REGULAR MAINTENANCE
REQUIREMENTS
Your system should be regularly inspected by a qualified ser-
vice technician. Between visits, there are some routine
maintenance procedures you can do to help keep your sys-
tem operating at peak performance.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in
personal injury or death.
Turn OFF all electrical power to both the indoor and
outdoor units before performing any maintenance or
removing any panels or doors. There may be more
than one electrical disconnect switch
Air Filter
Inspect air filters at least monthly and replace or clean as re-
quired. Disposable type filters should be replaced. Reusable
type filters may be cleaned by soaking in mild detergent and
rinsing with cold water. Install filters with the arrows on the
side pointing in the direction of air flow.
Dirty air filters are the most common cause of inadequate
cooling performance, and of compressor failures.
Condensate Drain
The indoor coil condenses water from the air, and this water
must be disposed through an appropriate drain system. Dur-
ing the cooling season check at least monthly for free flow
of drainage and clean if necessary.
Outdoor Unit Coils
Grass clippings, leaves, dirt, dust, lint from clothes dryers,
and fall-off from trees can be drawn into coils by movement
of the air. Clogged outdoor coils will lower the efficiency of
your unit and could cause damage to the compressor. Clean
debris away from the outdoor coils.
Use a soft bristle brush with light pressure only. Do not dam-
age or bend coil fins. Damaged or bent fins may affect unit
operation.
Painted Surfaces
In geographical areas where the water has a high concentra-
tion of minerals (calcium, iron, sulfur, etc.) it is recom-
mended that lawn sprinklers not be allowed to spray on the
unit. Spraying this type of water on the unit may result in pre-
mature deterioration of the paint finish and metal compo-
nents.
Never use a weather cover over the outdoor unit unless it is
a ventilated type or made of breathable fabric that will allow
moisture to evaporate rapidly. A cover that holds moisture
in the unit will cause more rust build-up and damage than
normal exposure to weather.
REGULAR DEALER MAINTENANCE
In addition to the routine maintenance that you perform,
your home comfort system should be inspected regularly by
a properly trained service technician. The inspection (pre-
ferably twice each year, but at least once every year) should
include the following:
• Routine inspection of air filter(s). Replacement or
cleaning as required.
• Inspection and cleaning of the blower wheel, housing,
and motor as required.
• Inspection and, if required, cleaning of indoor and
outdoor coils.
• Inspection of the indoor coil drain pan, plus the
primary and secondary drain lines. If supplied, the
auxiliary drain pan and line should be inspected at this
time. Service should include cleaning if required.
• A check of all electrical wiring and connections.
• A check for secure physical connections of individual
components within units.
• Operational check of the air conditioner system to
determine actual working condition. Necessary repair
and/or adjustment should be performed at this time.
Your servicing dealer may offer an economical service con-
tract that covers seasonal inspections. Ask for further details.
FOR THE RECORD
Record the model, product, and serial numbers of your new
equipment. This information, along with the other ready ref-
erence facts requested, will be necessary should you ever re-
quire information or service.
