1. Run the cable so that it has no sharp bends, is not pinched, and cannot be sucked into the pump inlet.
2. Connect the discharge line.
3. Lower the pump into the sump.
4. Place the pump on the base and make sure it cannot fall over or sink.
Alternatively, the pump can be suspended with a lifting chain just above the sump bottom. Make sure
that the pump cannot rotate at startup or during operation.
5. Connect the motor cable and the starter and monitoring equipment according to the separate
instructions.
Make sure that the impeller rotation is correct. For more information, see

General precautions
Electrical Hazard:
• A certified electrician must supervise all electrical work. Comply with all local codes and regulations.
• Before starting work on the pump, make sure that the pump and the control panel are isolated from
the power supply and cannot be energized. This applies to the control circuit as well.
• Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep the end of the
motor cable above the liquid level.
• Make sure that all unused conductors are insulated.
• There is a risk of electrical shock or explosion if the electrical connections are not correctly carried
out or if there is fault or damage on the product.
CAUTION:
If the pump is equipped with automatic level control and/or internal contactor, there is a risk of sudden
restart.
