5Intended use
The cooling unit is suited for building your own refrigerator or cooler.
The cooler unit is suitable for cooling and freezing food. The device is also suitable
for use on boats.
CAUTION! Health hazard!
!
Please check if the cooling capacity of the device is suitable for storing
the food or medicine you wish to cool.
6Technical description
The cooling units are suitable for use with 12 V or 24 V DC voltage and can therefore
be used for camping or on boats. Furthermore, you can connect them to a 230 V
mains supply via the rectifiers (see chapter “Accessories” on page 17).
When used on boats, the cooling unit can withstand a constant heeling of 30°.
The cooling unit must be used together with a vaporiser. In addition, you can use an
accumulator with or without TEC control. The CS-NC15 comprises a cooling unit
and a vaporiser.
Use the continuously variable thermostat on the vaporiser to set the desired
temperature.
17
EN
Technical descriptionColdmachine
The accumulator and TEC program control ensure a high cooling capacity
and improve the unit’s efficiency. The accumulator is charged when there is
a sufficient supply of power (for example when powered by a mains adapter). In the
event of accumulator usage or under-voltage, the coolant is drawn from the
accumulator until it is empty. Thus, no power is taken from the battery during this
time.
The TEC program control always ensures that
• Cold energy is stored if there is excess electrical energy (external supply of power
by a generator).
• The coolant accumulator can be used at any time to ensure that the complete
battery power is used for other consumers.
• Stored cold energy is automatically retrieved to preserve the interior cooling
temperature of the cooling area, once the battery capacity is exhausted.
NOTE
I
Further information on the coolant accumulator can be found in chapter
“Use coolant accumulator” on page 27.
6.1Battery monitor
The cooling device is equipped with an electronic device to protect against reversing the polarity when connecting to a battery. To protect the battery, the cooling
device switches off automatically if the voltage is insufficient (see following table).

7.4Installing the external temperature regulator
Mechanical thermostat
The temperature regulator can be mounted either on the outside or inside of the
cooling container. The interior temperature is regulated depending on the surface
temperature of the vaporiser, or for VD-14N and VD-15, depending on the room
temperature.
➤ Connect the coiled end of the sensor cable to the vaporiser (fig. e, page 8, not
VD-14N, VD-15) using the clamping plate. This is premounted on VD-14N,
VD-15.
➤ Make sure that the sensor line does not make contact anywhere else with the
vaporiser or with the suction line.
TEC control
The TEC control must be attached outside of the cooling container. The internal
temperature is regulated according to the vaporiser surface temperature.
The temperature sensor has been factory-mounted to the accumulator.
➤ Connect the temperature sensor with the TEC control via the plug-in coupling.
Mount the one-way couplings (not CS-NC15)
NOTICE!
A
The cooling unit is delivered in a disconnected state (the vaporiser and compressor
are separated); however, it has been filled at the factory with the proper amount of
coolant.
➤ Install the machine part and the vaporiser.
➤ Remove the screwed-on caps from the coupling halves that protect the rubber
seal from dirt.
The fig. f, page 8, shows the condition of the coupling halves after removing the
caps when uncoupled.

9.2Accumulator function
The accumulator function ensures that cold energy is stored automatically (up to
8 hours) if enough electrical power is available, for example when supplied by a
mains adapter.
Stored cooling power is discharged
• automatically when the switch-off voltage is reached (see the table on page 18)
• or manually by pressing the discharge button (fig. 1 A2 or fig. 2 4, page 3).
NOTE
I
The accumulator is automatically charged if,
• the restart voltage is exceeded
• or the accumulator is empty and you switch the device off and on again using the
control button(fig. 2 6, page 3, does only function on VD-06).
