■ When resetting “FILTER” display
When the [FILTER] button is pressed 2 times successively after
cleaning the fi lter, the display goes off and is reset.
Note:
● When 2 or more different types of indoor unit are controlled, the cleaning
period differs with the type of fi lter. When the master unit cleaning period
arrives, “FILTER” is displayed. When the fi lter display goes off, the cumu-
lative time is reset.
● “FILTER” indicates the cleaning period when the air conditioner was used
under general indoor air conditions by criteria time. Since the degree of
dirtiness depends on the environmental conditions, clean the fi lter accord-
ingly.
● The fi lter cleaning period cumulative time differs with the model.
● This indication is not available for wireless remote controller.
► Cleaning the fi lters
• Clean the fi lters using a vacuum cleaner. If you do not have a vacuum clean-
er, 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), 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.
