Assembly

6.1 Installation Guidelines
• Install in horizontal pipework with spring bonnet
directed upwards
• Installation in vertical pipework possible with increased
maintenance effort
• Install shut-off valves
• The installation location should be protected against
frost and be easily accessible
– Pressure gauge can be read off easily
– Simplified maintenance and cleaning
• Install downstream of the filter or strainer
– This position ensures optimum protection for the
pressure reducing valve against dirt
• Provide a straight section of pipework of at least five
times the nominal valve size after the pressure reducing
valve (in accordance with EN 806-2)
• Requires regular maintenance in accordance with
EN 806-5
6.2 Assembly instructions
1. Thoroughly flush pipework
2. Install pressure reducing valve
• Note flow direction
• Install without tension or bending stresses
3. Seal in pressure gauges

Start-up

CAUTION!
Set outlet pressure 1 bar minimum under inlet
pressure
Close shut-off valve on inlet
Release pressure on outlet side (e.g. through water tap)
Close shut-off valve on outlet
Loosen hexagon nut on spring bonnet
Slacken tension in compression spring
Slowly open shutoff valve on inlet
Rotate adjustment screw, until the pressure gauge
shows the desired value
Retighten hexagon nut
Slowly open shutoff valve on outlet
