Indoor units are equipped with filters to remove the dust of sucked in air. Clean the filters using the methods shown in the following sketches.

Clean the filters using a vacuum cleaner or tap the filters against a solid object to knock off dirt and dust.

Are the filters especially dirty?

If the filters are especially dirty, wash them in lukewarm water. Take care to rinse off any detergent thoroughly and allow the filters to dry completely before putting them back into the unit.

Do not dry the filters 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, 122°F), as this may warp them.

Make sure that the air filters are always installed. Operating the unit without air filters can cause malfunction.

Using both hands, pull both the bottom corners of the intake grille to open the grille, then lift the filter until it clicks at the stop position.
