Installation
If no bypass valve is installed, a
shut-off valve must be installed
upstream of the unit in order to
interrupt the water supply during
installation, maintenance, repair or
malfunction of the device.
Filters with a nominal size of 65 or more
should preferably be installed in a horizon-
tal line. When operating in a vertical line,
the coarse particles deposited in the sludge
trap cannot be backwashed out as optimally
as when operating in a horizontal line.
3.3
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.
When draining the backwash
water with a"¾" pipe, make sure
that the ball valves are not twisted
and that there may be a leak. The
ball valves are secured with a seal-
ing adhesive.
The drain must be large enough so that all
of the wastewater can be drained simulta-
neously.
If a wastewater 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 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. 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.
