Air Filter Cleaning
Vent Filter
TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.
The air filter should be checked at least twice a month to see if cleaning is necessary.
Trapped particles in the filter will build up and block the airflow. This reduces the cooling
capacity and also causes an accumulation of frost on the cooling coils.
If the filter becomes turn or damaged you should replace
immediately. Replacement filters are available from your
salesperson, dealer, and the authorized customer service
centers.
1. Remove the air filter from the front grille assembly by
pulling the air filter up slightly.
2. Wash the filter using lukewarm water below 104° F(40°C).
3. Gently shake the excess water from the filter completely.
Replace the filter.
Before cleaning the vent filter, disconnect power to the
unit by unplugging the power cord at the wall outlet or
subbase, or disconnect power at the fuse box or circuit
breaker. If unit is operated with vent door closed, the
vent filter does not need to be cleaned.
1. Remove the cabinet front as described in Front
Removal.
2. Remove the six screws securing the chassis to the
wall sleeve with a Phillips-Head screwdriver.
3. Slide the chassis out of the wall sleeve far enough so
that the vent filter is accessible as shown in Figure A.
4. Remove the vent filter by unscrewing the two screws
at the top of the filter and gently pulling the filter away
from the partition panel. Refer to Figure B.
5. Clean and replace the filter by reattaching the hook
to the bottom of the vent door and replacing the two
screws, slide the chassis back into the wall sleeve,
secure it in place with six screws and reinstall the
front cabinet.
