Filter operating hours counter
The operating hours counter for the
grease filter is set at the factory for 30
hours. (This can be changed if re-
quired. See “Altering the grease filter
operating hours”).
After this set time has elapsed the indi-
cator lamp for the grease filter touch
control glows. The grease filters must
then be cleaned.
After the grease filters have been
cleaned and put back in place, the fil-
ter operating hours counter must be re-
set.
To do this, press the grease filter
touch control and hold for about 4
seconds.
The indicator lamp will go out.
