1. GENERAL INFORMATION
1.1 GENERAL WARNINGS
The manual is an integral and essential part of the product; it will be delivered to the user.
Carefully read the warnings contained in the manual because they supply important information
pertaining to installation, use and maintenance safety.
Preserve the manual with care for future consultation.
The installation must be carried out in conformity with the regulations in force and the manufacturer’s
instructions by professionally trained personnel. Professionally trained personnel means technicians
with a specific technical knowledge in the field of thermal installation components and those Service
Centers that are authorized by the manufacturer.
The manufacturer is not responsible for damages to people, animals and objects caused by an
incorrect installation.
After removing the packaging, make sure that the content is complete.
In uncertain cases, do not use the device and contact the supplier. The packaging elements must be
kept out of reach of children due to potential danger.
Before carrying out any cleaning or maintenance operations, disconnect the equipment from the
supply mains using the system switch a/o the special cut-off devices.
Do not obstruct the air intake grills and the air discharge heads.
If the equipment shuts down or fails, turn it off and refrain from carrying out any machine repairs or
direct interventions.
Contact professionally trained personnel only.
Product repairs must be carried out only by a Service Center that is authorized by the manufacturer
using original spare parts only.
Machine safety may be compromised if the previous instructions are not respected.
In order to guarantee the efficiency and correct functioning of the machine, routine maintenance
following the manufacturer’s instructions must be carried out by professionally trained personnel only.
If you decide to no longer use the machine, all parts that may cause danger must be made harmless.
If the machine is sold or transferred to another owner or if you move and leave the machine behind,
always make sure that the present manual stays with the equipment so that it can be consulted by the
new owner a/o installer.
Original accessories must be used for all devices with optional or kit accessories (electrical
components included).
This appliance should be used only for the purpose it was manufactured for.
Any other use should be considered incorrect and therefore dangerous.
Any contractual or extra-contractual responsibility of the manufacturer for damages caused by the
incorrect installation and use or the inobservance of the instructions supplied by the manufacturer is
excluded.
