Operating hours counter
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 coun‐
ter for the grease filters to suit the type
of cooking you do.
It is set at the factory for 30 hours.
– Select a shorter time (20 hours) if you
fry a lot.
– If you only cook occasionally, we rec‐
ommend that you still select a rela‐
tively short time because grease
which has built up gradually over a
long period of time will harden on the
filters and make cleaning more diffi‐
cult.
– If you use very little fat for cooking,
select a longer time (40-50 hours).
Press the On/Off touch control to
switch the fan off.
Press the run-on control 515 and
the operating hours counter at
the same time.
The grease filter symbol and one of
the fan power setting indicators flash.

Fan power setting indicators 1 to IS

operating time, or the "" symbol to

in 4 minutes, the rangehood will auto‐
matically revert to the previous setting.
