To enter into the terminal compartment unscrew the 2 screws on the cover. (To access the screws, remove the decorative caps on the control access panel). It is mandatory, before installing the appliance, to perform an accurate control of the electrical system by verifying compliance with current safety standards, which is adequate for the maximum power absorbed by the water heater (refer to the data plate) and that the section of the cables for the electrical connection is suitable and complies with local regulations. The manufacturer is not liable for damage caused by lack of grounding or anomalous power supply. Before starting up the appliance, check that the power rating matches that given on the nameplate. The use of multi plugs, extensions or adaptors is strictly prohibited. It is strictly forbidden to use the piping from the plumbing, heating and gas systems for the appliance earthing connection. If the appliance is supplied with a power supply cable, should the latter need replacing, use a cable featuring the same characteristics . The power cord must be routed into the hole in the back of the appliance and connected to the thermostat terminals (M Fig.7-8). The appliance must be grounded with a cable (yellow/green and longer than the phase cable) connected to the terminals marked (G Fig.7-8). COMMISSIONING - Check that all the necessary components are supplied and for those not factory fi tted, that they are the type recommended by the manufacturer for the particular water heater. - Check that the water heater/components are undamaged. - Check that the discharge pipe is plumbed so that it falls continuously and that no taps, valves or other shut-off devices are installed in the pipe. - Check that the discharge pipe drains safely to waste and is readily visible. - Check, in the case where some components are not factory fi tted, that they are marked so as to refer to the warning label on the water heater. - Open all outlet taps. - Turn on the mains water supply. - Close taps in turn as water fl ow stabilises with no air bubbles. - Check for leaks. - Check that no water is passing through the safety valve(s). - Test the operation of the safety valve(s) by lifting/turning the lever/knob, and observing that water fl ows through and safely to waste. - Switch on electricity and set thermostat to at 60°C to reduce the build up of scale in hard water areas. - Check the water heats up. - Check that is secure and visible on the heater and related warning labels are fi tted to the controls. - Demonstrate operation to user, including operation of safety valve(s) and what to do if it/they operate(s). - Give this handbook to the user and discuss future maintenance. - Drain and refi ll the entire system ensuring it is fl ushed in accordance with BS6700. 13 / EN
