About Non-fluorocarbon refrigerator.
● This refrigerator, including refrigerant and the heat insulator, is using hydrocarbon (non-fluorocarbon). The hydrocarbon is a material that does not rip up
the ozone and have very little influence on global warming. It is the global environment concern material).
● R600a refrigerant is flammable. But the refrigerant is sealed up by the refrigerate circuit, and never leaks by usual use. In case of the refrigerant circuit
being damaged by any chance, please avoid the use of fire and electric product , open the window and ventilate. Afterwards, please contact
Hitachi Service Center.

Troubleshooting
What to do in these situations
This is not a malfunction of the refrigerator.
● The refrigerator is equipped with the dew prevention and heat radiation tubes.
The back and side plates may be heated especially 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).
● A creaking sound comes from the storage compartment. It is the sound caused by friction of the parts due to temperature change.
● It is because the compressor operates in low-speed for conserving energy
.
● It is because the system changes the operating power of the refrigerator according to the temperature change.
● You may feel that the operation sound is larger because the comppressor 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, for long vacations or absences, potentially creating large vibrations.
The surface of the refrigerator
is hot
If a door is shut, other doors
may open.
Does the refrigerator make
any abnormal noise(sound)?
Annoying sound is generated
by the refrigertor.
Operation sound lasts long.
Operation sound sometimes
becomes louder.
