Operating hours counter
The cooker hood registers the length of
time it has been operated.
When the grease filter symbol  or the
charcoal filter symbol  lights up, the
operating hours counters are signalling
that the filters need to be cleaned or
changed. Further information about
cleaning and replacing the filters and
resetting the operating hours counter
can be found under “Cleaning and
care”.
Altering the operating hours counter
for the grease filter(s)
You can set the operating hours counter
to suit the type of cooking you do.
It is set at the factory for 30 hours.
– Select a shorter time of 20 hours if
you fry a lot.
– If you only cook occasionally, we
recommend that you still select a
short time. This is to prevent grease
hardening on the filter(s) and making
cleaning more difficult
– Select a longer time of 40 or 50 hours
if you use very little fat for cooking.
 Switch the cooker hood off. The
deflector plate must be retracted.
 Remove the grease filters.
The controls are accessible via the slots
for the grease filters.
 Press the run-on  control and the
operating hours control  at the
same time.
The Grease filter symbol  and one of
the fan power level indicators will flash.
Fan power level indicators 1 to B show
the time set:
1............................................... 20 hours
2............................................... 30 hours
3............................................... 40 hours
B .............................................. 50 hours
 Press the  control for a shorter
duration, or  for a longer duration.
 Confirm your choice with the
operating hours control .
All the indicator lights will go out.
If you don't confirm your selection
within 4minutes, the cooker hood will
automatically revert to the original
setting.
