Altering the filter operating hours
counter
The filter operating hours counter is set
at 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
grease filters and make cleaning
more difficult.
^ Press the On/Off control to switch the
fan off.
^ Press the run-on option control and
the grease filter control at the same
time.
The indicator lamp for the grease filter
control and one of the – / + indicator
lamps will flash.
