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 aclean 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 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.

SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment
can be hazardous due to system pressure and electrical
components. Only trained and qualified personnel should
install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance
functions of cleaning coils and filters. All other operations

should be performed by trained service personnel. When
working on air-conditioning equipment, observe
precautions in the literature, tags, and labels attached to
the unit, and other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations.

Have fire extinguisher available for all brazing operations.

FIRE AND ELECTRICAL SHOCK HAZARD

Improper installation, adjustment, alteration, service,
maintenance, or use can cause fire or an explosion

which could result in personal injury or unit damage.

Consult a qualified installer, service agency, or gas

supplier for information or assistance. The qualified

installer or agency must use only factory-authorized kits

or accessories when modifying this product.

FIRE, AND ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal
injury, death and/or property damage.

Before performing service or maintenance operations

on unit, turn off gas supply to unit. Then turn off unit main

power switch and install lockout tag.
