4.14 Suction lift installation: Self priming of suction hose.
First ensure both suction and delivery hose connections are airtight. Remove the
priming plug (Fig. 8) and slowly fill the pump body with water, whilst allowing the
air to escape. Replace the plug.
4.15 Suction hose: Ensure the suction hose end is fully submerged in the water
source and the delivery hose is open to enable the pump to vent air.
4.16 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 time delay before the pump
stops, which is normal.
4 COMMISSIONING
4.11 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.
4.12 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.
4.13 Priming: Prior to switching the pump on and connecting the outlet hoses to
the system pipework the pump chamber must be primed. The pump must be
primed (filled with water) before starting. Turn on water supply, prime and vent
the pump by unscrewing the priming plug (Fig. 8) slowly until all air escapes and
water emerges. Re-tighten the plug.
