6 Operation

Different operating modes are available depending on the ver-
sion (see the model code) of the filter unit.

The filter unit is equipped with a clogging indicator (differential
pressure gauge or dynamic pressure indicator) in the filter bowl
cover to monitor the service life of the filter element.

Visually check the optical clogging indicator daily. See chapter
"

Observing the optical clogging indicator (optional) [

The optional visual/electrical clogging indicator signals the re-
quired filter element change with an electrical switch which no-
tifies the remote control room or another sensor.

When the contamination display has responded, exchange the
filter element. Refer to chapter "" for detailed information on
changing the filter element.
