NOISE
The equivalent continuous A-weighted sound pressure level from the pumpset does not
exceed 70 dB(A) at a distance of one metre.
COMMISSIONING
WARNINGS:

The motor casing can become very hot under normal operating
conditions, care should be taken to ensure it cannot be touched
during operation.
 Do not run pump without guards and terminal box lid correctly fitted.

The pump chamber must be full of liquid at all times. Seal damage
will result if the pump runs dry.
1. System Flushing
Some pumps incorporate plastic and rubber 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 the 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) End suction models (flooded suction)
These models are supplied with priming plugs fitted.
The pump must be primed (filled with liquid) before starting. Turn on liquid
supply, prime and vent the pump by unscrewing the priming plug (Fig. 17)
slowly until all air escapes and liquid emerges. Re-tighten the plug.
