Cleaning and care
Always replace the charcoal filter im-
mediately if
– the indicator lamp for the charcoal
filter lights up,
or
– if it is no longer effective in absorbing
kitchen odours.
It should, however, be replaced at least
every 6 months.
Used charcoal filters can be disposed
of with the normal household waste.
^ After fitting the new charcoal filter,
press the charcoal filter touch control
for approximately 3 seconds to reset
the operating hours counter.
The charcoal filter indicator lamp will
go out.
If the charcoal filter is replaced before
the operating hours counter has
reached its maximum, the charcoal
filter touch control should be pressed
for approximately 6 seconds to reset
the counter.
