 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), 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.
10. Care and Cleaning
 Caution:
•  In removing the filter, precautions must be taken to protect your 
eyes from dust. Also, if you have to climb up on a stool to do the 
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.
