COD. 79101EN.00 11/2013225. CONNECTIONS5.1 ELECTRICAL CONNECTIONThe system must be suitable for the electrical power of the boiler.The boiler is supplied with a power cable that needs to be connected toa 230V 50Hz outlet.The connection of the outlet to the back of the boiler is shown in thefigure.Ensure that the main switch of the boiler is at 0, and then connect the power cord first behind the boiler and theninto an electrical outlet on the wall. The main switch located on the back wall will be activated only when the boileris lit; otherwise, it is advisable to remove the cable from the boiler.Maximum electrical absorption while ignition (6 min) 490 WatElectrical absorption (Wat) 120 WatVoltage and supply frequency 230 V / 50HzBy law, the installation requires an earth connection and residual-current circuit breaker (RCCB). Make sure thepower cord, in its definitive position, does not make contact with hot parts.5.2 HYDRAULIC CONNECTIONFor the connection of the input water, output water, unloading and filling pipes, use longflexible tubes of at least 70 cm to facilitate the movement of the boiler for maintenance.INDICATIVE HYDRAULIC SCHEMEFrom the aqueduct towater reintegrationOutput water heating installalationInput water heating installationClosing flangeNon-returning valvePressure reducing valve
