2. 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.
Do not run pump dry.
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
a)
Flooded suction installation
The pump must be primed (filled with water) before starting. Turn on water
supply, prime and vent the pump by unscrewing the priming plug (Figs. 9 & 10)
slowly until all air escapes and water emerges. Re-tighten plug.
