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 loca-
tions or conditions. The intake air filter is constructed of du-
rable 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 louver.
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.

Vent Screen
Before cleaning the vent screen, disconnect power to the unit

sleeve.

the vent screen is accessible.

to the partition panel.

into the wall sleeve, secure it in place with six screws and
