INSTALLATION

If the system is used for the domestic water 

supply, respect the local regulations of the au-

thorities responsible for the management of 

water resources.

Choosing the installation site verified that:

-

The voltage and frequency on the pump’s 

technical data plate correspond to the values 

of the power supply system.

-

The electrical connection is made in a dry 

place, far from any possible flooding. 

-

The electrical system is provvided with a dif-

ferential switch  with I Δn ≤ 30 mA and that 

the earth system is efficient.

ELECTRICAL CONNECTIONS

Attention: always respect the safety regula-

tions! Electrical installation must be carried 

out by an expert, authorised electrician, who 

takes on all responsibility.

The system must be correctly and safely 

earthed as required by the regulations in force.

The line voltage may change when the elec-

tropump is started. The line voltage may un-

dergo variations depending on other devices 

connected to it and on the quality of the line.

The differential switch protecting the system 

must be correctly sized and must be of the 

“Class A” type. It must guarantee disconnec-

tion in the event of a category III over-voltage.

The automatic differential switch must be 

marked with the following two symbols:
