(2) The priority of quick-freezing mode is higher than that of normalizing frost: during the effective
period of quick-freezing mode, the defrosting is not entered even if the normal defrosting condition
is met; the defrosting entry condition is determined again when the quick-freezing mode is exited;
(3) If the quick-freezing is set during the process of normal defrosting, then the quick freezing shall
start timing when the defrosting is finished;
Note: The quick freezing time is included in the cumulative running time of the compressor.
10.7 Defrosting function
10.7.1Freeze defrosting controlThe accumulative operation time of the compressor reaches 23h,
and the refrigerator does not enter the defrost cycle. If the compressor reaches the shutdown
condition, the refrigerator will stop and enter the defrost process. If the compressor has not reached
the shutdown condition, the compressor will stop and enter the defrosting process for 24 hours.
5. After continuous 3h of compressor operation, it is forcibly stopped for 5min. When the ambient
temperature is lower than or equal to 40 ℃, defrosting shall be performed after two consecutive
forcibly stopping. When the ambient temperature is higher than 40 °C, only two forcibly stopping shall
be performed instead of defrosting after the two forcibly stopping.
6.When the ambient temperature < 15 °C, the cumulative running time of the compressor reaches 6
hours from the last defrosting to the next defrosting. The refrigerator does not enter the defrosting. If
the compressor shutdown condition is met, the refrigerator stops to enter into the defrosting while if
the shutdown condition is not met, the compressor shall enter into defrosting in an accumulation of 7
hours.
7. When the powered comprehensive works for an accumulation of 6 hours, the first defrosting shall
be performed. If the shutdown condition has not been met, the compressor shall enter into defrosting
in an accumulation of 7 hours and the defrosting exit temperature is 12 °C.
Note: If the defrosting sensor detects that the defrosting sensor temperature is lower than 8 °C when the
freezing function is switched to the refrigerating function, it will force a freezing defrosting function, and
the defrosting exit temperature is 8 °C;10.7.2 Refrigerating defrosting control
10.7.2.1 The defrost cycle shall be entered if one of the following conditions are met.The
compressor runs for 6 hours (when the door opening times are more than 20 times and the defrost
cycle is 24 hours).
System running time is 48 hours.
10.7.2.2The process of entering the defrost cycle:
The process of entering the defrost cycle:
The compressor stops and the fan continue to run and enter the defrosting process.
10.7.2.3The defrost cycle shall be exited if one of the following conditions are met
Trv ≥ defrost exit temperature (ie: defrosting sensor temperature ≥ 7 °C).
The defrosting process lasts for 5 hours. Note: the defrosting sensor in the refrigeration fails, and
the defrosting process will automatically exit after 40 minutes.
10.8 Maintenance mode
10.8.1. Enter
Long press the lock/unlock button (D button) + temperature down button (A button) for 3 seconds to
enter the maintenance mode. The display panel displays“0” for units' digit. Press the temperature up
button once to display AP→1→2 →0→AP.If the defrosting sensor fails during defrosting, the
defrosting will exit for 20 minutes;
