UNIT
Select the tightening torque (about
4 Nm for the pipe connection range
¾" - 1¼" / about 10 Nm for the pipe

Draining of the backwash
water
CAUTION
An adequately sized waste water
connection (e.g. floor drain) in
compliance with DIN 1986 must be
provided.
In order to ensure safe drink-
ing water hygiene, a free dis-
charge of the waste water acc. to
DIN EN 1717 must be ensured.
The drain must be large enough so that all
of the waste water can be drained simulta-
neously.
If a waste water connection directly beneath
the filter is not possible, the backwash
water can be drained away via a hose or a
pipe that is connected from the backwash-
ing water valve over a few meters to the
closest waste water connection. The dimen-
sioning of this pipe must correspond to the
backwashing water valve.
If a bucket is used to drain off the back-
wash water:
•
Attention:
If the mains pressure is high,
water may spray out of the bucket. Pro-
tect objects near the bucket from water
damage!
•
Carry out the backwashing quickly and
finish the backwashing process as soon
as the bucket is half full. Otherwise the
bucket could overflow.
