3 INSTALLATION OF THE COMPONENTS
3.1 - FUNCTIONING OF THE AIR-CONDITIONERS
During the cooling cycle, the refrigerant circuit takes the ambient air
away and to make it over the sea water (CO models).
It is possible to select the functioning cycle, the desired temperature and
the fan speed from a remote control panel that can be installed in the air-
conditioned room. For the specific distances, refer to the directions of the
remote control panel (page 149).
Choosing the unit position, it is necessary to consider the following elements:
1 - the accessibility to the air filter for the cleaning;
2 - the necessary space for the fastening of the provided clamps (figure 1.8 - page 8);
3 - the connection of the condensation drainpipes (figure 2.8 - page 8);
4 - since the fan rotates, it is necessary to choose the best position to connect it to the air duct. Then,
block the fan in the chosen position;
5 - the passing of the sea water circuit pipes;
6 - the passing of the electrical connection wires and the easy access to the electrical box.
Position the pipe-tightening clamps of the water system so that once arranged the unit, it is possible to
tighten the screws. Instead of the clamps we suggest to use all stainless steel components.
3.2 - ARRANGEMENT - General notes
Version with standard mechanical panel

C - The exchanger system takes away the ambient
air. The side with the filter mustn’t be in line with the
aspiration grill, as in the picture 1.6. It can have
have also a different position (see the picture 2.6).
The second solution is the best one thanks to the
best sound isolation of the system.
3.3 - PLACING
A.- The unit has been
designed to take the
ambient air directly
away. It must be
installed in a room
that must be condi-
tioned.
B.- The conditioned air (from the fan) must be piped towards one or more grills through flexible
pipes or through isolated ducts of suitable section in the boat structure.

3 INSTALLATION OF THE COMPONENTS
E.- The air-conditioner is connected to the electrical
box through cables of different lenght. So there must
be an accessible space (next to the compressor unit
for SPLIT models) to install the electrical box.
F.- The thermostat bulb and the aspiration filter must
be mounted on the air-refrigerating gas exchanger.
This side must be accessible for the filter mainte-
nance.
G.- The maximum distance between the control panel
and the electrical box is 3 m both for the thermostat
capillary and for the connection cable.
3.4 - THERMOSTAT BULB
The thermostat bulb must be fastened to the air
exchanger by means of special latches.
The bulb must keep separated from the exchanger
because it must be influenced only by the sucked up
air, but not by the refrigerating circuit. Sometimes
you can install the bulb not directly on the exchan-
ger but in the room, so that it is sensitive to the ambi-
ent temperature. To fasten the bulb to the wall, you
can use the special plaque.

COMPACT and SPLIT QUATTRO models
page 8 www.climma.it
3.5 - FASTENING
The fastening must be executed as indicated.
3.6 - CONDENSATION OUTLET
The air-conditioning determines the separation of
the condensation water due to the humidity of the
conditioned air. This condensation must be dis-
charged in the bilge or in a special tank and then by
means of a self-priming pump in the sea.
The water condensation
outlet pipe must be
linked to the rubber-
holders of 19 mm on the
condensation collection
basin.
Each unit is endowed with two out-
lets, as you can see in the picture
above.
If the condensation discharge pipe for exigencies
of installation must be long, it is better to use the
special “L” connection. You must avoid such an
installation as you can see in the picture 1.8
because the condensation water can stop and flow
back to the collection basin because of the boat
rocking.
The direct bulkwark outlet is not the best solution: in
fact, it can suck up unpleasant smells due to the
exhaust emissions of its own or of other engines.
Make reference to the safety regulations of the
different countries

Since during the operating the air-conditioner sucks
up and causes a light vacuum in the room, the con-
densation outlet pipe can suck up from the pilge or
the special tank unpleasant smells that can spread in
the cabin. To avoid this possibility, it is possible to
create a siphon (A) as you can see in the picture 1.9
to stop the air.
To check the actual effi-
ciency of the condensa-
tion outlet, pour some
water in the basin.
3.8 - AIR FILTER
The air-conditioner sucks up the ambient air through an air-refrigerating gas exchanger endowed with many
aluminium tongues. They would soon become obstructed because of powder and filth. That’s why you can
mount the air filter directly on the exchanger (as you can see in the picture). The filter must be easily taken off
to clean or replace it.

3.9- AIR CIRCULATION SYSTEM (see examples on page 12)
3.9.A - Sucking up
The ambient air is sucked up through one or more
grills of suitable dimensions. The minimum dimen-
sions are 244x244.
(To canalize the air flow back, call the technical
assistance).
min 244 x 244
3.10.B - Air circulation
3.11.B - Air ducts
The efficiency of the installation depends on the air
volume. So it is important to avoid narrow passages
in the air circulation system, keeping the original
diameter dimensions and using short pipes.
The isolated ducts must not be bent so that the air
can circulate currently. Cut out the unuseful lenght.

3.12.C - COMPACT - SPLIT QUATTRO
The fan must be linked by means of a duct to the air
distribution system, that can be constituted of one or
more grills and corresponding plenums. The main
duct diameter must not be inferior to the diameter of
the fan fittings.
The fan can be turned of 90° in case of installation of limited
height.
Example of a Compact installation:
a plenum for air-conditioning two
cabins.

3.14- MECHANICAL CONTROL PANEL
3.15- DIGITAL CONTROL PANEL VEGA MKII
By means of the control panel, you can set and control the following functions:
A.-Switching on and off
SUMMER AIR-CONDITIONING : push the “COOL” but-
ton with the ice star.
WINTER HEATING : push the “HEAT” button with the
orange sun.
To switch off, put the switch in the central position.
B.- Setting-regulation of the temperature by means of the
thermostat (TEMP). The thermostat has got a 3 m capillary
with a bulb. The bulb must perceive the sucked up air (it
must not come into contact with the exchanger tongues; it
is in fact the battery where the refrigerant spreads: the
tongues cool down, so that if the bulb comes into contact
with them, it will perceive a temperature value that is lower
than the ambient temperature).
C.- Regulation of the fan speed: by means of the button
with the fan it is possible to regulate the four fan speeds.
Push the button to select the fan speed: upwards arrow
means speed increase and downwards arrow means
speed decrease. Switching on the fan for the first time, it
will run in MED speed. Then it will run according to the last
selected speed.
3.14.A - PLACING
You must choose the correct position to connect the
panel to the board by means of a 3 m cable (includ-
ed) and to install the thermostat bulb on the unit
exchanger. If necessary, you can install the bulb not
directly on the exchanger but in the room, choosing
the right position to control the temperature. To fas-
ten the bulb on the wall, you can use the suitable
plaque.
3.14.B.- INTERCHANGEABLE PLAQUE
The standard plaque (included) is black.
3.14.C - FASTENING
The panel has been designed for a casing fasten-
ing. You must drill into it as indicated on the right.
IMPORTANT NOTE : In the panel there is only low voltage. After having installed it,
the back must not be accessible. An optional protection cover (code: M69330) is avail-
able. If the panel back is accessible because it may suffer damages.
For the technical specifications and for the installation direc-
tions, make reference to the manual VEGA MKII (code:
A52000).

3.INSTALLATION OF THE COMPONENTS
SPLIT QUATTRO air-conditioners are composed by the compressor unit and by the evaporator. SPLIT 4
QUATTRO and SPLIT 8 QUATTRO are pre-charged with R134A and endowed with rapid couplings. The
refrigerant gas circulates between them through pre-charged copper pipes with rapid couplings for the con-
nection. The standard pipe connected to the evaporator is 70 cm long. It is possible to separate two units by
means of extension leads of different lenght. During the connection, observe the directions of labels on two
sides: “Compressor side” and “Evaporator side” according to the following outlet. Handle pipes carefully to
avoid breakages due to incorrect use. The least bending radius is 50 mm.
3.16- PRE-CHARGED GAS PIPES WITH RAPID COUPLINGS (only for SPLIT models)
Except SPLIT 4 QUATTRO and SPLIT 8 QUATTRO
models, all other models of SPLIT QUATTRO range
are not pre-charged.The connection between two
units is a “FLARE” type connection. So only qualified
personnel must carry out the discharge and the
charge of the system.
For the section of outlet and inlet pipes, it is necessary to follow carefully the directions on each SPLIT QUAT-
TRO unit.
3.17 - CONNECTING PIPES
It’s not VECO S.p.a. but the installer to provide the material
for this operation.
The flare must be perfect (without any burr or imperfection).
The lenght of the flare walls must be the same.

4 SEA WATER CIRCUIT
4.1 - SEA WATER ELECTRICAL PUMP
Thanks to the sea water electrical pump the water volume indicated in the exchanger can circulate. The elec-
trical pump must be noiseless. It must work continually and it must be pro-
duced with marine building materials.
4.2 - PLACING
4.2 - A 4.2 - B
4.2 - C 4.2 - D
Install the electrical pump horizontally. Its vertical outlet
opening must be upwards and at least 50 cm below the
water line.
Sea water blade intake towards the bow.
The filter and the connection to the electrical pump must
be linked without any siphon (vertically from the sea water
intake to the electrical pump intake).
The section of the intake pump must be as short as possi-
ble (less than 1 m for an efficient circuit).
4.3 - FASTENING
Fasten the electrical pump by means of the suitable
screws using the holes provided in the base. The
flexible installation (with anti-vibrating system)
makes the electrical pump even more noiseless.

4.4- SEA WATER CIRCUIT
The circuit follows a vertical line from the sea water intake
to the unit exchanger. Then it can follow both a vertical or
an horizontal direction.
Anyway it is better not to create any siphon, because some
air bubbles coming from the sea water intake during the
sailing may remain in the circuit.
The water jet of the discharge must not disturb either the
guests of the boat where it is installed or the ones of the
other boats.

4.5 - ELECTRICAL CONNECTIONS
All electrical pumps are single-phase pumps. So they need
a connection to the neutral wire, to the phase and to the
grounding. Check always that the voltage on the label cor-
responds to the voltage available on board. Execute the
connection according to the diagram on the terminal board
cover. Follow the sequence of the phases for the pump
connection. Check that the rotation direction corresponds
to the instructions of the pump.
4.6 - SELF-PRIMING ELECTRICAL PUMP
If it is not possible to follow the directions at 3.2, it is ne-
cessary to install a self-priming electrical pump following
the same instructions for the connection of a centrifugal
pump. Before starting it, it is necessary to fill the electrical
pump tank to make it self-priming.

AVOID THE RISK OF THE ELECTROCUTION !!!
Only the qualified staff can execute the troubleshooting and the repair.
Keep isolated from the ground during the execution of the electrical operations, wearing dry clothes, rubber
shoes, rubber carpets, etc.... Don’t check wires under voltage if none can bring help.
IMPORTANT NOTE
To avoid possible electrical shocks, that can cause harm or death to people, execute the grounding of the air-
conditioning system, as indicated:
1- Use a suitable electrical cable with ground wire section and isolation to give the charge from the switch on
the control board of the boat to the electrical box of the system. The ground wire must be correctly connect-
ed to the ground terminal of the panel.
2- Check that the ground connection between the electrical box and the air-conditioner hasn’t suffer any da-
mage during the transport.
3- Check that the connection of the water pump to the suitable terminal of the electrical box includes also the
ground connection.
4- Check the ground continuity before switching off the air-conditioner.
