THROUGH-THE-WALL AIRCONDITIONER Use & Care Guide

Maintenance Instructions
Annual maintenance
Your air conditioner needs annual maintenance
to help ensure steady, top performance through-
out the year.
Call the service company recommended by
your dealer to:
l Inspect and clean the coils and condensate
water passages.
l Check fan.
The compressor and fan motor are sealed and
need no oiling. The expense of an annual
inspection is the customer’s responsibility.
OR
If you are familiar with electrical appliances, you
can do the cleaning and maintenance yourself.
If you choose to do so, follow these steps:
Electrical Shock Hazard
Unplug power cord from outlet
before servicing.
Be sure no liquid gets into the motor,
electrical control box, or compressor
terminals.
Failure to follow these instructions
can result in death, electrical shock,
or serious injury.
Excessive Weight Hazard
Use two or more people to move and
install air conditioner.
Failure to do so can result in back or
other injury.
1. Unplug power cord.
2. Remove the air conditioner from the sleeve.
See pages 7-9.
3. Remove the front panel. See page 12.
4. Remove the screws from the top and sides of
the cabinet, and then remove the cabinet.
Watch out for the sharp metal fins on the front
and rear condenser coils.
5. Wrap the motor, electrical control box, and
compressor terminal box in plastic film to
make sure no water or other liquid gets inside.
Water or other liquids could damage the
insulation and cause serious mechanical
problems.
6. Clean and hose out the base, coils, and
condensate pan. Clean at least once a year,
or more often if the condenser coils and pan
collect dirt, sand, leaves, insects, or algae.
Also, clean if you detect an odor coming from
the air conditioner.
7. Remove the plastic film from the motor and
electrical parts.
8. Reattach the cabinet with the screws. Replace
the front panel, and reinstall the air conditioner
in the sleeve.
9. Reconnect power supply.
NOTE: It is a good idea to wait 24 hours before
starting the air conditioner again. This allows time
for all areas to dry out. The water from rainfall or
from normal operation does not harm these
components.
