Before you clean the air conditioner, be sure to disconnect the power supply plug.
• Use a dry cloth to wipe the indoor unit and remote control.
• 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 control.
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.
CAUTION
• Check that the wiring is not broken off or disconnected.
• Check that the air filter is installed. (Some air-conditioners do not have air filters.)
• Check that the outdoor unit air outlet or inlet is not blocked.
• 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 every two weeks during long time usage.
• If the air conditioner is positioned in a dusty 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).
• The filter cleaning should be performed by a suitable service provider.
