This Heat Pump has been specially developed and built as a heat pump
to meet the dual needs of heating and cooling. It's not just an air condi-
tioner with extra parts. That's why you can rely on efficient, trouble-free
operation.
Your system is fully automatic. Set the thermostat and forget it. And it's
automatically protected from damage by voltage fluctuations or exces-
sive heating or cooling demands.
Your split system heat pump consists of two units - one installed out-
doors and one installed indoors. The indoor unit may be installed in a
basement, attic, or crawl space.
HOW YOUR HEAT PUMP WORKS
If your hand is wet and you blow on it, it feels coot because some of the
moisture is evaporating and becoming a vapor. This process requires
heat. The heat is being taken from your hand, so your hand feels cool.
That's what happens with a heat pump. During the cooling cycle, your
system will remove heat and humidity from your home and will transfer
this heat to the outdoor air.
During the heating cycle, your system will remove heat and humidity
from the outdoor air and will transfer this heat to your home. This is pos-
sible because even 0°F outdoor air contains a great deal of heat.
Remember that your heat pump doesn't generate much heat, it merely
transfers it from one place to another.
SYSTEM OPERATION
Your thermostat puts full control of the comfort level in your home at
your fingertips. DO NOT switch your thermostat rapidly "On" and "Off"
or between "Heat" to "Cool" This could damage your equipment. Always
allow at least 5 minutes between changes.
SETTING THE THERMOSTAT
Although thermostats may vary widely in appearance, they are all
designed to perform the same basic function: to control the operation of
your air conditioning or heat pump system. Regardless of size or shape,
each thermostat wilI feature a temperature indicator; a dial, arm, or
push button for selection of the desired temperature; a fan switch to
choose the indoor fan operation; and a comfort switch for you to select
the system mode of operation.
Only approved thermostats have been tested and are fully compatible
with this equipment. Please be aware that many different thermostats
operate on batteries or "power stealing" principals. These types of ther-
mostats can not be supported as trouble free when used with this producL
A complete operating instruction is provided by the manufacturer for
each thermostat. Familiarize yourself with its proper operation to obtain
the maximum comfort with minimum energy consumption.
If your system has been designed to allow both cooling and heating
operation, you may have either a manual change-over type, or a pro-
grammable electronic type thermostat.
Manual change-over simply means that the comfort switch must be
manually positioned every time you wish to switch from the cooling to
heating or heating to cooling modes of operation.
The computerized electronic thermostat is actually a sophisticated elec-
tronic version of a manual change-over type. This thermostat includes
features which allow "set-back" temperature variations for periods of
sleep, or while you are away during the day, and means energy savings
for you. The thermostat also features a digital clock.

ACAUTION
The main power to the system must be kept "ON'at all times to
prevent damage to the outdoor unit compressor. If necessary,
the thermostat control switch should be used to turn the system
"OFF't Should the main power be disconnected or interrupted
for 8 hours or longer, DO NOT attempt to start the system for 8
hours after the power has been restored to the outdoor unit. If
heat is needed during this 8 hour period, use emergency heat.
Fan Operation Selection
A multi-position fan switch allows you to choose the type of fan opera-
tion of the indoor fan.
AUTO - With the thermostat fan switch set to "AUTO", the fan will run
intermittently as required for either heating or cooling. This position will
provide the lowest operating cost.
ON - If the fan switch is set to "ON", the indoor fan will not shut off. How-
ever, the system will still operate as required by room temperatures.
This provides continuous air filtering and more even temperature distri-
bution throughout the house, which is especially useful in houses with
basements.
Usually during spring and fall, when neither heating nor cooling is
required, you may want to run only the fan to ventilate, circulate, and fil-
ter the air in your home or building. Set the comfort control switch to
"OFF" and the fan switch to "ON". Be sure to return the switches to their
original positions for normal operation.
Heating Cycle
With the thermostat in the heating position, and the outdoor tempera-
ture in the range of 20 to 30 °or below, the outdoor unit will generally run
100%of the time.
All systems can be equipped with balance point control to provide even
more efficient operation. This control will prevent the electric heater
from being energized when the outdoor air is above some predeter-
mined temperature setting (0 to 45°F). At higher temperatures, your
system will provide all the heat your home will ever need. At lower tem-
peratures, the auxiliary heat will be energized to keep your home com-
fortable.
When the outdoor air is cool and moist, frost may form on the surface of
your outdoor coil. When this frost builds to a certain point, your system
will switch to a defrost cycle. Although you may feel cooler air coming
from your registers, DO NOT adjust your thermostat. The frost will melt
quickly, and your system will return to normal operation automatically.
Cooling Cycle
Switch your thermostat to cool.Select a comfortable thermostat temper-
ature setting, typically between 75 and 80 ° . Comfort sensations vary
with individuals. The lower the indoor temperature desired, the greater
will be the number of hours your unit must operate.
Set your thermostat 2 or 3°F below normal several hours before enter-
taining large groups during hot weather. People give off considerable
heat and moisture.
On an extremely hot day, the indoor temperature may rise 3 to 6°F
above the thermostat setting. Properly selected equipment does not
have the capacity to maintain a constant indoor temperature during the
peak load. Over-sizing your system to handle this peak load is not prac-
tical because the oversized system would operate much less efficiently
at all other conditions.
TO MAXIMIZE OPERATING EFFICIENCY
HEATING CONSERVATION
For the most efficient operation, keep storm windows and doors closed
all year long. They not only help insulate against heat and cold, but they
also keep out dirt, pollen and noise.
Closing drapes at night, keeping fireplace dampers closed when not in
use, and running exhaust fans only when necessary will help you to
retain the air you have already paid to heat.
Keep lamps, televisions, or other heat producing sources away from the
thermostat. The thermostat will sense this extra heat and will not be
able to maintain the inside temperature to the desired comfort level.
COOLING CONSERVATION
To comfortably cool your home, your heat pump must remove both heat
and humidity. Don't turn your system off even though you will be away
all day. On a hot day, your system may have to operate between 8 to 12
hours to reduce the temperature in your home to a normal comfort level.
Keep windows closed after sundown. While the outdoor temperature at
night may be lower than indoors, the air is generally loaded with mois-
ture which is soaked up by furniture, carpets, and fabrics. This moisture
must be removed when you restart your system.
The hotter the outside temperature, the greater the load on your sys-
tem. Therefore do not be alarmed when your system continues to run
after the sun has set on a hot day. Heat is stored in your outside walls
during the day and will continue to flow into your home for several hours
after sunset.
Use your kitchen exhaust fan when cooking. One surface burner on
"HIGH" requires one ton of cooling. Turn on your bathroom exhaust fan
while showering to remove humidity. However, exhaust fans should not
be run excessively. It would decrease efficiency by removing condi-
tioned air.
You can also help your system in the summer by closing drapes or
blinds and by lowering awnings on windows that get direct sunlight.
CARE OF SYSTEM
IMPORTANT: The Owner/user should not attempt to disassemble the
equipment nor perform the periodic maintenance unless they are expe-
rienced and qualified to do so.
A periodic inspection, cleaning, lubrication and adjustment of your heat
pump is available from your dealer. Be sure to ask him about this ser-
vice.
For those who prefer to do-it-yourself, follow the instructions below to
care for your system.
COIL CARE
Keep the outdoor unit free of loose snow, foliage, grass clippings,
leaves, paper, and any other material which could restrict the proper air
flow in and out of the unit. The coil may be vacuumed to remove any
debris from between the fins. However, don't knock ice off the outdoor
unit's coil surface following an ice or severe snowstorm. The blows
could mash the coil fins shut (blocking air passage), or break the refrig-
erant tubing allowing the refrigerant to escape.
If the coil becomes excessively dirty, turn the main disconnect switch to
"OFF" and wash the coil with your garden hose. Avoid getting water into
the fan motor and control box. Flush dirt from base pan after cleaning
the coil.
CARE OF FAN MOTORS
Some fan motors are provided with lubrication ports. Inspect your
indoor and outdoor units to determine whether or not lubrication ports
are provided.

FILTER CARE
Inspect the air filter(s) at least once a month. If they are dirty, wash
reusable filters with a mild detergent per manufacturer's recommenda-
tions. Replace disposable filters with new filters.
Install the clean filters with "air flow" arrow in the same direction as the
air flow in your duct. Filters should be clean to assure maximum effi-
ciency and adequate air circulation. Drapes, furniture or other obstruc-
tions blocking your supply and return air grilles will also decrease
efficiency.
OUTDOOR UNIT FINISH
If you wish to maintain the finish of the outdoor unit, it can be polished
with car wax. It is recommended the unit be cleaned with soap and
water prior to waxing.
If your system is an Add-on type, (installed in conjunction with a stan-
dard furnace) inspect your furnace blower motor and care for it in the
same way.

2. Leave on emergency heat for at least 8 hours after electrical
power is re-established if the power was off more than 8 hours.
3. Switch thermostat back to heating or auto.
Cooling Season
1. Switch thermostat to OFF position.
2. Do not switch to cooling or auto until electrical power has been re-
established for 8 hours if the power was off more than 8 hours.
SERVICE CALLS
There are a few instances where you can avoid unnecessary service
calls. (See Troubleshooting Guide above). Some models provide fault
codes. The flashing light on the system thermostat is capable of provid-
ing you with time and money saving information. The fault code num-
bers listed can be handled by taking the corrective action indicated. Call
qualified service person if displaying fault code numbers not listed.
PARTS INFORMATION
Replacement parts are available from local contractor/dealers or the
nearest distribution center.
CHARACTERISTICS OF HEAT PUMPS
A CONSTANT HEAT
Heat pumps have a noticeable cooler supply air temperature than fur-
naces. The common practice of over-sizing furnaces contributes to an
"off-and-on again" operation with short blasts of hot supply air. The heat
pump system is sized more closely to the heating needs of your home.
Heat is supplied at a lower temperature over a longer period of time to
provide a more constant heat, and it may give you the impression that
your system "never stops running".
WATER RUN-OFF
During the heating cycle, in mild weather you may notice water running
off the outdoor coil. Moisture from the air is condensed on the outside
surface of the coil where it gathers and runs off. No need for alarm, your
unit has not sprung a leak!
OUTDOOR COIL DEFROSTING
At certain outdoor conditions (low temperature, high humidity), frost
may build up on the coil of the outdoor unit. In order to maintain heating
efficiency, the system will automatically defrost itself. Steam rising from
the outdoor unit is normal and is an indication of proper operation. The
vapor cloud will only last for a few minutes. When the defrost cycle is
completed, the system will automatically switch back to heating. Auxil-
iary heat is automatically energized to maintain comfort during defrost.
