general information
Single packaged heat pumps are ready for easy and
immediate installation and can be readily connected
into the high static duct system of a home. This unit is
completely assembled, wired, and run tested at the factory.
This heat pump is designed for outdoor installation
only. The only connections needed for installation are the
supply and return ducts, the line voltage, and thermostat
wiring. Use of components other than those specified may
invalidate AHRI Certification, Code Agency Listing, and
limited warranty on the air conditioner.
Before You Install this Unit
√ The cooling load of the area to be conditioned must be
calculated and a system of the proper capacity selected.
It is recommended that the area to be conditioned be
completely insulated and vapor sealed.
√ Check the electrical supply and verify the power supply
is adequate for unit operation. If there is any question
concerning the power supply, contact the local power
company.
√ All units are securely packed at the time of shipment and
upon arrival should be carefully inspected for damage
prior to installing the equipment at the job site. Verify
coil fins are straight. If necessary, comb fins to remove
flattened or bent fins. Claims for damage should be filed
immediately with the carrier.
√ Please consult your dealer for maintenance information
and availability of maintenance contracts. Please read
all instructions before installing the unit.
Locating the Heat Pump
• 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.
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.
Service Access Clearance:
Blower access panel side........................................... 24”
Electrical compartment access panel side................ 12”
Clearance between overhang and top
of unit ................................................................... 72”
Clearance around condenser coil area to
wall or shrubs (excludes duct panel side)................... 12”
Unpacking the Unit
It is recommended that the unit be unpacked at the
installation site to minimize damage due to handling.

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 (Figure 3, page 6), 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.
• 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
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.

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. 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 (Figure 4,
page 7) 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.
1.Thread the elbow provided with the unit into the drain
connection until hand tight.
2.Connect the condensate tubing onto the fitting, forming
a trap (Figure 6) near the drain connection.
3.Route the condensate tube from the trap to a suitable
drain. NOTE: For proper drainage, make sure the trap
is level to the ground and tubing outlet is below trap
level.

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.
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.

Overcurrent Protection
Overcurrent protection must be provided at the branch
circuit distribution panel and sized as shown on the unit
rating label and according to applicable local codes.
Generally, the best fuse or breaker for any heat pump
is the smallest size that will permit the equipment to run
under normal usage and provide maximum equipment
protection. Properly sized fuses and breakers also prevent
nuisance trips during unit startup. If a fuse blows or a
breaker trips, always determine the reason. Do not
arbitrarily install a larger fuse or breaker and do not,
in any case, exceed the maximum size listed on the
data label of the unit.
Grounding
WARNING:
CAUTION:
Supply Wire
Length (Feet)
• Units are shipped from the factory wired for 240 volt
transformer operation. For 208V operation, remove the
lead from the transformer terminal marked 240V and
connect it to the terminal marked 208V.
The unit cabinet must have an uninterrupted or
unbroken electrical ground to minimize personal
injury if an electrical fault should occur. Do not
use gas piping as an electrical ground!
This unit must be electrically grounded in accordance
with local codes or, in the absence of local codes, with
the National Electrical Code (ANSI/NFPA 70) or the CSA
C22.1 Electrical Code. Use the grounding lug provided in
the control box for grounding the unit.
Thermostat Connections
• The heat-cool thermostat is equipped with a system
HEAT-COOL switch, which provides a positive means
of preventing simultaneous operation of the heating and
cooling units. The thermostat is also equipped with an
ON-AUTO fan switch which allows the home owner to
operate the indoor blower when air circulation is desired.
• Connect the low voltage wires to the respective terminals
on the thermostat base (Figure 12, page 23). See
thermostat instruction sheet for more detailed wiring
information.
• The thermostat should be mounted about 5 feet above the
floor on an inside wall. DO NOT install the thermostat on
an outside wall or any other location where its operation
may be adversely affected by radiant heat from fireplaces,
sunlight, or lighting fixtures, and convective heat from
warm air registers or electrical appliances. Refer to the
thermostat manufacturer’s instruction sheet for detailed
mounting information.
Defrost Cycle Control
The defrost cycle is initiated via a signal from the defrost
sensor on the outdoor coil to the defrost control board inside
the control panel. This indicates the coil temperature is low
enough to start accumulating frost. The board has interval
settings of 30, 60, and 90 minutes. These time intervals
represent the time elapsed before defrosting cycle starts
and they are dependent on the climate conditions of the
installation. A 30 minute setting would be recommended
in a moist climate such as Seattle Washington. A 90
minute setting would be adequate in a dry climate such
as southern Arizona. The factory time interval setting is
30 minutes.
Defrost Control Board
Operational Information
• Terminals R - C must have 24V present between
them for the time delay and defrost sequences to be
operational.
• Defrost Thermostat (DFT) By-Pass - Jumping the
T2 & DFT test pins will communicate to the board that
the defrost thermostat is closed (if the compressor is
running). The defrost T-stat tells the board whether a
defrost cycle needs to be started or terminated.
NOTE: The defrost T-stat is closed at 30° F or below
and is open at 68° F or above, but its state is unknown
if the temperature is between 30° F and 68° F.
• With the DFT closed, the unit will run for 30/60/90
minutes in heat mode and then defrost the outdoor
coil. The defrost will turn off the outdoor fan, energize
the reversing valve, and turn on the compressor raising
the coil temperature to 68° F. This will open the DFT
and terminate the defrost. If the DFT does not open,
the defrost will end after 10 minutes.
• Defrost Board Speed Up - Jumping the TEST terminal
to the C (common) terminal (while the compressor is in
heat mode) will over-ride the defrost board and initiate a
faster defrost test in 5, 10 or 15 seconds as determined
by the 30, 60 or 90 minute defrost pin settings (factory
setting is 30 minutes).
– The compressor off delay is also bypassed when the
unit goes into defrost test. If unit is kept in defrost
test, the delay will be bypassed when the test is
terminated by the processor.
NOTE: If the jumper is removed before the test is over,
the processor will perform the remainder of a normal
defrost as noted above.
• The delay/no-delay pin affects compressor operation
during defrosts. The default setting is delay. To switch
from delay to no-delay, remove the pin from the delay
pin location and move it to the no-delay pin location.
- Scroll compressors that have noise issues while
going into or coming out of defrost should use this
30 second delay to reduce the defrost noise.
Normal Mode
To test normal defrost operation when the temperature is
above 35° F, jumper R to DFT on the board and allow the
unit to run for 30 minutes. Defrost will continue until the
R to DFT jumper is removed or for 10 minutes. Remove
the jumper.
The 5 minute time delay feature can be shortened 1 time
to 1 second by jumping the Test to C terminal. Remove
the jumper and repeat as desired. NOTE: If jumper is left
on the Test to common pins permanently, the defrost
cycle will be inoperable.
Speed Up Mode (Testing Procedure)
1.Jumper T2 to DFT at the test terminals.
2.With unit running in heat mode, jump the TEST terminal
to the C (common) terminal near it. The board will
speed up and enter defrost mode in 5/10/15 seconds,
depending on the defrost time selection. Compressor
delay will not function during speed-up. NOTE: Manually
initiating a defrost will cause the compressor to run
continually when entering defrost.
3.This test will end in 5 seconds if the TEST - common
short is not removed.
4.Remove both the short and the T2 to DFT jumper to
terminate the defrost cycle. The 30 second compressor
delay should operate normally.
5.Test is complete, reset thermostat to the equipment
owner’s preference.
Electric Heat Package (optional)
This heat pump is shipped without an auxiliary electric
heat kit installed. If electric heat is desired, an accessory
heater kit must be field installed. Refer to Table 2 (page
10) for blower speeds.
• Select the correct size heat package for the installation.
See specifications sheet for available kits and application.
Install the heater kit according to the to the installation
instructions provided with the kit.
• Installation is most easily accomplished before making
duct or electrical connections.
Outdoor Thermostat (Factory Option)
The outdoor thermostat prevents the electrical auxillary
heat (if used) from operating above a desired set point.
The factory temperature setting is 40° F.

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:
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.
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.
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.
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.
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.
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.
Adjustment of Refrigerant Charge
CAUTION:
• The unit must be charged while both first and second
stages are operating.
• 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.
11
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 the cooling charging tables (Tables 3–8 pages
14–16) to verify system conditions for proper charge
amount.
Charging the Unit in Heating Mode
1.Evacuate the refrigerant system.
2.Weigh in the proper charge as shown on the unit rating
plate. Use the charging tables for heating mode of
operation as a guide (Tables 9 - 14, pages 17 - 19).
Unit charge MUST be verified in cooling season.
3.Verify the unit is operating properly according to the
System Heating section on page 11.
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:
• 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.
12
• 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.
Component Functions
Low Pressure Switch - This switch 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.
High Pressure Switch - This 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.
