Explanation and action
When moisture in the air cools, it forms frost or
condensation. Even when a door is open only slightly,
it can cause frost or condensation, or dripping onto
the fl oor.
Condensation may form temporarily. Wipe off with a dry
cloth. Condensation may cause frost to form in Freezer
compartment. Please minimize the time that doors are
kept open.
Install the refrigerator away from electronic devices
such as televisions.
We recommend using a separate power supply. When
there is no grounded terminal on the plug, connect the
grounding wire.
Immediately after installation, when the weather is hot, when
the doors are frequently opened and closed, during the fast
cooling operation, and in similar situations, the refrigerator
switches to high-speed operation and cools with high power.
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 automatic ice maker's
operation check.
The check is performed even in the "STOP" ice
making mode.
This is the sound of the fan motor starting.
This is the sound of the refrigerant (gas) fl owing.
This is the creaking sound as warm air enters and
expands the plastic.
This is the operating sound of the damper as it adjusts
the air fl ow.
This is the sound of air blowing through the cooling fan.
