• RF thermostat : “Clean Filter”
Ask authorized people to clean the filter.
When resetting “FILTER” or “Clean Filter” display.
Resetting the indication, refer to the operation manual of each remote
controller.

When two 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 filter display goes off, the
cumulative time is reset. (Only for wired remote controller)
“FILTER” or “Clean 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 conditions,
clean the filter accordingly.
The filter cleaning period cumulative time differs with the model.

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.
