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. Refer to Performing maintenance
chapter for detailed information on changing the filter element.
