is important to achieve optimum
performance from the heat pump. The ability to properly
perform maintenance on this equipment requires certain
mechanical skills and tools. If you do not possess these
skills, contact your dealer for maintenance. Consult your
local dealer about the availability of maintenance contracts.
Routine maintenance should include the following:
11
• Inspect and clean or replace air filters at the beginning
of each heating and cooling season, or more frequently
if required.
• Inspect the condensate drain and outdoor coil at the
beginning of each cooling season. Remove any debris.
Clean the outdoor coil and louvers as necessary using
a mild detergent and water. Rinse thoroughly with water.
• Inspect the electrical connections for tightness at the
beginning of each heating and cooling season. Service
as necessary.
CAUTION:
The unit should never be operated without a
filter in the return air system. Replace disposable
filters with the same type and size.
• Do not attempt to add additional oil to motors unequipped
with oil tubes. The compressor is hermetically sealed
at the factory and does not require lubrication.
Adjustment of Refrigerant Charge
CAUTION:
This heat pump contains liquid and gaseous
refrigerant under pressure. Adjustment of
refrigerant charge should only be attempted
by qualified, trained personnel thoroughly
familiar with the equipment and safe responsible
refrigerant handling procedures. Under no
circumstances should the homeowner attempt
to install and/or service this equipment. Failure
to comply with this warning could result in
equipment damage, personal injury, or death.
Charging the Unit in AC Mode
(with Outdoor Temperatures Above 65° F)
1.With the system operating at steady-state, measure
the suction and liquid refrigerant pressures (in psig) at
the service valves.
2.Measure the compressor discharge temperature (° F).
3.Use Table 4 (page 14), Table 5 (page 14), Table 6
(page 15), Table 7 (page 15), Table 8 (page 16),
or Table 9 (page 16) to verify system conditions
(during cooling mode) for proper charge amount.
Charging the Unit in Heating Mode
1.Evacuate the refrigerant system.
2.Use Table 10 (page 17), Table 11 (page 17), Table
12 (page 17), Table 13 (page 18), Table 14 (page
18), or Table 15 (page 18), as a guide and weigh
in the proper charge as shown on the unit rating plate
(during heating mode operation). NOTE: Unit charge
MUST be verified in cooling season.
3.Verify the unit is operating properly according to the
System Heating section on page 11.
Safety Switches
• The low pressure switch (if equipped) is factory installed
and located in the suction line internal to the unit. The
switch is designed to protect the compressor if a loss
of charge occurs. Under normal conditions, the switch
is closed.
If the suction pressure falls below 5 psig, then the switch
will open and de-energize the unit. The switch will close
again once the suction pressure increases above 20
psig. The low pressure switch interrupts the thermostat
inputs to the unit. NOTE: When the switch opens and
then closes, there will be a 5 minute short cycling delay
before the unit can energize.
• The high pressure switch is factory installed and located
in the compressor discharge line internal to the unit.
The switch is designed to de-energize the system when
very high pressures occur during abnormal conditions.
Under normal conditions, the switch is closed.
If the discharge pressure rises above 650 psig, the switch
will open and de-energize the unit. The switch will close
again once the discharge pressure decreases to 460
psig. The high pressure switch interrupts the thermostat
inputs to the unit. NOTE: When the switch opens and then
closes, there will be a 5 minute short cycling delay before
the unit can energize.
