6.2 Start and stop levels
Start and stop levels can be adjusted by changing the
free cable length of the float switch.
Long free cable = large difference in level.
Short free cable = small difference in level.
•
To prevent air intake and vibrations, install the
stop level switch, so the pump is stopped before
the liquid level reaches the upper edge of the
clamp.
•
Install the start level switch, so the pump is
started at the required level. The pump must
always be started before the liquid level reaches
the bottom of the inlet pipe.

6.3 Direction of rotation
All single-phase pumps are factory-wired for the
correct direction of rotation. Before starting up three-
phase pumps, check the direction of rotation. An
arrow on the stator housing indicates the correct
direction of rotation.
The impeller rotates clockwise. When
started, the pump jerks counterclockwise.
