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 to prevent grease
which has accumulated over a long
period of time from hardening on the
filters making cleaning more difficult.

fan.
Press the Delayed Shut Down and
grease filter buttons at the same time.

desired time.
