SPECIAL FEATURES
All components are DVGW certified
- Modular construction
- Ready for connecting a water-softening unit
- Ready for connecting a heating fill or refill unit
- Expandable with additional cold water connections
- Two water pressure strengths: The filtered water is available unreduced for the garden and garage water connection, or reduced for comfortable water usage in the house*
- User-friendly – users only need to open the view window to carry out reverse rinsing
- Elegant – domestic water installation is brought together in one insulated housing

METHOD OF OPERATION
The domestic water center combines in one appliance, backflow preventer, back
washable filter, pressure-reducing valve, drinking water distribution for
storage tank and domestic water installation, and tank safety group.
Check valve
The check valve is a mechanical securing system and only allows flow-
through in one direction. It opens automatically if the pressure on the supply
side is greater than the pressure on the filter combination. If there is
greater pressure on the filter combination than on the supply line, then the
check valve automatically closes because of the action force. In this way, no
water can flow back out of the building if the public water supply lacks line
pressure.
Filter combination
The filter combination combines reverse rinsing filter and pressure
reducing valve in one appliance.
The fine filter set consists of an upper part and a lower part. In
the”Filtering” operating status, the small top filter is closed so that the
water can only flush the main filter from outside to inside. When the ball
valve is opened for “backwashing”, the filter is pushed downwards until the
water supply to the outside of the main filter is interrupted.
The water flow through the top filter is simultaneously opened. During
backwashing, the top screen is flushed from the outside to the inside; the
rotating impeller and the main filter are flushed from the inside to the
outside. This guarantees effective filter cleaning with full pressure along
the entire screen area. When the ball valve is closed, the filter switches
automatically back to the operating position.
The integrated pressure-reducing valve functions according to the force
comparison principle. This means, in the pressure-free state, the spring
pushes downwards and the valve opens. If the pressure builds up in the
pressure-reducing valve of the downstream line, this acts on the membrane in a
way that closes against the spring force. Pressure fluctuations on the front
side do not influence the back pressure.
Safety valve
At heating water in the service water tank, the heated liquid expands and the
pressure rises in the system. If the maximum permitted system pressure is
exceeded, the spring and membrane inside the integrated safety valve are
pushed backward.
The liquid is drained until the pressure in the system has sunk back under the
maximum permitted pressure.
TRANSPORTATION AND STORAGE
Keep parts in their original packaging and unpack them shortly before use.
The following parameters apply during transportation and storage:

INSTALLATION GUIDELINES
Setup requirements
- Install in horizontal pipework with discharge and filter bowl downwards
- This position ensures optimum filter efficiency
- These domestic water centers are armatures that need to be maintained regularly
- Ensure good access
- The pressure gauge can be read off easily
- The degree of contamination can be easily seen with a clear filter bowl
- Simplifies maintenance and inspection
- The installation location should be protected against frost
- Related to the EN 806-2 it is recommended to install the device immediately after the water meter
- In order to avoid flooding, it is recommended to arrange a permanent, professionally dimensioned wastewater connection
