SAFETY
CONSIDERATIONS
Recognize safety information. This is
the safety-alert symbol
. When you
see this symbol on the unit and in
instructions or manuals, be alert to the
potential for personal injury.
Understand the signal words DANGER,
WARNING, and CAUTION. These
words are used with the safety-alert
symbol. DANGER identifies the most
serious hazards which
will
result in
severe personal injury or death.
WARNING signifies hazards which
could
result in personal injury or
death. CAUTION is used to identify
unsafe practices which
would
result in
minor personal injury or product and
property damage.
WARNING
Improper installation, adjust-
ment, alteration, service, main-
tenance or use can cause
explosion, fire, electrical shock,
or other conditions which may
cause personal injury or prop-
erty damage. Consult a quali-
fied installer, service agency or
your distributor or branch for
information or assistance. The
qualified installer or agency
must use factory-authorized
kits or accessories when modi-
fying this product.

YOUR COMFORT
SYSTEM
Identifying Your System
Take the time to get to know the type of
system you have. This will be useful in
understanding the basic operation of your
new heat pump.
The type of heat pump you have pur-
chased is a split system. The split-system
type has an indoor and an outdoor unit,
each of which contains a coil. These units
are interconnected by refrigerant tubes,
as shown in Fig. 1.
Each unit has a rating plate affixed to it.
A rating plate provides necessary infor-
mation for specific identification of a
unit. You should familiarize yourself with
the product, model, and serial numbers
listed on each rating plate. Record them
for future reference on the last page of
this booklet.
IMPORTANT FACTS
To better protect your investment and to
eliminate unnecessary service calls, famil-
iarize yourself with the following facts:
Keep Filter Clean
Your heat pump system should never be
operated without a clean air filter properly
installed. Plan to inspect the filter once per
month. A clogged air filter will increase
operating costs and shorten the life of the
unit.
Do Not Block Registers
Supply-air and return-air registers should
not be blocked. Drapes, furniture, and
toys are some of the items commonly
found obstructing registers. Restricted air-
flow lessens the unit’s efficiency and
shortens its life span.
Do Not Cover or Block
Outdoor Unit
The outdoor unit must have unrestricted
airflow. Do not cover the unit, lean any-
thing against it, or stand on it. Do not
allow grass clippings, leaves, or other
debris to accumulate around or on top of
the unit. Maintain a 12-in. minimum
clearance between the outdoor unit and
tall grass, vines, shrubs, etc.
Get To Know Your Thermostat
Your multipurpose indoor thermostat is
the control center for your heat pump
system. You should familiarize yourself
with its proper operation. (See Fig. 2
and 3.) Attempting to control the system
by other means—for instance, switch-
ing the electrical supply power on and
off—may damage the unit.
During the heating season, never increase
the indoor thermostat setting more than
1- or 2-degree increments. If larger
adjustments are made, the supplementary
heating source will be turned on automat-
ically. Needless use of the supplementary
heat reduces potential energy savings.
Continuous Fan
You may find that you can maintain great-
er personal comfort by running the fan
continuously. Air pockets can form due to
the structure of the house, placement of
registers, etc. These air pockets may be
too cool or warm for your liking. Contin-
uous fan operation minimizes any temper-
ature differences.
WARNING
To prevent personal injury,
death, or property damage,
read and follow all instructions
and warnings, including labels
shipped with or attached to
unit before operating your new
heat pump.
