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 100 mm over the top, 100 mm at rear and 70 mm at both sides for proper air circulation is needed.
  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.)
  7. Adjusting the adjustable legs to keep the left/right refrigerator door level,
    • Without adjusting the legs, door height 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.

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.
  3. Connect the refrigerator to an exclusive wall power outlet. The refrigerator can be connected to an outlet soon after it is installed. Surely use with the rated voltage and exclusive power outlet.
  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.

If a door is shut, other doors may open.| –| ● 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.
Does the refrigerator make any abnormal noises (sound)?| –| ●  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.

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.

This is not a malfunction of the refrigerator:

Problem Things to check Instructions
Annoying sound is generated by the refrigerator. ●  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.
Operation sound lasts long.| –| ●  It is because the compressor operates in low-speed for conserving energy
Operation sound sometimes becomes louder.| –| ●  It is because the system changes the operating power of he refrigerator according to the temperature change.

There is something strange with the Vacuum compartment.
