8.1 Inspection
8.1.1Pressure reducing valve
CAUTION!
Interval: once a year
1. Close shut-off valve on outlet
2. Check outlet pressure using a pressure meter when
there is zero through-flow
• If the pressure is increasing slowly, the valve may
be dirty or defective. In this instance, carry out
servicing and cleaning
3. Slowly open shutoff valve on outlet
8.2 Maintenance
CAUTION!
Frequency: every 1-3 years (depending on local
operating conditions). To be carried out by an
installation company
1. Close shut-off valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shut-off valve on outlet
4. Loosen hexagon nut on spring bonnet
