result in
severe personal injury or death. WARNING signifies hazards
that
could
result in personal injury or death. CAUTION is used
to identify unsafe practices which
would
result in minor person-

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 air conditioner.
The type of air conditioner 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 refrig-
erant tubes, as shown in Fig. 1.
Each unit has a rating plate affixed to it which 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. 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, familiarize yourself with the following facts:
• Your air conditioning 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 cover
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 air conditioning 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 temperature
selector on the thermostat for any reason for at least 5 minutes
after the compressor has shut off.
• 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
pockets may be too cool or warm for your liking. Continuous 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 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.
WARNING
To prevent personal injury, death, or property
damage, read and follow all instructions and
warnings, including labels shipped with or at-
tached to the unit before operating your new air
conditioner.
