OPERATING INSTRUCTIONS & INSTALLATION

3-17) Operation Condition Recovery Function in Case of Power Outage

1)In case of momentary electricity interruption, customer's NON-SENSE CALL would arise if PANEL DISPLAY is initialized. To prevent this, initialization or recovery(of previous operation status) is operated by way of judging the temperature in the freezer compartment.

2)If the temperature in the freezer compartment is judged to be below 41°F at initial POWER ON, it is judged to be a momentary electricity interruption during operation, and functions(power freezing, power refrigeration, setting of the freezer compartment, setting of the refrigerator, setting of Arctic Select Zone, setting of Fresh Select Zone, ice type, lock condition, etc.) related to PANEL DISPLAY are restored.

3)If the temperature in freezer compartment is judged to be above 41°F at initial POWER ON, it is judged to be a long- term electricity interruption, and PANEL DISPLAY is initialized. (Automatic settings: freezer compartment at -2°F , refrigerator compartment at 38°F , Arctic Select Zone to freeze, and Fresh Select Zone to cool)

3-18) Option Setting Function

Changing to Optional Mode

If the Arctic Select Zone Setting Key + Refrigerator Compartment Key is simultaneously pressed for about 12 seconds under normal operating condition, display is converted to an option setting mode.
