STEP 5 COMMISSIONING
WARNINGS:
The motor casing can become hot under normal operating conditions,
care should be taken to ensure it cannot be touched during operation.
Do not run pump without guards and terminal box lid correctly fitted.
The pump chamber must be full of water at all times. Seal damage will
result if the pump runs dry.
1) 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.
2) 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. Do not
run pump dry.
3) Priming
WARNING
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,
prime and vent the pump by opening the outlet valve to allow pump to fill and vent.
In the case of twin pumps, both pump chambers must be independently primed.
4) Starting The Pump
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, 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 delay time before the pump
stops, which is normal.
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.
c) Carefully check pump and pipework for leaks whilst pump running and stationary
before leaving the installation unattended.
