Reprogramming the grease filter
timer
The grease filter timer is preset to 30
hours. This time can be lengthened or
shortened to 20, 30, 40 or 50 hours.
– A time of 20 hours should be
programmed in kitchens with
frequent pan or deep frying.
– A time of 20 hours should also be
programmed if the kitchen is only
used occasionally. Otherwise grease
which has accumulated over a long
period of time will harden on the
filters making cleaning more difficult.
^ Press the On/Off button to turn off the
fan.
^ Press the Delayed Shut Down and
grease filter buttons at the same time.
The indicator for the grease filter and
one of the "–/+" indicators will flash.
The lit "–/+" indicator shows the
programmed time:
1st indicator from the left
2nd indicator from the left = 30 hours
3rd indicator from the left
4th indicator from the left
^ Use the "–/+" buttons to select the
desired time.
^ Store the selection by pressing the
grease filter button.
If the procedure is not stored within
4 minutes of programming, the hood
will automatically default to the "old"
data.
