Maintenance Instructions
Annual maintenance 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:
1. Unplug air conditioner or disconnect power.
2. Remove the air conditioner from the sleeve.
See pages 7-8.
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.
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.
9. Plug in air conditioner or reconnect power.
Energy saving tips
•Improve home insulation. Seal doors, windows,
and close fireplace flue.
•Close blinds or drapes on sunny side of house.
Add window awnings.
•Keep air filter clean. Do not block airflow with
drapes or furniture.

normal cooling load).
•Try not to use heat producing appliances during
the hottest part of the day. Turn lights, radios,
televisions, and other appliances off when not
needed.
•Keep heat registers and cool air returns closed
or blocked off so cooled air won’t escape.
•Use a vent fan in cooking, laundry, or bathing
areas to pull out heat and moisture near its source.

PROBLEM
Unit won’t run.
Unit blows fuses or
trips circuit breaker.
Unit turns on and
off, OR does not
cool room.
Normal operating sounds …
When your room air conditioner is operating
normally, you will hear sounds such as:
•Droplets of water hitting the condenser, causing
a “pinging”or “clicking”sound. Water droplets
help to cool the condenser.
•Air movement from the fan, especially on high
fan speed settings.
•Clicks from the cooling cycle.
Sounds also may be caused by house construc-
tion –such as vibration of the unit due to wall
construction or unsteady window mounting area.
