Engineering notes
Conduct the electric connections in accordance with local regulations on electric
installations as well as the internal or connection diagrams.
Safety regulations and restrictions designed to ensure the safety of people and
property must be observed at all times!
A strainer should be fitted upstream of the valve. This increases reliability.
