SAFETY AND PRECAUTIONS

1)For starters, be sure to check any chances of the leakage of electricity

2)You could handle a part in the vicinity of electricity after unplugging

3)You should put on rubber glovers to prevent an electric shock on operation test

4)Make sure the rated current, voltage, capacity before using an instrument

5)Keep your wet hands away from the metal goods in the freezer compartment not to be frostbitten

6)Be careful not to let water to permeate the electric part in the machine room

7)with the door open during your working, you might be damaged by that door

8)You should give a tilt to the refrigerator for your safe after removing the breakable goods inside the refrigerator

9)You'd better use cotton gloves if you fix it up around the evaporator

1)Temperature Control of Freezer Compartment

2)Temperature mode changes as the button is pushed.

(Weak) --> Weak --> Middle --> Strong --> Quick FRZ.

3)When Quick FRZ. Mode is selected, FRZ. LEDs flicker 3 times and only FRZ. LED turns ON.

3.Refrigerator Button

1)Temperature Control of Refrigerator (Fresh Food Compartment)

2)Temperature mode changes as the button is pushed.

(Weak) --> Weak --> Middle --> Strong --> Quick REF.

3)When Quick REF. Mode is selected, REF. LEDs flicker 3 times and only REF. LED turns ON.

4.Sleep Button

1)Sleep Mode starts with push of the button and "SLEEP" icon turns ON, while other LEDs are all OFF.

2)If pushed again, the icon turns OFF and returns to normal mode.

3)Automatic OFF ; This mode lasts maximum 12 hours and then ends of itself.

-Sleep ICON LED : OFF

-The rest LEDs return to normal operation.

5. Poor(Weak) Refrigeration Prevention

1)When Poor Refrigeration is sensed, COMP turns ON regardless of F- Sensor.

2)When R-Sensor reaches to R-Fan OFF Point, COMP is controlled by F- Sensor, R-Fan turns OFF.

3)Poor Refrigeration sensing point : R-Sensor OFF Point + 7 °C

4)Poor Refrigeration termination point : same as R-Sensor OFF Point

6. Quick Refrigeration lasts for about 40 minutes.

Diagram of Quick Refrigeration Start during Weak Operation

1)R-Fan and COMP are ON until R-Sensor reaches to Over Refrigeration OFF Point (-7°C).

2)After the reach of the point the mode continues to be Strong until the end of Quick Refrigeration.

3)When Quick Refrigeration (40 minutes) ends, it returns to normal operation.

2) Mode 2

1The mode turns OFF 12hours after the start.

2Overload operation and Defrosting during Sleep mode are same as normal mode.

6.When Sleep mode is terminated, all the electrical parts and C-LEDs return to normal state.

7.If Sleep starts during Pre-Cool, it operates again through the rest after the Sleep.

8.If Sleep starts during Quick Freezing or Quick Refrigeration, previous mode operates for the rest of the time after the Sleep mode.
