ARNING
Only technicians authorised by the manufacturer should do repairs or intervene in the refrigeration cycle or
the control of the device.
Improper interventions or repairs can result in considerable bodily injury and/or material damages.
Pull out the mains power plug before performing maintenance or repair work.
7.1 Internal thermal protection
The compressors of the refrigeration unit are equipped with internal thermal protection. This switches off the
compressors and consequently the cooling if there is overheating. As a result, the interior temperature increases
and a temperature alarm follows.
Check the following possible causes:
Is the fin coil heat exchanger soiled?
Is ambient temperature too high?
Is optimal ventilation of the cooling device ensured?
Are the ventilators operating?
The cooling is switched on again automatically after the compressor has cooled down (approx. one to two hours).
You can obtain an overview of the status and error messages in the following table.
You can obtain additional information and help when there are malfunctions and error messages from the
manufacturer.
7.2 Block/unblock setpoint adjustment
The keyboard lock enables blocking the controller keys. When locked it is not possible to change the desired
temperature. Please contact the manufacturer to activate or deactivate the key lock in the parameters.
