5.2.1 Backwashing interval
If cleaning is not performed soon enough,
the result may be damage to the sieve
insert. Large quantities of filtered particles
can deform the sieve fabric and in extreme
case lead to tearing of the sieve fabric.
In addition, larger deposit quantities can
impair the backwashing function mechani-
cally.
According to DIN EN 13443-1 backwashing
the device is required at the latest every six
months.
The manufacturer requires a backwash-
ing:
•
at least after a month
•
if the water pressure drops
•
if the filter is visibly dirty

Selection of the backwashing intervals
1) Dependent on the dirt formation
2) if necessary, securing of the filter acc. to DIN EN 1717
Experience has shown that new installa-
tions in the early stages of installation lead
to increased dirt deposits. In this case, a
more frequent backwashing is necessary.

interval

of one week.
