5. Care and Cleaning
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.
