1. Safety Guidelines
1. Follow the installation instructions.
2. Use the appliance
• according to its intended use
• in good condition
• with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the appli-
cations detailed in these installation instructions. Any
other use will not be considered to comply with require-
ments and would invalidate the warranty.
4. Please take note that any assembly, commissioning,
servicing and adjustment work may only be carried out by
authorized persons.
5. Immediately rectify any malfunctions which may influence
safety.
2. Description of function
The filter combination combines reverse rinsing filter and
pressure reducing valve in one appliance.
The filter insert comprises an upper part and a lower combi-
nation section. When in the „filtering“ position, the small upper
filter is closed so that the water can only pass through the
main filter from outside to inside. When the ball valve is
opened for reverse rinsing, the filter 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. During reverse rinsing, the screen is
flushed by flow from the outside; the rotating impeller and the
main filler are flushed by flow from the inside. By this means,
the filter is fully cleaned over its whole surface area at the full
inlet pres-sure. The filter automatically switches over to the
operating position when the ball valve is closed again.
The integral pressure reducing valve functions on a balanced
force principle whereby the force exerted by a diaphragm is
balanced against the force of an adjustment spring. The inlet
pressure has no influence on opening or closing of the valve.
Inlet pressure fluctuation does not therefore affect the outlet
pressure.

- Pressure gauge can be read off easily
- Degree of contamination can be seen with clear filter
bowl
- Simplifies maintenance and inspection
• The installation location should be protected against frost
• Fit immediately after water meter
- Corresponds to EN 806-2
7.2. Assembly instructions
1. Thoroughly flush pipework
2. Fit filter combination
• Note flow direction
• Install without tension or bending stresses
3. Seal in pressure gauge
