Functional description
The unfiltered water flows through the built-
in rotary flange (
4
) into the Domestic Water
station. The water flows through the fine fil-
ter from the outside inwards. The filtered dirt
is retained by the mesh of the fine filter
screen. The retained dirt can be seen from
the outside through the transparent filter
cover (
6
). The filter water flows on into the
pressure reducer (
2
). The downstream pres-
sure set can be read off at the manometer
(
3
). The filtered water then leaves the Do-
mestic Water station through the built-in ro-
tary flange (
4
).

Backwashing
The Domestic Water station must be back-
washed (=cleaned) at the specified cycles in
order to remove the filtered dirt from the fine
filter screen.
The backwashing takes place at full tap (wa-
ter system) pressure. To clean the screen,
the backwashing handwheel (
9
) is turned in
an anti-clockwise direction up to the limit
stop. The treated water flows from the inside
out through the screen surface in the suction
channel and takes the adhering particles
with it.
During this time treated water
flows out.
The fine filter screen is cleaned.
At the same time the inside of the transpar-
ent filter cover is cleaned with the wiper lips
of the suction pipe.
After cleaning the backwashing handwheel
must be turned in a clockwise direction (
9
)
up to the limit stop.
This backwashing process can be repeated
if necessary.

All sizes of Domestic Water station
are backwashed with treated wa-
ter. The supply of treated water to
the Domestic Water station is
maintained throughout the back-
washing process. Dirty water can-
not get into the clean water side
during backwashing.
Both the degree of soiling and the
cleaning process can be observed
from the outside.
