Filter operating hours counter
An indicator lamp shows when the
grease filter needs to be cleaned. The
operating hours counter for the grease
filter is set at the factory for a certain
number of hours but these can be
changed if required.
The operating hours counter for the re-
circulation micro-filter is set at the fac-
tory for an unlimited number of hours
but these can be changed if required.
After this set time has elapsed, the indi-
cator lamp next to the grease filter /
micro-filter touch control glows. The
grease filter must then be cleaned or
the micro-filter replaced by a new one.
After the grease filter has been cleaned
and put back in place or the micro-filter
has been replaced by a new one, the fil-
ter operating hours counter must be re-
set.
– To do this press the grease filter /
micro-filter touch control and hold for
about 4 seconds.
The indicator lamp will go out.
