Operation (Automatic and Manual modes)23
Operating hours counters
The number of hours the appliance has
been in operation is stored in memory.
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 changing the filters and
resetting the operating hours counter
can be found under "Cleaning and
care".
Altering the operating hours counter
for the grease filters
You can set the operating hours
counter for the grease filters to suit the
type of cooking you do.
The grease filter operating hours
counter is set at the factory for 30
hours.
– Select a shorter time of 20 hours if
you roast or fry a lot.
– If you only cook occasionally we
recommend that you still select a
short time because grease which has
built up gradually over a long period
of time will harden on the filters and
make cleaning more difficult.
– Select a longer time of 40 or 50
hours if you use very little fat for
cooking.
Use the On/Off control to switch
the fan off.
Press the run-on control 515 and
the operating hours control at
the same time.
The grease filter symbol and one of
the fan power level indicators flash.
Fan power level indicators 1 to IS show
the time set:
1............................................... 20 hours
2............................................... 30 hours
3............................................... 40 hours
IS............................................. 50 hours
Press the "" symbol for a shorter
operating time, or the "" symbol to
select a longer operating time.
Confirm the selection by pressing the
operating hours control .
All the indicators will go out
If you do not confirm within 4 minutes,
the cooker hood will revert to the old
setting.
