MAINTENANCE

WARNING
Before you clean the air conditioner, be sure to disconnect the power supply plug.
Cleaning the indoor unit and remote controller
• Use a dry cloth to wipe the indoor unit and remote controller.
• A cloth dampened with cold water may be used on the indoor unit if it is very dirty.
• Never use a damp cloth on the remote controller.
• Do not use a chemically-treated duster for wiping or leave such material on the unit for long, because it may
damage or fade the surface of the unit.
• Do not use benzine, thinner, polishing powder, or similar solvents for cleaning. These may cause the plastic
surface to crack or deform.
If you do not plan to use the unit for at least 1 month.
(1) Operate the fan for about half a day to dry the inside of the unit.
(2) Stop the air conditioner and disconnect power.
(3) Remove the batteries from the remote controller.
Checks before operation
• Check that the wiring is not broken off or disconnected.
• Check that the air filter is installed. (Some air-conditioners haven't air filters.)
• Check that the outdoor unit air outlet or inlet is not blocked.
Cleaning the air filter
• The air filter can prevent the dust or other particulate from going inside. In case of blockage of the filter, the
working efficiency of the air conditioner may greatly decrease. Therefore, the filter must be cleaned once two
weeks during long time usage.
• If the air conditioner is positioned in a dust place, the cleaning frequency of the air filter must be increased.
• If the accumulated dust is too heavy to be cleaned, please replace the filter with a new one (replaceable air filter
is an optional fitting).
1. Open the air-in grill.
Push the grill switches toward the middle simultaneously as indicated in sketch A. Then pull down the air-in grill.
Caution: The control box cables, which are originally connected with the main body electrical terminators
must be pulled off before doing as indicated above.
