4.0 Description of the system
There is a cooling system in the system cabinet which can cool
a liquid to a temperature between 3 and 8°C. The cooled liquid
circulates through the ship in a system of pipes. A thermostat in
the system cabinet regulates the cooling system.
The heat which is removed from the circulating liquid is transferred to the raw water.
One or more so-called fan-coil units are situated in each room.
A fan-coil unit can be regarded as a radiator with a fan; the fan
causes a flow of air past the radiator.
The circulating liquid flows through the radiator in the fan-coil
unit. When the fan is turning the flow of air past the radiator will
be cooled.
The air conditioning system can only function if there is a mains
power supply. The power supply (230 V alternating current)
must be supplied by a generator set or from a mains power
supply from the shore.
One thermostat is fitted in each room. Even if there are more
than one fan-coil units in the room there is still only one thermostat.
The thermostat is used to set the desired temperature for that
room. The temperature in the room is controlled by allowing the
fan(s) to work or not.
A connection to the (battery) ship’s circuit (12 or 24 V) is necessary for the control of the system.

4.1.3 Cooling water circuit
The cooling system condenser is water cooled. The necessary
raw water must be supplied by a separate pump. In order to
protect the water pump from dirt the water must be drawn in
through a through-hull fitting fitted with a water scoop and the
cooling water filter which is supplied. A sea cock must be fitted
onto the water intake (through-hull fitting with water scoop).
After passing through the condenser the water is discharged
outside through another through-hull fitting.

Water pump
The water intake (through hull fitting with water scoop) must be
positioned where a continuous supply of water is guaranteed
under all circumstances. Near the bow, where turbulence can
be created at higher speeds, is a less suitable place. The intake
must also remain under water if the ship rolls. If air is drawn in
instead of water not only is there insufficient cooling but the
water pump can also be damaged by running dry.

Position the through hull fitting in such a way that the sea cock
fitted can be reached easily in order to open or shut it.
The water pump is not self-priming and must be fitted underneath the waterline. The capacity of the water pump depends
on the lift height and decreases as this increases. The maximum
lifting height is 3 m.
Fit the through hull fitting with the grooves pointing forwards.
Use a sealer when fitting the through-hull fitting.
Fit the pump using the brackets supplied and with the OUT connection as shown in the drawing.
Fit the hose columns using a liquid sealer (e.g. Loctite® 577 or
Threebond® 1110B) or using teflon tape.

Hose connections
• Use flexible hoses, diameter 20 mm, for the connections
between the water intake and discharge and the system cabinet.
• Keep the hoses as short as possible and with as few bends
as possible.
See section 4.3, Closed liquid circuit, for notes and details with
reference to the liquid pipes. Connect the liquid pipes to the
hose columns as shown in diagram 5.
4.1.5 Condensation water drain
• Make sure that the hoses do not put any pressure on the
raw water pump housing.
• Only use water and soap, thus no fatty or oily products, to
make fitting the hoses to the hose connections easier.
• Use 2 corrosion resistant steel hose clamps for each hose.
After launching
Check all connections for leakage immediately after launching.
It is not necessary to bleed the system. As soon as the pump
turns it will draw in water and fill the system.
VAC0107
While the cooling installation is in operation condensation will
form in the system cabinet and this condensation water must be
discharged outside.
Use hose with diameter of at least 10 mm for the condensation
drain. The connection for the condensation drain is fitted with
G 1/4” int. Use a hose pillar suitable for the hose diameter used.
Always fit the hose downwards and without sharp bends.

The fan-coil units must be positioned in or nearby the rooms
which are to be cooled.
The fan-coil units should preferably be positioned a small distance above the deck, directly behind a partition in which there
is an air intake grating. If this is not possible then make a duct
from an air intake grating positioned low down to the air intake
side of the fan-coil unit.
The fan-coil units must be positioned with the bottom, the driptray, parallel to the waterline.

The air intake grating must have a net opening of at least 300
cm2.
5
An air filter, size 20 x 20 cm, is fitted on the intake side of the fancoil unit.
Make sure that this air filter is readily accessible since this
makes regular checking of the filter easy. (A dirty filter must be
replaced.)
Therefore it is preferable to use a grating with build-in dimensions of at least 20 x 20 cm.

However, it is preferable to choose an air outlet grating with a
larger net opening. This reduces the speed of the air being discharged and consequently reduces the noise level.
4.2.4 Air outlet
The air outlet grating must be placed as high as possible and
not directly next to an air intake grating.
The air hose must be insulated in order to prevent condensation.

The air outlet opening of the fan-coil unit can be positioned in 3
different ways.
The position of the opening can be altered in the following way:
- Loosen the 4 screws (A) and remove the drip-tray (B).
- Loosen the 4 screws (C), position the fan housing as
required and refit the parts in the reverse order.
VAC0022
4.2.5 Air outlet grating, air hose
While the cooling installation is in operation condensation will
form in the fan-coil unit and this condensation water must be
discharged outside.
The fan-coil unit is provided with 2 G 1/4” internal connections.
Fit both hose pillars (G1/4” x 13 mm) or 1 hose pillar and 1 blind
plug.
VAC0044
Connect the air outlet opening to an air outlet grating using an
insulated air hose with diameter 75 mm.
• If the fan-coil unit is positioned at least 40 cm above the
waterline, a pipe can be led directly to a through-hull fitting,
situated on or above the waterline.
• If the fan-coil unit is positioned under or less than 40 cm
above the waterline, the condensation water must be led to
a lower placed collecting tank. This tank or tray can be automatically emptied by means of a bilge pump connected to a
level switch.
Use hose of diameter 13 mm for the condensation drain.
Always fit the hose downwards and without sharp bends.
The air outlet grating must have a net opening which is at least
as big as the cross-section of the air hose: 44 cm2.

4.2.7 Electrical connections
Check that the voltage, recorded on the type label on the fancoil unit, agrees with the voltage on board (230 V).
Power consumption of the fan is 135 VA at maximum speed.
Speed control
The fan-coil unit is supplied without (fan) speed control. One
speed control, including fitting material, is supplied with each
thermostat, see 4.4.1.
One thermostat is positioned in each room. Fit the speed control into the fan-coil unit (or into one of the units if more than one
fan-coil unit is used).
Loosen the connections block and cut the wires loose. Fit the
speed control using the fitting materials supplied.
Connect the fan-coil unit as shown in diagram 7.
VAC0020
The cable from the thermostat to the speed control must have a
ferrite core, see also 4.4.3 .

4.3 Liquid filled closed circuit
Together with the system cabinet the fan-coil units form a closed
liquid circuit.
Expansion tank
The expansion tank is included in the materials supplied
with the system cabinet.
An expansion tank must be
placed in the return pipe of
the closed liquid circuit. The
expansion tank also functions
as filler tank.
The expansion tank must be
positioned at the highest
point of the complete installation.
When fitting the hoses take account of the following points:
• Keep the connecting pipes as short as possible in order to
limit the resistance in the hoses.
• Fit the hoses in such a way that the risk of external damage
or attack by chemicals or high temperatures is as low as possible.
• Protect hoses that have to pass through partitions with leadthroughs or special couplings.
• Bends must not have kinks, a kink restricts the free flow of
the liquid.
Minimum bend radius: - Hose 16 mm diameter: 130 mm
- Hose 25 mm diameter: 200 mm
• Always fix the pipes with brackets; distance between brackets ca. 50 cm.
VAC0090
Fit the expansion tank against a wall and fit the hose columns.
Cooling liquid pipes
The connections between the system cabinet, the fan-coil units
and the expansion tank must be made with hoses. Use insulated hose for this in order to prevent condensation.
The hose must be suitable for cooling liquids and for temperatures from -25°C to +80°C and a pressure of 2 bar.
Vetus supplies suitable hoses and insulation materials for this.
Hose ø 16 mm, art.code: CCHOSE16.
Hose ø 25 mm, art.code: CCHOSE25.
Insulation tubing for hose CCHOSE16, art.code: CCOVER16.
Insulation tubing for hose CCHOSE25, art.code: CCOVER25.
• Shortening hoses must be done by cutting. Never shorten
these by sawing (sawdust can enter the system and cause
problems) or by pinching (the hose can be too deformed).
• Use good quality hose clamps at every hose connection.
Hoses with internal diameter of 25 mm must be used for the
main supply and return network through the ship.
Hoses with internal diameter of 16 mm must be used for the
main supply to the fan-coil units.
The hose connections on the system cabinet, the expansion
tank and the fan-coil units are the correct sizes for this.
- System cabinet: ø 25 mm
- Expansion tank: ø 25 mm
- Fan-coil units: ø 16 mm
VAC0106
• In order to prevent the formation of condensation between
the hose and the insulation tubing, the ends of the insulation
tubing on the hose should be sealed off with tape.
T-pieces
2 T-pieces 25-16-25 mm are supplied with every fan-coil unit in
order to simplify the fitting.
The last T-pieces are used as reducing pieces, from 25 to
16 mm. Fit the caps supplied on any 25 mm connections on the
T-pieces which are not being used.

When choosing a position for a thermostat take account of the
following points:
• Choose a position where the thermostat is readily accessible
for setting it.
• Fit the thermostat in a position where it is free from draughts.
• The thermostat housing is not completely closed off at the
front and back. A flow of air through the thermostat housing
will influence the operation of the thermostat.

4.5 Taking into service
Filling
Before the system can be taken into service it first has to be
filled with cooling liquid.
The installation is filled at the highest point, the expansion tank.
The installation must be filled with a cooling liquid or with a
water/anti-freeze mixture. See 7.1 Cooling liquid specification.
VAC0092
Never fill the system just with water.
The quantity of liquid required depends on the size of the installation, the number of fan-coil units and the total length of the
piping.
See 7.2 for the quantity of cooling liquid required.
Turn the screw in the bleeder nipple a half or a full turn anticlockwise.
Close the bleeder nipple as soon as cooling liquid begins to
escape.
1 Fill the expansion tank with cooling
liquid. Begin to remove the air from
the fan-coil units when no more liquid
flows out of the expansion tank.
Keep filling the expansion tank while removing air if the liquid
level has dropped.
VAC0093
After all the fan-coil units have had the air removed fill the
expansion tank to about halfway.
There is a switch on the operating panel of the system cabinet
which allows a choice to be made between normal operation
and only operation of the circulation pump and the raw water
pump.
While removing the air keep the liquid
level just under the topmost hose
connection. When the pump is
switched on you can then see
whether the liquid is circulating.
2 Turn the ‘circulation pump’ switch to the left, the LED next to

The cooling system is then switched on and the liquid will be
cooled.
Now check the working of the complete system.
Raw water circuit:
- Check that the sea cock is open.
- Check that the pump is underneath the waterline.
- Disconnect a hose from the pump to the system cabinet in
order to remove the air; the hose should now fill up with
water.
- Check that the pump is running.
Setting the installation
All the necessary settings for the various parts of the installation
have already been carried out.
The button
on the thermostat can be used by the user to
set the speed of the fan of the fan-coil unit.
Cooling liquid circuit:
- There may b e an air bubble in the pump; switch the pump
off and on.
- The pump rotor is jammed because it has not been used for
a long time:
- Switch off the power.
- Remove the cap on the system cabinet which covers the
electrical connections.
- Remove the rubber blanking cap.
- Remove the front plate from the system cabinet.
- Remove the circulation pump cover plug.
- Put a screwdriver in the pump and turn the rotor.
Any air left in the system will leave it via the expansion tank. This
will cause the level in the expansion tank to drop, so that the
tank must be regularly refilled.
When the level of liquid in the expansion tank no longer drops
the system is completely full.
The fan will rotate with a pre-set minimum speed when the thermostat button is set to the lowest position.
min. 95 V AC
VAC0068
This minimum value can be set on the speed control pcb fitted
in the fan-coil unit.
If this setting is altered allowance must be made for the fact that
the minimum voltage on the fan must be at least 95 V alternating current!
Now fill up the expansion tank to above
the topmost connection (ca. 2/3 of the
total height).
VAC0060
After a few weeks check the level in the expansion tank and
refill if necessary.

The water cooled condenser in the system cabinet must be
descaled once a year. Fill the raw water system with cleaning
vinegar (8 %) in order to do this.
5.1 Cleaning raw water filter
Regularly check whether the cooling water filter is dirty.
Clean the cooling water filter as often as is necessary, depending on how dirty the sailing water is, but at least once per half
year. A dirty cooling water filter can cause a higher temperature
than normal or overheating of the cooling installation.

The composition and control of the cooling liquid for an air conditioning installation is of particular importance because corrosion and freezing can cause damage to the system.
Use a ready-mixed cooling liquid (A) or a mixture of a suitable
cooling system protective liquid (antifreeze on ethylene glycol
basis) and tap water (B).
The quantities given below are required to fill the separate parts
of the installation.
A)Ready-mixed cooling liquid
Vetus HCFLUID25 is an example of a very suitable ready-mixed
cooling liquid.
B)Mixture of cooling system protective liquid and tap
water
The concentration of the anti-freeze in the cooling liquid may
not be more or less than that shown below:
Cooling system protection
liquid (Anti-freeze)
Water
Protection against
freezing to
max. 45 vol%
55%
-35°C
40 vol%
60%
-28°C
min. 35 vol%
65%
-22°C
The concentration of the protecting liquid must be maintained
under all circumstances. Therefore if the cooling liquid needs to
be refilled use only the same mixture of anti-freeze and tap
water.
