Installing the cooling unit
• CS-NC15: Observe the drilling template (fig. l, page 11) and the installation
drawing (fig. m, page 12).

Installing 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)
A
NOTICE!
Coolant leakage will lead to system failure. In such cases, the complete
cooling unit must be disassembled, returned, the one-way couplings
replaced and the device refilled at the factory.
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.
