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 65°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, excluding horizontal models, is a device that must be installed vertically in order to operate correctly. Once installation 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 sun-rays, 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. We recommend installing the appliance as close as possible to the delivery points to minimize 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.

HYDRAULIC CONNECTION

Connect The water heater inlet and outlet with pipes or fittings that are resistant to the working pressure swell as to the temperature of the hot water that can usually reach and exceed 70ºC. We therefore advise against the use of materials that do not 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. 1, Rif. B). On the other side of the “T” piece union screw the safety valve supplied (Fig. 1, Rif. A).

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.1, Rif. D). In addition, a water discharge tube on the outlet (Fig.1, 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.

“GRAVITY DRAIN” CONNECTION
Specific taps must be used for this type of installation and the connection must be implemented as shown in the diagram in (Fig.2) .

With this solution, the water heater can work at any mains pressure and no type of tap must be connected on the outlet pipe, which acts as a vent.

ELECTRICAL CONNECTION
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 (type H05VV-F 2,5 mm2, 10,1 mm in diameter). The power cable (H05VV-F 2,5 mm2 dia. 10,1 mm) must be routed into the hole in the back of the appliance (Fig.3, Rif. F) and connected to the thermostat terminals (Fig.6, Rif.M). The appliance must be grounded with a cable (yellow/green and longer than the phase cable) connected to the terminals Marked (Fig.6, Rif.G). Finally, lock the power supply cable with the special cable clamp. 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. 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 2,5 mm2 section;
With a flexible cable (type H05VV-F 2,5 mm2, 10,1 mm in diameter), if the appliance is supplied with a cable clamp.

Testing and start-up of the appliance
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, tighten down the bolts not too much, if necessary. Power the appliance by actuating the switch.

MAINTENANCE (FOR QUALIFIED PERSONNEL)

All interventions and maintenance operations must be carried out by qualified personnel(in possession of qualification required by the regulations in force on the subject). Before calling your Technical Servicing Centre, check that the fault is not due to lack of water or power failure.

To access the control panel (Fig. 6, Ref. W), slide the lower panel to the left side as shown (Ref. 2), and check whether the cable (Fig. 6, Ref. Y) is disconnected from its housing. During reassembly, make sure that all components are put back in their original positions.

To work on the heating element, and the anode, first empty the appliance by closing the mains tap and allow the water to flow from inside the same through open the hot water tap.
Remove the 5 bolts (Fig. 4, Ref. A) then remove the flange outwards from the inside with a semi-circular movement.

The heating element is 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. We recommend replacing the flange gasket (Fig. 5, Ref Z). Use only original parts from authorized service centers authorized by the manufacturer.

MAGNESIUM CARTRIDGE
The Magnesium cartridge has to be replaced every 24 months to continue operating efficiently and to maintain warranty conditions.

PERIODICAL MAINTENANCE
The heating element (Fig. 5, Rif.R) 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 de scaler (in this case please read the safety data sheets of de scaling), you can simply break off the deposit, taking care not to damage the heating element’s cladding. The magnesium anode 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 the anode, take off the plastic anode cup that is the below part of the product, close to the inlet tube.
