Defrosting
Normal defrosting takes place automatically 4 times per day. If the product is under an extremely
intense load (frequent openings of the door and frequent replacement of the goods), it may
become necessary to perform manual defrosting.
Starting manual defrosting: Press the button for more than 4 seconds.
The symbol will be lit while defrosting is occurring. After defrosting has been concluded, the
symbol will flash to indicate a drip time. Immediately after the drip time has been completed,
the cabinet's refrigeration system will start up again.
If pressing the button as described above does not result in defrosting being performed, then
the reason is:
 that the evaporator is ice-free, which means that defrosting is not necessary.
 that the defrosting is delayed, due to the compressor is running. This is indicated by is
flashing.
Shortly after defrosting has been completed, the compressor starts, and the symbol is lit to
indicate that the refrigeration process is working once again.

Do not use sharp or pointed objects to accelerate the defrosting process.
