8.2 Preparations before commissioning

The below listed preparation actions are valid for applications
with flooded suction conditions.
1. Check that all screws are tight.
2. Check that all pipes and hoses are installed correctly.
3. Check all electrical connections.
4. Check that all fuses in the control cabinet are switched on.
5. Check the alignment of the coupling. See section
6.4 Alignment.
6. Check that the coupling guard is installed correctly and that all
screws are tightened to 10 Nm for M6 and 25 Nm for M8.
7. Check that all safety devices are installed.
8. Make sure that any storage tank and pump priming tank are
filled with water.
9. Set the pressure switches according to the instructions.
System pressure minus 0.5 bar can be used as a reference
value.
10. Open the isolating valves on the suction and discharge sides.
The static geometric suction pressure from the main water
tank will fill the suction pipe, discharge pipe and pump with
water.
11. Bleed all air from the pump casing and suction pipe by the
opening of the automatic relief valve at the top of the pump.
Rotate the shaft a few times if possible to evacuate any air
trapped inside the impeller passages.
12. Close the isolating valves on the suction and discharge sides.
