Guarantee conditions
Ariston offers you a warranty of 2 years (3 years on the compressor
of the outdoor unit) from the commissioning of your system NIMBUS
S. This warranty covers the replacement of parts recognized as de-
fective, with the exception of damages occurred to the components
during installation and commissioning.
This warranty is subject to the execution of a regular maintenance
carried out by a qualifi ed technician, who will inspect, clean and make
appropriate adjustments on the system at least once a year, as indica-
ted by the Ministerial Circular of 09.08.78.
The repair or replacement of components during the period of vali-
dity of the warranty offered by the manufacturer do not result in a
renewal of the warranty.
The warranty offered by the manufacturer will not be considered valid
if the system is not rightly installed as well as in cases where the mal-
functioning of components is due to an improper use of the system or
to an inadequate maintenance of the same.
The warranty is valid just if the installation and subsequent mainte-
nances were performed in a workmanlike manner, in accordance with
the rules in force and following the instructions on the Installation
Manual and carried by a qualifi ed technician.
The warranty offered by the manufacturer does not cover the fol-
lowing situations:
• Damages to the components due to not allowed modifi cations of
the system, from inadequate or irregular water pressure, from unu-
sual quality features of the water (eg limestone, dirt ...) or from the
application of not allowed supply voltages
• Installation and subsequent maintenance operations are not carried
out by a qualifi ed technician
