The refrigerator is equipped with the dew pre

vention and heat radiation tubes. 

The back and side plates may be heated es

pecially 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 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).

There are waving and/or distortions

on the door surface, the side and

the top surface of the refrigerator.

●

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. 

● A

 creaking sound comes from the storage compartment. It is the 

sound caused by friction of the parts due to temperature change

.

Return all parts to their original locations.

When replacing lamp (LED) is required. Please contact your dealer or Hitachi Service Center.

Warning

Do not splash water into the doors and refrigerator body.

It may cause electric shock or fire.

It may cause refrigerant leakage because of pipe rust.
