COMMISSIONING - Check

COMMISSIONING - Check that all the necessary components are supplied and for those not factory fitted, 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 fitted, 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 flow 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 flows 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 fitted 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 refill the entire system ensuring it is flushed in accordance with BS6700. MAINTENANCE REGULATIONS (for qualified personnel) Before calling your Technical Servicing Centre, check that the fault is not due to lack of water or power failure. Caution: disconnect the appliance from the mains before conducting any maintenance work. Replacing parts (Fig. 4) Remove the enclosure to access the electrical equipment. To work on the electronic thermostat (Ref. T), disconnect the power supply cable (Ref. C) and the control panel wire (Ref. Y). Next, remove it from its slot, taking care not to bend the sensor support rod too much. To work on the control panel (Ref. W), disconnect the wire (Ref. Y) and loosen the screws. During reassembly, make sure that all components are put back in their original positions. In order to work on the heating element and the anode, the appliance must first be emptied. Undo the 5 bolts (C fig. 5) and remove the flange (F fig. 5). The heating element and anode are attached to the flange. During reassembly, make sure that the flange gasket, the thermostat and the heating element are put back in their original positions (Fig. 5). We recommend replacing the flange gasket (Z Fig. 6) every time it is disassembled. Use only original parts from authorised service centres authorised by the manufacturer. Periodical maintenance The heating element (R fig. 6) should be descaled every two years (the frequency must be increased, if water is very hard) to ensure it works properly. If you do not wish to use a liquid descaler (in this case please read the safety data sheets of descaling), you can simply break off the deposit, taking care not to damage the heating element's cladding. The magnesium anode (N fig. 6) must be replaced every two years, otherwise the decay of the warranty. In the presence of aggressive or waters rich in chloride it is recommended to check the status of the anode annually. To remove this, disassemble the heating element and unscrew from the support bracket. Check controls (where fitted) as per the following: - Line strainer - with the water supply turned off remove screen from strainer and clean of any detritus; - Expansion vessel - with the water supply turned off and taps open, check expansion vessel pressure and top up as necessary; - Temperature & pressure relief valve - with the water supply turned on, check manually by lifting the test lever/turning the test knob (ensure valve closes after testing); - Expansion relief valve - check manually by turning the test knob (ensure valve closes after testing); - Discharge pipes (D1) - from both temperature & pressure relief and expansion relief valve for obstructions; - Tundish & discharge pipe (D2)- open either valve gradually to produce a full bore discharge into tundish and D2 without any back pressure; - Pressure reducing valve - check that the correct outlet pressure is being maintained by recording the pressure at an in-line terminal fitting i.e. tap.

USER INSTRUCTIONS Reset/Diagnostics When one of the malfunctions described above occurs, the appliance will enter its “fault status” and all LEDs on the control panel will flash simultaneously. Reset: to reset the appliance, switch the product off and on again using the button (Ref. A). If the cause of the malfunction disappears immediately following the reset process, the appliance will resume normal operation. If this is not the case, all the LEDs will continue to flash; contact the Technical Assistance Centre. Diagnostics: to enable the diagnostic function, hold the button (Ref. A) for 5 seconds. The type of fault is indicated by five LEDs (Ref. 1 >5) according to the following scheme: LED Ref. 1 – Internal P.C.B. malfunction; LED Ref. 2 – Anode malfunction (in models fitted with active anode); LED Ref. 3 – NTC 1/NTC 2 temperature sensors broken (open or short-circuited); LED Ref. 5 – Water overheating detected by an individual sensor; LEDs Ref. 4 and 5 – General overheating (P.C.B. malfunction); LEDs Ref. 3, 4 and 5 – Operation without water. Exit the diagnostic function by pressing the button (Ref. A) or wait for 25 seconds. "Thermal disinfection cycle" function (anti-legionella) The anti-legionella function is activated by default. It consists of a heating/maintenance cycle of the water at 60°C for 1h so as to carry out thermal disinfection action against the relevant bacteria. The cycle starts at the first ignition of the product and after each re-ignition which follows a lack of mains power. If the product always work at a temperature below 55°C, the cycle is repeated after 30 days. When the product is off, the antilegionella function is not active. If the appliance is switched off during the anti-legionella cycle, the product turns off and the function is not completed. At the end of each cycle, the operating temperature returns to the value set previously by the user. The activation of the "anti-legionella cycle" is displayed as a normal temperature setting at 60°C. (Led Ref. 4). To permanently disable the anti-legionella function simultaneously hold down the "ECO" and "+" buttons for 3 sec.; confirming deactivation the led 40° will C flash rapidly for 4 sec. To reactivate the anti-legionella function, repeat the operation described above; to confirm the reactivation of the led (Ref. 4) will flash rapidly for 4 sec. Adjusting the temperature and activating the functions (Fig. 3) Press the button (Ref. A) to switch on the appliance. Set the desired temperature by using the “+” and “-” buttons to select a level between 40°C and 65°C. During the heating phase, the LEDs (Ref. 1> 5) corresponding to the temperature reached by the water so far remain lit in a fixed manner; all subsequent LEDs (up to the set temperature) flash progressively. If the temperature drops, for example after hot water has been used, the heating is reactivated automatically and the LEDs between the last fixed light and the light corresponding to the set temperature will resume flashing progressively. The first time the product is switched on, it will be set to a temperature of 60°C (Led Ref. 4). In the event of a power failure or if the product is switched off using the button (Ref. A), the most recently set temperature remains memorised. During the heating phase, a slight noise may be produced as a result of the water heating process. The LED remains ON during heating. ECO FUNCTION The Eco function is activated/deactivated by pressing the corresponding button. If the function is activated the led will be switched on. The Eco function aims to produce hot water by learning the user habits. So, for the first week ever the product memorises the tappings and the periods in which those tappings take place. From the following weeks the water heating is performed regarding what was learned previously. If the user wants to reset the function and start a new learning period, it is necessary to press the ECO button for 3 seconds (the eco led will appear blinking). If during Eco function, PLUS or MINUS button are pressed the function will be deactivated. SHOWER READY The Shower Ready LED (B, Fig. 3) indicates whether there is hot water for at least one shower. The quantity of hot water is determined by internal parameters and varies according to the model. MAX FUNCTION The Max function (C, Fig. 3) is activated/deactivated by pressing the corresponding button. If the function is active, the LED will be lit. The Max function temporarily sets the set-point temperature to 65°C by bypassing the previous operating mode (if the Eco function is active, the self-learning function is temporarily interrupted and deactivates on its own once the set-point is reached).
