2. Functional description

The filter insert is divided into two parts. In the „filtering" posi-
tion, only the lower, larger section is rinsed through by water
jets from outside to inside. The small upper section does not
come in contact with unfiltered water. When the ball valve is
opened for reverse rinsing, then the whole filter insert is
pushed downwards until the water supply to the outer side of
the main filter is stopped. Simultaneously, the water flow is
opened to the upper part of the filter. The water needed for
cleaning the filter passes through the upper filter section, then
the rotating impeller and the main filter from inside to outside,
i.e. the filter is reverse rinsed with filtered water. In that way
the upper filter is also cleaned by jets from the impeller. The
filter automatically switches back to the operating position
when the ball valve is closed again.
Filters with Double Spin Technology have turbine blades
which circulate the water and thereby set the rotor on the
upper filter into a rotational motion. The internal impeller
rinses off particles that have adhered to the upper filter at the
intersecting points with the rotor.
3. Application
Medium Water
The filter is constructed for drinking water installations. In
case of a process water application the filter has to be proven
individually.

7. Assembly
7.1 Installations Guidelines
• Install in horizontal pipework with filter bowl downwards
o This position ensures optimum filter efficiency
• Install shutoff valves
• Ensure good access
o Pressure gauge can be read off easily
o Degree of contamination can be easily seen with clear
filter bowl
o Simplifies maintenance and inspection
• The installation location should be protected against frost
• Fit immediately after water meter
o Corresponds to DIN 1988, Part 2
7.2 Assembly instructions
When connecting the solder sockets, do not solder
the sockets together with the filter. High tempera-
tures destroy internal parts which are important to
the function!
1. Thoroughly flush pipework
2. Install filter
o Note flow direction
o Install without tension or bending stresses
3. Seal in pressure gauge
