R-G420KH Series 305L Multi-door Refrigerator

Product Information

This is the instruction manual for the Refrigerator-Freezer
model R-G420KH and R-G420KHL. It is designed for household use and
is made in Japan. The refrigerator has 5 doors and both the R- and
L-hinge models are identical, except for the location of the door
hinges. It is important to note that it may take some time to cool
the refrigerator for the first time, possibly more than 24 hours.
The manual also emphasizes the importance of ensuring that no food
protrudes beyond the storage height limit of each compartment and
that there is clearance between each food item to ensure proper
storage and complete door closure. Failure to do so may result in
insufficient cooling and ice-making.

Product Usage Instructions

Here are some tips for using the refrigerator wisely for energy
savings:

1. Open or close a door less frequently and quickly. Frequent
   opening and closing can waste energy.

2. Do not overfill the refrigerator. Overfilling prevents proper
   circulation of cool air, leading to uneven cooling and unnecessary
   power consumption. Place food at appropriate intervals.

3. Avoid placing hot food in the refrigerator. This raises the
   temperature inside, affecting the surrounding food.

4. Provide an appropriate gap around the refrigerator. Installing
   it with little clearance between the refrigerator and surrounding
   objects prevents heat release and wastes power.

5. Replace a damaged door gasket. Cool air can leak through a
   damaged gasket, resulting in energy waste. If a name card inserted
   between the gasket and the refrigerator easily slides down, it
   indicates that the gasket needs replacing.

The manual also includes answers to frequently asked questions
(FAQs) regarding issues such as ice not being made, insufficient
cooling, and the formation of frost or dew. For specific
instructions related to these issues, please refer to the manual
pages mentioned next to each question.

It takes time to cool for the first time. Pg.40, 41
It may take more than 4 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. Pg.50, 52
Otherwise, food and/or package may not be stored in each compartment properly, and as a result, the door may not be closed completely. It 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.

It may take more than 4 hours to cool well the inside of the refrigerator, depending on conditions such as the ambient temperature or storage state of foods. It may take 24 hours or more in summer, etc. Do not put ice cream, uncooled foods or perishable foods in it until the inside of the refrigerator is cooled well.
Perform “Ice Maker Cleaning” when using the automatic ice making function first. Pg.57 A series of ice making operation will start automatically after the inside of the refrigerator is cooled well.
(When using for the first time, it may take 24 hours and more to make ice.) If the inside of the refrigerator has a low temperature, cooling may not start until the elapse of about 10 minutes after inserting the
power plug.

Notice Pipes may require rust preventive measures.

If your refrigerator is installed near a hot-spring or industrial area or a sewage pipe, the refrigerator pipe may corrode due to

sulfidizing gas. Consult your dealer. If the pipe is blackened, any failure due to a gas hazard is not covered by our guarantee.

You will hear an operating sound after inserting the power plug. You may feel that the compressor or fan is noisy before

the refrigerator is fully cooled.

Do not peel off the seal on the back or plastics at the lower part of the side.

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: Tomatoes, green pepper, cucumber, eggplants, green beans, sweet potatoes, okra, etc.

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

Request
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.

Notice
52 The temperature of the space for tall items is slightly higher than that of other containers.

Sound like something is caught (clacking) Sound like roaring (honking) Sound caused immediately after closing the door (booming)
Sounds caused by the Automatic ice maker (zooming) (rattling) (clunking)
Sound is heard sometimes (clacking)

Action and Reasons
Install a sturdy board with a thickness of 1 cm and then install the refrigerator. Pg.40
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 “Quick Freeze”/”Quick 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.

These sounds are made when ice is separated from the ice tray of the

auto ice maker or water is supplied to the ice tray.

This is not malfunction.

To stop the sound, touch the

Is the Vacuum Compartment set to “-1°C (Subzero)” or “Off (Vacuum off)” (Non- vacuum)?

Set the “+1°C (Chiller)”. Pg.47

Plastic smells

—–

This smell occurs because a lot of plastic parts are used in the refrigerator, but the smell decreases gradually while cooling. This is not malfunction.

Ice smells

Do the water supply container and/or water filter become dirty? Or does ice become old?

Wash them regularly to prevent “slime” and/or “fur”.

Pg.59

—–

Chlorine may strongly smell because chlorine in tap water is condensed.

It smells in the refrigerator Is any food which strongly smells stored without any wrapping?

The deodorizing function cannot completely remove all smells. Seal that kind of food with plastic film etc.

Dew condensation occurs in the Vegetable Compartment.

Did you place a large amount of vegetable containing much water? Is the Moisture Unit blocked with food bags or containers?

As the Vegetable Compartment is more humid than the other compartments, dew may be found in the case or ceiling of the Vegetable Compartment or on the surface of food, depending on the amount or type of vegetable stored there. This is not abnormal state. To avoid condensation, wrap a vegetable with plastic food wrap before storing it in the Vegetable Compartment. Heavy condensation may cause water to be pooled in the Vegetable Compartment. Wipe it off with a soft cloth.
A blocked Moisture Unit is likely to cause condensation. Move the food bags or containers that block the Moisture Unit to other portions. Wipe off the dew with a soft cloth.

When a fruit fly, etc. enters the refrigerator

Are there fruit flies around it?
Is there any food with strong smell in the refrigerator? Is the door left open for a long time?

Action and Reasons
The refrigerator may be charged with static electricity, but there is no problem with the safety.
It is caused by the electromagnetic radiation slightly generated from this refrigerator. Install the refrigerator away from the television, radio and interphone. It is recommended to connect the power plug to the power outlet separated from the antenna terminal. Those lines are caused by the liquid resin flowing when plastic is molded. They are especially conspicuous for the transparent parts, but there is no problem with the strength and they can never lead to any cracks. 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., which is not malfunction. There is no problem with the performance. This hole is used to escape the air inside when filling the heat insulation material into the door during the production process. It is neither a flaw nor abnormal thing.
Hole (on a side of Refrigerator Compartment)
Hole (inside of the door)

• Some products have an adhesive seal to conceal the hole. Please do not peel it off. Reduce the number of times of opening and closing the door and avoid storing food additionally until the electric supply is restored. Please check each setting on the panel for operation after the power comes back on. Remove all the items in the refrigerator. Unplug the refrigerator to take care of the inside or the automatic ice maker. Pg.56-59 Leave all the doors open to dry the refrigerator for 2 or 3 days. Any operation to remove frost is not required because this refrigerator remove frost automatically. Thawed water is collected in the evaporating tray and automatically evaporates. See “Transporting your refrigerator (transport for moving)” Pg.41
  Do not touch a broken glass, but contact your dealer for repair soon.
  Did you shut the door too strongly? Compartments are connected each other by cool air paths therefore the wind pressure caused by shutting a door may open another door for just a moment.
  Have you leave the door open long time? It is because that the air taken inside is cooled and its pressure reduces temporarily. Don’t leave a door open long time. Open and shut it at each time.
  Keep it away from the back wall (2 cm or more). Pg.40
  Keep the environment clean. Put something a fruit fly hates or fruit fly can get trapped in or something like that. Cover food with the lid so that fruit flies can’t be attracted by the smell.
  Please close the door as soon as possible.
