Installing The Appliance; Hydraulic Connection - Ariston VEUS EVO WIFI 30 Manual De Instrucciones

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 qualified technician in accordance
with established regulations and local health and safety regulations.
The appliance heats water to a temperature below boiling point. It must be linked up to a mains water sup-
ply 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.

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 first need to carry out a preliminary static check of the support-
ing 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 (Fig. 3) 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.
Multi position installation
The product can be installed both vertically and horizontally (Fig. 2). During horizontal installation, rotate the
appliance clockwise so that the water pipes are located to the left (cold water pipe at the bottom).

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.
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).
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 pressure 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.
