and subject to regular inspections and
maintenance.
In particular, the hardness of the water
supplied to the system, must never be
below 12° F.
Where fi lling water is aggressive (we
advise you to keep the pH between 6.6
and 8.5), ferruginous, or hard, use treated
water to prevent build-up, corrosion,
and damage to the system. We remind
you that even a slight quantity of
impurities in the water may decrease
the performance of the system.
The fi lling water used absolutely must
be treated in the case of high capacity
installations (high volumes of water)
or in the case of frequent additions of
water in order to maintain a constant
level of liquid in the system. In the event
that you need to carry out cleaning of
the installation, you must subsequently
fi ll the entire system with treated water.
Ensure that the maximum water supply
pressure level does not exceed 5 bar.
Otherwise, install a pressure reducer.
NOTE:
for the boiler installation, operation and
maintenance instructions, please see
the documentation supplied with the
boiler.
• The absence or incorrect installation
of the safety unit
• Safety unit installation that does not
comply with applicable standards, or
use of a damaged safety unit
• Changes made to the safety unit as a
result of hydraulics works
• Abnormal corrosion of hydraulic
components due to incorrect
connections (iron-copper direct
contact)
• Faulty electrical connection which
does not conform to applicable
installation regulations, incorrect
grounding, using cables with an
insuffi
cient
cross-section,
non-
adherence to the connection
diagrams provided
• Switching on the system before
hydraulic fi lling
The guarantee does not apply in
cases of insuffi
cient maintenance:
• Abnormal build-up on the heating
elements and the safety devices
• Lack of safety unit maintenance for
pressure reduction
• Frame subjected to aggression by
external agents
• Changes made to the original system
without advising the manufacturer
or use of non-original spare parts

System water characteristics
Ensure that the system is supplied with
water with a maximum hardness of 20°
F.
For areas where the water is particularly
limestone-rich, ensure that the use of
a softener does not in any way aff ect
the previous guarantees, provided
that the part is professionally installed
The warranty is only valid if the appliance
is installed by a qualifi ed technician.
Damage as a result of the following
causes void the guarantee:
Abnormal installation environment
conditions:
• Placing the internal unit outside the
home
• Placing the internal unit in a location
which is subject to bad weather or
frost exposure
• Supplying the system with rainwater,
well water, or with abnormally hard
water or water which is not compliant
with applicable regulations
•
Replacement installation of
systems and components with
manufacturing defects.
In the event of damage being
discovered on the system, it will be sent
to one of our Service Centres, once our
Technical Services have been advised.
Damage caused by incorrect installation,
transport, packaging and positioning
following collection by the distributor
will be the responsibility of the installer.
The repair or replacement of system
components can not in any way be
refunded, if it happened under any
of the following circumstances:
• Various damages caused by shocks
or electrical failures during handling
of the product, after it leaves the
production establishment
• Damage caused by water leaking
from the internal unit that is avoidable
through immediate product repair
• Damage caused by system exposure
to overvoltages
The warranty applies to internal unit
and external unit, only where the
hydraulic and electronic components
of both remain intact.
The guarantee does not apply
in cases where the installation
does not conform to applicable
regulations and standards, as well as
to professional standards, and, more
