Anti-legionella recommendations (European standard CEN/TR 16355) Information Legionella is a small bacterium, of stick-like form, and is found naturally in fresh water. Legionnaire's disease is a serious pulmonary infection caused by inhalation of the Legionella pneumophilia bacterium and other species of Legionella. The bacterium is frequently to be found in the plumbing of houses, hotels and water used in A/C and air cooling systems. The most effective measure against infection is to prevent the bacterium proliferating in water circuits. European standard CEN/TR 16355 provides guidelines for preventing the proliferation of Legionella in drinking water systems, without substituting applicable local legislation. General recommendations “Conditions favourable to the proliferation of Legionella”. The following conditions are favourable to the proliferation of Legionella:

• Water temperature in the range 25 - 50 °C. To reduce the proliferation of Legionella, the water temperature be kept with these limits to prevent them growing or reduce their growth to a minimum. If this is not possible, the drinking water system must be sanitised thermally;
• Stagnant water. To prevent water stagnating for a long time, the drinking water system must be flushed or made to run abundantly at least once a week;
• Nutrients, biofilms and sediment in the circuit, including boilers, etc. Sediment may promote the proliferation of Legionella and should be regularly eliminated from water storage devices, boilers and expansion/holding tanks (for instance, once a year). As regards storage heater like the present, if:

1) the appliance is switched off for several months at a time or

2) the water temperature is kept constant in the range 25 - 50°C,

the Legionella bacterium may grow inside the tank. If such circumstances, to reduce the proliferation of the bacterium, one must run a thermal sanitisation cycle. This cycle is suited to use in domestic hot water systems and complies with the guidelines for the prevention of Legionella given in Table 2 of standard CEN/TR 16355 (see below).

Remove the sediment from the storage heater as required by local conditions, but no less frequently than once a year. Thermal disinfection for 20 minutes at 60°C, for 10 minutes at 65°C or 5 minutes at 70 °C at all delivery points at least once a week. e The water temperature in the circulation circuit may not fall below 50°C. - Not required

This storage water heater is sold with a thermal disinfection cycle function not enabled for default; as a consequence, if, for any reason, one of the above said “Conditions for Legionella growth” could occur; it’s hardly recommended to enable such function rotating the knob up to maximum water temperature (>60°C). However, the thermal disinfection cycle does not kill all Legionella bacteria in the storage tank. It follows that if the water temperature setting is less than 55°C, the Legionella bacterium infection may reoccur. Caution:

the water temperature in the tank can cause immediate serious burns. Children, disabled persons and the aged are particularly at risk of burns. Check the water temperature before taking a bath or shower.

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. We recommend installing the appliance 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. The range of water heaters includes models set up to be assembled above or below the point of use (sink, basin or shower). The models intended to be assembled under the point of use are called "undersink". To facilitate maintenance, make sure there is a clearance of at least 50 cm inside the enclosure for access to the electrical equipment. Fix the supplied bracket to the wall with screws and dowels of adequate size for the type of wall. Hook the water heater to the bracket and pull down to make sure it is secured.

HYDRAULIC CONNECTION Hook up the water heater inlet and outlet with pipes or fittings that are resistant to the operating pressure and hot water temperature, which may reach and even exceed 80°C in normal operation. Do not employ materials not rated for such temperatures. Screw a T-fitting to the appliance's intake (blue collar). To this fitting, screw a drain cock (B fig. 1) of a type that can only be operated with a tool) on side and on the other, the overpressure device (A fig. 1). CAUTION For countries which have enacted European standard EN 1487, the overpressure device supplied with the appliance (if present) is non-conforming. The regulatory device must be calibrated to a maximum pressure of 0.7 MPa (7 bar) and include at least a cock, check valve and control, safety valve and hydraulic load cutout. 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 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 airgap of at least 20 mm for visual inspection to prevent damage or injury to persons, animals and property when the device operates; the manufacturer is not liable for any such consequences. Use a hose to connect the overpressure device to the mains cold water supply; fit a cock if necessary (D fig. 1). Fit a drain pipe to (C fig. 1) to handle circumstances in which the drain cock is opened. When installing the overpressure safety device, do not tighten it fully down, and do not tamper with its settings. It is normal that water drip from the overpressure safety device when the appliance is heating. For this reason one must install a drain, open to the air, with a continuously downwards sloping pipe, in an area not subject to subzero temperatures. If the mains pressure is close to the valve's setting, fit a pressure reducer as far away from the appliance as possible. If you decide to install mixer units (taps or shower), purge the pipes of any potentially damaging impurities first. 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 hardness 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 impurities. “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 Before working on the appliance, shut off mains power with its external power 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 mains power supply is rated for the heater's maximum power draw (refer to the nameplate) and that the electrical cables are suitably rated and regulatory. Multi-plugs, extensions and adapters may not be used. Do not use the plumbing, heating or gas pipes for grounding the appliance. If the appliance has a power cord which requires replacement, use a cable of equivalent type (H05VV-F 3x1 mm2, dia. 8.5 mm). The power cord (HO5 V V-F 3x1 mm2 dia. 8.5 mm) must be routed into the hole (F fig. 3) in the back of the appliance and connected to the thermostat terminals (M fig. 6). Use a two-pole switch conforming with CEI-EN (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 (T fig. 6). Before starting up the appliance, check that the power rating matches that given on the nameplate. If the appliance has no power cord, it can be installed in one of the following ways: - connection to mains with a rigid pipe (if the appliance has no cable clamp); - with a flexible cable (H05VV-F 3x1mm2, dia. 8.5 mm) if the appliance has 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 leaks from the flanges, tighten down the fittings (not too much!) if necessary (A fig. 4). Power up using the switch and in models with no switch, power up by turning the adjustment knob clockwise

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. Maintenance work may only be done by qualified technicians (in possession of the regulatory requisites). Before requesting for the Technical Assistance to intervene for a suspected fault, check that this is not caused by a temporary lack of water supply or power failure. Draining the appliance Make sure to drain the appliance when it is out of service or in an area subject to subzero temperatures. To drain the appliance, proceed as follows: - permanently disconnect it from its power supply; - close the cock, if present (D fig. 1), or the main domestic water system cock; - open the hot water tap (sink or bath tub); - open cock (B fig. 1). Replacing parts Disconnect the appliance from its power supply. Remove the enclosure to access the electrical equipment. To work on the thermostat, extract it from its mount and disconnect it from its power supply. To work on the heating element and anode, first drain the appliance. Use only original spare parts Scheduled maintenance The heating element (R fig. 5) should be descaled every two years to ensure it works properly. If you do not wish to use a liquid descaler, you can simply break off the deposit, taking care not to damage the heating element's cladding. The magnesium anode (N fig. 5) 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 it, remove the heating element and unscrew it from its bracket. 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, otherwise the. Reactivating the two-pole cutout If the water overheats excessively, a thermal cutout (CEI-EN compliant) trips to cut the electrical power supply to the heating element (both phases); contact the Service Centre if this occurs. Overpressure safety device 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. Thermoelectric models The instructions given in this manual also apply to thermoelectric models. However, such models must also be connected to the radiator pipes. Connect the upper radiator connector of the water heater to the radiator's up pipe, and the lower one to the down pipe, fitting two cocks at the same time. The lower cock, which is easier to access, is used to disconnect the appliance from the circuit when the radiator is not in use. USER INSTRUCTIONS

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

Recommendations - Do not place anything under the water heater which may be damaged by a leak. - If the water is not used for a long time: ➣ shut off power to the appliance by setting the external switch to "OFF"; ➣ close the water circuit cocks. - Water heated to over 50°C can cause immediate serious burns or even death. Children, disabled persons and the aged are particularly at risk of burns. Do not attempt to service or repair the appliance. Operation, setting the operating temperature Start up Start up the heater with its two-pole switch. In models with no switch, power up by turning the adjustment knob clockwise. The indicator lamp only remains on when heating up. The thermostat will automatically disconnect the resistance when the preset operating temperature is reached. Setting the operating temperature On models with external regulation, the water temperature can be set with the knob (M fig. 7) connected to the thermostat, as indicated on the device itself. USEFUL HINTS If the water delivery is cold, have the following checked: - is there power to the thermostat and terminal block? - are the heating elements working? If the water is boiling hot (steam is coming out of the taps) Shut off electrical power to the appliance and have the following checked: - thermostat; - the amount of scale on the boiler and heating element. If the hot water delivery is insufficient, have the following checked: - the mains water pressure; - the condition of the deflector on the cold water intake pipe; - the condition of the hot water pipe; - the electrical equipment. Water leaking from the overpressure safety device It is normal that some water drip from the device while the water is being heated. To prevent this dripping, install an expansion vessel on the delivery side. If the device continues leaking even while the water is not being heated, have the following checked: - the device's setting; - the mains water pressure. Caution: Never obstruct the device's outlet! NEVER ATTEMPT TO REPAIR THE APPLIANCE YOURSELF - ALWAYS HAVE THIS DONE BY A QUALIFIED TECHNICIAN.
