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
(among 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) 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 system 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 dryers,
and fall off from trees can be drawn into coils by movement
of the air. Clogged condenser coils will lower the efficiency
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 fins. Damaged or bent fins
may affect unit operation.
Painted Surfaces
For maximum protection of the unit's finish, 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 finish 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.
1.
Ensure thermostat is set below (cooling) or above
(heating) room temperature 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 equipment available.
If warranted replacements parts are required, the
warranty must be processed through a qualified distribution
location.
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.
