1. System Flushing
This pump-set incorporates 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.
2. Liquid Supply
Always ensure that liquid storage capacity is adequate to meet the demand.
Ensure the pump chamber is full of liquid before starting the pump. Failure
to do this could result in seal damage. To ensure dry running does not
occur the pumps 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 liquid) before starting. Turn on liquid
supply, prime and vent the pump by unscrewing the priming plug (Figs. 12 & 13)
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. 12 & 13).
