IMPORTANT RECOMMENDATIONS
WARNINGS.
is device may only be used
by adult users whose physical,
sensory or mental abilities are
not impaired.
is instruction manual (User
section) and/or the operating
instructions should be read by
skilled technical staff before
using this appliance.
Children must be supervised
to ensure they do not play
with the appliance.
is appliance can be used by
children under the age of 8
and by persons with reduced
physical, sensory or mental
capabilities, or lack of experi-
ence or required knowledge
under the supervision of a
person responsible for their
safety or who is aware of the
safe use instructions and of
the risks they run. Children
must not play with the appli-
ance. Cleaning and mainte-
nance by the user must not be
carried out by unsupervised
children.
is appliance has been de-
signed to serve one residential
housing unit only (and simi-
lar) subject to assessment of
the energy requirement for
domestic hot water; it is not
a heating system pursuant to
the legislation in force.
INSTALLATION.
Warning: due to its weight
(from 80 to 111 kg depending
on the version), this appliance
must be handled with care
to avoid injury to persons or
damage to property and to
the product itself. Installation
must therefore be performed
taking into account the fol-
lowing instructions:
-install the appliance in a
frost-free room. e warran-
ty does not cover any appli-
ance breakdown caused by
excessive pressure due to the
safety valve blocking because
of ice.
-Ensure the oor on which the
appliance is to be installed is
suitable to withstand the
appliance's own weight and
that of the water content
(approximately from 197 to
270 litres, according to the
version). It is recommended
to perform a structural as-
sessment by the designer of
the dwelling.
-If the storage tank is mounted
on a false ceiling, under the
roof or above a living area, it
is mandatory to install a drip
tray to be connected to the
drain.
-Suitably aerate the installa-
tion room in the event the
appliance is to be installed in
a room and/or in a position
where the ambient temper-
ature is always higher than
35°C.
-In a bathroom, do not install
this product in volumes V0,
V1 and V2. Install the device
in the V2 volume if the di-
mensions allow it.
-is device is intended for
use up to a maximum height
of 2000 m.
-Position the appliance in an
accessible area and at such
a distance from the wall to
permit correct maintenance
/ accessibility (Parag. 2.1).
-Refer to the installation dia-
grams (Parag. 2.1).
Warning: failure to comply
with recommended installa-
tion procedures, especially
those related to the room
volume below the minimum
of 20 m3, may significantly
reduce system performance.
-It is recommended to pro-
vide suitable shut-o valves
on the hydraulic connection
to allow for any routine and
extraordinary maintenance
operations which might re-
quire emptying/filling the
water heater.
-In order to prevent any sta-
bility and safety issues, it
is obligatory to secure the
boiler to the oor, on a at
surface, using the fastening
anchors supplied.

HYDRAULIC CONNECTION.
It is mandatory to install a
safety device, set to be trig-
gered at 0.7 MPa (7 bars)
(not supplied with the water
heater), sized 3/4”, compliant
with standard EN1487 as
amended and added, and in
any case compliant with local
regulations in force: this safety
device is to be tted to the cold
water inlet of the water heater
and must be protected against
freezing.
e safety unit must be tted
with a discharge device (over-
pressure) to be operated regu-
larly to remove any limestone
deposits.
It must also be checked regu-
larly to ensure it is not blocked.
The pressure reducer (not
supplied as standard) is re-
quired when the water mains
pressure exceeds 0.5 MPa
(5 bars) and must be mounted
on the main water supply line.
e safety unit must also be
connected to an open drain
pipe, in a frost-free envi-
ronment, with a permanent
downward gradient, to re-
move any expansion water
from the heating process, or
drainage water from the water
heater.
The maximum operating
pressure of the heat exchang-
er circuit must not exceed
0.3 MPa (3 bars) and its max
temperature must not exceed
85°C.
To perform any discharge
operations of the water heater,
strictly adhere to the following
sequence:
-disconnect the appliance
from the electrical power
supply.
-Disconnect the appliance
from the mains water supply
(cold water).
-Open the hot water tap.
-Actuate the discharge device
of the safety unit.
WIRING.
Before removing the cover
of the water heater, always
ensure the power is discon-
nected, to prevent any risk of
injury due to electric shocks.
e following must be provid-
ed upstream of the electrical
system:
-a circuit breaker or 16A
multi-pole fuse with contacts
compliant with regulations
in force.
-A 30 mA dierential circuit
breaker.
Should the power cable be
found to be damaged for any
reason, it must be replaced by
the Aer-sales Support, and/
or in any case by skilled and
qualied sta.
The water heater must be
connected to earth according
to the methods set out by the
regulations in force.
A special terminal, suitably
marked is provided for the
specic purpose.
is manual is supplied jointly
with the water heater; in the
event of loss it may also be
obtained from the Authorised
area Support service or be
downloaded from the suitable
website.
