a) Use the anchor bolts to bolt the support stand to the concrete base.
b) Bolt the pump to the support stand and the suction connection.
2. Make sure that the pump is vertical for the T-installation or horizontal for the Z-
installation.
3. Connect the suction line and discharge line.
4. 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 23).
5. Make sure that the weight of the pump does not put strain on the piping.
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.
CAUTION:
If the pump is equipped with automatic level control and/or internal contactor, there is a
risk of sudden restart.
Requirements
These general requirements apply for electrical installation:
• The supply authority must be notified before installing the pump if it will be connected
to the public mains. When the pump is connected to the public power supply, it may
cause flickering of incandescent lamps when started.
• The mains voltage and frequency must agree with the specifications on the data plate.
If the pump can be connected to different voltages, then the connected voltage is
specified by a yellow sticker close to the cable entry.
