3. Ensure electrical supply is compatible with the details that are stated on the pump
rating plate. (The wrong voltage or frequency can be dangerous and may damage
the pump.)
4. Priming
(330, 500, 600, Kennet, Loddon and Thame Range)
a) Flooded suction installation
The pump must be primed (filled with liquid) before starting. Turn on liquid
supply, prime and vent the pump by unscrewing the priming plug (Figs. 21-25)
slowly until all air escapes and liquid emerges. Re-tighten plug.
b) Suction lift installation
A footvalve and strainer must be fitted to the end of the inlet pipework. Prime the
suction pipework by filling before connecting to the pump. Prime the pump by
filling via the priming plug (Figs. 21-25).
