OPERATING INSTRUCTIONS & INSTALLATION

6-4) Display lamp is directly extinguished right at the stop selection, but it maintains stop condition after the completion of final water supply if water supply, ice extraction or horizontality noise is under progress.

7) At test operation by test key, ice tray operates regardless of F compartment door opening.

This function basically stops the operation if the F compartment door is opened , so that noise may be minimized.

7-1) The ice extraction function promptly stops the operation when the F compartment door is opened while the ice extraction is working where as normal operation is restored when the door is closed.

7-2) During water supply, normal function is performed regardless of the F compartment door opening.

7-3) When checking by opening the F compartment door, if the extraction has been tilted or is not horizontal, it is a stop condition during ice extraction or horizontality operation because of the F compartment door opening. Then check again after more than 30 seconds elapse from the time when the F compartment door closed to ensure a horizontal condition after the water supply operation, if the extraction has not restored its horizontal status, it is ok to judge it to be a trouble/ failure. When operation stops by the F compartment door opening during (ice extraction) operation, because it has been during actual operation, even the test function does not work, but it may work after water supply completion.

=> When checking by opening the F compartment door during ice extraction or horizontality operation, if the tray i tilted or distorted , it is a stop condition because of F compartment door opening. Then check again after more than 30 seconds have elapsed from time when the F compartment door closed, if the tray has not restored its horizontal status, it is ok to judge it to be a trouble/ failure. When operation stops by the F compartment door opening during ice extraction operation, because it has been during actual operation, even the test function does not work.

7-4) During test operation by using the test key, the ice extraction operates regardless of F compartment door opening.

3-9) Defrosting Function

1)Defrosting of the F compartment, Arctic Select Zone, R compartment and the Fresh Select Zone is determined by the cumulated time period of COMP. ON.

2)In case of initial POWER ON of the refrigerator product, defrosting of the Freezer Compartment and Arctic Zone is executed when 4 hrs. of cumulated COMP. ON time period have elapsed.

3)The defrosting period is fixed to 8 hours.

4)Judgment of the defrosting period is determined by the exterior temperature, the number of times the F, R DOOR OPEN, and the duration of the F, R DOOR OPEN period.

5)The defrosting point temperature HEATER ON (start temperature) is determined by the temperature reading of the R defrosting sensor, the F defrosting sensor, the Artic Zone defrosting sensor and the Fresh Zone defrosting sensor as follows:
