6.1 Inspection
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 (See 6.2 Maintenance)
3. Slowly open shut-off valve on outlet
6.2 Maintenance
