If you have very extensive systems (with a large amount of water) or which require frequent refilling, the installation
of water softening systems.
It should be remembered that incrustations drastically reduce performance due to their
extremely low thermal conductivity.

9.1 GENERAL PRECAUTIONS
Electrical safety of the system is ensured only when it is properly connected to an efficient earthing system made
in compliance with the safety standards in force: gas, water or heating systems pipes are not suitable as earth
connections.
One must check this essential safety requirement; if in doubt, request an accurate inspection of the electrical
system to be carried out by qualified personnel, because the boiler manufacturer is not responsible for any
damage caused by failure to earth the system.
Have professionally qualified personnel check the electrical system is suitable for the maximum power absorbed
by the heating system, ensuring in particular that the diameter of cables is appropriate for the power absorbed
by the loads.
The use of any component that is powered by electricity entails compliance with some basic rules such as:
• do not touch the appliance with wet and/or damp body parts and/or bare feet;
• do not pull the electric cables;
• do not leave the appliance exposed to weathering (rain, sun, etc.);
• do not allow the appliance to be used by children or inexperienced persons.
230V electrical power supply connection
Installation of the boiler accessory electrical components requires electrical connection to a 230 V – 50 Hz mains:
This connection must be state of the art according to the CEI standards in force.
Hazard!
Electrical installation must be carried out by a qualified technician only.
Before performing connections or any operation on the electrical parts, always disconnect
the power supply and make sure it cannot be accidentally reconnected.
Please note that the boiler electrical power line must be fitted with a bipolar switch with
a contact gap greater than 3 mm, easy to access, in order to make any maintenance
operations quick and safe.
The power cable must be replaced by authorised technical personnel. Failure to comply with the provisions
listed above may compromise the safety of the appliance.
9.2 ELECTRICAL CONNECTION
First connect the power cable to the side of the boiler and then to a wall socket.
The main switch at the side must only be activated to switch the boiler on; otherwise, it is advisable to keep it
switched off.
It is recommended to disconnect the boiler power cable when the boiler is not used.
