4. Open any shut-off devices in the delivery line (watering
accessories, water stop, etc.) so that air can escape before
the priming procedure begins.
5. Empty any water remaining in the delivery hose so that the air
can escape during filling and priming.

due to water being drawn off, the pump will switch on again
automatically.
The maximum self-priming head of 8 m is only achieved if the
pump is filled until it overflows via the filler connection
ቫ and the
delivery hose is held high enough so that no water can escape
via the delivery hose. It is not necessary to hold up the delivery
hose if filled suction hoses with backflow preventer are used.
