4.1
Hydraulic installation
Choose a location complying with the conditions required by applicable law.
If the boiler is located on a lower level than any of the heating water pipes, it is recommended to fit
shut-off valves to the flow and return pipes, to avoid having to drain the installation when
maintenance work is carried out on the boiler.
Before connecting the boiler hydraulically, thoroughly clean the pipes.
Remember to provide for a fill valve connected to the flow or return heating circuit.
4.2
Electrical installation
Ensure the voltage in the home is the same as that indicated for the boiler. Make the electrical
connections in accordance with the electrical diagrams shown in this manual.
We recommend installing a main switch on the power lines enabling all supply phases to the boiler
to be cut off. A neutral phase is required to connect the boiler at 400 V 3N~ .
The boiler must be installed by a qualified technician, observing the applicable legislation. It must
be connected to a heating circuit or domestic hot water network in accordance with its features
and power.
