comfort!
Your new air conditioning unit represents
the culmination of many years of
experience from one of the most reputa-
ble manufacturers of comfort systems.
Your new unit is among the most reliable
and energy-efficient air conditioning
products available today. To assure its
dependability, spend just a few minutes

operation of your air conditioner, and the
small amount of maintenance it takes to
keep it operating at its peak efficiency.
With minimal care, your new air condi-

YOUR COMFORT
SYSTEM
Identifying Your System
Take the time to get to know the type of
system you have. This will be helpful in
understanding the basic operation of your
new air conditioner.
The split-system type has an indoor and
an outdoor unit, each of which contains a
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.
WARNING
To prevent personal injury,
death, or property damage,
read and follow all instructions
and warnings, including labels

conditioner.

coil. These units are interconnected by
refrigerant tubes. (See 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.
IMPORTANT FACTS
To better protect your investment and to
eliminate unnecessary service calls,
familiarize yourself with the following
facts:
Listen To Your Unit
Your air conditioner has a scroll
compressor. Get to know the character-
istic start-up and operational sounds.
Keep Filter Clean
Your air conditioning system should
never be operated without a clean air
filter properly installed. Plan to inspect
the filter periodically. 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, furni-
ture, and toys are some of the items
commonly found obstructing registers.
Restricted airflow lessens the unit’s
efficiency and life span.
Do Not Cover or Block
Outdoor Unit
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. mini-
mum 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 air condition-
ing 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 potentially 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.
Continuous Fan
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.
Air Cleaners and Humidifiers
Systems equipped with electronic or
mechanical air cleaners and/or humidifi-
ers offer the added benefits of having the
air continuously cleaned year-round, and
humidified during the winter season.
Ventilation
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.
Zoning
Your system may also be equipped
with a zoning system which allows
individual control over the temperatures
of separate areas of your home.
