6 Operation
To monitor the service life of the filter element/filter cartridge
during operation, the filter unit/filter housing is fitted with a
clogging indicator (back pressure/differential pressure, optical
or electric).
Visually check the optical clogging indicator daily. See chapter
Observing the optical clogging indicator (optional) [
The electric clogging indicator signals the required filter ele-
ment change through an electric switch which notifies the re-
mote control or another sensor.
When the clogging indicator has responded, change the filter
element/filter cartridge. Information on changing the filter ele-
ment can be found in chapter Performing maintenance.
6.1 Observing the optical clogging indicator (optional)
If the filter unit / filter housing is equipped with an optical clog-
ging indicator, then check it daily.

cal clogging indicator
Change the filter element at a permissible differential pressure
across the filter element or once the clogging indicator enters
the red zone.
