Installing the cooling unit
TEC control
The TEC control must be attached outside of the cooling container. The internal
temperature is regulated according to the evaporator 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!
Only persons who are skilled and knowledgeable in the field of refriger-
ation technology may connect one-way couplings. The general regula-
tions for handling refrigerants must be observed!
The one-way couplings are only suitable for connecting the refrigeration
units once. Re-opening or improper connection of the couplings will
result in a complete loss of the refrigerant and in the failure of the refrig-
eration unit!
In such cases, the two previously connected parts of the cooling unit
must be disassembled and send in. At the factory, the one-way cou-
plings are renewed and the product is refilled with refrigerant.
The two components of the refrigeration unit – the evaporator and the compressor-
condenser unit – are supplied separately. The components are connected with one-
way couplings. The refrigerant quantity required to operate the entire refrigeration
unit is already contained in the two components. A subsequent filling with refrigerant
is, therefore, not necessary.
➤ Assemble the compressor-condenser unit and the evaporator unit.
➤ Remove the protective caps and plugs from the unconnected halves of the one-
way coupling of the compressor-condenser unit and the evaporator unit.
➤ Carefully clean the coupling seat and the threaded surface to prevent dirt or for-
eign material from entering the system.
A
NOTICE! Risk of coolant leakage
• Always use two wrenches when tightening the one-way couplings to
prevent the pipes from twisting!
• Reusing the one-way couplings is not permitted!
• Determine which of the two one-way clutch connections is more dif-
ficult to access with the wrench and connect it first.
• Always connect only one one-way coupling connection and then the
second.
