Maintenance interval
Check whether the wash water filter is clogged. See
section 7.2.
The interval is based on experience of the applica-
tion. (When the wash water pressure has dropped
to 0.5 bar below the normal value).
Check the filter panels for clogging and damage.
See section 7.4.
Once a week, or at another interval based on expe-
rience from actual application.
Inspect the inside of the filter: Make sure no lar-
ge objects that can get caught in the drum, filter
segments or sludge trough have entered the filter.
Also check that the reject does not accumulate (se-
diment) in the sludge trough.

the OFF position and lock with a padlock.
Once a week or another interval based on expe-
rience of the application.
