Altering the grease filter operating
hours counter
The operating hours counter for the
grease filter is set at the factory for 30
hours. This can be lengthened or
shortened to suit the type of cooking
you do. You can choose 20, 30, 40 or
50 hours.
– Select a short time if you roast or fry
a lot.
– If you use very little fat for cooking,
select a longer time.
– 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 filter and
make cleaning more difficult.
^ Switch the fan off with the joystick.
^ Press the run-on option control and
the grease filter control at the same
time.
The indicator lamp for the grease filter
touch control and one of the power
level indicator lamps will flash.
The power level indicator lamps show
the time which has been set:
1st lamp from the left = 20 hours
2nd lamp from the left = 30 hours
3rd lamp from the left = 40 hours
4th lamp from the left = 50 hours
^ Use the joystick to select the time
required.
Press to the left for a shorter
operating time, or to the right for a
longer time.
^ Confirm the selection by pressing the
grease filter control.
All the indicator lamps will go out.
If you do not confirm your selection
within 4 minutes, the rangehood will
automatically revert to the "old" data.
