WARNING:
• If you need to work on the pump, make sure that it is isolated from the power supply and
cannot be energized.
• Make sure that the unit cannot roll or fall over and injure people or damage property.
• In some installations, the pump and the surrounding liquid may be hot. Bear in mind the
risk of burn injuries.
• Make sure nobody is close to the unit when it is started. The unit will jerk in the opposite
direction of the impeller rotation.
NOTICE:
Make sure that the rotation of the impeller is correct. For more information, see Check the
impeller rotation.
1. Check the oil level in the oil housing.
2. Remove the fuses or open the circuit breaker, and check that the impeller can be
rotated freely.
3. Check that the monitoring equipment (if any) works.
4. Check that the impeller rotation is correct.
5. Start the pump.
Clean the pump
The pump must be cleaned if it has been running in very dirty water. If clay, cement or
other similar dirt is left in the pump it may clog the impeller and seal, preventing the pump
from working.
Let the pump run for a while in clean water, or flush it through the discharge connection.
