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
(water system) pressure. To clean the
screen, the backwashing handwheel (
9
) is
turned in an anti-clockwise direction up to
the limit stop.
The filtered water flows from the inside out
through the screen surface in the suction
channel and takes the adhering particles
with it.
During this time filtered water
flows out.
The fine filter screen is cleaned.
At the same time the inside of the trans-
parent filter bowl 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.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
This backwashing process must be carried
out so that no more backwashing water
discharges.
If the closing process is interrupted the
flushing valve is not fully closed. Water
permanently escapes as a result. Apart from
high water consumption, this can also cause
water damage, especially if the back-
washing water is not discharged as
described in the chapter on “Discharging the
backwashing water”.
5.4.1 Backwashing interval
The domestic water station must be back-
washed:
–
every six months at the latest,
–
if the water pressure falls,
–
if the domestic water station is visibly
dirty.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
If the interval until the next backwashing is
longer than six months, the particles on the
filter screen can stick or a large filter pres-
sure resistance can result.
Unauthorised persons must not operate the
domestic water station! Persons who
operate the domestic water station must
observe the operating instructions. Failure
to observe these instructions can result in
damage to property and personal injuries.
Experience shows that increased dirt is
deposited during the initial running period. If
so, the unit has to be flushed more often
than usual.
All sizes of domestic water station
are backwashed with filtered water.
The supply of filtered water to the
household water pipe is maintained
throughout the backwashing pro-
cess. Dirty water cannot get into the
clean water side during backwash-
ing.
The degree of pollution as well as
the cleaning off operation can be
watched from outside.
There is a display button attached to
the domestic water station. It can be
slid along the months scale. This
enables the backwashing interval to
be monitored.
