Connection to 230V electricity supply
The installation of the electrical accessory components of the boiler requires electrical connection to a mains
at 230 V – 50 Hz: This connection must be made according to best practice in accordance with the
applicable CEI standards.
Danger!
The electrical connection must only be performed by an authorised
technician.
Before making the connections or performing any servicing of electrical
parts, always disconnect the electricity supply and make sure it cannot be
re-established inadvertently.
Remember that an easily-accessed bipolar switch with a minimum contact opening
of 3 mm must be installed on the electrical power supply line to the boiler, in order
to facilitate and speed up any maintenance operations.
The power supply cable must only be replaced by authorised technical staff. Failure to observe the above
recommendations may compromise the safety of the appliance.
