IMPORTANT: MAKE SURE THAT THE NUTS ARE PROPERLY TIGHTENED.
In the case of walls made of bricks or perforated blocks, partition walls with limited staticity, or masonry
different to that specified, a preliminary static check must be carried out on the supporting system. The
wall-mounting fastening hooks must be capable of supporting a total weight three times superior to the
weight of the water heater when it is filled with water.
The appliance should be installed as close as possible to the point of use to limit heat dispersion along
the piping. Local regulations may impose restrictions for installation in bathrooms; in this case, the
minimum distances specified in the applicable regulations must be observed.
To facilitate maintenance activities, leave a gap of about 50 cm around the cover to access the
electrical components.
PLUMBING CONNECTION
Connect the water heater inlet and outlet to pipes or pipe fittings which are resistant to the operating
pressure and temperature of the hot water, which could at times reach – and even exceed – 90°C. We
advise against the use of materials which cannot withstand such high temperatures.
:
WARNING
the manufacturer recommends a minimum water hardness without which the tank will
not be sufficiently protected. When the water is particularly hard, a water softener should be used.
Refer to the WATER HARDNESS AND CONDUCTIVITY TABLE.
1. The operating pressure is indicated on the water heater's data plate.
2. Screw a "T" fitting, identified by a blue collar, onto the appliance's water inlet pipe. On this fitting tight-
en a tap on one side for draining the water heater that can be adjusted only with a tool (Figs. 1/2, Ref.
F), and on the other side tighten a safety assembly conforming to the applicable national regulations
(Figs. 1/2, Ref.C).
3. WARNING! It is forbidden to use "PER"-type synthetic materials for the connection: risk of flooding.
To connect the appliance to the plastic "PER" pipe of the existing system, attach a copper pipe at least
50 cm long on the outlet (hot water) to prevent possible damages.
The connection of a water heater to copper pipes must be made using a dielectric coupling. Dielectric
couplings are available as an optional or standard feature, depending on the model purchased. NOTE:
If you have only one dielectric coupling, it must be connected to the hot water outlet.
4. When the network's input pressure is greater than 4.5 bar, a pressure reducer should be installed
upstream of the safety assembly.
5. If the water systems have the following features:
• small pipes;
• taps with mixer or ceramic plate;
a "ram stabilising" device or a domestic hot water expansion vessel suitably sized for the system must
be installed as close as possible to the taps.
SAFETY ASSEMBLY CONFORMING TO THE EN 1487 EUROPEAN STANDARD
Certain countries may require the use of specific safety devices, in line with local legal requirements; it is
the responsibility of the qualified installer charged with installing the product to assess the correctness
and suitability of the safety device used. It is forbidden to fit any shut-off device (valves, stopcocks etc.)
between the safety device and the water heater itself. The device's drain outlet must be connected to
a discharge pipe with a diameter at least equal to that used to connect the appliance, through a funnel
ensuring a minimum 20 mm air distance that can be checked visually. Use a flexible pipe to connect the
safety assembly inlet to the cold water system pipe, using a shut-off valve if necessary (Figs. 1/2, Ref. D).
Additionally, a water discharge pipe must be fitted to the outlet in case the drainage tap is opened When
tightening the safety assembly, do not force it into its stop position and avoid tampering with it. If the
mains pressure is close to the calibrated valve values, a pressure reducer must be installed as far from
the appliance as possible. Should you wish to install the mixer units (taps or shower), drain any impurities
from the pipes as they could cause damage.
ELECTRICAL CONNECTION
Before installing the appliance, the electrical system must be thoroughly inspected to verify that it
conforms to the applicable safety regulations, that it is adequate for the water heater's maximum
