3 COMPONENTS INSTALLATION
3.1 - FUNCTIONING OF THE AIR-CONDITIONERS
During the cooling cycle, the refrigerant circuit transfer the heat from the
ambient air to the sea water.
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 detailed information about the control panel, please refer directly to the
remote control panel manual.
While choosing the unit position, it's important to consider the following elements:
1 - the accessibility to the air filter for cleaning operations
2 - the necessary space to fast of the provided clamps
3 - the connection for the condensation drainpipes
4 - there are two possible orientations of the air discharge. Choose the best for connecting the air ducts
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
Place the pipe-tightening clamps of the water system so that once the unit is arranged, it is still possible to tight the screws.
We suggest to use all stainless steel components.

3.3 - PLACING
A.- The unit has been designed to
take the ambient air directly away,
therefore it must be installed in the
room that has to be conditioned.
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.

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 also be in a
different position (see the picture 3.6).
The second solution (picture 3.8) is the best one thanks
to the best sound isolation of the system.
The important thing for the air is to find the shortest and
most linear path, still leaving some space for the filter
maintenance (A).

D. The air-conditioner is connected to the electrical box
through cables of 2 m lenght. So there must
be an accessible space (next to the compressor unit
for SPLIT models) to install the electrical box.
E. The thermostat bulb and the aspiration filter must
be mounted on the air-refrigerating gas exchanger.
This side must be accessible for the filter maintenance.
F.- 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 using special latches.
The bulb must kept separated from the air exchanger
because it must be influenced only by the sucked up
air, but not by the refrigerating circuit. It's also possible
to install the bulb in the room instead of placing it on the
air exchanger, so that it is more sensitive to the ambient
temperature. To fasten the bulb to the wall, you
can use a special plaque given.

The fixing has to be done using the
clamps given with the fancoil.
It's suggested to use anti-vibrant when
the installation is in a cabin.
It's also important not to push hard on
the connection cable of the electrical box.
Fancoil FC model has to be fixed on the ground.
EVA fancoils are arranged to have anti-vibrations installed, using apposite
components that can be screwed to the stainless steel basin (see picture 3-13).

3.8 - CONDENSATION OUTLET
The air-conditioning determines the generation
of the condensation water due to the humidity
of the conditioned air. This condensation water
must be discharged 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 rubberholders
of 19 mm on the condensation
collection basin.
Each unit is endowed with two condensate
water outlets, as you can see in the picture
above.
If for any reason the condensation discharge pipe has
to be long, it is better to use the special “L” connection.
Installation as in the picture 3.23 must be avoided. In this
situation 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, since it can suck up unpleasant
smells due to the exhaust emissions of its own or of other engines.
Please refer to the safety regulations of the different countries.

While the air-conditioner is working, it sucks up and
causes a light vacuum in the room. The condensation
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 3.26 to stop the air.
To check the actual efficiency
of the condensation outlet, pour

The air-conditioner sucks up the ambient air through an
air-refrigerating gas exchanger endowed with many
aluminum tongues. These tongues 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 picture 3.28).
The filter must be easily taken off to clean or replace it.
For taking off instruction, please follow the picture related
to your model.

3.9- AIR CIRCULATION SYSTEM
3.9.A - ASPIRATION
The ambient air is sucked up through one or more grills of suitable dimensions. The minimum dimensions are 350 X 292
(To canalize the air flow back, call a technical assistance).
3.9.B - AIR CIRCULATION
3.9.C - AIR DUCTS
The efficiency of the system depends on the air volume.
This is why 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.

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.

In order to measure inlet air, please follow the below steps:
1.- Measure air inlet grill, excluding the frame, to get the net surface in m
2
;
2.- Measure air flow speed in different positions of the grill;
3.- Sum together all the different measured speeds and divide them by the number of measurements to get the mean speed
(measurement can be in m/s or in other formats, depending on the instrument)
4.- If necessary, convert the mean speed in m/s, and appy the following formula to get the air flow of your system:
Q = SxVx3600
Q = m3/h of air that can be conditioned by your system
S = grill surface in m2 (excluding the frame)
V = air speed in m/s
The air flow value in m3/h obtained with the previous formula has to be compared with the technical specification provided for the product.
Air flow values that vary more that 15/20% are not considered acceptable.
It is also suggested to measure the outlet grills' air flow in order to compare the measurements with the inlet grill one.
When you need air conditioning for two or more spaces, it is important to calculate the air flow to input in the area. This value can be
calculated only knowing the amount of sensible heat of each single space.
If this information is not available, we suggest the following.
Divide the air flow value obtained before (Q) by the total m3 of the space to be air-conditioned. This will give you a ratio between the air
flow that your system can handle and the volume of the air-conditioned space. Multiply this ratio by the volumes of each single area to get
the air-conditioned flow value.
Example:
6 AIR INLET MEASUREMENT
7 USAGE INSTRUCTIONS
7.1 – FAULT DETECTION
Fault detection must be always carried out by qualified technician and by following safety rules.
7.2 - MAINTENANCE
To get the best performances from your air conditioning system, it is important to do the suggested maintenance described below. Periods
can vary based on the installation area of the boat, based on pollution and based on the system usage.
●
Clean the air filter monthly
●
Clean the condensate drain pipe every 4 months
●
Clean the condensate pan every year
●
Substitute the remote control battery every year (only for model VEGA MK2)
Following tasks must be executed with the system off and only by authorized technicians. Do not check eletrical wires if there nobody else
with you, who can assist you in case of emergency. Check sea water piping and fresh water piping every year. Please refer also to the
system Installation Manual.
7.3 - CONDENSATE WATER AND DRAINS
While working, fancoils produce condensate drain, especially when humidity is high. It has to be checked periodically that there are no
leaks on the condensate water drains and that the condensate water drains regularly. For this checks, put some water in the condensate
drain and check that it gets drained quickly.
If the condensate water is drained in the bilge, it is advised to drain it in a specific separate area, since it can generate bad smells.
7.4 - AIR FILTER
The system requires to clean and periodically change the air filter before heat exchanger (B). This filter is required to clean the air before
it goes into the heat exchanger of the fan coil.
There is no specific rule for the system maintenance; it depends on the running hours of the system and from the air pollution. We advise
to clean the air filter every 30 days maximum.
If the air filter is not completely clean system can stop working or loose efficiency. In cool mode (CO) the system efficiency can decrease
significantly, while in the recerce cycle mode (RC), it can cause an high pressure lock and the system will stop working. In the electrical
heater models (EH) the system will stop working due to a security sensor,
7.5 - LOW TEMPERATURE EXPOSURE
If the boat faces sub-zero temperatures, it is required to empty the fan coil and the piping system from all the residual water. In order to
do this, please follow the instructions on the CWS system usage and maintenance.
