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.
10.1 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.
1. Open the service valves.
2. Loosen priming plug and allow an even flow of water - this may take a few
seconds.
3. Re-seal draining plug, nipping tight. The pump is now ready to start.

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.
