WARNING
Before performing any work on the boiler, fi rst disconnect it from
the electrical power supply using the external bipolar switch.
Electrical connections
For increased safety, ask a quali fi ed technician to perform a thorough
check of the electrical system.
The manufacturer is not responsible for any damage caused by the
lack of a suitable earthing system or by the malfunctioning of the
electricity mains supply.
Make sure that the system is able to withstand the maximum power
absorbed by the boiler (this is indicated on the appliance data plate).
Check that the section of the wires is suitable and is not less 0,75
mm

The appliance must be connected to an e ffi ecient earthing system if
it is to operate correctly.
The power supply cable must be connected to a 230V-50Hz network,
where the L-N poles and the earth connection are all respected.
In the event that the power supply cable must be changed, replace it
with one with the same speci fi cations.

The use of multiplugs, extension leads or adaptors is strictly
prohibited.
It is strictly forbidden to use the piping from the hydraulic, heating
and gas systems for the appliance earthing connection.
The boiler is not protected against the e ff ects caused by lightning. If
the mains fuses need to be replaced, use 2A rapid fuses.
Important!
Connection to the electricity mains supply must be performed
using a fi xed connection (not with a mobile plug) and a bipolar
switch with a minimum contact opening of 3 mm must be fi tted.
