► Cleaning the fi lters
• Clean the fi lters using a vacuum cleaner. If you do not have a vacuum
cleaner, tap the fi lters against a solid object to knock off dirt and dust.
• If the 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.
Caution:
• Do not dry the 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, 122 °F), as this
may warp them.
• Make sure that the air fi 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 fi lters to remove the dust of sucked-
in air. Clean the fi lters using the methods shown in the following
sketches.
When the is displayed on the
Main display in the Full mode, the
system is centrally controlled and
