Maintenance

Chassis
The chassis must be cleaned every
six months or more often as the
atmospheric conditions require. Use
pressure water and detergent to
clean the basepan, center partition
and coils. The use of harsh cleaning
materials may cause a deterioration
of the coil fins or endplates.
Compressor / Fan Motor
The compressor and fan motor are
hermetically sealed, permanently
lubricated and require no additional
oiling.
Cabinet Front
The cabinet front and discharge air
grille can be cleaned with a mild
soap or detergent. Under no
circumstances should hydrocarbon
based cleaners (e.g. acetone,
benzene, naphtha gasoline, etc.) be
used to clean the front or outdoor air
grilles. Use care when cleaning the
control area. Do not use an
excessively wet cleaning cloth.
Intake Air Filter
The intake air filter and vent door
filter are both constructed of durable
polypropylene. The air intake air
filter is snapped into the cabinet
front, and the intake air grille swings
out for easy access to the filter.
Before cleaning the intake filter, turn
the unit off by setting the mode
switch to the OFF position. Filter
should be cleaned as required.
The following procedure is used to
remove the intake filter:
1. Open the intake grille by grasping
