Operation
Before starting
Check the oil level in the oil casing.
Remove the fuses or open the circuit breaker
and check that the impeller can be rotated by
hand.
Check that the monitoring equipment (if any)
works.
The impeller shall rotate clockwise, as viewed
from above. When started, the pump will jerk in
the opposite direction to the direction in which
the impeller rotates. See the fi gure.

Always lift the pump by its
carrying handle or lifting eyes,

The pumps are equipped with SMART ROTASENSE™ (rotation control). Note the following at start:
Connect the pump to power. If the pump fails to start and the fuses are correct, shift two phases in
the CEE plug or turn the knob on phase shifter to start the pump.
NOTE! Do not reverse phase sequence while pump motor is running. Doing so may cause temporary
incorrect rotation, resulting in damage to motor electronics and rotating parts.
If the pump still doesn’t start, call a qualifi ed electrician and ask him to check the mains and the
junctions.
Cleaning
If the pump has been running in very dirty wa-
ter, let it run for a while in clean water, or fl ush
it through the discharge connection. If clay,
cement or other similar dirt is left in the pump it
may clog the impeller and seal, preventing the
pump from working.
During a longer period out of operation, the
pump must be test run every other month to
prevent the mechanical seals from sticking to-
gether.
WARNING!
Watch out for the starting jerk,
which can be powerful.
