WARNING
Verify that the voltage and frequency of the electropump shown on the nameplate correspond to those available
on the mains.
DANGER - ELECTRIC SHOCK RISK
The installer must make sure that the electric system is grounded in accordance with the law in force.
DANGER - ELECTRIC SHOCK RISK
Make sure that the electric system has a high-sensitivity circuit breaker ∆=30 mA (DIN VDE 0100T739).
OVERLOAD PROTECTION
The single phase motors are protected from overloads by a thermal device installed in the winding.
The protection for the three phase motor must be installed by the user.
Supply cables and extensions should have a section below that of H07 RN-F.
The plug and connections should be protected by water splashes.

WARNING
Do not operate the pump dry, since lack of water could cause it to overheat. In this case, the water inside the system gets
very hot, so there is a risk of scalding. Take off the plug and let the system cool down.
WARNING
Do not run the electropump with a completely closed delivery.
