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 the 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)

This product is a device that must be installed vertically in order to operate correctly. Once installa-tion is complete, and before any water is added or the power supply is connected, use a measuring instrument (i.e. a spirit level) to check that the device has been installed perfectly vertical.
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.
  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:

• Humidity: 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 are recommended (Fig. 3)
We recommend installing the appliance (Fig. 1, Rif.A) as close as possible to the delivery points to minimize heat loss along the pipes. Local regulations may provide for restrictions on installation in bath-rooms; 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 may be installed either vertically or horizontally (Fig. 2). To install it horizontally, rotate it clockwise so that the water pipes are at the left (cold water pipe at the bottom). Any other installation than that shown in (Fig. 2) is improper and prohibited.

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.
The appliance must not be supplied with water of hardness less than 12°F, or with especially hard water (greater than 25°F); we recommend installing a water softener, properly calibrated and controlled – do not allow the residual hardness to fall below 15°F.

• 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 (Fig. 2, Rif.B). On the other side of the “T” piece union screw the safety valve supplied (Fig. 2, Rif.A).

Safety group complies with the European standard EN 1487

• Some countries may require the use of hydraulic special safety devices; 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 appliance’s drain outlet must be connected to a drain pipe of diameter at least equal to the of the outlet itself, with a funnel to permit an air gap of at least 20 mm for visual inspection.
• Use a hose to connect the safety group to the mains cold water supply; fit a cock if necessary (Fig.2, Rif.D). In addition, a water discharge tube on the outlet (Fig.2, Rif.C) is necessary if the emptying tap is opened. When installing the safety device, do not tighten it fully down, and do not tamper with its settings. 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.

ELECTRICAL CONNECTION

• It is mandatory, before installing the appliance, to perform an accurate control of the electrical sys-tem 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 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 re-placing, use a cable featuring the

• same characteristics (type H05VV-F 3×1,5 mm2, 8,5 mm in diameter). The power cable (H05VV-F 3×1.5 mm2 dia. 8.5 mm) must be routed in the recess at the back of the ap-pliance to the terminal block (Fig. 7, Ref. M). Tighten down the

• terminal screws to connect the individual wires securely. Secure the power supply cable in place using the special cable clamps provided with the appliance. Use a two-pole switch conforming with national laws in force (contact gap of at

• least 3 mm, preferably equipped with fuses) to disconnect the appliance’s power supply.

• The appliance must be grounded with a cable yellow/green and longer than the phase cable) connected to the terminals marked (Fig.7, Rif. G).

• Before starting up the appliance, check that the power rating matches that given on the 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 3×1,5 mm2, 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, and tighten down the bolts not too much, if neces-sary ( Fig.5, Rif.C) and/or the rings (Fig.5, Rif.W).
• Power the appliance by actuating the switch.

MAINTENANCE (FOR QUALIFIED PERSONNEL)

All maintenance operations and service visits should be performed by a competent person (who have the skills required by the applicable norms in force).

• After removing the control panel, you can disconnect the connectors of the rod-carrying sensors and power board. Intervene on the rod carrying sensors (Fig. 7, Ref. K) by disconnecting the wires (Fig. 7, 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.

• The model have dry resistances (Fig. 4b, Rif. R), which can be replaced without emptying the device, because they are not in direct contact with water.

• To replace a malfunctioning heating element (identified with a tester) disconnect the cable
  (Fig. 4b, Rif. X) and undo the screw (Fig. 4b, Rif. V). Remove the damaged heating element and replace it. Remove the bolts (Fig. 5, Ref. C) and remove the flanges (Fig. 5, Ref. F). 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 their original positions (Fig. 7 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 (Fig. 6, Ref. Z) every time it is disassembled. CAUTION! Swapping the heating elements will cause the appliance to malfunction. Work on one element at a time, and only disassemble the second one after the first one has been reinstalled.

• Use only original parts from authorized service centres authorized by the manufacturer.

PERIODICAL MAINTENANCE

The magnesium anodes (Fig. 6, 6a Rif.N) must be replaced every two years or the warranty shall be voided (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 (Fig. 5, Rif. X) is inspected in the event of fault due to its obstruction. To inspect it remove the two rings (Fig. 5, Rif. W).
After routine or extraordinary maintenance, 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.

• 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 flowing 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.

OPERATION AND ADJUSTMENT OF THE OPERATING TEMPERATURE
The product is set to a temperature of 70°C for the 30, 50 and 80 l models and to 60°C for the 100 l model. The “ECO” function is active. In case of power shortages, or if the product is switched off using the ON/OFF button “ ”, the product memorises the last set temperature.
During the heating phase, slight noise may occur due to the heating of the water. Press the ON/OFF button “ ” to switch the appliance on.
Use the buttons to set the desired temperature to a value between 40°C and 80°C as shown on the display. During normal operation, the display will show the temperature reached by the water inside the product. During the heating phase, the status indicator (Fig. 8, Ref. 1) is red and turns blue once the set temperature is reached. If the water temperature drops, for example after a withdrawal, the heating function will be automatically activated.

HOT WATER LEVEL
The indicators on the sides of the display (Fig. 8 Ref. 2) allow to check the level of hot water inside the water heater, on a four-segment scale. While the temperature is being set, the indicators light up to en-able the user to visually check the set level.
During the heating phase the indicators light up gradually, indicating the increase in the temperature of the hot water inside the product, until the set temperature is reached.

ECO FUNCTION

• The “ECO” function is a software programme that automatically “learns” the user’s consumption levels, reducing heat dispersion to a minimum while maximising energy saving. The “ECO” software programme requires an initial
• memorisation  period that lasts one week, during which the product starts operating at the set temperature. At the end of this “learning” week, the software programme adjusts the water heating according to the user’s actual needs, which
• are automatically identified by the appliance. The product guarantees a minimum hot water reserve also when there are no water withdrawals.
• The learning process regarding the hot water requirements continues even after the first week.
• The process reaches its full efficiency after four weeks of learning.
• In order to ensure the program’s correct operation, the product should not be disconnected from the mains electricity.
• An internal memory ensures that the data will be stored for a maximum of 4 hours without electricity.
• After this time, all the acquired data will be deleted and the learning process will start from the beginning.
• To activate the function, press the “ECO” button, which will light up.
• In this mode, the temperature can still be selected manually, but adjusting its value will deactivate the ECO function. This function can be deactivated by pressing the “ECO” button, which will turn off.
• To reactivate it, press the “ECO” button again.
• To voluntarily delete the acquired data, press and hold the “ECO” button for more than 3 seconds. Once the reset process has been completed, the “ECO” button will flash quickly to confirm the deletion of the data.

BOOST FUNCTION
The BOOST function temporarily sets the set-point temperature to 80°C, bypassing the previous operating mode (if the ECO function is active, the auto-learning function will be temporarily suspended anwill resume automatically once the set-point is reached).
To activate or deactivate the BOOST function, press the corresponding buttos. If the function is activ, the correspondign LED will be lit. If the product is switched OFF using the ON/OFF button “ ”, if the “ ” “ ” buttons are pressed to change the set point or if a shut-off error appears, the BOOST function will be deactivated.

PROTECH FUNCTION
The “PROTECH” function activates for the product, an electronic system that protects against corrosion Orig-inmates by the water-metal contact, ensuring excellent longevity of the appliance’s tank in case of chemically aggressive water. The principle of operation is the following: the electronic circuit creates a difference in potential between the tank and the titanium electrode, thereby guaranteeing excellent protection of the tank, preventing corrosion due to the galvanic effect. For correct system operation, it is necessary to guarantee the permanent connection of the product to the electrical power mains.
In the presence of a malfunction of the function, the display will show the error code E04.
Also in the case of appliance downtime, turn the product off by the ON/OFF “ button, disconnect it from the electrical power mains. lf you wish to switch the electrical power supply off tor long periods of time, it is advisable to empty out all of the water contained in the appliance (see “Maintenance” paragraph) to ensure increased durability of the tank/resistance.

ANTI-FREEZE FUNCTION
The anti-freeze function automatically protects the appliance, preventing damages caused by very low temperatures, below 5°C, if the product is switched off during the winter season. We recommend leaving the product connected to the mains electricity, even in case of prolonged inactivity. Once the temperature rises to a safer level that prevents damages caused by ice or frost, the water heating function switches off again.
The function is enabled, but in case of activation it does not indicate whether the product is ON. When the product is switched off using the ON/OFF button “ ”, if the anti-freeze function is active the display will show “AF” (Anti-Freezing).

WEEKLY PROGRAM FUNCTION
The weekly program function can only be activated through the App.
Two different setpoint temperatures at two different times can be selected for each day of the week: the product will calculate the heating speed and, depending on the temperature, the best moment to start heating in order to reach the setpoint at the desired time.
Press the buttons to deactivate the function.

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 anti Legionella 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.
• To activate this function, simultaneously press and hold the ON/OFF “ ” and “ ” buttons for 3 seconds; the display will show “A1” for 4 seconds to confirm the activation.
