5.1 Installations Guidelines
It is necessary during installation to follow the installa-
tion instructions, to comply with local requirements and
to follow the codes of good practice.
• Install in horizontal pipework with spring bonnet
directed upwards
• Install shutoff valves
• The installation location should be protected against
frost and be easily accessible
o Pressure gauge can be read off easily
o Simplified maintenance and cleaning
• For residential applications where maximum protec-
tion against dirt is required, install a fine filter upst-
ream of the pressure reducing valve
• Provide a straight section of pipework of at least five
times the nominal valve size after the pressure redu-
cing valve (in accordance with DIN 1988, Part 5)
