er, tap the
fi
lters against a solid object to knock off dirt and dust.

fi
lters are especially dirty, wash them in lukewarm water. Take care to
rinse off any detergent thoroughly and allow the
fi
lters to dry completely
before putting them back into the unit.

fi
lters in direct sunlight or by using a heat source, such as an
electric heater: this may warp them.
• Do not wash the
fi
lters in hot water (above 50°C), as this may warp them.

lters are always installed. Operating the unit without
air
fi
lters can cause malfunction.
Caution:
• Before you start cleaning, stop operation and turn OFF the power supply.
• Indoor units are equipped with
