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 the service valves with the power turned off to the pump. Open the

nearest outlet to be pumped for 10-15 seconds then close.

Proceed to starting sequence.

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.
