Installation conditions
Observe all applicable installation regulations and
technical specifications. In some countries a system
separation is necessary when installing this filter.
The installation site must be protected against frost
and must guarantee the protection of the filter from
water splashes, solvent vapours, fuel oil, soap sud,
chemicals of all types, UV irradiation (sunlight), and
heat sources over 40 °C.
The filter is not suitable for producing drinking water
from water of unknown origin.
A strainer of 200 μm must be installed upstream of
the filter.
The water to be filtered must be drinking water that
fulfils the following quality criteria:
Free chlorine
Temperature
Maximum static pressure
Minimum flow pressure
The unit's maximum operational pressure must
never be exceeded (see above). If the network
pressure is higher, a pressure reducer must be
installed upstream of the unit.
The unit requires a minimum operational pressure
in order to function.
During pressure fluctuations or surges, the sum of
the pressure surge and the standing pressure
must not exceed the nominal pressure. The
positive pressure surge must not be greater than 2
bar, and the negative pressure surge must not be
less than 50 % of the self-adjusting flow pressure.
When installing the unit, select a location where
the unit can easily be connected to the water
supply network. A connection to the sewage
system (at least DN 50), a floor drain and a
separate power supply (230 V/50 Hz) must be
located in the immediate vicinity.
Th flushing water hose must be routed at an incline
to the sewage system or connected to a pump.

Installation
●Connect the unit as shown in the adjacent
diagram.
●A bypass is integrated into multiblock module.
●Installation is possible in horizontal or vertical
pipelines.
●Follow the separate installation instruction of the
Multiblock; otherwise the warranty is void if the unit
becomes damaged.
●Flush out any dirt particles by opening the
handwheel on the multiblock module.
●Connect a corrugated hose to the multiblock
module outlet and the hard water inlet (8). Be sure to
observe the arrows indicating the direction of flow.
●Connect a corrugated hose to the multiblock
module inlet and form a watertight seal with the
filtered water outlet (7).
●Route the flushing water hose at an incline to the
sewage system connection (drain) and secure the
end with the supplied fixing material to prevent it
flapping about when under pressure.
●The flushing water hose must be connected to the
channel with a distance of at least 20 mm from the
highest waste water level (unimpeded drainage).
