WELCOME TO EFFICIENT
YEAR-ROUND COMFORT
Congratulations on your excellent choice and sound invest­
ment in year-round home comfort!
Your new heat pump represents both the latest in engineering
development and the culmination of many years of experience
from one of the most reputable manufacturers of comfort
systems.
Your new unit is among the most energy-efficient and reliable
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 for
years to come.
A WARNING
Improper installation, adjustment, alteration, service,
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 agency must use fac­
tory-authorized kits or accessories when modifying this
product.
A WARNING
To prevent personal injury, death, or property damage, be­
fore operating your new heat pump, read and follow all in­
structions and warnings, including labels shipped with or
attached to unit.
YOUR COMFORT SYSTEM
Identifying Your System
Thke the time to familiarize yourself with the type of system
you have. This knowledge will be of use in understanding the
basic operation of your new heat pump.
The split-system type has an indoor and an outdoor unit, each
of which contains a coil. These units are interconnected by re­
frigerant tubes, as shown in Fig. 1.
Each unit has a rating plate affixed to it. A rating plate provides
necessary information for specific identification of a unit. You
should familiarize yourself with the product, model, and serial
numbers listed on each rating plate.
IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the following 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
found obstructing grilles. Restricted airflow lessens the unit’s
efficiency and life span.
• The outdoor unit must have unrestricted airflow. Do not
cover the unit, lean anything against it, or stand upon it. Do not
allow grass clippings, leaves, or other debris to accumulate
around or on top of the unit. Maintain a 12-in. minimum clear­
ance 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. Attempting to control the system by
other means—for instance, switching the electrical supply
power ON and OFF-—may cause damage to the unit.
• Thermostat “jiggling” causes rapid-cycling, which is poten­
tially damaging to the compressor. Do not move the tempera­
ture selector on the thermostat for any reason for at least 5
minutes after the compressor has shut off.
• During the heating season, never increase the indoor thermo­
stat setting more than 1 or 2-degree increments. If larger adjust­
ments are made, the supplementary heating source will be
turned on automatically. Needless use of the supplementary
heat reduces potential energy savings.
• You may find that you can maintain greater 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. Continuous fan
operation minimizes any temperature differences. Also, sys­
tems equipped with electronic air cleaners and/or humidifiers
offer the added benefits of having the air continuously cleaned
year-round, and humidified during the winter season.
• Your heat pump will remove humidity from your home dur­
ing the cooling season. After a few minutes of operation, you
should be able to see water trickle from the condensate drain of
the cooling coil. Check this occasionally to be sure the drain
system is not clogged. Of course, don’t expect to see much drain­
age if you live in a very dry environment.
• During the heating cycle, air from your registers may seem
cooler than you might first expect. This is because the air is be­
ing delivered at a higher velocity and a more constant flow than
air supplied by a conventional furnace. Also, your heat pump
supplies air at 85 to 90°F instead of in sudden bursts of hot air
as with a conventional furnace. The air may feel cool because it
is slightly less than your body temperature. However, it is suffi­
ciently warm to keep you comfortable.
• Ice or frost will tend to form on the outdoor coil during the
winter heating operation. Your heat pump is designed to auto­
matically melt the ice. When in this defrost cycle, it is normal
