Defrosting occurs during compressor standstill periods. The controller has an automatic
defrosting function. The compressor will be stopped for 20 minutes at every 4 hours of
compressor running time. After the 20 minutes has elapsed, the controller measures the
cabinet temperature every 2 seconds, and if the temperature exceeds 6°C the compressor
starts again. If the temperature stays below 6°C, the defrosting continues for 45 minutes.
The defrost water is collected in the channel under the evaporator from where it is led
through a tube down into the re-evaporation pan over the compressor.
