If two or more indoor units are connected, filter cleaning timing for each unit may be different, depending on the filter type.

The icon will appear when the filter on the main unit is due for cleaning.
When the filter sign is reset, the cumulative operation time of all units will be reset.

The icon is scheduled to appear after a certain duration of operation, based on the premise that the indoor units are installed in a space with ordinary air quality. Depending on the air quality, the filter may require more frequent cleaning.
The cumulative time at which filter needs cleaning depends on the model.

• This indication is not available for wireless remote controller.

Caution:

• Ask authorized people to clean the filter.

Cleaning the filters

• Clean the filters using a vacuum cleaner. If you do not have a vacuum cleaner, tap the filters against a solid object to knock off dirt and dust.
• 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.

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

2. Hold the knobs on the filter and pull the filter up, then pull it out downward.
   (Located in two places, on the left and right.)

   • A Front grille
   • B Filter

Caution

• 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), as this may warp them.
• Make sure that the air filters are always installed. Operating the unit without air filters 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 suckedin air. Clean the filters using the methods shown in the sketches above.

Cleaning the indoor unit

• Wipe the outside of the unit with a clean, dry, soft cloth.
• When dirt stands out, wash it with kitchen neutral detergent diluted with lukewarm water to the specified concentration, then wipe off the detergent with a damp towel.

Caution:
Never use gasoline, benzene, thinner, scouring powder or any type of non- neutral detergent, as these substances may damage the unit’s case.
