Comparison of storage in the new R-X7300F (equivalent to R-F7300XS and R-F7300XM) Vacuum Compartment (Vacuum Sub Zero mode) and the Vacuum Compartment (Vacuum Sub Zero mode) of the previous year's R-G6700X. Outside temperature of 20°C, with items wrapped in polyvinyl chloride bags, and with no door opening/closing. Water and gases can permeate polyvinyl chloride bags so whether items were wrapped or not did not in�uence the effect of Vacuum Preservation or Platinum Preservation. The effect differs depending on factors such as the type and freshness of food. The effect does not extend best-before and expiration dates, and does not guarantee the indicated shelf life.

The vacuum compartment removes air from stored food, allowing the seasoning to be absorbed at a faster rate*2 so that less time is required in food preparation.

Freshness Preservation with new Platinum Catalyst 2 Temperature Zones

Hitachi Original Vacuum Preservation*1Introducing Vacuum Preservation technology with Platinum Power Catalyst to keep food fresh for longer.

Platinum CatalystOdour components that come intocontact with the catalyst are broken down into carbon dioxide and water.

Odour components from meat and �sh are broken down by the Platinum Catalyst to generate a greater amount of carbon dioxide than the conventional photocatalyst. The carbon dioxide dissolves in water on the surface of food items to make the surface acid level weaker. This suppresses enzyme strength to minimize loss of freshness.

Selecting the Vacuum Sub Zero mode for items such as meat, �sh and processed food, and the Vacuum Chiller mode setting for items such as vegetables and tofu lets you store food without freezing them. This helps to prevent deterioration of �avour and texture due to freezing.

Platinum Catalyst generates carbon dioxide

Carbon dioxide dissolves in water on the food surface, making it less acidic and suppresses the enzyme action.

Platinum CatalystEffect of Platinum Catalyst in the Aero-care Vege and Vacuum Compartments based on joint research with Hokkaido University

Highly ef�cient even at low temperatures, the Platinum Catalyst developed by Hokkaido University breaks down ethylene and odour components inside the refrigerator into carbon dioxide. By maintaining a higher concentration of carbon dioxide than that in the air, Platinum preservation suppresses respiration of vegetables, and the action of enzymes on the surface of meat and �sh to retain freshness and nutrients.

Professor Atsushi Fukuoka, Catalysis Research Centre, Hokkaido University

Tests were conducted in Japan, using Japanese domestic models. Comparison of the level of freshness and nutrients of food placed inside the new model R-X6700E (equivalent to R-E6800XM) Refrigerator Compartment and the Vacuum Compartment (vacuum environment at -1°C setting) and the previous year’s model R-G6700D Vacuum Compartment (vacuum environment at -1°C setting, but without release of anti-oxidant components). The taste and texture of food placed inside the new model R-X6700E’s Refrigerator Compartment and Vacuum Compartment (vacuum environment at -1°C setting), and the Vacuum Compartment (vacuum environment at -1°C setting, but without release of anti-oxidant components and pungent components) of the R-C6700, which is a model from 2 years ago, are compared. The room temperature outside the refrigerator was 20°C and the food items were wrapped with polyvinyl-chloride wrap, without opening/closing of the doors. Water or gas is able to permeate the polyvinyl-chloride wrap, thus even with or without the wrap, there is no influence on vacuum storage or Aero-care storage effects. The effects differ depending on the type, and freshness of food items stored. It does not have the effect of extending the expiry date, and we don’t guarantee that the food will definitely be kept fresh during the stipulated storage period.

Food in Vacuum Compartment

The anti-oxidant components emitted from the Fresh Cassette are oxidised in place of the nutrients in food items, thus protecting and maintaining the freshness of food.

The wasabi component emitted from the cassette inhibits enzyme activity on the surface of food, maintaining the texture and taste of food.

Aero-care Vege Zone maintains the freshness of vegetables

Vegetables continue to respire even when they are refrigerated. As the temperature falls inside the Aero-care Vege Zone and the concentration of carbon dioxide increases, however, vegetables respire more slowly. In such conditions the deterioration of vegetables is suppressed, and as a result, the loss of freshness is limited. Preserving vegetables using a high concentration of carbon dioxide is a method also used in vegetable warehouses and other storage facilities.

Professor Kazuhiro FujiwaraGraduate School of Agricultural and Life Sciences, The University of Tokyo

Aero-care Preservation alters the air to control the respirationof vegetables and maintain their freshness and nutrients.

Increase in carbon dioxide concentration

As the concentration of carbon dioxide increases in the Aero-care Vege Zone, vegetables respire more slowly and there would be limited consumption of nutrients and release of moisture by vegetables.

Generation of carbon dioxide

Photocatalystand LED lights

When in contact with a Photocatalyst and exposedto light, ethylene gas or odours emitted by vegetables are broken down, producing carbon dioxide, which is also released from the respiration of vegetables.

HFC-Free Polyurethane Insulation / HFC-Free Refrigerant (R600a)

Environment-friendly HFC-Free featuresTaking the environment into consideration, hard urethane insulation made using HFC-Free insulation foaming gas (cyclopentane) as a foaming agent is used for insulating parts that are not vacuum insulated. The HFC-Free refrigerant R600a, which has minimal effects on global warming compared to HFC-alternative R134a, is used.

Cuts power consumption by about 10 –12% compared to that during regular operation. (Room temperature of 15°C – 30°C)*2

• LED Lighting (inside the refrigerator) Lighting dims when the door has been left open for 30 seconds, to prompt the user to quickly shut the door.

• Temperature (in each compartment) Slowly cools the compartment without affecting food preservation.

• Controlled Compressor Operation Lowers the rotation speed of the compressor.

• Door Alarm The alarm sounds when door has been left open for 30 seconds. In normal mode, alarm only sounds when door has been open for 1 minute.

In Save Mode, cooling power is lowered so you might feel that the cooling effect in the refrigerator is weak,

although it is limiting the consumption of energy.

Indications for smart use

This will light on when operation is comparatively stable. The light turns off when there is a heavy load on the refrigerator such as during rapid freezing.

In conventional cooling systems, the frost formed on the evaporator simply melts and is discarded. In Frost Recycling Cooling with Hybrid Defrost*1, chilled air generated by frost is recycled by being sent to the Refrigerator and Vegetable compartments to cool them even when the compressor is not running. Through this system, energy consumption is reduced.

Heater

With the Hitachi Original Frost Recycling Cooling System with Hybrid Defrost, two heaters are used to defrost, thus speeding up the defrosting process.

*1 Hybrid Defrost is applicable to R-F7300XM and R-F5200M.

High-Efficiency Inverter Compressor

Compact but high powered The high-precision, high-durability inverter compressor finely adjusts cooling power from high to low. It is capable of providing exceptionally powerful cooling by generating a large volume of chilled air, while also providing efficient low cooling.

Depending on conditions inside and outside the refrigerator, it provides optimum cooling power at all times. • This data was tested by using Singapore model and Singapore energy rating system.

Quick Freezing

Preserves food at a lower temperature than regular freezing method, setting the temperature in the freezer compartment to maximum*1.

*1 Temperature settings of freezer compartment is set to “strong”. Compared with the regular freezing method, the energy consumed is 20% higher. Based on experiments conducted by Hitachi.

Low Temperature Freezing

*Note1: Hot food items can be separately wrapped and placed lying �at on the surface, and �xed to the aluminium tray before freezing. The time taken for the food item to freeze completely will depend on the food item’s temperature and quantity, and the temperature of surrounding food items may increase. If a 60°C food item that weights 450g is placed under powerful freezing, the electricity consumed is around 20% (calculated value) more than during the approximately 90 minutes of powerful freezing, compared to cooling the food item to 20°C before powerful freezing. Based on testing conditions done at Hitachi.

Comparison of the state of bamboo shoot between storing in the freezer for 16 hours, and thawing for 4 hours at a room temperature of 20°C. Based on experiments conducted at Hitachi. The effect will differ depending on the type of food item, freshness level, state of packaging, and the thawing method.

Tank Type Automatic Ice-MakerYou can enjoy clean ice anytime from bottled water that goes through the water �lter. No troublesome plumbing is required, as the unit does not need to be connected to a tap. The water pump and pipe are maintenance free.

Make ice automatically by simply �lling up the water supply container of the Ice-Maker Compartment. No plumbing required.

*3 Time taken to make ice once (12 cubes) without opening the door based on room temperature outside the refrigerator being 30°C. Ice-making capabilities are affected by the frequency of door- openings and the room temperature. If quick ice-making is used once a day (around 7 hours), the energy consumed will be 30% (calculated value) higher than normal ice-making. This is based on testing conditions done by Hitachi.

Conventional Ice-Making120 minutes

Quick Ice-Making80 minutes*³

Quick Ice-MakingWith the Quick Ice-Making function, it only takes 80 minutes for ice cubes to form as compared with conventional ice-making at 120 minutes.

• Indicator shows low water level decrease in water supply container

• Stop Ice-Making You can deactivate the ice-making function if you are going to be away for a long period of time.

• Ice-Maker Cleaner When using it for the first time, the ice-maker washes away dust from the ice making tray and the water supply pathways.

*2 Recommended to use water with a hardness level below 100mg/L. If you use mineral water, white suspended solids will be mixed in the ice. However, this would not affect the water’s drinkability since the minerals are trapped in the ice.

Small Item Storage Space(Only in R-F7300XM)

With a transparent lid for easy identi�cation for neat storage of small items such as ice cream.

During Quick Freezing, chilled air is sent to the freezer compartment to freeze items at a rapid rate. By placing food on the Aluminium Tray, food chills faster due to quick conductivity of the metal.

Simply press the ‘Powerful’ button to increase the cool air�ow, allowing Quick Freezing to start.

• The measurements and rated capacities are based on the R-F7300XS (equivalent to R-F7300XM) using a 22L capacity basket. Total storage capacity of the upper and lower sections of the freezer compartment is approx. 118L. Ice making compartment is not included.

• Ice cream and other items with a high fat content stored in the freezer compartment's upper section or in the thin item case in the lower section may become soft. If this happens, please move the items to the large item case in the freezer compartment's lower section.

Also ideal for storing separate amounts of partially used items.

Place items on the aluminium tray taken from the upper section of the

freezer compartment to also use as a rapid freezing space.

Ideal for items often put in and taken out every day.

Scratch-Resistant Crystal DoorsTouch Screen Controller

Usually, the refrigerator projects a re�ned appearance with no visible control panel. Touch the MENU button and the control panel display appears on the �at surface of the door, so you can control your settings without having to open the door.

Convenient Installation

The left and right corners of the door surface are rounded, so they don't protrude outward very much when the doors are open. This design feature lets you match the refrigerator doors with built-in kitchen units and the fronts of other items of furniture for a �at layout. And you can enjoy neat installation close to a wall without requiring a lot of space to enable opening and closing of the doors.

• This function reduces the initial burden of opening the doors, but does not fully open them

• Depending on installation conditions, the opening angles of the doors may differ

• You can switch off the Auto function to open the doors manually

• The Auto function does not work when either the ice-maker or upper freezer compartment drawers are open.

• The control panel switches off when not in use. However, the following settings will be displayed when activated: eco operation sign, water supply, door open/close (frequent opening/closing), energy saving, quick ice making, ice making stopped, quick chilling, quick freezing.

• This function reduces the initial burden of opening the drawers but does not fully open them. When the function is activated, the drawers slide out about 15cm or more

• Depending on installation and other conditions, the distance the drawers slide out may differ, and sometimes they may automatically close after opening

• You can switch off the Auto function to open the drawers manually

• The Auto function opens either the lower freezer compartment drawer or the vegetable compartment drawer, but not both at the same time

• The vegetable compartment drawer may sound loud when sliding in and out.

DESIGNED TO PERFECTION

* If a wall or item of furniture is located in front of the refrigerator leaving insuf�cient space, the refrigerator compartment doors cannot be fully opened. Please make sure there's enough space at the side of the refrigerator to enable radiation of heat.
