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.

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.

chapter "Technical information"p.54.
The installation must be carried out by the installer. There
is a risk of water leakage, electric shock or re if the instal-
lation is not performed correctly.
During the installation, it is necessary to observe the pre-
cautions mentioned in this manual, and on the labels
placed inside the equipment, as well as to adopt any pre-
caution suggested by common sense and by the Safety
Regulations in force in the place of installation.
Be sure to use the supplied or specied installation parts.
Use of other parts may cause the unit to come to lose,
water leakage, electrical shock, or re.
Failure to apply the indicated rules may cause malfunc-
tions of the appliances and relieves the manufacturer

count both purely technical requirements and any national/
local legislation in force.
The appliance is intended to be installed indoors.

19
INSTALLATION
Preliminary warnings
Avoid installing the unit near:
• narrow places where the sound level of the appliance can
be enhanced by reverberations or resonances
• environments with the presence of ammable or explo-
sive gases
• very humid environments (laundries, greenhouses, etc.)
• environments with aggressive atmospheres
• solar radiation and proximity to heat sources
Avoid placing the unit within 1 metre of radio and video
equipment.
Make sure that:
• the installation site of the unit must be chosen with the ut-
most care to guarantee adequate protection from shocks
and consequent damage
• the oor is able to support the weight of the appliance.
• the oor is not crossed by pipelines, load-bearing con-
struction elements or power lines
• the appliance must be installed in a position where it can
be easily serviced
Provide the following:
• a drain and a water supply nearby
• a compliant power supply nearby
2�10 Installation minimum distances
The clearance zones for the installation and maintenance of
the appliance are shown in the gure. Established spaces are
necessary to allow for normal cleaning and maintenance.
Make sure that there is sucient space to allow the pan-
els to be removed for routine and supplementary mainte-
nance operations.

Make sure that:
• it is levelled
• easy access is allowed to the hydraulic and electrical parts
2�12 Hydraulic connections
Preliminary warnings
The engineer is responsible for choosing the right water
lines and their size, in accordance with good installation
practices and the applicable law.
The hydraulic system is made by the installer and must be
carried out with reference to the diagrams in this manual
or on the website.
The hydraulic pipes connecting to the appliance must be
suitably sized for the actual water ow rate required by the
plant during operation. The water ow rate to the heat ex-
changer must always be constant.
The maximum permissible pressure drops must be
compared with the data shown in chapter "Pressure
drop" p. 38. If higher heads are required due to high
pressure drops in the plant, an external pump with respec-
tive buer vessel must be used.
Make sure that the quantity of water in the primary circuit
is greater than the minimum volume indicated in chapter
"Plant water content and minimum ow rate" p. 21, to
prevent the risk of ice formation during defrosting oper-
ations or continuous modulation of the compressor fre-
quency
It is important to note that the heat pump Control Panel
manages all the adjustments of the primary circuit (plant
and domestic hot water set-point, circulation pump, dy-
namic set control and auxiliary heater management).
Any regulation that foresees the management of the plant
with a control unit or a boiler conicting with these regu-
lations must be submitted to the manufacturer's technical
oce in advance for approval otherwise the warranty will
be invalidated.
If the appliance is connected in parallel with a boiler, make
sure that the temperature of the water circulating in the
heat pump does not exceed 60 °C during operation.
