9. Care and cleaning

9.1. Cleaning the ﬁ lters and the indoor unit

Caution:

• Ask authorized people to clean the ﬁ lter.

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 suckedin air. Clean the filters 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.
