Cleaning the filters
• Clean the filters using a vacuum cleaner. If you do not have a vacuum clean-
er, 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.
Filter removal
Caution:
• In removing the filter, precautions must be taken to protect your
eyes from dust. Also, if you have to climb up on a stool to do the
job, be careful not to fall.
• When the filter is removed, do not touch the metallic parts inside
the indoor unit, otherwise injury may result.
