COMMISSIONING / SYSTEM FLUSHING/ PRIMING / STARTING
7.11
7.12 Water Supply: Always ensure that water storage capacity is adequate to meet
the demand. Ensure the pump chamber is full of water before starting the
pump. Failure to do this could result in seal damage. To ensure dry running
does not occur the pump must be primed as described in priming section
below. Do not run pump dry.
7.13 Priming:
The pump must be primed (filled with water) before starting.
Turn on the service valves and vent/prime pump head.
(a) Loosen priming plug and allow an even flow of water this may take a
few seconds.
(b) Re-seal priming plug, nipping tight. The pump is now ready to start.
7.14 Starting:
a) Ensure all outlets are closed, turn power supply 'on' - pump will start,
pressurise the system then stop.
b) Open and close all outlets in turn associated with the pump, (including
w/c systems) allowing water to flow from each outlet until all air is purged.
As each outlet is opened and closed, the pump will start and stop
respectively.
Note: After closing the outlet there will be a small time delay before the
pump stops, which is normal.
c) Any tap or control valve within the system when opened and closed will
now turn the pump on/off. Providing this is the case the system is now
operating correctly.
d) Carefully check pump and pipework for leaks whilst pump running and
stationary before leaving the installation unattended.

the phone.
System Flushing
The pipework system should be flushed out prior to the pump
being connected to ensure any contaminants/chemical residues
and foreign bodies are removed from elsewhere in the system.
Never operate pump with inlet and/or outlet isolating valves in the
closed position. Damage will occur!
