4 PLUMBING
4.11
Pipework:
For optimum performance pipework use 22 mm dia., 15 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 Although this pump is not self priming, once fitted with a footvalve and
strainer it can be used to draw water from a storage tank below the pump
position, or without a footvalve and stainer, from a tank above the pump
position.
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
Flooded suction conditions:
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.
4.17
Suction lift conditions:
Turn on isolating valves
(a) Loosen vent plug.
(b) Fill the pump head and suction
pipe with water from the discharge
port until filled with water.
(c) Re-seal vent plug.
