1�2 General warnings
 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.
 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, disconnect the power
supply to the unit and the seawater pump and close
the water taps. Call the authorised Technical Assistance
Centreorprofessionally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.
 During the cold period, if the unit is not in use, empty
all hydraulic circuits and the seawater condenser to pre-
vent freezing.
 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-

1�2�1 SpecicwarningsforR32
 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ammableandodourless.
 If refrigerant gas escapes, aerate the room abundantly
and leave. Call the Technical Assistance Service or pro-
fessionallyqualiedpersonnelassoonaspossibleand
do not intervene on the appliance yourself.
 Whenrelling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ames,gasappliances,electricstoves,
lighted cigarettes, etc.).

Preliminary warnings
 To allow maintenance or repair operations, each hy-
draulic connection must be equipped with the respec-
tivemanualshut-ovalves.
 Before connecting the piping, make sure that it do not
contain stones, sand, rust or foreign matter that could
damage the plant.
 The minimum nominal diameter of the connect-
ing pipes must be 3/4" (19 mm). Keep in mind that
undersized piping determines malfunctions and/
or loss of heating and cooling performance.
 The connection piping must be suitably supported so
as not to bear on the appliance with its weight.
 Flush the plant thoroughly before connecting the
unit. This cleaning process removes any residue, such
as welding drops, slag, rust or other fouling from the
pipes. These substances may otherwise settle inside
and cause the appliance to malfunction.
 It is necessary to install a ltration system at the
inlet of the appliance in an area accessible for
maintenance, in order to protect the appliance
from impurities in the water.
 Operatingtheunitwithoutthewaterlterinstalledand

cuit running.
 The sea water electric-pump is needed to circulate the
amount of water required in the heat exchanger.
 The pump should be installed in a sound insulated en-
vironment.

 It is necessary to install a ltration system at the
inlet of the appliance in an area accessible for
maintenance, in order to protect the appliance
from impurities in the water.
3�14 Condensation drain preparation
This appliance is complete with a tray for collecting the
condensation produced during operation, which must be
channelled to a suitable place for drainage.
The size and positioning of the drainage tube are shown
below.
3�14�1 Preliminary warnings
 The condensate must be discharged in the bilge or in
a special tank.
 If the line ows into a container (e.g. a tank), do not
close the container hermetically and avoid immersing
the draining pipe into the water.
 Since while operating the air conditioner sucks and
then creates a slight vacuum in the environment, the
drain pipe that goes directly or in the bilge or in a tank,
it could suck it up and bring unpleasant smells into the
cabin. To avoid this, it is appropriate to make a trap for
blocking the air.
 When connecting the condensation drain, be careful
not to squeeze the rubber duct.
 The direct discharge at side is not recommended be-
cause of sucking bad smells from the outside caused by
the exhaust gas of its own or other engines.
 Do not discharge directly to the side.
