1�4 General warnings
This instruction manual forms an integral part of the de-
vice and therefore must be carefully preserved and must
ALWAYS travel with it, even if you transfer the device to an-
other owner or relocate it to other premises. If the manual
gets damaged or lost, download a copy from the website.
Read this manual carefully before proceeding with any
operation and follow the instructions in the individual
chapters.
All personnel involved must be aware of the operations
and dangers that may arise when beginning all unit instal-
lation operations.
Specic warnings are given in each chapter of the docu-
ment and must be read before starting operations.
Installation performed outside the warnings provided in
this manual and use of the appliance outside the pre-
scribed temperature limits will invalidate the warranty.
The installation and maintenance of climate control
equipment could be dangerous because there is pressur-
ised refrigerant gas and live electrical components inside
the appliances. The installation, initial start-up and subse-
quent maintenance phases must be carried out exclusive-
ly by authorised and qualied personnel (see rst start-up
request form enclosed with the appliance).
Any contractual or extra-contractual liability for damage
caused to persons, animals or property, due to installation,
adjustment and maintenance errors or improper use is ex-
cluded. All uses not expressly indicated in this manual are
not permitted.
Only qualied installer companies are authorised to in-
stall the device. After having completed installation, the
installer will issue a declaration of conformity to the plant
manager, as required by the applicable standards and the
guidelines provided by contractor's instruction manual
supplied with the device.
First start-up and repair or maintenance operations must
be carried out by the Technical Assistance Centre or by
qualied personnel following the provisions of this man-
ual.
Do not modify or tamper with the appliance as this can
lead to dangerous situations.
Use suitable accident-prevention clothing and equip-
ment during installation and/or maintenance operations.
The manufacturer is not liable for the non-observance of
the current safety and accident prevention regulations.
In the event of water set the master switch of the plant to
"o" and close the water taps. Call the authorised Tech-
nical Assistance Centre or professionally qualied person-
nel as soon as possible and do not work on the appliance
yourself.
In case of replacement of parts, use only original parts.
The manufacturer is not responsible for damages to per-
sons or property caused by failure to follow the instruc-
tions in this manual.
The manufacturer reserves the right to make changes to
its models at any time to improve its product, without
prejudice to the essential characteristics described in
this manual. The manufacturer is not obliged to add such
modications to machines previously manufactured, al-
ready delivered or under construction.
This document is restricted in use to the terms of the law
and may not be copied or transferred to third parties with-
out the express authorization of the manufacturer.
Specic warnings for R410a
Do not release R410a into the atmosphere. R410a is a
uorinated greenhouse gas, covered by the Kyoto Proto-
col, with a Global Warming Potential (GWP) of 2088.
When installing or rearranging the system, make sure that
so substances (e.g. air) other that the specic refrigerant
(R410a) enters into the refrigerant circuit (the presence of
air and other foreign substances in the refrigerant circuit
could cause abnormal increase of pressure or breakage in
the system, with consequent injury to people.

GENERAL
1�5 Basic rules of security
Please keep in mind that the use of products powered by
electricity and water call for operators to comply with certain
essential safety rules:
The use of the appliance to children and unassisted disa-
bled persons is prohibited.

1�7 Identication
The appliance can be identied by the rating plate.
Packaging plate
Shows the identication data of the device.
Technical rating plate
This shows the technical and performance specications of
the appliance.
According to EU Regulation No. 517/2014 concerning
certain uorinated greenhouse gases, it is mandatory to
indicate the total amount of refrigerant present in the in-
stalled system. This information can be found on the rat-
ing plate of the combined outdoor unit.
Tampering with, removal of, or lack of identication plates
will not allow for the safe identication of the product by
its serial number and therefore invalidates the warranty.
