MAINTENANCE REGULATIONS

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 The electrical parts may be accessed by removing the cover (Fig. 7, 8). Intervene on the power board (Ref. Z) by disconnecting the cables (Ref. C, Y and P) and remove the screws. Intervene on the control panel by fi rst removing the power board (Ref. Z). The display board is attached to the product through two fi xing side fl aps (A Fig. 4a) accessible from inside the lower cover. Release the control panel fi xing fl aps using a fl at screwdriver to pry upon the same (A Fig. 4b) and release them from the pins, simultaneously push it outwards to free it from the seat. Repeat for both fi xing fl aps. Pay special attention not to damage the plastic fl aps as breaking them will not allow for correct assembly of the panel in its seat, resulting in possible aesthetic defects. After removing the control panel, you can disconnect the connectors of the rod carrying sensors and power board. Intervene on the rod carrying sensors (Ref. K) by disconnecting the wires (Ref. F) from the control panel and remove it from its seat, taking care not to excessively bend them. During reassembly, make sure that all components are put back in their original positions. To work on the heating elements and anodes, fi rst drain the appliance (refer to the related paragraph). Re move the bolts (C Fig. 5) and remove the fl anges (F Fig. 5). The fl anges are coupled to the heating elements and anodes. During reassembly, make sure to restore the rod carrying sensors and the heating elements to the original positions (Fig. 5, 7, 8). Make sure that the fl ange plate with the coloured writing H.E.1 or H.E.2, is mounted in its position marked by the same writing. We recommend replacing the fl ange gasket (Z Fig. 6) every time it is disassembled. Only for models equipped with user interface shown in fi gure 8. Se si deve sostituire l’anodo a corrente im pressa (Rif. Q), unscrew the nut, disconnect the cable and unscrew the anode from the fl ange. When you are putting it back in, replace the gasket, tighten the anode to a maximum torque of 2.5 Nm, connect the cable and tighten the relative nut to a maximum torque of 0.6 Nm. CAUTION! The reversal of the heating elements involves malfunction of the appliance. Work on one heating element at a time and remove the second only after replacing the first. Use only original spare parts. Periodical maintenance The heating element (R fig. 6) should be descaled every two years to ensure it works properly (R Fig. 6) approximately every two years (the frequency must be increased, if water is very hard). If you prefer not to use special liquids for this operation, simply crumble away the lime deposit without damaging the heating element. The magnesium anodes (N Fig. 6) must be replaced every two years (this does not apply to appliances with stainless steel boilers); however, the anode should be checked every year if the water is corrosive or chloride rich. To replace them, remove the heating elements and unscrew them from the brackets. The bypass pipe (X Fig. 7, 8) is inspected in the event of fault due to its obstruction. To inspect it remove the two rings (W Fig. 7, 8). After routine or extraordinary maintenance, we recommend filling its tank with water and draining it completely so as to remove any residual impurities. Use only original spare parts supplied by the manufacturer’s authorised service centres. 14 / EN

USER INSTRUCTIONS Advice for user - Avoid positioning any objects and/or appliances that could be damaged by water leaks beneath the water heater. - Should you not use any water for an extended period of time, you should: • disconnect the appliance from the electrical supply by switching the external switch to ‘’OFF”; • turn off the plumbing circuit taps; - Hot water at above 50°C fl owing out of the taps at the point of use could cause serious scalds or even death from burns. Children, the disabled and the elderly are more exposed to the risk of burns. It is strictly forbidden for the user to perform any routine or extraordinary maintenance. To clean the external parts use a damp cloth soaked in soap and water. Adjusting the temperature and activating the functions (Fig. 9-10) The product is set to “Manual” by default, with a temperature set to 65 °C and the function “ECO EVO” is active. In case of a power failure or if the product is switched off using the button ON/OFF (Ref. A), the last temperature set remains saved. Slight noise may occur during the heating phase due to the water being heated. Switch the appliance on by pressing the ON/OFF button (Ref. A). Set the desired temperature by selecting a level between 40°C and 65°C using the “ + “ and “ - ·:buttons. During the heating phase, the LEDs (Ref. 1-5) related to the temperature reached by the water remain on; the subsequent ones, until the temperature is set, fl ash progressively. If the temperature drops, for example due to water being drawn, the heating is auto matically reactivated and the LEDs between the last one on (steady) and that related to the set temperature start to fl ash progressively again. ECO EVO FUNCTION The “ECO EVO” function is a software program that automatically “learns” user consumption levels, redu cing heat loss to a minimum and maximising energy savings. The “ECO EVO” software consists of an initial saving period of a week, when the product begins to operate at the temperature set. Al the end of this “le arning” week, the software adjusts water heating according to the user’s real needs which are automatically identifi ed by the appliance. The product guarantees a minimum reserve of hot water even during periods in which water is not withdrawn. The hot water demand learning process, continues even after the fi rst week. The process achieves maximum effi ciency after four weeks of learning. Activate the function by pressing the corresponding button, which will light up. In this mode, the manual selection of the temperature is possible, however changing iidisables the “ECO EVO” function. Reactivate it by pressing the “ECO” button. Whenever the “ECO EVO” function or the product is turned off and on again, the function will continue to le arn the levels of consumption. In order to guarantee proper operation of the program, it is recommended not to disconnect the appliance from the mains. An internal memory ensures data storage for up to four hours wi thout electricity, after which all acquired data is cancelled and the learning process will begin from the start. Each time the knob is rotated to set the temperature, the “ECO EVO” function is automatically disabled and the relative writing turns off. The product continues to operate with the program selected, the ECO function is not active. To voluntarily cancel the acquired data, hold down the “ECO” button for more than 5 seconds. When the reset process is completed, “ECO” fl ashes quickly to confi rm data cancellation 15 / EN
