Note:
When 2 or more different types of indoor unit are controlled, the
cleaning period differs with the type of filter. When the master
unit cleaning period arrives, “FILTER” is displayed. When the fi l-
ter display goes off, the cumulative 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 con-
ditions, clean the fi lter accordingly.
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
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.
• Before you start cleaning, stop operation and turn OFF the power
supply.
• Indoor units are equipped with filters to remove the dust of
sucked-in air. Clean the fi lters using the methods shown in the
following sketches.
Filter removal
Caution:
• In removing the fi lter, precautions must be taken to protect your
eyes from dust. Also, if you have to climb up on a stool to do the
job, be careful not to fall.
• When the fi lter is removed, do not touch the metallic parts inside
the indoor unit, otherwise injury may result.
