8.4.5.2 Rotary Direction

CAUTION – Never let the pump run dry,
not even for the purpose of checking the
direction of rotation! Dry running will
damage the pump and void the warranty.
Switch on the power supply and look at the rotary direction
by looking at the motor fan. An arrow on the pump unit
indicates the correct direction of the rotation.
Viewed from the top, the pump turns counterclockwise.

8.4.5.3 Final Check-up

Check whether the foundation bolts are fastened, the pump
and suction pipes are completely filled with water, the
voltage of the power supply is correct and that the pump
turns correctly. Make sure all pipelines are connected tightly
and can supply water normally. Make sure there is no closed
valve or other obstruction in the water line.
