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has been replaced by a new one, the fil-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.
To check the percentage of the time set
already used:
– Use the On/Off touch control to
switch the fan on.
– Press the grease filter / micro-filter
touch control.
One or several of the indicator lamps
between the
/ touch controls will
flash.
The number of flashing lamps indicates
the percentage of operating time set al-
ready used up.
1 lamp
= 25%
2 lamps = 50%
3 lamps = 75%
4 lamps = 100%
The number of operating hours used re-
mains in memory, even when the ap-
pliance is switched off or there is a
power cut.
