Preparations before Use

Installation

1. Install on a rigid and level floor.

2. Please use this refrigerator between the room temperature of 10°C to 43°C Sufficient performance may not be obtained, if room temperature is too low or too high.

3. Do not install where the refrigerator is exposed to direct sunlight or other heat source.

4. Install in an atmosphere which is dry or has air ventilation.

5. The refrigerator requires enough air ventilation space around the cabinet to have efficient cooling performance Space of at least 30 cm over the top, 10 cm at rear and 5 cm at both sides for proper air circulation.

6. Ground the refrigerator to prevent electric shock and noise interference. Always ground this refrigerator when using it in place with high humidity or moisture.
   (Please consult with retailers or Hitachi Service Center.)
   ■ Without adjusting the legs, door heigh may not be level, or there may be abnormal vibration or noises depending on floor conditions. Follow the instructions below.
   ■ Turn the adjustable legs until they touch the floor firmly.

7. When opening the doors, please open carefully until it stop approximate at 130° Do not over open. Otherwise the door may cause damage.

8. Make the refrigerator stand horizontally by adjusting the leveling legs (adjustor).

Beginning

1. After transporting : If Refrigerator has been kept horizontal position for more than 10 minutes for transportation or any other reasons, it should stand upright for more than 1 hour before plugging it in.
2. Cleaning inside the refrigerator. Wipe the surface gently with soft cloth. can be connected to an outlet soon after it is installed. Surely use with the rated voltage and exclusive power outlet.
3. Connect the refrigerator to an exclusive wall power outlet. The refrigerator
4. The compressor will start running in approximately 30 seconds, if inside is not cold.
5. Allow enough duration for sufficient cooling before storing food. It may take about 4 hours to fully cool down and could even take about 24 hours when the ambient temperature is high.
6. Opening the door for long periods can cause a significant increase of the temperature in the compartments of the appliance.

Food storage

1. Keep enough space between food. Several food placed too close together may obstruct the flow of cold air.
2. Make food cool enough before putting it in the refrigerator. Putting warm food in the refrigerator raises the inside temperature and wastes electricity.
3. Do not block the cold air vent. This will adversely affect the cold air flow and may not keep the temperature inside even. Moreover, it could result in food near the vent freezing.
4. Using plastic wrap or sealed containers prevent the food from drying or transition of smells.
5. Store raw meat and fish in suitable containers in the refrigerator, so that it is not in contact with or drip onto other food.

Troubleshooting

Before you call for service, please check the following items:

properly?
● Check the fuse box for blown fuse or tripped circuit breaker.
The refrigerator does not get cold enough.| ● Is the refrigerator placed in the direct sunlight?
● Is the refrigerator placed near heat source?
● Is the temperature set to “Cold”?
● Has anything not been placed in the refrigerator?
● Is the food stored too much?
● Is the door opened and closed too frequently?
● Is the door being slightly open?
Food in the refrigerator compartment freezes.| ● Is the temperature set to “Coldest”?
● Do you place the high moisture food or vegetables at the inner part of the shelf nearby the cold air vent?
They will be frozen if being placed nearby the cold air vent.
Dew appears Outside| ● When the ambient humidity is too high, the door gasket may have dew. Please wipe it up with dry cloth.
Dew appears Inside| Please wipe it off with dry cloth and please check the details below.
● Is the door closed firmly?
● Is the door opened and closed too frequently or opened for a long time?

prevention and heat radiation pipes.
Especially the back&side may be heated when starting up or it the door is frequently opened and closed.
If a door is shut, other doors may open.| ● The air duct of two compartments are connected. When closing one of the doors, the other door may be opened
by the air pressure through the duct. This is a normal phenomenon.
Does it have any abnormal sound?| ● The sound like water flowing and boiling water are 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.

Service Center
