5 Care and maintenance
5.3 Recirculation box with activated charcoal filters
An activated charcoal filter becomes less effective with use. With normal use,
the activated charcoal filters have to be changed every 3 years or whenever
the saturation indicator illuminates. The recirculation box contains 6 activ-
ated charcoal filters. These cannot be washed or regenerated. Replace all the
activated charcoal filters at the same time. The spent activated charcoal filter
can be disposed of in the household waste or at a suitable recycling point.
Activated charcoal filters are only used in the recirculation mode and
together with the recirculation box designed for this purpose.
Cleaning
Clean the housing, edges and
corners of the recirculation box –
having already taken out the 6
activated charcoal filters – with a
warm, damp cloth and a little de-
tergent, then wipe dry.
