Local plumbing codes, general guidelines and the
technical data must be observed.
The system must be installed by the water supply
utility or a plumbing company approved by the water
supply utility in accordance with these installation
and operating instructions and the applicable re-
gulations.
The installation site must be frostproof and ensure
that the filter is protected from solvent vapours,
> 400 mm
heating oil, lees, acidic cleaners, chemicals of all
kinds, direct UV radiation and heat over 40 °C.
During pressure fluctuations and surges, the sum of
the pressure surge and the standing pressure must
not exceed the nominal pressure. The positive pres-
sure surge must not exceed 2 bar and the negative
pressure surge must not be less than 50 % of the
self-adjusting flow pressure (see DIN EN 806-2).
If the water contains dirt particles > 2 mm, a coarse
dirt trap must be installed upstream from the filter.
A flushing water quantity of at least 1.7l/s (6 m³/h)
and a pressure of min. 2,5 bar must be available
for backwashing
A drainage connection (min. DN 50/DN75) must be
available for discharge of the rinsing water.
Avoid extreme pressure surges (caused, for ex-
ample, by downstream solenoid valves or similar).

Install the backwash filter horizontally in the cold
> 20 mm
water line in the flow direction. (Observe the flow
direction arrow on the filter housing.)
Assemble pressure gauges (2).
Screw on the waste water connection, either for pipe
or for hose. Connect the drain line.
