IMPORTANT:

Read this owner information to become familiar with the capabilities and use of your
appliance. Keep this with literature on other appliances where you have easy access to
it in the future. If a problem occurs, check the instructions and follow recommendations
given. If these suggestions don’t eliminate your problem, call your installing contractor or
distributor in your area.

INTRODUCTION

Your heat pump is a unique, all weather comfort­control system appliance. The basic operation
of the heating/cooling system is described
and illustrated on page 1 of this manual. The
surprising fact that heat exists in air even at
below-freezing temperatures is actually the
basic law of physics which the heat pump
uses to provide energy saving heating comfort.
At outdoor temperatures of 47° Fahrenheit

(or 8° Celsius), your heat pump can deliver
approximately 2 to 3 units of heat energy per each
unit of electrical energy used, as compared to a
maximum of only 1 unit of heat energy produced
with conventional heating systems. During the
cooling season, the heat pump reverses the fl ow
of the heat-absorbing refrigerant to become an
energy-effi cient, central air conditioner.

SECTION 1. OWNER INFORMATION

Your heat pump will heat and cool your home
year round, saving your energy dollars. During the
summer, a heat pump performs like any normal
air conditioner. That is, the excess heat energy
inside the home is absorbed by the refrigerant
and exhausted outside the home. During the
winter months, a heat pump performs like an
air conditioner run in reverse. That is, available
heat energy outside the home is absorbed by
the refrigerant and exhausted inside the home.
This is an effi cient heating means because you
only pay for “moving” the heat from the outdoors
to the indoor area. You do not pay to generate
the heat, as is the case with more traditional
furnace designs.

It is the sole responsibility of the homeowner
to make certain that the heat pump has been
correctly set up and adjusted to operate
properly.

A warranty certifi cate with full details is included
with the heat pump. However, the manufacturer
will not be responsible for any costs found neces­sary to correct problems due to improper setup,
improper installation, adjustments, improper op­erating procedure on the part of the user, etc.

Some specifi c examples of service calls which
are not included in the limited warranty are:

1. Correcting wiring problems in the electrical
circuit supplying the heat pump.

2. Resetting circuit breakers or other switches.

3. Adjusting or calibrating of thermostat.

To avoid misunderstandings at a later date,
carefully review these responsibilities with your
dealer or service company.

OPERATING INSTRUCTIONS

To Operate Your Heat Pump For Cooling —

1. Set the thermostat system switch to COOL
and the thermostat fan switch to AUTO. (See
Figure 1)

2. Set the ther mostat temperature selector to the
desired cooling temperature. The outdoor unit
fan, the indoor blower, and the compressor
will all cycle on and off to maintain the indoor
temperature at the desired cooling level.

NOTE: If the thermostat temperature level is
re-adjusted, or if the thermostat system switch
is re-positioned, the outdoor unit fan and the
compressor may not start immediately. A
protective timer circuit holds the compressor and

the outdoor fan off for approximately fi ve minutes
following a previous operation or the interruption
of the main electric power.

To Operate Your Heat Pump For Heating —

1. Set the thermostat system switch for HEAT
and the thermostat fan switch to AUTO. (See
Figure 1)

2. Set the thermostat temperature selector to the
desired heating temperature. The outdoor unit
fan, the indoor blower, and the compressor
will all cycle on and off to maintain the indoor
temperature at the desired heating level.

NOTE: If the thermostat temperature level is
re-adjusted, or if the thermostat system switch
is re-positioned, the outdoor unit fan and the
compressor may not start immediately. A
protective timer circuit holds the compressor and
the outdoor fan off for approximately fi ve minutes
following a previous operation or the interruption
of the main electrical power.

Emergency Heat — Some thermostats will
include a system switch position termed EM HT
or AUX HT, etc. This is a back-up heating mode
to be used only if there is a suspected problem.
With the system switch set to EM HT, etc., the
compressor and outdoor fan will be locked off and
supplemental heat (electric resistance heating)
will be used as a source of heat. Sustained
use of electric resistance heat in place of the
heat pump will result in an increase in electric
utility costs.

Defrost — During cold weather heating opera­tion, the outdoor unit will develop a coating of
snow and ice on the heat transfer coil. This is
normal and the unit will periodically defrost itself.
During the defrost cycle, the outdoor fan will stop,
while the compressor continues to run and heat
the outdoor coil, causing the snow and ice to melt.
During defrost, there may be some steam rise
from the outdoor unit as the warm coil causes
some melted frost to evaporate.

SECTION 2. INSTALLER INFORMATION

GENERAL

Pressures Within The System — This equip-

ment contains R-410A refrigerant under high
pressure. Installation or servicing should only
be performed by qualifi ed trained personnel
thoroughly familiar with this type equipment.

CAUTION:

This unit uses refrigerant R-410A. DO NOT
under any circumstances use any other re­frigerant besides R-410A in this unit. Use of
another refrigerant will damage this unit.

Read the following instructions completely
before performing the installation.

These instructions are for the use of qualifi ed
personnel specially trained and experienced
in the installation of this type of equipment
and related system components. Some states
require installation and service personnel to
be licensed. Unqualifi ed individuals should not
attempt to interpret these instructions or install
this equipment.

The single packaged heat pumps are designed
for outdoor installation only and can be readily
connected into the high static duct system of a
home. The only connections needed for instal­lation are the supply and return ducts, the line
voltage, and thermostat wiring. A complete heat
pump system typically consists of:

• Single Package Heat Pump

• Home Fittings Kit

• Unit Fittings Kit

• Thermostat

CAUTION:

To prevent personal injury and/or
equipment damage, check thermostat
manufacturer’s operation of fan relay
circuit when in EMER HEAT. When the
thermostat system switch is in the
EMER HEAT position, the thermostat
must energize the fan relay when the

fan switch is in the AUTO position.

The single package heat pump is completely
assembled, factory wired, and factory run tested.
The units are ready for easy and immediate
installation.

Use of components other than those speci­fi ed may invalidate ARI Certifi cation, Code
Agency Listing, and limited warranty on the air
conditioner.

PRE-INSTALLATION CHECK

Before any installation is attempted, 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.

The installer should comply with all local codes
and regulations which govern the installation
of this type of equipment. Local codes and
regulations take precedence over any recom­mendations contained in these instructions.
Consult local building codes and the National
Electrical Code (ANSI CI) for special installation
requirements.

The electrical supply should be checked to de­termine if adequate power is available. If there
is any question concerning the power supply,
contact the local power company.

Inspecting Equipment: All units are securely
packed at the time of shipment and, upon arrival,
should be carefully inspected for damage. Claims
for damage (apparent or concealed) should be
fi led immediately with the carrier.

INSTALLATION

1. SELECT THE BEST LOCATION FOR THE
HEAT PUMP UNIT

IMPORTANT: DO NOT PLACE UNIT UNDER
THE HOME.

• Select a solid, level position, preferably on a
concrete slab, slightly above the grade level,
and parallel to the home.

• 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 confi ned space.

• If practical, place the heat pump where it and
the ducts will be shaded from the afternoon
sun when the heat load is greatest.

• Try to select a site for the unit that is as close
as possible to the proposed return grille
location.

• Keep in mind that the length of the supply and
return ducts should be kept to a minimum with
no sharp radiused bends.

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. If unit has been
set on its side, restore to upright posi­tion and do not run for several hours.
Then run unit for a few seconds. Do this
three or four times with fi ve minutes

between runs.

a. Remove the bands from around the unit.

b. Unfold the top and bottom cap fl anges.

c. Carefully remove the top cap and tube.

3. CLEARANCES

Minimum clearances, as specifi ed in Figure 2,
MUST by maintained from adjacent structures
to provide room for proper servicing and air
circulation.

DUCT REQUIREMENTS

The supply duct system, including the number
and type of registers, will have much more ef­fect on the performance of an air conditioning
system then any other factor. The duct must be
suffi ciently large to conduct an adequate amount
of air to each register.

4. INSTALL THE RETURN AND SUPPLY AIR
FITTINGS ON THE UNIT

The supply and return fi ttings are included with
select models. If supplied, the duct fi ttings are
shipped in the supply duct. They attach to the unit
openings with a fl ange and bead arrangement,
secured with two sheet metal screws. Note: For
ease of access, install fi tting before positioning
unit in fi nal location.

SUPPLY DUCT

Position the supply duct collar, if supplied, so the
edge of the unit opening fi ts between the fl ange
and the bead. Overlap the collar ends keeping the
small screw holes underneath. Align the holes in
the crimped area and install one screw.

Note: It may be necessary to loosen the four
screws that hold the transition duct in order to
install the supply fi tting. Re-tighten when instal-

lation is complete.

Tap collar as necessary to ensure engagement
with unit opening and install second screw.
Tighten fi rst screw. Rotate collar clockwise so
joint is near three o’clock position.

RETURN DUCT

The 12” return duct is installed in the same
manner as the supply duct. If the duct has a 14”
return, follow these instructions.

Align the slots with the holes in the collar and
install two screws. Position the collar over the
opening and align the four notches in the collar
with the four dimples in the panel. Using self­drilling screws (10-16x.5) attach the collar to the
rear panel. On some models a 14” duct collar is

provided for the return duct.

5. LOCATING AND INSTALLING THE
RETURN AIR ASSEMBLY

an open area equal to or greater than the 12” x
20” grille furnished. The return air grille can be
placed in the wall of a closet and the air ducted
into the fi lter box through a boxed-in area at the
closet fl oor level. Make sure the fi lter is readily
accessible.

After determining the location of the return air
opening, start the installation from under the
home by cutting a small hole in the fi ber under­board to determine how the fl oor joist location
will affect cutting the opening needed for the box.
Floor joists generally are located on 16” centers,
leaving 14-3/8” between joists. After measuring
the return air box (approximately 12-1/4” x 20­1/4”), cut the hole through the fl oor so that the
box will fi t between the fl oor joists. Care should
be taken when cutting through carpeting to avoid
snags. In most installations it will be necessary to
cut a similar hole in the fi berboard directly under
the hole in the fl oor. However, if the fl oor 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.

Set the box into the opening and fasten with
screws or nails. Put the fi lter and return air
grille in place.

6. LOCATING AND INSTALLING THE
SUPPLY DAMPER(S)

When locating the supply damper(s), carefully
check fl oor joists and frame members that could
interfere with the installation of the damper
or fl exible duct. Ideally, the damper 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. To locate the center of the heat duct,
fi rst cut a small hole in the fi berboard below the
duct at the desired location. After locating the
duct center, cut a hole approximately 3/4” larger
than the damper opening in the fi berboard. Cut
a 9-1/8” x 13-1/8” hole in the duct and bend over

To avoid complications, locate and install the
return air assembly fi rst. The return air box with
grille and fi lter (Figure 4) should not be located
in heavy traffi c 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.
If desired, the return opening can be located
inside a closet with louvered doors that have

e. Once the inner duct is connected to the

proper fi tting, the insulation and plastic sleeve
should be pulled over the connection and
clamped.

f. For homes with multiple supply ducts or for

special applications, a Y fi tting is available to
divide the supply air so it can be ducted to
different areas of the home for more effi cient
cooling. Note: The Y fi tting should be insulated
for maximum performance.

Blower Speed For optimum system performance
and comfort, it may be necessary to change
the factory set speed. See Figure 8 for factory
settings. NOTE: The 2 Ton blower motor has
three speed taps, Low, Med, High. The 2.5 ton
standard blower motor has two speeds, Low and
High. The 3, 3.5 and 4 ton models have High
Effi ciency Motors with 5 speed taps.

If Standard Motor (2 and 2.5 Ton)

1. Disconnect all electrical power to the unit
and remove the service panel.

2. The blower speed is preset at the factory
for operation at the same speed for
heating and cooling.

3. Place the desired blower speed lead on
the “COM” terminal of the blower relay.
Use another wire tie (fi eld supplied) to
bundle the remaining motor lead up and
out of the way.

If High Effi ciency Motor (3, 3.5, and 4 Ton)

1. Disconnect all electrical power to the unit

and remove the service panel.

2. Locate the orange and red wires

terminated to the blower motor. The
orange wire controls the cooling
operation and the red wire controls the
heating operation.

3. Verify the required speed from the airfl ow

data found in Figure 8. Place appropriate
wire on the appropriate motor speed tap
for the required airfl ow.

CAUTION:

To avoid personal injury or property
damage, make certain that the motor
leads cannot come into contact with
any uninsulated metal components
of the unit.

Check all factory wiring per the unit wiring
diagram and inspect the factory wiring connec­tions to be sure none loosened during shipping
or installation.

7

CONDENSATE DRAIN

A 3/4” condensate fi tting extends out of the side
of the unit. The drain trap, shipped in the electrical
compartment, must be installed to prevent water
from collecting inside the unit. Thread the elbow
provided with the unit into the drain connection
until hand tight. Install the trap into the fi tting
making sure it is level. Route the condensate
from the trap to a suitable drain. Any tubing or
hose connected must have the outlet below trap
level for proper drainage.

b. Connect the control wires to the defrost board

and blower relay wire. (See Figure 10.)

2. OVERCURRENT PROTECTION

In general, the best fuse or breaker for any
heat pump is the smallest size that will permit
the equipment to run under normal use and
service without nuisance trips. Such a device,
sized properly, gives maximum equipment
protection. The principal reason for specifying

a

time delay type is to prevent nuisance trips

when the unit starts.

WARNING:

Turn off electrical power before servic­ing controls. Severe electrical shock
may result unless power is turned off.
Unit must be installed in compliance
with the National Electrical Code (NEC)
and local codes.

ELECTRICAL CONNECTIONS

1. ELECTRICAL SERVICE

High Voltage

a. Install a branch circuit disconnect of adequate

size per NEC. Locate the disconnect within
sight of the unit.

b. Extend leads through power wiring hole

provided. Connect L1 and L2 directly to the
contactor. (See Figure 9.)

c. Ground the heat pump unit using the green

grounding screw provided in the control
panel.

In the event that a fuse does blow or a breaker
trips, always determine the reason. Do not arbi­trarily put in a larger fuse or breaker and do not,
in any case, exceed the maximum size listed on
the data label of the unit.

3. LOCATING THE THERMOSTAT

Locate the thermostat away from drafts and
slamming doors and place it where there is a free
fl ow of air. Mount on an inside wall approximately
fi ve feet from the fl oor.

Do not locate near a lamp, kitchen range, direct
sunlight, or in line with air fl ow from supply
registers.

Connect the Heat-Cool Thermostat: 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.

Low Voltage

a. Route 24v control wires through the sealing

grommet near the power entrance. (See
Figure 9.)

installed:Connect the thermostat to the orange

low voltage wire and the E terminal on the
defrost board (See Figure 10 page 9). See the
thermostat instructions for details on setting
the outdoor thermostat.

4. 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
indicating the coil temperature is low enough
to start accumulating frost. The board has
interval settings of 30 minutes, 60 minutes, 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.

5. OUTDOOR THERMOSTAT (Factory Option)

The outdoor thermostat prevents the electrical
auxiliary heat (if used) from operating above
a desired set point. The factory temperature
setting is at 40°F.

6. ELECTRIC HEAT PACKAGE (OPTIONAL)

The heat pumps are shipped without an
auxiliary electric heat kit installed. If electric
heat is desired, an accessory Heater Kit must
be fi eld installed. See Specifi cations Sheet for
available kits and their application.

• Select the correct size heat package for the
installation.

• Follow installation instructions provided with
each heater kit.

• Installation is most easily accomplished before
making duct or electrical connections.

• Refer to fi gure 8 for blower speeds.

SYSTEM OPERATION

1. PRE-START CHECK LIST

The following check list should be observed prior
to starting the unit.

Is the unit level? It should be level or slightly

slanted toward the drain for proper conden­sate drainage.

Is the unit installed with the proper clear-

ances (See Figure 2)?

10

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?

2. START-UP PROCEDURE

The control circuit consists of an anti-short cycle
timer that will not let compressor re-start before
fi ve (5) minutes have elapsed.

Set the thermostat system switch to OFF, and
the thermostat fan switch to AUTO. Apply power
at the disconnect switch and check the system
operations:

a. Air Circulation — Leave the thermostat

system switch at OFF, and set the thermostat
fan switch to ON. Blower should run
continuously. Check the air delivery at the
supply registers and adjust register openings
for balanced air distribution. Examine
ductwork for leaks or obstruction if insuffi cient
air is detected.

Set the thermostat fan switch to AUTO; the blower
should stop running.

b. System Heating — Set the thermostat

system switch to HEAT and set the thermostat
fan switch to AUTO. Position the thermostat
temperature selector above the existing room
temperature and check for the discharge of
warm air at the supply registers.

c. System Cooling — Set the thermostat

system switch to COOL and set the thermostat
fan switch to AUTO. Position 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.

d. 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 de-energizes.
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.

e. Emergency Heat — (Available only when

Electric heat is supplied) Set the thermostat
system switch to EM HT and set the thermostat
fan switch to either AUTO (intermittent air) or
to ON (continuous air). Position the thermostat
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 fan switch setting.

Refrigerant Charging — Packaged Air
Conditioners are fully charged with R410-A
refrigerant at the factory. The system refrigerant
charge can be checked and adjusted by removing
the compressor cover panel and attaching gauge
lines which have a “schrader” depression device
present to activate the valve. Draw a vacuum
on gauge lines to remove air before attaching
them to the service ports on the unit. Refrigerant
charging must be done by qualifi ed personnel
familiar with safe and environmentally responsible

refrigerant handling procedures.

DEFROST CONTROL BOARD OPERATION
AND TESTING

1. Terminals “R”-”C” must have 24±V present
between them in order for the time delay and
defrost sequences to be operational.

2. Jumper the “T2”-”DFT” test pins. This will
indicate to the board that the defrost T-stat
is closed(if the compressor is running).
Defrost T-stat is closed at 32° or below and
is open at 68° or above. But it’s state is
unknown if the temperature is between 32°F
and 68°F. The defrost thermostat tells the
board whether a defrost cycle needs to be
started or terminated. 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, turn on the
compressor and raise 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.

3. Defrost board speed-up. With compressor
running in heat mode, next jump the “Test”
pin to “C” on terminal strip. This will initiate
a defrost test in 5, 10 or 15 seconds (This
is determined by the 30, 60 or 90 minute
defrost pin settings. The factory setting will

be 30 minutes). Note that this will bypass the
compressor off delay when the unit goes into
defrost test and if left in defrost test, the delay
will be bypassed when the test is terminated
by the processor. If the jumper is removed
before the test is over the processor will
perform the remainder of a normal defrost.
See step 2 above.

4. Remove the jumpers.

Note: The delay/no-delay pin concerns compressor
operation during defrosts. The default setting is
delay. Reciprocating compressors should only
use this setting in conjunction with an approved
hard start kit. 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. To switch from no-delay to delay
remove the pin from the “no-delay” pin location
and shift it to the “delay” pin location.

Speed up changes:

Manually initiating a defrost will cause the

compressor to run continually when entering
defrost.

Normal defrost operation:

To test normal defrost operation when the
temperature is above 35°F, jumper “R” to
“DFT” on the 624656 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 become
inoperable.

Defrost Test Procedure for 624656

1. Jumper “T2” to “DFT” at the test terminals.

2. With unit running in heat mode, short the
“TEST” terminal to the common terminal near
it. This will speed up the board and cause
it to enter defrost mode in 5/10/15 seconds
depending on the defrost time selection.
Compressor delay will not function during
speed-up.

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 home
owner preference.
