ARISTON Cupid'o User Manual

GENERAL SAFETY INSTRUCTIONS

CAUTION!

1. This manual is an integral part of the product. Keep it with care with the appliance, and hand it on to the next user/owner in case of change of property.

2. Read the instructions and warning in this manual carefully, they contain important information regarding safe installation, use and maintenance.

3. The appliance must be installed and commissioned by a qualified technician in accordance with local legislation and health and safety regulations. All power circuits must be shut off before you open the terminal block.

4. DO NOT use the appliance for any other than its specified use. The manufacturer is not liable for damage resulting from improper or incorrect use or failure to observe the instructions given in this manual.

5. Incorrect installation can result in damage to property and injury to persons and animals; the manufacturer is not liable for the consequences.

6. DO NOT leave the packaging materials (staples, plastic bags, expanded polystyrene, etc.) within the reach of children - they can cause serious injury.

7. The appliance may not be used by persons under 8 years of age, with reduced physical, sensory or mental capacity, or lacking the requisite experience and familiarity, unless under supervision or following instruction in the safe use of the appliance and the hazards attendant on such use. DO NOT permit children to play with the appliance. User cleaning and maintenance may not be done by unsupervised children.

8. DO NOT touch the appliance when barefoot or if any part of your body is wet.

9. Any repairs, maintenance, plumbing and electrical hookup must be done by qualified technicians using original spare parts only. Failure to observe the above instructions can compromise the safety of the appliance and relieves the manufacturer of any liability for the consequences.

10. The hot water temperature is regulated by a thermostat which also acts as a re-armable safety device to prevent dangerous overheating.

11. The electrical hookup must be done as indicated in this manual.

12. If the appliance is equipped with a power cord, the latter may only be replaced by an authorised service centre or professional technician.

13. Do not tamper with the overpressure safety device, if supplied together with the appliance; trip it from time to time to ensure that it is not jammed and to remove any scale deposits. In countries which have enacted EN 1487, the appliance's intake pipe must be equipped with a safety device compliant with the said standard, calibrated to a maximum pressure of 0.7 MPa, including at least a cock, check valve, safety valve and hydraulic load cutout.

14. It is normal that water drip from the overpressure safety device and EN 1487 safety unit 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. Make sure to drain the appliance when it is out of service or in an area subject to subzero temperatures.

15. Make sure to drain the appliance when it is out of service or in an area subject to subzero temperatures.

16. Water heated to over 50° C can cause immediate serious burns if delivered directly to the taps. Children, disabled persons and the aged are particularly at risk. We recommend installing a thermostatic mixer valve on the water delivery line, marked with a red collar.

17. Do not leave flammable materials in contact with or in the vicinity of the appliance.

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 and other species of used in A/C and air cooling systems. The most effective measure against infection is to prevent the bacterium proliferating

Legionella

. The bacterium is frequently to be found in the plumbing of houses, hotels and water

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).

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.
