MONTHLY MAINTENANCE AND CLEANING
Intake Air Filter
To properly maintain the operational performance of your
PTAC unit, it is
extremely
important that the inlet air filter
be cleaned once per month or more often if operated in
dusty or dirty locations or conditions. The intake air filter
is constructed of durable polypropylene. The “air intake”
air filter can be easily inserted into the cabinet front using
the cabinet filter guides. The intake air grille pulls upward
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. Grasp each filter by its molded handle, located on the
front edge of the front, below the discharge grill.
2. Pull the filter straight up and remove.
3. Clean filter with vacuum or with running water.
Reverse this procedure to reinstall the filters.
NOTE:
Available accessory filter kits are FK10B (air intake
filter - 10 per pack) and CFK10B (charcoal filter - 10 per
pack). The charcoal filters will greatly improve the quality
of the air by absorbing odors from tobacco smoke, mold,
mildew, etc. Both filters are permanent and cleanable.
Contact your sales person for details.
