• 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.
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. (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.
This indication is not available for IR 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.
