7.2. Assembly instructions
When connecting the solder sockets, do not solder
the sockets together with the domestic water
station. High temperatures destroy internal parts
which are important to the function!
First solder the sockets, then insert the available
backflow preventers; only then should you install the
domestic water station.
Observe the flow direction when mounting the back-
flow preventer.
1. Thoroughly flush pipework
2. Insert Venturi nozzle (only 2")
3. Install domestic water station
• Note flow direction
• Install without tension or bending stresses
4. Seal in pressure gauge
7.3. Discharge of reverse rinsing water
The reverse rinsing water must be routed to the drain channel
in such a way that no backwater can occur.
To do this there are 3 options:
1. Direct connection:
• Connector DN 50/70 as well as the necessary pipes
and siphon (3 elbows 90°) in DN 70.
2. Discharge into floor drain
3. Drain into open container.

8. Start-up

8.1. Setting outlet pressure

Set outlet pressure min. 1 bar under inlet pressure.
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Loosen slotted screw
• Do not remove slotted screw
5. Slacken tension in compression spring
• Turn adjustment handle counter clockwise (-) until it
does not move any more
6. Slowly open shutoff valve on inlet
7. Turn control handle until the setting scale shows the
desired value
8. Retighten slotted screw
9. Slowly open shutoff valve on outlet

8.2. Reverse rinsing

During reverse rinsing, an inlet pressure of at least 1.5 bar is
required. The reverse rinsing interval depends on the degree
of dirt in the water. At the latest every 2 months, reverse
rinsing should be carried out according to DIN 1988, Part 8.
To ensure convenient and regular adherence to the reverse
rinsing interval, we recommend installing an automated
reverse rinsing system Z11S.
Filtered water can also be tapped during reverse
rinsing.
8.2.1. Manual reverse rinsing
If reverse rinsing water is not to be discharged via a direct
connection, a collecting container must be positioned
beneath before reverse rinsing.
1. Open ball valve by turning the reverse rinsing button to
the stop point
• Select bar must be upright
• The patented reverse rinsing system starts
• When filtering with Double Spin Technology, a visual
function check is possible through the rotating red rotor
2. Close ball valve again after approx. 3 seconds. Repeat
procedure three times
• If the filter is extremely dirty, the procedure may have to
be repeated additional times
With aid of the memory ring, the next deadline for manual
reverse rinsing can be booked.
8.2.2. Automatic reverse rinsing with the Z11S
The automated reverse rinsing system Z11S 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.

9. Maintenance

We recommend a planned maintenance contract
with an installation company
In accordance with DIN 1988, part 8, the following measures
must be taken:
9.1. Inspection
9.1.1. Pressure reducing valve
Interval: once a year
1. Close shutoff valve on outlet
2. Check outlet pressure using a pressure meter when there
is zero through-flow
• If the pressure is increasing slowly, the valve may be
dirty or defective. In this instance, carry out servicing
and cleaning
3. Slowly open shutoff valve on outlet
