DEFROST
Defrost in refrigerator
The following 2 types of defrosting methods are provided for the refrigerator. Both of them are
controlled automatically.
Cycle defrosting
The refrigerator 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 refrigerator 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 refrigerator. In
this case, the defrosting operation is started automatically when the defrost sensor detects the frost.
During the defrosting, the current refrigerator temperature and dF is displayed alternately when the
indicator for refrigerator temperature is lit.
After completion of defrosting, dF display is disappeared and the refrigerator returns to the normal
operation.
<Important> During the defrosting, the refrigerator temperature reaches around 10
o
C temporary.
Defrost in freezer
The freezer has no automatic defrosting system. Stop the freezer operation and remove the frost
when the frost is accumulated in the freezer.
Following shows the procedure for defrosting.
1.
Move all storage items in the freezer to other freezer.
2.
Stop the freezer operation according to the procedure on page 23.
The current freezer temperature and OFF is displayed alternately when the indicator for freezer temperature is
lit. (Only the current refrigerator temperature is displayed when the indicator for refrigerator temperature is lit.
OFF is not displayed.)
3.
After the frost in the freezer is melted, remove
the drain hose cap to take out the drain hose.
Set a pan under the drain hose. Remove the
drain hose cap and drain port cap in the freezer
to drain the water.
4.
Wipe off the freezer with a dry cloth. Replace the caps to the drain hose and store the drain hose.
Then replace the cap to the drain port in the freezer.
5.
Start the freezer operation according to the procedure on page 24.
6.
Check that the freezer temperature reaches the set temperature and replace the storage items.
