When resetting "FILTER" display
When the [FILTER] button is pressed two times successively after
cleaning the filter, the display goes off and is reset.
Note:
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.
"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.
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.
