2 COMPONENTS INSTALLATION
2.1 - CABIN CONDITIONER: HOW IT WORKS
When in cool mode ( ummer) the refrigerant circuit takes the
heat from the ambient air and gives it to the sea water. When
in heat mode (winter) the heat is taken from the sea water
which cools down and it is given to the ambient air which
warms up. With sea water below 10° C, the efficiency of the
unit in heat mode drops so much that we do advise against its
use. Units with electrical heating instead of reverse cycle are also available.
Cool and heat position, thermostat knob for temperature setting and fan
selector are available on the control panel which shall be installed in the air-
conditioned ambient at a max distance of 3 m from the evaporator.
MAX
3mt
2.2 - LOCATION
A.- The unit is engineered to draw directly the ambi-
ent air, then the unit should be installed in one of the
cabins to be conditioned (only the evaporator assy in
case of Split models).
B.- The treated air (blown by the fan) should be con-
nected to one or more delivery grills by means of flex-
ible ducts or using a yacht structure as a duct. Duct
must be properly insulated.
MIN
C.- Treating the ambient air means the separation of
condensate produced by air humidity. His conden-
sate must be drained and discharged over board; this
means that the unit should be installed at a certain
level to be connected to an outlet port, considering
that the condensate hose must have a minimum
heeling.
The refrigerant -
sea water heat
exchanger has
two 16 mm hose
fittings to be con-
nected to the
water circuit by
means of an
adequate rubber
or plastic hose. The flow sense is marked with arrows; anyhow the water
enters from the bottom coil of the heat exchanger and goes out from the top
outlet. Hose routing should avoid siphoning which will prevent the pump to
prime. The over board outlet port should be as low as possible but above the
water line: this to limit the water discharge noise and to avoid horizontal jets.

2 COMPONENTS INSTALLATION
E.- The unit is linked to the electrical connections box
with a 1 m long cable. So around the unit (compres-
sor assy for Split models) there should be enough
space for the box installation in a way to easy electri-
cal connections and maintenance.
F.- The thermostat bulb and the air filter shall be
installed on the refrigerant-ambient air heat exchang-
er (evaporator). It is necessary to leave enough
space at the side of the unit for periodical mainte-
nance.
G.- The maximum distance between unit and control
panel is 3 m both for the thermostat capillary and for
the connecting cable.
2.3 - INSTALLATION
The air-conditioner shall be installed using the stain-
less steel brackets supplied with it. It is better to use
a silent block mounting, if you install the compressor
in a cabin. It is also important not to force on the
cable linking the unit to the connection box.
Neoprene
2.4 - CONDENSATE DRAIN
The condensate discharge hose
should be connected to the 19 mm
drain nipples of the pans.
2.6 - BULB THERMOSTAT - C318
The thermostat bulb should be fastened to the refrigerant-ambient air heat
exchanger by means of two plastic fasteners. The bulb shall not touch the heat
exchanger fins as the direct contact will influence the thermostat set. The ther-
mostat feels only the return air. In particular situations it is possible to install the
bulb not directly on the exchanger, but in the room to feel its temperature using
the plastic plate supplied with the control panel.

2 COMPONENTS INSTALLATION
2.7 - AIR FILTER - C319
The unit draws air through the refrigerant-ambient air heat exchanger which has arrow aluminium fins. These
fins so close would get soon clogged because of dust and dirty if not installed directly on the exchanger as
shown in the drawing below. The air filter needs periodical maintenance and must be accessible for service.
2.8 - ELECTRICAL CONNECTION
The unit is already connected to the electrical connection box and doesn't need any other connection. For
complete schematic of electrical connections, see chapter 4.
2.9- SEA DISTRIBUTION CIRCUIT (vedi anche esempi a pag. 23 )
2.9.A - Suction 2.9.B - Air delivery
The unit draws air through one or more grills of ade-
quate dimensions. Minimum dimensions of return
grill are 244x244 regardless to unit capacity. The
return air should be straight to the unit: if return air
ducting is needed, please contact our technical serv-
ice.
The unit efficiency is strictly related to the air flow.
Thus it is important to have an air distribution without
weak points, keeping the original suggested diame-
ter, and not exceeding the suggested duct length.

2.9.C - Compact - Split with EV evaporator
The unit is supplied with a plastic fan-duct adaptator.
From this, the circuit goes to plenum and one or more
grills. The main duct diameter should meet the following
table:
The fan can be rotat-
ed of 90° to adapt
the air-conditioner to
a shallow installation
with reduced height.

2 COMPONENTS INSTALLATION
2.10 - ELECTRICAL CONNECTION BOX
The connection box has the following functions:
1- Electrical connections:
- From mains supply
- To compressor-fan assembly
- To control panel
- To sea water pump
2- Safety control monitoring and compressor start delay (optional: see 4.6).
3- Power relay for compressor, reverse cycle valve or electrical heating.
4- 3 speed fan supply.
5- Compressor supply (start relay, run and start capacitors).
2.10.A - LOCATION
The connection box must be installed vertically on
a bulkhead near the conditioner unit to which is
linked with 1 m long cables. Cables should enter
from bottom side and should be fastened by
means of plastic strippers.

2.10.B - INSTALLATION
The connection box has four holes in the base to
be used for fastening screws.

2.11- REMOTE PANEL
The control panel has the following functions:
A.- Start and stop
CONDIZIONAMENTO ESTIVO : premendo il tasto
SUMMER COOLING: Pushing the "COOL" button with ice
star mark.
WINTER HEATING: Pushing the "HEAT" button with
orange sun mark.
To stop the unit you must push the buttons "COOL" and
"HEAT" together.
B.- Setting of room temperature by thermostat
(TEMP).The thermostat has a 3 m long capillary with a
bulb, which must feel the return air (it must not touch the
evaporator fins).
C.- Adjusting the fan speed ( 3 speeds available )
Important: the low speed is selected pushing the two but-
tons "Max" and "Med" together.
2.11.A - LOCATION
When positioning the panel, one must consider that the
panel should be connected to the electrical box with the 3
m long cable and the thermostat bulb should be fastened
to the unit. If necessary, the bulb can be installed not
directly on the exchanger, but in the room. Anyway, it must
sense the ambient temperature. The bulb can be fixed
using the plastic plate supplied with it.
2.11.B.- INTERCHEANGEBLE BEZEL
The bezel supplied with the panel is black.
2.11.C - INSTALLATION
The panel is for flush installation and needs a cut out as
shown here on the right:
WARNING: The panel is connected to mains supply. It is absolutely necessary that,
when installed the back side of the panel, shall not be normally accessible. A plastic
cover is available on request in order to protect the back of the panel if accessible,
therefore dangerous.
