5 COMMISSIONING
5.11
System Flushing: This pump incorporates push-in connectors
and plastic components that must not come into contact with
solder flux, acid-based descalents or aggressive cleaning agents.
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.
5.12
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.
5.13
Priming:
Never operate pump with inlet and/or outlet isolating valves in the
closed position. Damage will occur!
The pump must be primed (filled with water) before starting. Turn on water
supply from the system service valves, prime and vent the pump by opening the
pump inlet and outlet isolating valves to allow pump to fill and vent.
In the case of twin pumps, both pump chambers must be independently primed.
5.14
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.
