Important System Information

• Your system should never be operated without a

clean air filter properly installed.

• Return air and supply air registers should be free

from restrictions or obstructions to allow full flow of

air.

Regular Maintenance Requirements

Your system should be regularly inspected by a

qualifed service technician. These regular visits may

include (among other things) checks for:

• Motor operation

• Ductwork air leaks

• Coil & drainpan cleanliness (indoor and outdoor)

• Electrical component operation & wiring check

• Proper refrigerant level & refrigerant leaks

• Proper airflow

• Drainage of condensate

• Air filters(s) performance

• Blower wheel alignment, balance & cleaning

• Primary & secondary drain line cleanliness

• Proper defrost operation (heat pumps)

There is some routine maintenance procedures you

can do to help keep your system operating at peak

performance between visits.

Air Filter

Inspect air filters at least monthly and replace or clean

as required. Disposable filters should be replaced.

Washable filters may be cleaned by soaking in mild

detergent and rinsing with cold water. Replace filters with

the arrows pointing in the direction of airflow. Dirty filters

are the most common cause of poor heating/cooling

performance and compressor failures.

Indoor Coil

If the sytem has been operated with a clean filter in

place, it should require minimal cleaning. Use a vacuum

cleaner and soft brush attachment to remove any

accumulation of dust from the top and underside of the

finned coil surface. However, perform this maintenance

only when the coil is completely dry.

If the coil cannot be cleaned by this method, call your

dealer for service. It may need a detergent solution and

rinsing with water for cleaning, which may require coil

removal, You should not attempt this yourself.

Condensate Drain

During cooling season check at least monthly for free

flow of drainage and clean if necessary.

Condenser Coils

Grass cuttings, leaves, dirt, dust, lint from clothes dry-

ers, and fall off trees can be drawn into coils by

movement of the air. Clogged condenser coils will lower

the efficiency of your unit and cause damage to the

condenser.

such applications, the sprinklers should be directed away

from the unit. Failure to follow this precaution may result

in premature deterioration of the unit finish and metal
