heat pump products available today. To assure its dependabil-
ity, spend just a few minutes with this booklet now. Learn about
the operation of your heat pump, and the small amount of
maintenance it takes to keep it operating at its peak efficiency.
With minimal care, your new heat pump will provide you and
your family with year-round home comfort--both now and
l\)r years to come.
SAFETY CONSIDERATIONS
Recognize safety int\_rmation. This is the safety-alert symbol
z_. When you see this symbol on the unit and in instructions
or manuals, be alert to the potential l\_r 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 woMd result in minor
personal injury or product and property damage. NOTE is used
to highlight suggestions that will result in enhanced installation,
reliability, or operation.
Improper installation, adjustment, alteration, ser-
vice, maintenance, or use can cause explosion,
fire, electrical shock, or other conditions which
may cause personal injury or property damage.
Consult a qualified installer, service agency, or
your distributor or branch for information or as-
sistance. The qualified installer or service agency
must use factory-authorized kits or accessories
when modifying this product.

To prevent personal injury, death, or property
damage, read and follow all instructions and warn-
ings, including labels shipped with or attached to
unit before operating your new heat pump.
YOUR COMFORT SYSTEM
Identifying Your System
Take the time to familiarize yonrself with the type of system
you have. This knowledge will be of use in understanding the
basic operation of your new heat pump.
The type of heat pump you have purchased 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. (See Fig. 1.)
Each unit has a rating plate affixed to it which provides neces-
sary int\_rmation l\)r specific identification of a unit.You should
familiarize yourself with the product, model, and serial num-
bers listed on each rating plate. Record them t\_r future refer-
ence on the last page of this booklet.
IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the l\_llowing facts:
• Your heat pump system should never be operated without a
clean air filter properly installed. Plan to inspect the filter peri-
odically. A clogged air filter will increase operating costs and
shorten the life of the unit.
• Supply-air and return-air registers should not be blocked.
Drapes, furniture, and toys are some of the items commonly
l\mnd obstructing registers. Restricted airflow lessens the
unit's efficiency and life span.
• The outdoor unit must have unrestricted airflow. Do not cov-
erthe unit, lean anything 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.
• 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--t\_r instance, switching
the electrical supply power ON and OFF--may cause damage
to the unit.
• During heating, increasing the thermostat setting more than
2 degrees may cause the supplemental heaters to be turned on
to satisfy the thermostat. Needless use of the supplementary
heat reduces potential energy savings.
• You may find that you can maintain greater personal com-
l\m by running the fan continuously. Air pockets can t\_rm due
to the structure of the house, placement of registers, etc. These
air pockets may be too cool or warm l\_r your liking. Continu-
ous fan operation minimizes any temperature differences.
Also, systems equipped with electronic or mechanical air
cleaners and/or humidifiers offer the added benefits of having
the air continuously cleaned year-round and humidified during
the winter season.
• A system equipped with a heat or enelgy recovery ventilator
offers the advantage of exhausting stale air from the home and
allowing fresh air in from the outdoors while minimizing heat loss.
