when starting up or if the door is frequently opened
and closed.
● The two compartments are connected with an air duct.
When closing one of the doors, the other door may be
opened by the air pressure through the duct.
This is a normal phenomenon.
● The sound like water flowing and boiling water is the
sound of the cooling liquid (refrigerant).
● A creaking sound comes from the storage
compartment. It is the sound caused b y friction of
the parts due to temperature change.
● Slight waving and/or distortions are generated in the
manufacturing process of the refrigerator.
They may be conspicuous according to the position of the
light source and/or the brightness etc.,
but there is no problem with the performance.
Instructions
● You may feel that the operation sound is loud because the
compressor operates in high-speed under the
following conditions: the refrigerator does not cool fully
on the occasion such as using it for the first time,
opening/closing the door frequently, the surrounding
temperature is high.
The sound becomes more quiet after cooling fully.
The compressor operates at low speed at night, or during
long vacations or absence.
●
It is because the compressor operates in low-speed for
conserving energy
It is because the system changes the operating power of
●
he refrigerator according to the temperature change.
