NOISE
The equivalent continuous A-weighted sound pressure level at a distance of 1 metre
from the pumpset does not exceed 70 dB(A).
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 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. Priming
a)
All models
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. 15)
slowly until all air escapes and liquid emerges. Re-tighten the plug.
