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 title 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) When Weak-refrigeration is sensed, COMP is On regardless of F-Sensor.
2) When R-Sensor reaches to R-Fan Off-point, COMP is controlled by F-Sensor and R-Fan becomes Off.
3) Weak-refrigeration point : R-S Off-point + 7
7. If temperature regulation is done during Fuzzy Mode, the mode is finished and temperature regulation is executed.
8. Q.R Mode continues for 40minutes.

1. Fuzzy Mode starts by pressing the button.
2. The mode is finished by pressing the button once again and it returns to previous mode.
3. Application of Predictive refrigeration to Freezer and Refrigerator
1) Checking total time of door-opening by 2hours interval Door-opening is checked as the followings.
Over 30seconds : much opening ( 1 ) Under 30seconds : little opening ( 0 )
Collecting data for 8 days
2) Checking 8 days data
If door-openings over 30 seconds are more than 6 times, it
runs in 3 mode during that time.
If door-openings under 30 seconds are less than 5 times,
it runs in 2 mode during that time.
1. What to be considered in determining defrosting period
1) Total COMP run-time
2) COMP running-rate
3) Total door opened-time
4) Total Time (COMP On + COMP Off)
5) Each Error D-Sensor Error F-Sensor Error RT-Sensor Error Door S/W Error
2. Terms to start Defrosting Period

1) Defrosting mode starts at 6, 8, 10 hours.
2) The mode starts when COMP running-rate is over 80% at
2hours interval.
3) The mode starts when total door opened time is more than
10 minutes.
4) The mode starts when total run-time is more than 60 hours.
5) The mode starts when each Error occurs in case total COMP
run-time is more than 6 hours.
6) The mode starts unconditionally when COMP run-time is more
than 10 hours.
