• For suction heights exceeding 3 m we recommend securing the suction-hose (e.g. by fastening it to a
wooden post). This relieves the pump of the weight of the suction hose.

U
mechanical strain.
Priming the pump
Z
First, unscrew the filling plug to remove air from the pump during filling.
Fill the pump with clear water via discharge connector. Filling must be done slowly so that the air
contained in the pump is completely expelled. Fill to overflow and put back the filling plug. As this is
A
not an auto-priming pump, the suction pipe will also need to be filled. To save time when filling, you
can detach the suction pipe set and fill it directly (by submerging the suction pipe in water, for example)
before connecting the pump.

Depending on the suction height and the amount of air in the suction hose, priming can take anywhere
between 1 minute to 5 minutes. If it takes longer than this, the pump should be refilled with water.
