Operating hours counter
The number of hours the appliance has
been in oper
ation is stored in memory.
When the grease filter symbol or the
char
coal 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 gr
ease 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
fr
y a lot.
– If you only cook occasionally, we
r
ecommend 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.
– If you use very little fat for cooking,
select a longer time (40-50 hours).
Switch off the r
angehood. The
deflector plate must be retracted.

ve the grease filters.
The controls are accessible via the slots
