s s s s s Cleaning the filters
• Clean the filters using a vacuum cleaner. If you do not have a vacuum
cleaner, tap the filters against a solid object to knock off dirt and dust.
• If the filters are especially dirty, wash them in lukewarm water. Take care
to rinse off any detergent thoroughly and allow the filters to dry com-
pletely before putting them back into the unit.
Caution:
• Do not dry the filters in direct sunlight or by using a heat source,
such as an electric heater: this may warp them.
• Do not wash the filters in hot water (above 122°F), as this may warp
them.
• Make sure that the air filters are always installed. Operating the
unit without air filters can cause malfunction.
• Before you start cleaning, stop operation and turn OFF the power
supply.
• Indoor units are equipped with filters to remove the dust of sucked-in
air. Clean the filters using the methods shown in the following sketches.

the indoor unit, otherwise injury may result.
