Care and Maintenance
The air filter behind the front grille should be checked and
cleaned at least once every 2 weeks or more often if
necessary.
• To Remove the Filter
1. Remove the front cover by gripping the top outside edges
and pulling toward you.
You will notice that the grille will only open to about a 56°
angle. Do not force the grille open too far.
2. Find the two clips that hold the filter in place.
Gently lift the filter out.
• To Clean the Filter
1. Clean with warm water. Be sure to shake all water off
before replacing the filter.
2. Carefully position the filter, bottom first, and snap the
grille back into place.
CAUTION: DO NOT operate the air conditioner without a filter
because dirt and lint will clog it and reduce
performance.
The coils on the outdoor side of the air conditioner should be
checked regularly. If they are clogged with dirt or soot they may be
professionally steam cleaned, a service available through a dealer.
Turn the air conditioner off and remove the plug
from the wall outlet before cleaning.
To clean, use water and a mild detergent. Do not
use bleach or abrasives.
In humid weather, excess water may cause the
BASE PAN to overflow. To drain the water,
remove the DRAIN CAP and secure the DRAIN
PIPE to the rear hole of the BASE PAN.
