Do not allow grass clippings, leaves, or other debris to

accumulate around or on top ofthe unit. Maintain a 10-in.

minimum clearance between the outdoor unit and tall

grass, vines, shrubs, et cetera.

• Your multi-purpose 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

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 heat pump 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.

Ofcourse, 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:

FIRE, EXPLOSION, ELECTRICAL SHOCK HAZARD

Improper installation, adjustment, alteration, service,
maintenance or use could cause fire, electrical shock

or other conditions which may cause personal injury,
death 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 heat pump 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.

THERMOSTAT

The operation of your heat pump 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 heat pump systems include
temperature control selector, FAN switch, and SYSTEM
switch. EMERGENCY HEAT control is usually provided

with the 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.

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 heat pump 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 another selection, AUTO. The
heat pump will not operate when the SYSTEM switch is set

at the OFF position. With the SYSTEM switch set at COOL,
your heat pump will operate in its cooling mode when the
indoor temperature rises above the level that you wish to

maintain. With the SYSTEM switch set at the HEAT
position, your heat pump will provide warmth 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
