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:
Parameter | Value |
| Environment: | clean, dry and dust free |
| Min. ambient temperature: | 5 °C |
| Max. ambient temperature: | 40 °C |
| Min. ambient relative humidity: | 25 % * |
| Max. ambient relative humidity: | 85 % * |
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
