sense.
Wiring. Check electrical connections for tightness and/or
corrosion. Check wires for damage.
Filters. Check that filters are clean and in the proper
placement in the unit or duct system.
Louvers. Inspect air inlet louvers inside the heat exchanger
compartments. Ensure the area is clean and free of dirt and
debris.
Replacing or Cleaning the Filter
IMPORTANT NOTE: Never operate unit without a filter installed
as dust and lint will build up on internal parts resulting in loss of
efficiency, equipment damage and possible fire.
A return air filter is not supplied with this unit; however, there
must be a means of filtering the return air. The filter(s) may be
located in the return air duct(s). Consult with your installing dealer
for the actual location of the return air filter(s) in your unit.
A dirty filter is the most common cause of inadequate heating or cooling
performance. Filter inspection should be made at least every 2 months;
more often if necessary because of local conditions and usage.
Dirty throwaway filters should be discarded and replaced with a new,
clean filter. Dirty permanent filters should be washed with water,
thoroughly dried and sprayed with a filter adhesive before being
reinstalled. Filter adhesives may be found at many hardware stores.
Permanent filters should last several years. However, should one
become worn or uncleanable, it should be replaced.
When installing a new filter or reinstalling an old one, always make
certain the airflow arrows on the filter point in the proper direction.
Clean Outside Coil—Qualified Servicer Only
WARNING
To avoid personal injury or death due to electrical shock,

The coil, with the outside air flowing over it, should be inspected
annually and cleaned as frequently as necessary to keep the
finned areas free of leaves, grass, seeds and debris.
