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 qualified personnel.
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 qualified installer companies are authorised to

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 qualified 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, disconnect the power
supply to the unit and the seawater pump and close

1�2�1 S pecificwarningsforR32
This document contains only some of the warn-
ings related to the refrigerant R32. For more com-
prehensive information, carefully read the safety
data sheet available from the dealer.
All precautions concerning the treatment of the refrig-
erant must be observed following the regulations in
force.
The unit uses environmentally friendly R32 refrigerant
gas, with a Global Warming Potential (GWP) = 675. Do
not release R32 gas into the atmosphere.
R32 refrigerant gas is slightly flammable and odourless.
If refrigerant gas escapes, aerate the room abundantly
and leave. Call the Technical Assistance Service or pro-
fessionally qualified personnel as soon as possible and
do not intervene on the appliance yourself.
When refilling the system after any leakage of R32 re-
frigerant gas, make sure that no foreign substances
enter the circuit. The presence of air or other foreign
substances inside the refrigerant circuit can cause the
system to increase pressure or rupture and cause inju-
ries to persons.
Avoid proximity to sources of ignition in continuous
operation (open flames, gas appliances, electric stoves,
lighted cigarettes, etc.).
This unit contains fluorinated greenhouse gases cov-
ered by the Kyoto Protocol. Maintenance and disposal
operations must be carried out by qualified personnel
only.
