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.
► 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.
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, 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.
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 filters using the methods shown in the following
sketches.

job, be careful not to fall.
• When the filter is removed, do not touch the metallic parts inside
the indoor unit, otherwise injury may result.
