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.
Wiring Diagrams
The internal wiring within the terminal box are routed and secured to
ensure compliance with the electrical standard EN 60335-1. It is essential
that any disturbance of this internal wiring is avoided and the factory
routing and securing of all internal wiring is always maintained.
