Ariston FLECK NILO Instructions For Installation, Use, Maintenance page 16

The appliance is conforming with international electrical safety standard IEC 60335-1;
IEC 60335-2-21.
The CE marking applied to the appliance certifies that it conforms with the essential requirements of
the following European Directives:
- LVD Low voltage directive: EN 60335-1, EN 60335-2-21, EN 60529, EN 62233, EN 50106.
- EMC Electromagnetic compatibility: EN 55014-1, EN 55014-2, EN 61000-3-2, EN 61000-3-3.
- ROHS 2 directive: EN 50581.
- ErP Energy related Products: EN 50440.
This product is in conformity with REACH regulations.
This product can be installed vertically (installation recommended by the manufacturer) and hori-
zontally. This product 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 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 ma-
sonry 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.
We recommend installing the appliance (Fig. 1, Rif.A) as close as possible to the delivery points to
minimise 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 clear-
ance of at least 50 cm inside the enclosure for access to the electrical equipment.
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.
