INSTALLING NORMS (for the installer)
This product, excluding horizontal models (Table 1), is a device that must be installed vertically in order to oper-
ate 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 fi rst 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 appli-
ance 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:
- Damp: 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 sud-
den voltage jumps.
In the case of walls made of bricks or perforated blocks, partition walls featuring limited static, or masonry diff erent in
some way from those stated, you fi rst 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 fi lled with water.
Fastening hooks with a diameter of at least 12 mm are recommended.
We recommend installing the appliance (A Fig. 1) 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. 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's inlet and outlet with pipes or fi ttings 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, nor with especially hard water (greater than
25°F); we recommend installing a water softener, properly calibrated and controlled - do not allow the residual hard-
ness 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 (B Fig. 2). On the other side of the "T" piece union
screw the safety valve supplied (A Fig. 2).
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; fi t a cock if necessary (D fi g. 2). In addition, a water discharge tube on the outlet C Fig. 2 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.
