The installer must ensure that the correct electrical connection has been made and that it is fully compliant with safety regulations. Before connecting the appliance to the power supply, make sure that: • The appliance is earthed and the plug is compliant with the law. • The socket can withstand the maximum power of the appliance, which is indicated on the data plate located on the appliance itself. • The voltage falls within the range of values indicated on the data plate. • The socket is compatible with the plug of the appliance. If the socket is incompatible with the plug, ask an authorised technician to replace it. Do not use extension cords or multiple sockets. ! Once the appliance has been installed, the power supply cable and the electrical socket must be easily accessible. ! The cable must not be bent or compressed. ! The cable must be checked...
