Performing Annual Maintenance
Electrical Shock Hazard
Disconnect power before doing any maintenance.
Do not drink water collected by the air
conditioner.
Failure to follow these instructions can result in
death, electrical shock, or sickness.
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.
Your air conditioner needs annual maintenance to help
ensure steady, top performance throughout the year.
Call your local authorized dealer to schedule an annual
checkup. The expense of an annual inspection is your
responsibility.

If you are familiar with electrical appliances, you can do
the cleaning and maintenance yourself. If you choose to
do so, follow these steps:
NOTE: Do not lift, push, or pull on any expanded gray
polystyrene from inside the air conditioner.
1. Unplug air conditioner or disconnect power.
2. Remove the air conditioner from the window.
3. Remove the front panel (See “Cleaning the front panel”
on page 14.)
4. Remove the side curtains. Slide curtains out to fullest
width. From the back side, remove the Phillips-head
screws which attach the curtain to the cabinet (A).
5. Remove slotted-hex head screws (B) holding top
channel.
6. Remove slotted-head screws (C) on sides of cabinet.
7. Holding the cabinet on both sides, carefully lift cabinet
off base. Watch out for the sharp metal fins on the front
and rear coils.
8. Wrap the fan motor(D), capacitor terminals (E),
electrical control box (F), and compressor terminals (G)
in plastic film and make sure no water or other liquid
gets inside any of these parts. It could damage the
insulation and cause serious mechanical problems.
9. Carefully clean and hose out the base (H), condenser
coil (I), evaporator coil (J), and condensate pan (K).
Clean at least once a year or more often if the
condenser and evaporator coils and pan collect dirt,
sand, leaves, insects, or algae. Also, clean if you detect
an odor coming from the air conditioner.
10. Remove the plastic film from the motor and electrical
parts.
11. Replace the cabinet on the air conditioner and reattach
the front panel, top channel and side curtains. Tighten
all screws.
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.
12. Plug in air conditioner or reconnect power.
