OPERATING INSTRUCTIONS & INSTALLATION

3-1) Digital Panel

Freezer

Fridge

Arctic Select Zone

Fresh Select Zone (CR)

3-2) Temperature Control Operation

1)Temperature Selection for the Freezer Compartment

1-1) There are automatic temperature asettings of -2 for the freezer compartment and 38 for the fridge compartment

when initially applying electric power after installing refrigerator.

The numbers on the display represent the inside temperature of the refrigerator product. when the set temperature and the displayed temperature are diffrent from each other, it will be automatically adjusted to the

set temperature. (actual display range of temperature : 15	~ 80 for the fridge compartment and –25 ~80
for the freezer compartment)
when the freezer temperature is set, it will display the set temperature for the first 5 seconds. and then, it will
display its current temperature.
1-2) The temperature of the freezer compartment may be set to 6	~ –14 by operating the temperature selection
button for the freezer compartment.

2) Temperature Selection for the Refrigerator Compartment

2-1) The temperature of the refrigerator compartment may be set to 46 ~ 34 by operation the temperature selection button for the refrigerator compartment.

(Example:

	38	36	34	Power Cool 46	44 …. 38 )

2-2) Temperature that has been set for the freezer compartment/ the refrigerator compartment may vary by a little difference depending on ambient temperature and user’s food storage style. (Take heed because if food would contact too closely with refrigerator temperature sensor position, then under cooling overcooling may arise as

Note) If temperature in the freezer compartment is lower than 41 (when electric power is supplied again after momentary electricity interruption / when electric power had been cut off for a short time by unstable electric supply because of electricity supply line problem so as to be connected again, then the refrigerator judges it as momentary power interruption. So the refrigerator reads again to use them after saving the temperatures and the functions that had been set in EEPROM
