We recommend the use of a footvalve and strainer when a suction lift is required,
to reduce priming time.
4.14
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.
4.15
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.
4.16 Turn on the isolating valves.
(a) Loosen vent plug and allow an even flow of water this may take a
few seconds.
(b) Re-seal vent plug, nipping tight.
The pump is now ready to start.

4.11
Pipework:
For optimum performance pipework use 28 mm dia., 22 mm can be
used but will result in reduced pump performance.
4.12
Isolating valves:
Separate isolating valves (non restrictive) must be fitted to
allow easy pump service.
4.13 This pump has a self priming ability once filled with water. It can therefore be
used to draw water from a storage tank either above or below the pump position.
(c) Should the pump not build up pressure after running for 2-3 minutes
switch off and repeat priming process.

Maintenance:
This product is maintenance free for its life, however it is a mechanical product
and will eventually show signs of wear. Spare parts are available, for more
