Check/Action
Maintenance interval
Check whether the wash water filter is
clogged. See section 6.5.
The interval is based on experience from
the application in question. (When the
wash water pressure drops 0.5 bar below
the normal value.)
Check the filter panels for clogging and dam-
age, see section 6.7.
Once a week, or at another interval
based on experience from the
application in question.
Inspect the inside of the filter: Make sure no
large 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 (sediment) in the sludge trough.
NB
Prior to servicing, read section 2.7.
Remove large objects and rinse the sludge
trough.
WARNING! Turn the main power switch to
the OFF position and lock with a padlock.
Once a week or another interval based
on experience from the application in
