9.7 Defrosting function
1.Defrost the freezing chamber as per the accumulative operation time of the Compressor2.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.
