9.10 Defrosting function
1. Defrost the freezing chamber as per the accumulative operation time of the Compressor
2. If power failure occurs abruptly to the Compressor and the defrosting sensor in freezing chamber is less
than 0
o
C after powering on, then first conduct defrosting once. If more than 0
o
C, then defrosting is not
needed.
After that, conduct defrosting according to using condition and ambient temperature in a period between 6
and 24 hours as per the accumulative operation time of the Compressor.
