YOUR COMFORT SYSTEM
Identifying Your System
Take 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 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 information for specific identification of a unit. You should
familiarize yourself with the product, model, and serial num-
bers listed on each rating plate. Record them for 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 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 registers. Restricted airflow lessens the
unit's efficiency and life span.
• The outdoor unit must have unrestricted airflow. Do not cov-
er the 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. Attempting to control the system by
other means—for 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-
fort 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 differ-
ences. Also, systems equipped with electronic or mechanical
air cleaners and/or humidifiers offer the added benefits of hav-
ing the air continuously cleaned year-round and humidified
during the winter season.
• A system equipped with a heat or energy recovery ventilator
offers the advantage of exhausting stale air from the home and
allowing fresh air in from the outdoors while minimizing heat
loss.
• Your system may also be equipped with a zoning system
which allows individual control over the temperatures of sep-
arate areas of your home.
• 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
