CLEANING
Intake Air Filters
To properly maintain the operational performance of
your PTAC unit, it is extremely important that the inlet
air filters be cleaned once per month or more often if
operated in dusty or dirty locations or conditions. The
intake air filters are constructed of durable
polypropylene. The "air intake" air filters can be easily
inserted into the cabinet front, using the filter guides.
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
filler:
1. Grasp each filter by its molded handle, located on the
front edge of the front, below the discharge grill.
