6. Care and cleaning
6.1. 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.
Cleaning the indoor unit
• Wipe the outside of the unit with a clean, dry, soft cloth.
• Clean off any oil stains or finger marks using a neutral household de-
tergent (such as dishwashing liquid or laundry detergent).
Caution:
Never use gasoline, benzene, thinner, scouring powder or any type
of non-neutral detergent, as these substances may damage the unit’s
case.
