Domestic water centre

APPLICATION

PrimusCenter is a compact product solution that brings together the complete spectrum of domestic water installation technology: Backflow preventer, backwashable filter, pressure-reducing valve, drinking water distribution for storage tank and domestic water installation, and tank safety group.

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

• Connection to the drinking water heater consists of a shut-off valve, a testable backflow preventer, and a safety valve

• Reverse rinsing actuator can be easily and quickly retrofit with bayonet connection

• Both pressure gauges of the filter combination and the dripping water of the safety valve are easy to inspect because of the transparent view window

• Red indicator on the view window for setting the next reverse rinsing

• 3-point installation system so that unevenness and sloping walls can be offset

• Supply line connection can be changed from left to right connection if required

• Connection option for sampling valve available

• Front and back pressure gauges are end point resilient

*DWC7000-1AAOA: the filtered and non reduced connection port is closed by a plug; retrofitting with the complete connection set (SOV70-3/4AA) is possible

PrimusCenter DWC7000 - Domestic water centre

METHOD OF OPERATION

The domestic water centre combines in one appliance, backflow preventer, backwashable 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 prepressure along the entire screen area. When the ball valve is closed, the filter switches automatically back to 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 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, spring and membrane inside the integrated safety valve are pushed backwards.

Liquid is drained until the pressure in the system has sunk back under the maximum permitted pressure.

INSTALLATION GUIDELINES

Setup requirements

• Install in horizontal pipework with discharge and filter bowl downwards

– This position ensures optimum filter efficiency

• These domestic water centres are armatures which need to be maintained regularly

• Ensure good access

– Pressure gauge can be read off easily

– Degree of contamination can be easily seen with 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
