Warm Temp. LED

Normal Temp. LED Quick feezing LED

Quick freezing SW

Quick Freezing

Pressing the quick freezing switch turns on LED andperforms quick freezing (COMP is operating for 90min continuously.)Pressing the switch again turns off LED and stopsQuick freezing.

Freezer Section Temp. Indicator LED

It checks the temp. In freezer section. If the Temp. Ismore than -5ûC, the warm temperature LED isturned on, and if it is less than -5ûC, the normaltemperature LED is turned on.

1. If press the quick freezing switch, then illuminates quickfreezing LED and starts quick freezing. (If press again, thenstops quick freezing)

2. COMP. and Fan operate for 90 min continuously.

3. After 90 min. F-sensor checks the temperature. If it is COMP.on temperature, it continues quick freezing until it reachesCOMP off temperature.

4. If it becomes auto defrosting time during quick freezing,defrosting starts from Pre-cool after finishing quick freezing.

5. If quick freezing switch is turn on during defrosting Pre-cool,defrosting starts from Pre-cool after finishing quick freezing.But if COMP. has been operating for more than 40 min., thePre-cool will be omitted.

6. If quick freezing switch is turned on during Defrosting Heateron or Fan delay, it performs quick freezing just after finishingdefrosting. But the quick freezing LED comes on immediately.

1. COMP. on/off temperature is controlled by F-sensor.

2. Usually COMP. and the fan operates simultaneously.

1. Restarting in 6 min. after COMP. off.

1. If F-sensor detects temperature over -5ûC, warm temperatureLED is on.

2. During defrosting, the normal temperature LED is always onand F-sensor detects the temperature after finishing defrosting.

3. In quick freezing, warm temperature LED and normaltemperature LED are off.

6. Forced defrost Heater

7. Term COMP.FanHeater

1. After accumulated 13 hours of COMP. operation, it enters todefrosting mode.

2. When power is loaded for the first time or when instant powerfailure occurs, D-sensor detects temperature below 3.5˚C. Itimmediately enters into defrosting mode.

3. During Pre-cool period, it operates COMP. and fan for 40 min.regardless of F-sensor.

4. After finishing Pre-cool, the D-heater is immediately turned on.

5. At D-sensor temperature 13˚C, the D-heater stops.

6. If the D-heater does not stop within 1.5 hours, it enforcedlyturns off D-heater.

7. Fan, COMP. operates in 5 min. unconditionally after finishingdefrosting.

8. The defrosting LED is always on from Pre-cool to fan & COMP.delay.

1. It is set by forced defrosting switch.

2. It can not be set when D-sensor temperature is above 3.5˚C.

3. Manual reset is not possible.

4. If the D-sensor detect 13˚C the D-heater stops.
