6.3 Discharge of reverse rinsing water
CAUTION!
According to EN1717 the space between bottom
from discharge connection at the filter and the
sewage piping (e.g. drain connection with syphon)
has to be 56mm at least.
To do this there are 3 options:
1. Discharge into floor drain
2. Drain into open container.
3. Discharge into drain connector with syphon (min.
DN70)
Filter size
DN65 - 100
*at 4.0 bar inlet pressure and 22 s reverse rinsing duration -
operated by actuator or at 4 bar inlet pressure and 3x 3 s
rinsing duration - operated by hand.

Operation

CAUTION!
Filter may only be operated with installed discharge
connection.
7.1 Reverse rinsing
CAUTION!
Interval:
at least every 6 month (acc. to EN806-5)
every 2 months (manufacturer's recommendation)
resp. depending on the degree of dirt in the water.
Red pointer integrated into the view window of one of
the pressure gauges for setting the next reverse
rinsing
Date for next reverse rinsing can be set at the memory
indicator of the outlet pressure gauge.
To ensure convenient and regular adherence to the
reverse rinsing interval, we recommend installing an
automated reverse rinsing system Z11AS.
During reverse rinsing, an inlet pressure of at least
1.5bar is required.
Filtered water can also be tapped during reverse
rinsing.
To avoid extra abrasion, we recommend to perform the
backwash at operating inlet pressures below 12 bar.
To ensure the proper backwash function also at
continuously higher media temperatures we advise to
follow the recommended service intervals. All the
internal parts should be checked to recognize possible
unusual abrasion.

7.1.1Manual reverse rinsing
A collecting container must be positioned beneath
before reverse rinsing if there is not drainage system
available..
1. Slowly open the ball valve
• The patented reverse rinsing system starts
2. Close ball valve again after approx. 3-5 seconds.
Repeat procedure three times
• If the filter is extremely dirty, the procedure may
have to be repeated additional times
7.1.2Automatic reverse rinsing with the
Z11AS
The automated reverse rinsing system Z11AS is available as
an accessory. The automated system reliably takes over
reverse rinsing of the filter at intervals which can be set
between 4 minutes and 3 months.
7.1.3Differential pressure controlled
reverse rinsing with the DDS76 and
Z11AS
Also available as an accessory is the DDS76 differential
pressure switch. It provides fully automatic operation of the
reverse rinsing which is controlled by the differential pressure
across the filter. It actuates a reverse rinsing cycle when the
pressure differential between the inlet and outlet of the filter
reaches a predetermined value. If the pressure difference
exceeds the preset value, then the Z11AS reverse rinsing
actuator is operated via its volt-free input.

Maintenance

We recommend taking out a servicing contract with an
installation firm
In accordance with EN 806-5, the following measures must
be taken:
8.1 Inspection
8.1.1Filter
CAUTION!
Interval:
at least every 6 month (acc. to EN806-5)
every 2 months (manufacturer's recommendation)
resp. depending on the degree of dirt in the water.
An increased differential pressure between inlet and
outlet pressure gauge indicates a highly contaminated
filter.
