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 wastewater can be drained simultane-
ously.
If a wastewater connection directly beneath
the device 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 wastewater connection. The dimen-
sioning of this pipe must correspond to the
backwashing water valve.
Attention:
•
The hose must run without kinks. The
hose or pipe must be laid with a con-
tinuous downward slope to the waste-
water connection.
•
If a continuous slope to the wastewater
connection cannot be realized at the
installation site, a lifting unit must be
installed to convey the backwash water.
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.
Protect 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.
