Starting

1.Switch pump on.

2.Pull out push-button on dry-running sensor – pump starts. 

Hold push-button until pull on push-button lessens and it is held by the water pressure.

The water pressure required in the tee fitting is at least 0.8 bar. At a lower water pressure the dry-running sensor cuts out. If the pump is stopped it needs to be started again as described above. Thus an operation under automatic control (e.g. time switch) is not possible.
