Opening and shutting the door can rise up the temperature. -6~- -6~- Freezer room Do not put any bottle such as beer or beverage because it can be frozen and broken. Cold air absorbing duct Do not place food in front of the duct because it is the entrance of the cold air. Refrigerator door pocket Temperature is high even if the pocket is in the middle. When storing margarine or cheese for one or two weeks, make use of the refrigerator shelf. Crisper Suitable in storing fruits or vegetable. Wrapping can prevent from dryness. ~ ~5 ~5-7~- A ~ ~ B ~ ~ C ~ ~ 5~7 Refrigerating room This model is multi-flow type which flows out cold air from each shelf space. The hot air after making the refrigerator cold, flows into cooling system through the front upper part. Do not put food having much moisture at the middle part of each shelf space ("A", "B" and "C" part). It can be frozen owing to the low temperature. 5
