Tips
.
When you have frozen a food too hard, leave it at room temperature for about 5 to 15 minutes. it will become easy to cut.
.
If temperature setting of food is switched from freezing to Soft-Freezing, the food should be consumed as
soon as possible (within 1 to 2 weeks).
.
Even if fruits is thawed, it does not return to its original condition. Eat frozen fruit without thawing it.
.
If fruits is stored for more than a week with Soft-Freezing, its taste may change. We recommend eating within 2 to 3 days.
Notice
.
Because food is frozen at about -7℃, it may take about 24 hours for the food to freeze completely.
.
The degree of freezing or freezer burn may vary depending on the food type, cooking method, storage
arrangement (stacking, storage location), the amount of food, and the storage time.
.
Depending on how much sugar, salt, moisture, or fat the food contains, freezing may not be possible or
the food may harden when frozen (cannot be cut immediately with a kitchen knife).
.
Food that has already thawed once is unsuitable for soft freezing. The texture and quality cannot be guaranteed.

Do not store ice in Freezing Case (small / middle / large).
● Freezing cases have some holes on their side wall. If the ice melts due to a power outage,
water may leak from the holes.
Successfully Saving Power
Open and close doors as quickly as possible
If doors are opened frequently or are kept
open for a long time, cold air escapes and
more power is consumed.
Do not cover up air outlets or air inlets
Blocking the flow of cold air can make it difficult
for food in the refrigerator to cool down.
The temperature around the air outlets can drop,
making foods with significant moisture freeze easily.
Don't cram too much food into the fridge
If too much food is crammed into the
refrigerator, the flow of cold air can deteriorate,
making it difficult for food to cool down.
Leave space
Cool hot foods before placing them inside
Placing hot foods in the refrigerator will lower
the temperature, also affecting the freshness
of other foods. (excluding Hot Freezing)

About the ice
●
Ice made with water containing a lot of mineral substances
●
such as mineral water, can cause to ice to form with a white
sediment (white crystals). These are only mineral substances
that have become crystallized. It is harmless.
●
If ice is stored for a long period of time, the
ice cubes may cling together or become smaller.
(This is known as the phenomenon of sublimation.)

Leave space around the refrigerator. When objects or walls
are in contact with the refrigerator, sounds may be heard.
Immediately after beginning use, when the weather is hot,
when the doors are frequently opened and closed, and in
similar situations, the refrigerator switches to high-speed
operation and cools with high power.
This is the sound of the cooling fan motor starting.
This is the creaking sound as warm air enters and
expands the plastic.
This is the sound of the refrigerant (gas) flowing.
This is the sound of the automatic ice maker. Even when
there is no water in the water tank, the automatic ice
maker and pump make a sound about every 100 minutes.
This is the sound of the operation check. The check is
performed even in the “ICE STOP” ice making mode.
Store food so that the door does not make contact with the food
when closed. In the refrigerator compartment, store food on the
shelves and in the drawer doors store food so that it does not
make contact with the ceiling when doors are shut and opened.
Remove any objects. Make sure that the door does not
trap objects such as food, power cords or plastic bags.
Lower the adjustable supports to raise the front side
slightly and make the doors easier to close.
Refer to “When the door alarm sounds” and
“When the alarm cannot be turned off”.
Close the doors so that there are no gaps.
When moisture in the air cools, it forms frost or
condensation. When there is high humidity, condensation
or frost will form even in very small gaps.
Regarding the Vegetable Compartment.
Condensation may form temporarily. Wipe off with
a dry cloth.
Condensation may cause frost to form in the freezer
compartment.
Please minimize the time when doors are kept open.
This is a mark created at the time the plastic is molded.
It is created at the joint where resin flows.
This is not a flaw.

When you hear noise from the lower rear of the refrigerator
Part of the cooling system is the compressor, which operating, does create a more noticeable increase in noise level.
This is normal. However, if the noise is quite loud, this could be because the refrigerator is not installed correctly on
a hard level surface, or there may be a problem that may need service.
CAUTION

temperature and the frequency of door opening, and, if appropriate, a warning that the setting of any temperature
control device might have to be varied to allow for these factors.
2. A rise in temperature of the frozen food during manual defrosting, maintenance or cleaning could shorten the storage life.
