The condensate pan may also need to be
cleaned periodically to insure indoor air
quality. The condensate drain can pick up
lint and dirt, especially with dirty filters.
Inspect the drain twice a year to avoid the
possibility of plugging and eventual overflow.
Compressor
Conduct annual amperage checks to insure
that amp draw is no more than 10% greater
than indicated on the serial plate data.
Fan Motors
All units have lubricated fan motors. Fan
motors should never be lubricated unless
obvious, dry operation is suspected.
Periodic maintenance oiling is not
recommended, as it will result in dirt
accumulating in the excess oil and cause
eventual motor failure. Conduct annual dry
operation check and amperage check to
insure amp draw is no more than 10%
greater than indicated on serial plate data.
Air Coil
The air coil must be cleaned to obtain
maximum performance. Check once a year
under normal operating conditions and, if
dirty, brush or vacuum clean. Care must be
taken not to damage the aluminum fins while
cleaning.
CAUTION: Fin edges are sharp.
Cabinet
Do not allow water to stay in contact with the
cabinet for long periods of time to prevent
corrosion of the cabinet sheet metal.
Generally, vertical cabinets are set up from
the floor a few inches to prevent water from
entering the cabinet. The cabinet can be
cleaned using a mild detergent.

Refrigerant System
To main tain sealed circuit integrity, do not
install service gauges unless unit operation
