Maintenance
Regular Maintenance Requirements
Your system should be regularly inspected by a qualied
service technician. These regular visits may include
(among other things) checks for:
• Motor operation
• Ductwork air leaks
• Coil & drain pan cleanliness (indoor & outdoor)
• Electrical component operation & wiring check
• Proper refrigerant level & refrigerant leaks
• Proper airow
• Drainage of condensate
• Air lter(s) performance
• Blower wheel alignment, balance & cleaning
• Primary & secondary drain line cleanliness
Air Filter
Inspect air lters at least monthly and replace or clean as
required. Disposable lters should be replaced. Washable
lters may be cleaned by soaking in mild detergent and
rinsing with cold water. Allow lter to dry before reinstalling.
Replace lters with the arrows pointing in the direction of
airow. Dirty lters are the most common cause of poor
heating / cooling performance and compressor failures.
Indoor Coil
If the system has been operated with a clean lter in place,
it should require minimal cleaning. If cleaning is needed,
call your dealer for service.
Condensate Drain
During cooling season check at least monthly for free ow
of drainage and clean if necessary.
Condenser Coils
Grass cuttings, leaves, dirt, dust, lint from clothes dryers,
and foliage from trees can be drawn into coils by movement
of the air. Clogged condenser coils will lower the eciency
of your unit and could cause damage to the condenser.
Periodically, debris should be brushed from the condenser
coils. Use a soft bristle brush with light pressure only. DO
NOT damage or bend condenser coil ns. Damaged or
bent ns may aect unit operation.
SHARP OBJECT HAZARD!
Condenser coils have sharp edges. Wear adequate
body protection on body extremities (e.g. gloves).
FAILURE TO FOLLOW THIS WARNING COULD
RESULT IN BODILY INJURY.
WARNING
Painted Surfaces
For maximum protection of the unit’s nish, a good grade
of automobile wax should be applied every year. In
geographical areas where water has a high concentration
of minerals (calcium, iron, sulfur, etc.), it is recommended
that lawn sprinklers not be allowed to spray the unit. In
such applications, the sprinklers should be directed away
from the unit. Failure to follow this precaution may result
in premature deterioration of the unit nish and metal
components.
In sea coast areas, special maintenance is required due
to the corrosive atmosphere provided by the high salt
concentration in ocean mists and the air. Periodic washing
of all exposed surfaces and coil will add additional life to
your unit. Please consult your installing dealer for proper
procedures in your geographic area.
