Altering the operating hours
counter for the grease filter(s)
You can set the operating hours counter
to suit the type of cooking you do.
The factory default setting is a cleaning
interval of 30hours.
- Select a shorter time of 20hours if
you fry a lot.
- If you only cook occasionally, we
recommend that you still select a
short time. This is to prevent grease
hardening on the filter(s) and making
cleaning more difficult.
- Select a longer time of 40 or 50hours
if you use very little fat for cooking.

 Press the run-on  control and the
operating hours control  at the

duration, or  for a longer duration.
