► 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

completely 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 50°C), as this may

warp them.

• Make sure that the air filters are always installed. Operating the

unit without air filters can cause malfunction.

Caution:

• 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.
