•No change of setting temperature occured during quick freeze and refrigeration selected.
•Temperature of freezer and refrigerator can be re-setted while quick freeze and refrigeration operates.
1)Quick freeze
(1)Comp. and F-fan runs continuously for two and a half hours when quick freeze selected. ( one minute after selection )
(2)During quick freezing the refrigerator controlled by setted notch.
2)Quick refrigeration
(1)Comp. and R-fan runs until the temperature of refrigerator reaches -4˚C when quick refrigeration selected.
(2)After the temperature reaches -4˚C the ’HIGH’ notch runs for an hour and finish quick refrigeration.
(3)Unless the temperature of refrigerator reaches -4˚C within two and a half hours quick refrigeration stopped.
3)When quick freeze and refrigeration selected at the same time
(1)Each function applied at the same time. Quick freeze runs Comp. and F-fan for two and a half hours and quick refrigeration runs Comp. and R-fan for two and a half hours with no relation of each other.

2)After that defrosting cycle can be varied from 6 hours to 32hours. (Comp on time)
7-9 Testing
•Testing is for PCB, product, function and service.
•After testing, turn the power on to start self diagnosis.
1)Forced operating
(1)As the button on PCB pushed once, Comp starts immediately without 5 minutes delay.
(2)If forced operating selected the notch of freezer and refrigerator fixed to ”HIGH” and ”MIDHIGH”. Then Comp and F-fan is controlled to pull-down and R-fan is controlled to ”MID-HIGH” notch.
(3)Pull-down maintained just for 24 hours during forced operating, after that automatically defrost freezer and refrigerator and then starts normal operating.
(4)Turn the power off or select test cancel mode to cancel the forced operating.

(3)Forced operating cancelled automatically by starting foced defrosting and return to normal operating after completion of defrosting.
3)Test cancel mode
(1)One more push in the status of forced defrosting of F/R will run normal operating.
(2)Alarming stopped in the test cancel mode.
7-10 Self diagnosis
1)Self diagnosis at first power on
(1)As the power applied to the refrigerator first time, all displays show and run the self diagnosis.
