8.1

Replacing the Battery

Switch off the freezer as described and pull out the mains power plug to replace the battery. Loosen the
attachment screws of the left side grille on the back of the freezer and remove the grille. Pull the two cables off
the battery, and replace the battery. Connect the new battery with the cables (red cable on red-marked battery
connection). Replace the grille.
8.2 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 freezer ensured?

Are the ventilators operating?
The cooling is switched on again automatically after the compressor has cooled down (approx. one to two hours).
