Adjusting the vacuum relief valve (not DC
11-Module S models)
The valve is pre-adjusted with a negative pressure of
(18 kPa). If this needs to be adjusted the fol-
lowing procedure should be used:
- Connect a manometer to the suction side
and measure with a fully closed inlet.
- Shut down the pump and demount the
vacuum relief valve.
- Remove the damper cover (1) and mea-
sure distance A.
- Loosen the locking nut (3)
-
Adjust the spring tension by turning the spring
plate (4).
The compression of the spring (2) determines the
opening pressure. Changing the distance A by 1.5
mm will give a corresponding change in pressure
of 1 kPa.
-
Remount the valve after adjustment and test
the pressure.
- Inspect all cables and connections, repair if
neccessary.
-
Remount the protective panels, power up the
pump and give it a test run.
