When resetting “FILTER” display

When the [FILTER] button is pressed two 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 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 filters 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 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.

Pull both the bottom corners of the intake grille to open the grille,

then lift the ﬁ lter.
