Fasteners
WARNING:
• Only use fasteners of the proper size and material.
• Replace all corroded fasteners.
• Make sure that all fasteners are properly tightened and that there are no missing
fasteners.
Install with S-installation
In the S-installation, the pump is transportable and intended to operate either completely
or partially submerged in the pumped liquid. The pump is equipped with a connection for
hose or pipe.
These requirements and instructions only apply when the installation is made according to
the dimensional drawing.
1. Run the cable so that it has no sharp bends. Make sure that it 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
Check the
impeller rotation (page 20).
Make the electrical connections
General precautions
Electrical Hazard:
• A certified electrician must supervise all electrical work. Comply with all local codes and
regulations.
• Before starting work on the unit, make sure that the unit 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.
WARNING:
Do not install the starter equipment in an explosive zone unless it is explosion-proof rated.
