DEFROSTING
The following 2 types of defrosting methods is provided for the refrigerator. Both of them are controlled
automatically.
●
Cycle defrosting
The chamber temperature is kept stable by ON/OFF operation of the compressor. When the
compressor is OFF (stopped), the frost on the evaporator is melted by the heater. This defrosting never
influences to the chamber temperature.
●
Defrosting by defrost sensor
The cycle defrosting may not be sufficient to remove the frost on the evaporator when the ambient
temperature is high, the door is opened frequently, or heavy moist items are stored in the chamber. In
this case, the defrosting operation is started automatically when the defrost sensor detects the frost.
During the defrosting, the current chamber temperature and dF is displayed alternately on the
temperature display.
After completion of defrosting, dF display is disappeared and normal operation resumes.
<Important>
■ During the defrosting, the chamber temperature reaches around 10 o C temporary.
■ Too much frost is accumulated on the evaporator when the chamber is running under high temperature
and humidity condition. For example, the unit starts to defrost once a week with 2
o
C setting in the
ambient of 30
o
C and 80%R.H.
