Specic warnings are given in each chapter of the docu-
ment and must be read before starting operations.
All personnel involved must be aware of the operations
and dangers that may arise when beginning all unit in-
stallation 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 pres-
surised refrigerant gas and live electrical components
inside the appliances. The installation, initial start-up
and subsequent maintenance phases must be carried
out exclusively by authorised and qualied personnel
(see rst start-up request form enclosed with the ap-
pliance).
Any contractual or extra-contractual liability for damage
caused to persons, animals or property, due to installa-
tion, adjustment and maintenance errors or improper
use is excluded. All uses not expressly indicated in this
manual are not permitted.
Only qualied installer companies are authorised to
install 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
manual.
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 opera-
tions. The manufacturer is not liable for the non-ob-
servance of the current safety and accident prevention
regulations.
In the event of liquid or oil leaks, set the master switch
of the plant to "o" and close the water taps. Call the
authorised Technical Assistance Centre or profession-
ally qualied personnel as soon as possible and do not
work on the appliance yourself.
In case of replacement of parts, use only original parts.
The manufacturer reserves the right to make changes
to its models at any time to improve its product, with-
out prejudice to the essential characteristics described
in this manual. The manufacturer is not obliged to add
such modications to machines previously manufac-
tured, already delivered or under construction.

solar radiation and proximity to heat sources
20
INSTALLATION
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

ance.
the oor is not crossed by pipelines, load-bearing
construction 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
Preliminary warnings for R32
The appliance must be installed in well-ventilated
rooms with a minimum oor area as indicated in the
Minimum oor area table according to the total refrig-
erant charge in the circuit.
The refrigerant charge means the total charge of
thecircuitgivenbythesumofthefactorycharge
andanyadditionalcharge.
Refer to the rating plate on the paired outdoor unit for
the amount of refrigerant gas loaded in the unit.
If the appliance is located in a poorly ventilated place,
precautions must be taken to prevent stagnation in the
event of leakage of refrigerant to avoid creating a risk
of re or explosion.
The appliance must be placed in room where there are
no open ames continuously in operation (e.g. a gas
appliance in operation) and no sources of ignition (e.g.
an electric heater in operation).
Any ventilation openings must be kept free of obstacles.
Perform the following checks:
carry out safety checks to ensure that the risk of com-
bustion is minimised
avoid working in conned spaces
delimit the area around the workspace
ensure safe working conditions around the area by
controlling ammable material
