For safety purposes, have a competent person carefully check the
electrical system in the property, as the manufacturer will not be held
liable for damage caused by the failure to earth the appliance properly
or by anomalies in the supply of power. Make sure that the residential
electrical system is adequate for the maximum power absorbed by the
unit, which is indicated on the rating plate. In addition, check that the
Fig. 2.2
section of cabling is appropriate for the power absorbed by the boiler.
The boiler operates with alternating current, as indicated in the techni-
cal data table (7), where the maximum absorbed power is also indicat-
ed. Make sure that the connections for the neutral and live wires cor-
respond to the indications in the diagram. The appliance electrical
connections are situated on the reverse of the control panel (see the
servicing manual for further information)

other supply cord;
- The blue wire should be connected to the terminal marked "N";
- The brown wire should be connected to the terminal marked "L".

plied for connection to a 230 V ~ 50 Hz supply.
The supply must be fused at 3 A.
The method of connection to the electricity supply must facilitate com-
plete electrical isolation of the appliance, by the use of a fused double
pole isolator having a contact separation of at least 3 mm in all poles
or alternatively, by means of a 3 A fused three pin plug and
