Maintenance And Cleaning; Intake Air Filter/Vent Screen/Cabinet Front - Amana Ptac Maintenance Manual

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 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 the top intake lou-
ver.
2. Pull the intake grille open.
3. Slide filter upward and remove.
4. Clean filter with vacuum or with running water.
Reverse this procedure to reinstall the filter.
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.
