INSTALLING NORMS (for the installer)

CAUTION Observe all general warnings and safety standards listed at the begin-

ning of this text in full; all such instructions are obligatory.

The appliance must be installed and commissioned by a qualied technician in accordance with estab-

lished regulations and local health and safety regulations.

This product, excluding horizontal models (Table 3), is a device that must be installed vertically in order to ope-

rate 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 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 appliance

according to the applicable norms in force.

- Read the instructions provided on the packaging label and on the appliance data plate.

Installing the appliance

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 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 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 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 elec-

trical equipment.

Hydraulic connection

Connect the water heater’s inlet and outlet with pipes or 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.

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 g. 2). On the other side of the “T” piece union

screw the safety valve supplied (A g. 2).

CAUTION! For those nations that have taken on European norm EN 1487, the pressure safety device pro- vided

with the product does not comply with that norms. According to the norm, the device must have a maximum pres-

sure of 0.7 MPa (7 bar) and have at least: a cut-off valve, a non-return valve, a control mechanism for the non-return

valve, a safety valve and a water pressure shut-off device. 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 device relief must be connected to a relief pipe that has a diameter at least identical to the one of the equipment

connection. Use a funnel that creates an air gap of at least 20 mm and allows visual checks so that no personal injury,

property damage or damage to animals will occur in case of safety device enabling. The manufacturer will not be held

responsible for such damage. Connect the inlet of the pressure safety device to the cold water system using a exible

pipe, using a cut-off valve if necessary (D g. 2). In addition, a water discharge tube on the outlet C g. 2 is necessary

if the emptying tap is opened.

When tightening the pressure safety device, do not over tighten and do not tamper with it. It is normal for water to trickle

from the tap during the heating phase; for this reason, 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
