Single Package Heat Pump
INTRODUCTION
Your heat pump is a unique, all weather com-
fort-control system appliance. The basic op-
eration of the heating/cooling system is de-
scribed on page 2 of this manual. The surpris-
ing fact that heat exists in air even at below-
freezingtemperaturesisactuallythebasiclaw
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 approxi-
mately2to3unitsofheatenergypereachunit
of electrical energy used, as compared to a
maximum of only 1 unit of heat energy pro-
duced with conventional heating systems.
During the cooling season, the heat pump
reverses the flow of the heat-absorbing refrig-
erant to become an energy-efficient, central
air conditioner.
Single Package Heat Pump

2
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.
Duringthewintermonths,aheatpumpperforms
like an air conditioner running 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.
OPERATINGINSTRUCTIONS
To Operate Your Heat Pump in 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
thedesiredcoolingtemperature.Theoutdoor
unitfan,theindoorblower,andthecompressor
will all cycle on and off to maintain the indoor
temperature at the desired cooling level.
To Shut Off Air Conditioner
1. Turn the system switch to "Heat" or "Off."
2. Turn the thermostat to the desired heating
temperature setting.
To Operate Your Heat Pump For Heating —
1. Set the thermostat system switch to HEAT
and the thermostat fan switch to AUTO.
(See Figure 1)
2. Set the thermostat temperature selector to
thedesiredheatingtemperature.Theoutdoor
unitfan,theindoorblower,andthecompressor
will all cycle on and off to maintain the indoor
temperature at the desired heating level.
Defrost — During cold weather heating
operation,theoutdoorunitwilldevelopacoating
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
willstop, while the compressor continuesto run
andheattheoutdoorcoil,causingthesnowand
ice to melt. During defrost, there may be some
steam rising from the outdoor unit as the warm
coil causes some melted frost to evaporate.
BEFORE YOU CALL A SERVICEMAN
Check your system at the start of each air
conditioning season. Make sure it's working
correctly, clean or change filters and make any
needed adjustments.
In addition, follow these simple rules:
1. Never run your system without a filter. If
youdo, the coolingcoils will collect dirt and
may become clogged.
2. Leave thermostat set at the comfort level
you wish. Let it control the operation of the
air conditioning system. If room temp is
unsatisfactory, gradually raise the setting
until comfort is restored.
3. It takes longer for an air conditioner to cool
your dwelling than it does for your furnace
to heat it. So . . . don't turn the unit on and
expect an immediate drop in temperature.
Ifyourhomeishotandhumid,thetempera-
ture will drop slowly.
4. Check your filters every 30 days to see if
they are dirty. To keep them clean, use a
mild solution of detergent and water on
washable types. Replace non washable
filters.
5. Keep your outdoor condenser coil clean.
(You can hose it down when it gets dirty.)
If your air conditioner isn't working:
1. Make sure the fuses are not blown or that
your circuit breakers are on.

2. See that your thermostat is set at the
desiredtemperatureandthatyoursystem's
switch is on "Cool."
3. For best air flow, make sure your return
grille is not covered and that the filter is
clean.
4. Check the outdoor condenser coil and
make sure it is clean and not clogged with
grass or leaves.
Ifyour airconditioner stillisn't working,call your
nearest distributor.

2. OVERCURRENT PROTECTION
In general, the best fuse or breaker for any air
conditioner 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 pro-
tection. 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.
3. HEAT-COOL THERMOSTAT OPERATION
Heat-Cool Thermostat: Your thermostat
should be located on an inside wall approxi-
mately five feet from the floor away from drafts
and doors. Do not locate lamps or other objects
near the thermostat which could affect its op-
eration or block a free flow of air.
The heat-cool thermostat is equipped with a
system HEAT-COOL switch, which provides a
positive means of preventing simultaneous
operationoftheheatingandcoolingmode. The
thermostat is also equipped with an AUTO-ON
fan switch which allows the home owner to
operate the indoor blower when air circulation
is desired.
4. DEFROST CYCLE CONTROL
The defrost cycle is initiated via a signal from a
low pressure switch located in the outdoor side
return gas tubing. This signal indicates the coil
pressure has fallen low enough due to the build
up of frost. The defrost cycle will terminate via
atemperatureswitchlocatedontheoutdoorcoil
after the frost has been cleared.
5. OUTDOOR THERMOSTAT
Theoutdoorthermostat(locatedatthetopofthe
controlpanel)preventstheauxiliaryheatsource
(gas or electric) from operating above a certain
setpoint. Thethermostat is non-adjustablewith
a factory setting of 40°F.
SYSTEMOPERATION
1. PRE-START CHECK LIST
The following check list should be observed
prior to starting the unit.
Istheunitlevel? Itshouldbelevelorslightly
slanted toward the drain for proper con-
densate drainage.
Is there free air flow to and from the con-
denser? A one foot clearance around the
coil, and six foot clearance above the fan?
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 thermostat wired correctly? Is it
installed in a proper location?
2. START-UP PROCEDURE
