The BlueCool S is an air-conditioning system with its four
basic components, i.e. compressor, condenser, evaporator
and throttle element.
Evaporator (air heat exchanger)
Refrigerant vapourises at low pressure and a temperature
below the ambient temperature of the evaporator. It
absorbs heat from the ambient air in the process.
Compressor (refrigerant compressor)
The refrigerant vapour extracted from the evaporator at low
pressure is compressed to a higher pressure, and therefore
to a higher temperature. In the process, additional heat is
fed to the refrigerant.
Condenser (sea-water heat exchanger)
The compressed, heated refrigerant vapour is condensed at
a temperature which is above the sea water temperature. In
the process, the entire heat absorbed in the evaporator and
compressor is given off to the sea water.
Throttle element (capillary tube)
The refrigerant at condensing pressure is expanded to the
evaporation pressure in the throttle element.
NOTE
The heating mode is inefficient if the sea water
temperature drops below approx. 6 °C, as it is
not possible to extract sufficient heat from the
cold sea water. The interior air cannot be heated
sufficiently.
4.6 Dimensions and minimum distances
Cooling mode of operation
The air-conditioning system absorbs heat form the room air
in the evaporator and cools it down by approx. 15°K. The
cooled air is blown into the room with the fan.
The compressor now compresses the refrigerant vapour,
which is then condensed to a liquid when flowing through
a condenser cooled with sea water. The heat released is
emitted to the sea water. The condensed refrigerant is
routed through the throttle element and expanded to wet
steam when flowing into the evaporator. The liquid portion
of the refrigerant is now evaporated and absorbs heat from
the room air again. As a result, the refrigerant circuit is
closed.
NOTE
With all Webasto air-conditioning systems, sea
water flows through the condenser, which is
sucked in via a pump. This ensures the cooling
process. If the sea water temperature is above
35 °C, the cooling capacity of the airconditioning system drops, as the heat absorbed
can not longer be sufficiently transferred.
Heating mode
Heat can also be generated with the BlueCool S airconditioning system. A 4-way reverse valve is installed in the
system for this purpose. As a result, the condenser becomes
an evaporator and vice versa. The sea water heat exchanger
(not the evaporator) withdraws available heat from the sea
water, which is then fed to the refrigerant. The air heat
exchanger becomes the condenser and gives off the
condensation heat to the room air and heats it to approx.
45/50 °C.

5 Installation
5.1 General information 5.2 Installation location
NOTE
To ensure proper operation, the following must
be observed:
• Air outlets must be installed above below
the ceiling to ensure sufficient mixing and
cooling or heating of the room air.
• Avoid a cold air short-circuit between the air
outlet and the air inlet. These must be
mounted with a sufficient distance from
each other.
• The cabin temperature sensor may not be
mounted on the air outlet, as otherwise the
controller cannot detect the actual
temperature in the room.
• All components must be positioned and
installed in accordance with their installation
instructions.
• A noise reduction can be achieved if desired
by insulating the area around the system.
FLAMMABLE
Danger of ignition of explosive gases!
Danger of ship exploding.
Do not install air-conditioning system in rooms
with highly flammable liquids or gases.
CAUTION
The air-conditioning system can intake and
distribute escaping carbon monoxide and
other gases!
Danger of poisoning and suffocation.
Never install the air-conditioning system in the
machine room of the ship's engine or in any
other room in which harmful gases can be
sucked in.
BlueCool S air-conditioning systems are generally installed in
the living area.
Requirements for the installation location:
• Sufficient space must be available to ensure access to
the refrigerant, sea water, condensed-water drain and
electrical connections. See Chapter 4.6, “Dimensions
and minimum distances”.
• The system must be accessible for service and
maintenance purposes.
• The air-conditioning unit must be installed on a flat,
horizontal surface.
• As condensed water results during operation of the airconditioning unit, a drain line must be provided on the
condensate tray.

5.4 Transporting unit
CAUTION
The unit is heavy and can be carried
incorrectly!
Danger of injury, damage to the system and oil
or refrigerant loss caused by dropping and
carrying incorrectly.
Only carry the unit by the condensate tray, by
the fan or by the upper pipe elbows of the
condenser.
Never grasp and carry the unit by other pipes.
See Fig. 7.
The fins of the evaporator bend easily. When
installing, make sure that bent fins are
correctly aligned again to ensure proper air
feed.
5.5 Mounting unit
ATTENTION
Do not remove covers, caps or fittings!
Danger of damage to the electrical components
and refrigerant loss.
Do not remove covers, caps or fittings used to
protect the electrical wiring or to seal off the
refrigerant.
ATTENTION
Water damage can occur!
Danger of water damage to furniture, devices,
etc.
Do not damage the insulation of the conden-
sate tray to avoid condensed-water from
forming on the outside of the condensate
tray.
Lift unit and position it at the installation location.
Fasten the unit using the "L" clamps provided.
Fasten the unit so that secure seating is ensured, however
the unit can be removed again later for maintenance purposes if necessary.
Fig. 7 Transport the unit.
5.6 Installing condensed-water drain line
NOTE
Danger of water damage.
Route the condensed-water drain line with a
downhill slope and without water pockets to
ensure sufficient emptying of the condensate
tray and to prevent damage by backed-up
condensed water.
The condensed-water drain line must match the diameter of
the condensed-water drain fitting on the condensate tray.
The condensed-water drain line must be of a sufficient size
if several air-conditioning units are connected.
Connect the condensate tray to the bilge or other
condensed-water or water-connecting points via the
condensed-water drain line.
No counter-pressure may prevail in the condensed-water
drain line. For example, never connect the condensed-water drain line to the sea water line of the air-conditioning
system.
If necessary, create a new water collection point, complete with a pump, level switch and drain line.
