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 isa unique, all weather comfort-
control system appliance. The basic operation
of the heating/cooling system is described and
illustrated on page 1of this man ual.The surprising
fact that heat exists inair 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 flow of the heat-
absorbing refrigerant to become an energy-
efficient, central air conditioner.

SECTION 1. OWNER INFORMATION
SYSTEM SWITCH
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 efficient 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.
The manufacturer warrants the heat pump to be
free from defects in workmanship or material for
a period of one year. A warranty certificate with
full details is included with the heat pump.
However, we 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 specific 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.

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 five
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 desi red heating tem peratu re. The outdoor
unit fan, the indoor blower, and the
compressor will all cycle on and off to
maintain the indoor temperature at the desi red
heating level.
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 thermostat 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 five
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
orAUX 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

shipped in the supply duct. They attach to the
unit openings with a flange and bead
arrangement, secured with two sheet metal
screws. Note: For ease of access, install fitting
before positioning unit infinal location.
SUPPLY DUCT
Position the supply duct collar, if supplied, so the
edge of the unit opening fits between the flange
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 fitting. Re-tighten when
installation is complete.
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 fewseconds.
Do this three or four times with five
minutes between runs.
a. Remove the bands from around the unit.
b. Unfold the top and bottom cap flanges.
c. Carefully remove the top cap and tube.
3. INSTALL THE RETURN AND SUPPLY
AiR FiTTiNGS ON THE UNIT
The supply and return fittings are included with
select models. If supplied, the duct fittings are
Tap collar as necessary to ensure engagement
with unit opening and install second screw.
Tighten first 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 inthe collar
with the four dimples in the panel. Using self-
drilling screws (10-16x.5) attach the collar to the
rear panel. On some models a 14" duct collar is
provided for the return duct.
4. LOCATING AND INSTALLING THE
RETURN AiR ASSEMBLY
To avoid complications, locate and install the
return air assembly first. The return air box with
grille and filter (Figure 4) 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. If desired, the return opening can be

have an open area equal to or greater than the
12"x 20" grille furnished. The return air grille can
be placed inthe wall of a closet and the air ducted
into the filter box through a boxed-in area at the
closet floor level. Make sure the filter is readily
accessible.
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 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,
first cut a small hole in the fiberboard below the
duct at the desired location. After locating the
duct center, cut a hole approximately 3/4" larger
than the damper opening inthe fiberboard. Cut
a 9-1/8" x 13-1/8" hole inthe duct and bend over
all tabs flat on the inside of the heat duct. After
inserting the damper into the duct, bend over all
tabs flat on the inside of the heat duct. Seal the
opening between the fiberboard and damper or
flexible duct.
DUCTING SYSTEM
After determining the location of the return air
opening, start the installation from under the
home bycutting asmall hole inthe fiber underboard
to determine how the floor joist location will affect
cutting the opening needed for the box. Floor
joists gene rally are located on 16"centers, leaving
14-3/8" between joists. After measuring the
return air box (approximately 12-1/4" 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. 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.
Set the box into the opening and fasten with
screws or nails. Put the filter and return air grille
in place.

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.
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.
Connect the low voltage wires to the respective
terminals on the thermostat base. See thermo-
stat instruction sheet for more detailed informa-
tion. (See Figure 10).
if two stage heating is desired, an optional
outdoor thermostat may be installed:
Connect the thermostat to the orange low volt-
age wire and the W terminal on the indoor
thermostat base (See Figure 10). See the ther-
mostat 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 amoist 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
3. LOCATING THE THERMOSTAT
Locate the thermostat away from drafts and
slamming doors and place it where there is a free
flow of air. Mount on an inside wall approximately
five feet from the floor.
Do not locate near a lamp, kitchen range, direct
sunlight, or in line with air flow 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 eq uipped
The outdoor thermostat prevents the electrical
auxiliary heat (if used) from operating above a
desired set point. Selection of the set point is
determined from the building design heat load.
The thermostat is adjustable from 45°F to 0°F.
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 field
installed. See Specifications Sheet for available
kits and their application.

2. START=UPPROCEDURE
The control circuit consists of an anti-short cycle
timer that will not let compressor re-start before
five (5) minutes have elapsed.
Set the thermostat system switch to OFF, and
the thermostat fan switch toAUTO. 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 ifinsufficient
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 the rmostat
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.
