Freezer door pocket
Do not put ice cream or frozen
food in freezer door pocket to
store for a long term. Opening
and shutting the door can rise up
the temperature.
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.
Freezer room
Do not put any bottle such as
beer or beverage because it can
be frozen and broken.
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.
