3.1. Cleaning the filters and the indoor unit
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.
