LEGIONELLA BACTERIA FUNCTION

Legionella are small rod shaped bacteria which are a natural constituent of all fresh waters. Legionaries’ disease is a pneumonia infection caused by inhaling of Legionella species. Long periods of water stagnation should be avoided; it means the water heater should be used or flushed at least weekly.
The European standard CEN/TR 16355 gives recommendations for good practice concerning the prevention of Legionella growth in drinking water installations but existing national regulations remain in force.
This electronic storage water heater is sold with a thermal disinfection cycle function enabled by default.
Every time the product is switched on and every 30 days, the thermal disinfection cycle run to heat the water heater up to 60°C.
Warning: when this software has been carrying out the thermal disinfection treatment, water temperature can cause burns. Feel water before bathing or showering.

INSTALLING NORMS (for the installer)

CAUTION Observe all general warnings and safety standards listed at the beginning of this text in full; all such instructions are obligatory.

The appliance must be installed and commissioned by a qualified technician in accordance with established regulations and local health and safety regulations.
The appliance heats water to a temperature below boiling point. It must be linked up to a mains water supply according to the appliance performance levels and capacity.
Before connecting the appliance, it is first necessary to:
– Check whether the characteristics (please refer to the data plate) meet the customer’s requirements.
– Make sure the installation conforms to the IP degree (of protection against the penetration of liquids) of the appliance according to the applicable norms in force.
– Read the instructions provided on the packaging label and on the appliance data plate.
Installing the appliance
This appliance was designed to be installed only inside buildings in compliance with the applicable norms in force.
Furthermore, installers are requested to keep to the following advice in the presence of:
– Damp: do not install the appliance in closed (unventilated) and damp rooms.
– Frost: do not install the appliance in areas where the temperature may drop critically and there may be a risk that ice may form.
– Sunlight: do not expose the appliance to direct sunrays, even in the presence of windows.
– Dust/vapours/gas: do not install the appliance in the presence of particularly dangerous substances such as acidic vapours, dust or those saturated with gas.
– Electrical discharges: do not install the appliance directly on electrical supplies that aren’t protected against sudden voltage jumps.
In the case of walls made of bricks or perforated blocks, partition walls featuring limited static, or masonry different in some way from those stated, you first need to carry out a preliminary static check of the supporting system.
The wall-mounting fastening hooks must be designed to support a weight that is three times higher than the weight of the water heater filled with water.
Fastening hooks with a diameter of at least 12 mm (Fig. 3) are recommended. We recommend installing the appliance (A Fig. 1) as close as possible to the delivery points
to minimise heat loss along the pipes. Local  regulations may provide for restrictions on installation in bathrooms; observe any regulatory minimum distances.
To facilitate maintenance, make sure there is a clearance of at least 50 cm inside the enclosure for access to the electrical equipment.
Multi position installation
The product can be installed both vertically and horizontally (Fig. 2). During horizontal installation, rotate the appliance clockwise so that the water pipes are located to the left (cold water pipe at the bottom).
Hydraulic connection
Connect the water heater’s inlet and outlet with pipes or fittings that are able to withstand temperature in excees of 90 °C at a pressure exceeding that of the working pressure. Therefore, we advise against the use of any materials which cannot resist such high temperatures.
Screw a “T” piece union to the water inlet pipe with the blue collar. On one side of the “T” piece union, screw a tap for draining the appliance that can only be opened with the use of a tool (B fig. 2). On the other side of the “T” piece union screw the safety valve supplied (A fig. 2).
CAUTION! For those nations that have taken on European norm EN 1487, the pressure safety device pro- vided with the product does not comply with that norms. According to the norm, the device must have a maximum pressure of 0.7 MPa (7 bar) and have at least: a cut-off valve, a non-return valve, a control mechanism for the non-return valve, a safety valve and a water pressure shut- off device. Some countries may require the use of alternative safety devices, as required by local law; the installer must
check the suitability of the safety device he tends to use. Do not install any shut-off device (valve, cock, etc.) between the safety unit and the heater itself.
The device relief must be connected to a relief pipe that has a diameter at least identical to the one of the equipment connection. Use a funnel that creates an air gap of at least 20 mm and allows visual checks so that no personal injury, property damage or damage to animals will occur in case of safety device enabling.
The manufacturer will not be held responsible for such damage. Connect the inlet of the pressure safety device to the cold water system using a flexible pipe, using a cut-off valve if necessary (D fig. 2). In addition, a water discharge tube on the outlet C fig. 2 is necessary if the emptying tap is opened. When tightening the pressure safety device, do not over tighten and do not tamper with it. It is normal for water to trickle from the tap during the heating phase; for this reason, it is necessary to connect the drain, which must always be left exposed to the atmosphere, with a drainage pipe that is installed sloping downwards in a place with no ice. If the network pressure is closed to the
calibrated valve pressure, it will be necessary to apply a pressure reducer far away from the appliance.
To avoid any possible damage to the mixer units (taps or shower) it is necessary to drain any impurities from the pipes. The appliance must not be supplied  with water of hardness less than 12°F, nor with especially hard water (greater than 25 °F); we recommend installing a water softener, properly calibrated and controlled – do not allow the
residual hard- ness to fall below 15°F. Before using the appliance, we recommend filling its tank with water and draining it completely so as to remove any residual.
Electrical connection
Before performing any operations, disconnect the appliance from the electricity mains using the external switch.
Before installing the appliance it is recommended to thoroughly check the electrical system to verify compliance with established regulations; the manufacturer is not liable for damage caused by lack of grounding or anomalous power supply. Check that the system is suitable for the maximum power absorbed by the water heater (please refer to the
data plate) and that the cross-section of the electrical connection cables is suitable and complies with current laws. The use of multiplugs, 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 (type H05VV-F 3×1.5 mm 2 , 8.5 mm in diameter. The power cord (H05 V VF 3×1.5 mm2 diameter 8.5 mm) must be positioned in the special seat in the back of the appliance until it reaches the terminal (M Fig. 7, 8) then lock the individual wires, tightening the appropriate screws. Secure the power cord with the included cable clamp.
To disconnect the unit from the electrical supply use a bipolar, switch conforming to CEI-EN standards (contact opening at least 3 mm, better if equipped with fuses).
The appliance must be earthed and the earth cable (which must be yellow-green and longer than that of the phases) is fixed to the terminal marked by the symbol **(G Fig. 7, 8). Before starting up the appliance, check that the power rating matches that given on the appliance nameplate. If the appliance is not supplied with a power supply cable, choose one of the following installation modes:
– connection to mains with a rigid pipe (if the appliance has no cable clamp); use a cable with a minimum 3×1.5 mm2 section;
– with a flexible cable (type H05VV-F 3×1.5mm 2 , 8.5 mm in diameter) if the appliance is supplied with a cable clamp.
Startup and commissioning**
Before powering up the appliance, fill the heater with mains water.
To do so, open the mains cock and the hot water tap until all the air has been vented from the boiler. Check for water leaks from the flanges, from the by- pass pipe, tighten down the bolts not too much, if necessary (C Fig. 5) and/or the rings (W Fig. 7, 8).
Power the appliance by actuating the switch.
If you carry out horizontal installation you need to configure the correct display of the display by pressing the
“mode” button and the “eco” button simultaneously for 5 seconds.

MAINTENANCE REGULATIONS (for competent person)

CAUTION Observe all general warnings and safety standards listed at the beginning of this text in full; all such instructions are obligatory.
All maintenance operations and service visits should be performed by a competent person (who have the skills required by the applicable norms in force).
Before calling your Technical Servicing Centre, check that the fault is not due to lack of water or power failure.
Emptying the appliance
The appliance must be emptied if it is to be left unused in premises subject to frost.
When necessary, empty the appliance as follows:
– disconnect the appliance from the electricity mains;
– turn off the domestic mains tap;
– turn on the hot water tap (wash basin or bathtub);
– open the drain valve B (fig. 2).
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 first removing the power board (Ref. Z). The display board is attached to the product through two fixing side flaps (A Fig. 4a) accessible from inside the lower cover.
Release the control panel fixing flaps using a flat 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 fixing flaps. Pay special attention not to damage the plastic flaps 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, first drain the appliance (refer to the related paragraph). Remove the bolts (C Fig. 5) and remove the flanges (F Fig. 5).
The flanges 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. 7, 8 and 5).
Make sure that the flange 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 flange gasket (Z Fig. 6) every time it is disassembled.
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 pre- fer 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.
Safety valve
Regularly check that the overpressure device is not jammed or damaged; if it is, remove any scale or replace it.
If the device has a lever or knob, operate it to:
– drain the appliance, if necessary
– check its operation from time to time.

Power-off Memory Function
When reconnected to power after power off, the display panel will show the last operation setting so that the user can continue the operation setting. If there is no other actions after the display, the system will set current operation as default and the setting will automatically disappear in a minute.
ECO EVO Function
The “ECO EVO” function is a software program that automatically “learns” user consumption levels, reducing 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. At the end of this “learning” week, the software adjusts water heating according to the user’s real needs which are automatically identified by  theappliance. 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 first week. The process achieves maximum efficiency 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 it disables 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 learn 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 without 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” flashes quickly to confirm data cancellation
“Shower Ready” Display
The product is equipped with an intelligent function to minimise water heating time. Regardless of the temperature set by the user, the icon “shower ready” will turn on as soon as there is enough hot water for at least one shower (40 litres of mixed hot water at 40 °C). Upon reaching sufficient hot water for a second shower a second “shower ready” icon will light up and so on (the maximum number of showers depends on the ability of the model purchased).
Reset/Diagnostics
When any of the operation problems occur, the appliance goes into “fault status” and the corresponding error code flashes on the display (for example, E01). The error codes are the following:
E01 – internal error of the board
E04 – impressed current anode malfunction (corrosion protection is not guaranteed)
E09 – excessive number of resets in fifteen minutes
E10 – broken temperature probes (open or short circuited) – boiler outlet
E11 – excessive water temperature detected by single sensor – boiler outlet
E12 – general excessive water temperature (circuit board fault) – boiler outlet
E14 – Failure to heat water with powered heating element – boiler outlet
E15 – overheating caused by lack of water – boiler outlet
E20 – broken temperature probes (open or short circuited) – boiler inlet
E21 – excessive water temperature detected by single sensor – boiler inlet
E22 – general excessive water temperature (circuit board fault) – boiler inlet
E24 – failure to heat water with powered heating element – boiler inlet
E25 – overheating caused by lack of water – boiler inlet
E61 – internal malfunction of the circuit board (NFC communication)
E62 – internal malfunction of the circuit board (NFC data damaged)
Error reset: reset the appliance by switching it off and on from the ON/OFF button (Ref. A). If the cause of the malfunction disappears immediately when reset, the appliance resumes its regular operation. On the contrary, if the error code continues to appear on the display: contact the Technical Service Centre.

Additional Functions

Time remaining
For models equipped with user interface type shown in figure 9. The time remaining to reach the temperature set by the user (Ref. E) is shown in the centre of the display
(Ref. F). The value is indicative and is an estimate of the “time remaining” parameter. The value is automatically updated during the heating phase.
Anti-freeze function
The anti-freeze function is the appliances automatic protection to avoid damages caused by very low temperatures below 5 °C, in the event in which the product is turned
off during winter. It is recommended that the product remains plugged in to the mains power, even if it is inactive for a long time. The function is enabled; activation is displayed on the display with “AF”. For all models, once the temperature rises to a safer level such as to avoid damage from ice and frost, the water heating is switched off again.
“Thermal disinfection function” (anti-Legionella)
The anti-Legionella function is activated by default. It consists of a water heating/60°C temperature maintenance cycle for 1 hour which has a thermal disinfection action on  the relative bacteria. The cycle starts when the product is started up and when it is restarted after a power outage. If the product always functions at temperatures lower than
55°C, the cycle is repeated after 30 days. When the product is switched off, the anti-Legionella function is deactivated. If the equipment is switched off during the antiLegionella cycle, the product switches off and the function is deactivated. At the end of the cycle, the use temperature returns to the temperature previously set by the
user. Activation of the anti-Legionella cycle is displayed with AB letters (E fig. 9). To activate/deactivate the function, hold the “mode” button for 3 s. When “U1” is displayed, press Set button.

USEFUL INFORMATION

If the water comes out cold, have the following checked:
– the presence of voltage on the power terminal block (M Fig. 7, 8);
– the circuit board;
– the heating parts of the heating element;
– inspect the bypass pipe (X Fig. 7, 8);
– the sensor holder rods (K Fig. 7, 8).
If the water comes out boiling hot (steam in the taps)
Disconnect the appliance from the electricity supply and have the following checked:
– the circuit board;
– the amount of scale on the boiler and components;
– the sensor holder rods (K Fig. 7, 8).
If the hot water delivery is insufficient:
Have the following checked:

Water trickling from the pressure safety device
During the heating phase, some water may trickle from the tap. This is normal. To prevent the water trickling, a suitable expansion vessel must be installed on the flow system. If the trickling continues even after the heating phase, have the following checked:
– device calibration;
– the pressure of the water mains.
