Reverse rinsing filter combination with rotatable connector flange

APPLICATION

The filter combinations comprise a reverse rinsing filter and pressure reducing valve in one appliance. They ensure a continuous supply of filtered water. The fine filter stops the ingress of foreign bodies, for example, rust particles, strands of hemp and grains of sand and thus reduces the probability of corrosion. The pressure-reducing valve prevents pressure damage and reduces water consumption.
All individual units correspond to the requirements of current DIN/DVGW specifications. Technical features of each unit also apply to the combination assembly.

METHOD OF OPERATION

The filter combination combines reverse rinsing filter and pressure reducing valve in one appliance.
The downstream reverse rinsing fine filter holds back any dirt particles in the water. These particles are then completely flushed out by reverse rinsing.
Filters with Double Spin Technology have turbine blades that 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.
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 the opening or closing of the valve. Inlet pressure fluctuation does not, therefore, affect the outlet pressure.

TRANSPORTATION AND STORAGE

Keep parts in their original packaging and unpack them shortly before use.
The following parameters apply during transportation and storage:

Parameter Value
Environment: clean, dry, and dust-free
Min. ambient temperature: 5 °C
Max. ambient temperature: 55 °C
Min. ambient relative humidity: 25 % *
Max. ambient relative humidity: 85 % *

*non condensing

INSTALLATION GUIDELINES

Setup requirements

  • Install in horizontal or vertical pipework with filter bowl downwards
    – This position ensures optimum filter efficiency

  • Install shut-off valves

  • These filters are armatures that need to be maintained regularly

  • Ensure good access
    – Pressure gauge can be read off easily
    – Degree of contamination can be easily seen with a clear filter bowl
    – Simplifies maintenance and inspection

  • The installation location should be protected against frost

  • Fit immediately after the water meter

  •  Related to the EN 806-2 it is recommended to install the filter immediately after the water meter

  • In order to avoid flooding, it is recommended to arrange a permanent, professionally dimensioned wastewater connection
