• 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

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.

• 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 building, placement of

registers, et cetera. These air pockets may be too cool or

warm for your liking. Continuous fan operation minimizes
any temperature differences. Also, systems 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 air conditioner will remove humidity from your home
during 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 drainage if you live in

a very dry environment.

OPERATING YOUR UNIT

IMPORTANT FACTS

To better protect your investment and to eliminate

unnecessary service calls, familiarize yourself with the

following facts:

Improper installation, adjustment, alteration,
service, maintenance or use can cause fire,
electrical shock or other conditions which may
cause personal injury or property damage.

Refer to this manual. For assistance or additional
information consult a qualified installer, service

agency, distributor, or branch. The qualified
installer or agency must use only factory
authorized kits or accessories when modifying

this product.

• 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.

• 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.

• Outdoor units 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 10-in.

THERMOSTAT

The operation of your air conditioning system is controlled
by the indoor thermostat. You simply adjust the thermostat
and it maintains the indoor temperature at the level you
select. Most thermostats for air conditioning systems have
three controls. These are the temperature control selector,

FAN switch, and SYSTEM switch.

The temperature control selector is a dial or button(s) that
allows you to establish the degree of temperature that you

wish to maintain for your personal comfort. Some
thermostats possess two temperature control selectors:
one for setting the temperature desired during the cooling
cycle, and one to set the heating operation temperature (if
the accessory electric heater is used).

The FAN switch offers two options for controlling the
blower: AUTO and ON. When set to AUTO, the blower will

run during the time the air conditioner is operating. When
the FAN switch is set at the ON position, the blower will run
continuously.

Typically, the SYSTEM switch on your thermostat offers the
following selections: COOL, OFF, and HEAT. Your

thermostat may also have a fourth selection, AUTO. The
air conditioner will not operate when the SYSTEM switch is

set at the OFF position. With the SYSTEM switch set at
COOL, the cooling section of your comfort system will
operate when the indoor temperature rises above the level
that you wish to maintain. With the SYSTEM switch set at
the HEAT position, the accessory electric heater will
operate automatically whenever the indoor temperature
falls below the level that you have selected.

The AUTO selection found on some thermostats provides
for automatic changeover between cooling and heating
