COMMISSIONING

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.
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.
9.1 Priming
Never operate pump with inlet and/or outlet isolating valves in the
closed position. Damage will occur!
Do not remove manifold plug from top of pressure vessel manifold.
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. In the case of twin
pumps, both pump chambers must be independently primed.
Proceed to starting sequence.
9.2 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.
