On models without a fan Selection Switch, the fan will cycle with the outdoor unit.
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 qualified service technician. These regular visits may include (am ong other things) checks for:
!Motor operation
!Ductwork air leaks
!Coil & drainpan cleanliness (indoor & outdoor)
!Electrical component operation & wiring check
!Proper refrigerant level & refrigerant leaks
!Proper airflow
!Drainage of condensate
!Air filter(s) perform ance
!Blower wheel alignment, balance & cleaning
!Primary & secondary drain line cleanliness
!Proper defrost operation (heat pumps)
There is som e routine maintenance procedures you can do to help keep your system operating at peak perform ance between visits.
Air Filter
Inspect air filters at least monthly and replace or clean as required. Disposable filters should be replaced. W ashable 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 com m on cause of poor heating / cooling perform ance and com pressor failures.
Indoor Coil
If the system has been operated with a clean filter in place, it should require minim al cleaning. Use a vacuum cleaner and soft brush attachm ent to rem ove any accumulation of dust from the top and underside of the finned coil surface. However, perform this maintenance only when the coil is com pletely 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 rem oval. You should not attem pt 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 dryers, and fall off from trees can be drawn into coils by movem ent of the air. Clogged condenser coils will lower the efficiency of your unit and could cause dam age to the condenser.
Periodically, debris should be brushed from the condenser coils.

SHARP OBJECT HAZARD!
Condenser coils have sharp edges. W ear adequate body protection on body extrem ities (e.g. gloves).
FAILURE TO FOLLOW THIS W ARNING COULD RESULT IN BODILY INJURY.
Use a soft bristle brush with light pressure only. DO NOT damage or bend condenser coil fins. Dam aged or bent fins m ay affect unit operation.
Painted Surfaces
For maxim um protection of the unit's finish, a good grade of autom obile wax should be applied every year. In geographical areas where water has a high concentration of minerals (calcium , iron, sulfur, etc.). It is recomm ended 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 prem ature deterioration of the unit finish and m etal com ponents.
In sea coast areas, special maintenance is required due to the corrosive atm osphere provided by the high salt concentration in ocean m ists 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.
IF YOUR SYSTEM DOES NOT WORK,
BEFORE REQUESTING A SERVICE CALL:
1.Ensure thermostat is set below (cooling) or above (heating) room tem perature and that the system lever is in the "COOL", "HEAT" or "AUTO" position.
2.Inspect your return air filter: If it is dirty your air conditioner may not function properly.
3.Check indoor and outdoor disconnect switches. Confirm circuit breakers are ON or that fuses have not blown. Reset breakers/replace fuses as necessary.
4.Inspect the outdoor unit for clogged condenser coils, (grass cuttings, leaves, dirt, dust or lint). Ensure that branches, twigs or other debris are not obstructing the condenser fan.
IF YOUR SYSTEM STILL DOES NOT OPERATE,
CONTACT YOU SERVICING DEALER.
Be sure to describe the problem , and have the model and serial numbers of the equipm ent available.
If warranted replacements parts are required, the warranty must be processed through a qualified distribution location.
