6.1.6 Checklist for commissioning/start-up
Table 7: Checklist
Actions Done
1 Read the operating manual.
2 Verify the power supply against the name plate data.
3 Check the earthing system (taking measurements).
4 Check the mechanical connection to the water mains.
Re-tighten the flange bolting and pipe unions.
5 Prime and vent the pressure booster system from the inlet side.
6 Check the inlet pressure.
7 Check whether all cables are still firmly connected to the terminals inside the control unit.
8 Compare the set values of the motor protection switches with the name plate data; if required, readjust.
9 Briefly start up one pump after the other in manual mode and compare the direction of rotation at the
fanwheel with the arrow indicating the direction of rotation.
10 Check the start and stop pressure; re-adjust if necessary.
11 Check that the dry running protection equipment is working properly.
12 Vent the pumps for a second time after they have been running for 5 to 10 minutes.
13 Check the pre-charge pressure of the (membrane-type) accumulator.
14 Record all system conditions that do not correspond to our specifications or to the purchase order in the
commissioning report (i.e. no dry running protection or inlet pr max. pressure of pressure
booster system higher than 16 bar).
15 Complete the commissioning report together with the operator/user and instruct the operator/user as to
the function of the unit.
