INSTALLATION WARNING! BEFORE PERFORMING ANY WORK ON THE BOILER, FIRST DISCONNECT IT FROM THE ELECTRICAL POWER SUPPLY USING THE EXTERNAL BIPOLAR SWITCH AND REMOVE THE FUSE. Electrical connections For increased safety, ask a qualified 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 2 The appliance must be connected to an effiecient 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. Important! In the event that the power supply cable must be changed, replace it with one with the same specifications. Power supply cable Electrical connection unit To access the electrical connection unit carry out the following steps: - Disconnect the boiler from the power supply - Loosen the screws on the cover of the outside connection boxes below the boiler (see diagram below) - Open the cover - The connection PCB may be accessed in order to connect : Connection box - Main supply - Live to pump - Zone valves - Outdoor sensor - Switched live connection/s - Cylinder stat a Connection box - Live to pump b 60 mm N L SWHV06 Important! The appliance is supplied with a fly-lead already connected, this must be connected to a 240V supply fused at 3 Amp and must facilitate completed electrical isolation of the appliance, by use of a fused double pole isolator having a contact separation of at least 3mm in all poles or alternatively by means of a 3A fused three pin plug and unswitched shuttered socket outlet both complying with BS1363. 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 effects caused by lightning. If the mains fuses need to be replaced, use 2A rapid fuses. T B BUS TA2 SE TNK SOL TA1 Caution!
