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 simulta-
neously.
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.
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. Other-
wise the bucket could overflow.
