HITACHI R-ZXC740KH Refrigerator Freezer

Product Information: Refrigerator-Freezer

This is a 6-door refrigerator-freezer made in Japan and designed for household use. The model numbers are R-ZXC740KH, R-WXC670KH, R-ZXC740RH, R-ZXC740KS, R-WXC740KH, R-WXC670KS, R-WXC620KS, R-WXC740RH, and R-WXC670RH. The instruction manual contains important information about using the refrigerator properly to ensure efficient cooling and energy savings.

Usage Instructions

Preparation before use
When using the refrigerator for the first time, it may take more than 24 hours to fully cool. Make sure that no food protrudes beyond the storage height limit of each compartment, and allow clearance between each food in each compartment. Otherwise, food and/or package may not be stored in each compartment properly, and the door may not be closed completely. This may cause the refrigerator not to cool sufficiently and/or not to make ice.

Tips for using the refrigerator wisely for energy savings

1. Open or close a door less frequently and quickly. Frequent opening and closing leads to waste of energy.
2. Do not overfill the refrigerator. Overfilling the refrigerator prevents a smooth circulation of cool air, precluding even cooling throughout the refrigerator and consuming unnecessary power. Place food at appropriate intervals.
3. Do not place hot food in the refrigerator. Placing hot food raises the temperature in the refrigerator, which, in turn, raises the temperature of surrounding food.
4. Provide an appropriate gap around the refrigerator. Installing the refrigerator with little clearance between the refrigerator and the surrounding objects prevents the release of heat and thus leads to the waste of power.
5. Replace a damaged door gasket. Cool air leaks through a damaged gasket, which leads to the waste of power. If a name card inserted between the gasket and the refrigerator slides down, the gasket needs replacing.

FAQs

If you face any problems with the refrigerator, you can refer to the FAQs section of the instruction manual. Some common issues that are addressed in this section are:

• If the ice is not made
• If the refrigerator is not cooled down well
• If frost or dew is formed

By following these instructions, you can ensure that your refrigerator-freezer is used properly and efficiently for household use.

When keeping food at lower temperatures (using the “Sensor Cooling” function)

“Sensor Cooling” has two functions:
Lower the temperature of the “Low-temperature Refrigeration Space” (Disabled: About 2 to 6 °C Enabled: About 0 to 3 °C) Suitable for storing prepared daily dishes.
Upon placing a hot food in the “Automatic Rapid Cooling Space” , a sensor detects the temperature of the food and cools it rapidly. Even if you put a hot pan, the refrigerator can cool it rapidly, while reducing the impact on other foods. To put a pan in the “Automatic Rapid Cooling Space” , cool it down to a temperature at which one can touch it with bare hands (50 °C or less). This can prevent burn injury or shelf deformation.
Notice

Low-temperature Refrigeration Space

Automatic Rapid Cooling Space

Enabling “Sensor Cooling” enables both of the “Low-temperature Refrigeration” and “Automatic Rapid Cooling” functions at the same time. Either of the
functions cannot be enabled. When “Sensor Cooling” is enabled, the regrigerator consumes more power than when disabled. The operating sound may be noisier. When “Sensor Cooling” is enabled, temperature in the Double door pockets is also lower than when disabled. When the Refrigerator Compartment is set to “” or “Energy Saving”, the temperature in the entire Refrigerator Compartment is higher than that for
“” by about 1 to 3 °C. If the Refrigerator Compartment is set to “” , the temperature in the entire Refrigerator Compartment is about 0 to 3 °C. In the “Automatic Rapid Cooling” mode, the sensor may not be able to detect the temperature of food, depending on the amount or temperature of the food. However,
when “Sensor Cooling” is enabled, the Low-temperature Refrigeration Space is lower than when disabled, allowing you to cool food more quickly. The above temperature in the “Low-temperature Refrigeration Space” is based on the assumption that the surrounding temperature is about 32 °C and the
temperatures of the Refrigerator and Freezer Compartments are stable at the “” setting.

Closing the door of the Refrigerator Compartment without locking the handle may damage parts or food or form a clearance between the doors, which reduces cooling performance.

Request
If a part of the gasket is stuck together, the vacuum state cannot be maintained. If it is stuck together, please remove it. Since it is difficult to see the left and right sides and the bottom, remove the Vacuum Chilled Case and check it. Pg.42
Dew and/or frost may be formed in the sealed Vacuum Compartment due to moisture contained in food or in the air. Soak a soft cloth in lukewarm water and wipe off the dew and/or frost with the cloth. (Attached dew, frost or ice does not reduce performance.)
If you want to avoid dew, frost or ice, stored food should be wrapped with plastic wrap. Wipe water or soup spilled in the compartment soon, if any. The platinum catalyst needs no replacement. Do not remove it.

Pg.34 The “” setting of the Freezer Compartment consumes more energy than the “” setting by approximately 20%. Changing the temperature setting of the Freezer Compartment also changes the temperature in the Ice Compartment.

Using the Delicious Freezing

The large aluminum tray helps freeze food more quickly.
Just by placing food in the Delicious Freezing Space, the sensor detects its temperature and automatically switches cooling operation.
Wrap a food item with food plastic film or put it in a freezing bag and then place it on the aluminum tray. Dividing a food item into small lumps and flattening them allows the center of each lump to be frozen quickly and facilitates the taking-out of the frozen food.
Notice
Food can be frozen more efficiently if put them in close contact each other on the large aluminum tray without stacking.

Tips for storing vegetables
Types of food recommended to be kept at room temperature
We recommend that the following types of food be kept in a cool location away from direct sunlight: garlic, onion, potatoes, sweet potatoes, squash, and whole (uncut) pumpkins.

Risk of damage due to low temperatures
Some foods might change color or lose flavor if stored in the vegetable compartment for an extended period of time. Other types of food might lose their vitamin C content, grow mold, or spoil.

Vegetables: Eggplants, tomatoes, green beans, sweet potatoes, okra, etc.

Fruits: Bananas, pineapple, mangos, papayas, avocados, lemons, etc.

Request Notice

Above foods become delicious by cooling in the refrigerator for a short time before eating.
If the vegetable compartment contains only a few items, it might not be able to maintain a high level of moisture. In such cases, wrap the items to be stored, in plastic wrap to prevent them from drying out.
The moisture level of the vegetable compartment is relatively high. As such, depending on the amount and types of vegetables stored in the compartment, moisture might condense on the surfaces of containers, on the moisture- retention unit and cover, or on items stored in the compartment. If you are concern about moisture condensing on the surface of foods, wrap foods in plastic wrap before storing them in this compartment.
If the moisture-retention unit is blocked (for example, by food in containers or bags), moisture is more likely to condense. Be sure to store food in a way that does not block the moisture-retention unit.
Water accumulating in the container might cause food to spoil faster. Use a sponge or dishcloth to wipe up any water that accumulates.
Dried food (rice, laver, etc.) stored in the vegetable compartment might absorb moisture. To prevent this, put the dried food in a sealed container or bag before storing it in the vegetable compartment.
The temperature of the space for tall items is slightly higher than that of other containers.

Install a sturdy board with a thickness of 1 cm and then install the refrigerator. Pg.8
Install the refrigerator with clearance around it.
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.
When it is set to “Sensor Cool”/”Quick”, operation sound of the compressor or the fan motor gets louder because of high-speed revolution.
As the compressor operates slowly for energy savings, you may hear an operating noise for a long time.
The operating power varies in response to changes in the inside temperature of the refrigerator, and thus you may sometimes hear a large noise.

These sounds are caused when the refrigerant flows or water flows/ evaporates to remove frost. This is not malfunction.

This sound is heard when the parts squeaks due to changes in temperature in the refrigerator or atmospheric pressure in the Vacuum Compartment. This is not malfunction.

These sounds are caused when the electric parts to control the refrigerator temperature operates. This is not malfunction.
