!
Never operate the appliance without filters.
f Inspect the filters for the first time three months after com-
missioning the appliance.
When the total fan runtimes reach the "Filter change interval"
value, which can be set by the qualified contractor, the program-
ming unit displays the "Filter" symbol.
The qualified contractor can lengthen or shorten the interval for
inspecting filters depending on the level of contamination.
The "filter" symbol appears after a time set by the qualified con-
tractor.
If the "filter" symbol illuminates, check the filters. Change the
filters if the surface is covered completely in dirt or the filter is
discoloured throughout.
Change the filters at least every 12 months.
