Operating hours counters
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.
The grease filter operating hours
coun
ter 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
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.
– Select a longer time of 40 or 50
ho
urs if you use very little fat for
cooking.
Use the On/Off contr
ol to switch
the fan off.
