of soiling of the water passing through it.
• To do this, pick up the filter element using the bracket and
rinse it off from underneath.
• We strongly advise against using chemical or mechanical
cleaning agents.
• Check and clean the seal before inserting the filter element,
replace it if necessary.
• We recommend monthly inspection and cleaning.
6.2. Rainwater filter with back-flushing unit:
In the case of the KESSEL rainwater filter with back-flushing
unit, it is not necessary to remove the filter insert. Depending
on the degree of soiling, the shut-off valve is opened for 30
to 60 seconds and the filter thus automatically flushed out.
The back-flushing process can also be fully automated in the
case of rainwater management systems with Aqatronic K
control units. Back-flushing then takes place at set time in-
tervals for the set time.

All KESSEL rainwater filters for installation in the ground or
for installation in an exposed drain pipe are available either

flushing unit may only be used with service water.
The back-flushing unit can be installed later, either in a filter
shaft for installation in the ground or in a filter shaft for in-
stallation in exposed pipes, as appropriate.
