Installation

  • Install on a completely flat and rigid surface.
  • Using the two front adjustable feet, ensure that the refrigerator is positioned firmly and level on the floor.
  • Now open the doors approximately half way, and extend the front adjustable feet equally until the doors close by themselves.
  • To ensure adequate ventilation for your refrigerator, spaces of 20mm on both sides, 50mm at the rear, and 100mm above the refrigerator are recommended.
  • Insufficient spacing will decrease cooling efficiency, resulting in unnecessary energy consumption.
  • Choose a location which is not exposed to sunlight, is relatively free from dust, heat and humidity, and offers good ventilation in order to guarantee that heat radiation will not be impaired.

Use in hot spring areas: Corrosion control treatment may be required for the refrigerant circuit (pipe) due to generation of corrosive gases. Contact the retail store where you purchased the refrigerator.

WARNING: Do not obstruct the refrigerator vents or the space around the refrigerator. If refrigerant leaks, it may accumulate and catch fire or explode.

How to remove the energy label

  • Remove the energy label carefully. A glue residue may remain, particularly if the label has been in place for a long period of time.
  • Apply either Eucalyptus or Tea Tree oil directly on any residue.
  • Do not allow the oil to run or drip onto plastic parts as it may cause the plastic to degrade and potentially crack over time. Allow the oil to sit for approximately 1-2 minutes, or until the glue residue has softened.
  • Wipe off with a damp cloth.
  • If any residue remains, repeat the above process.
  • Rinse with clear water.
  • Dry thoroughly.

During Transport

  • Before transporting, wipe dry the evaporating pan, which is located at the rear. Carry the refrigerator holding the handles located at the rear and bottom.

Do not damage the refrigerant circuit (pipes) or drive screws into it. Although R600a refrigerants are combustible, the refrigerant circuit is hermetically sealed and normally leaks will not occur.

WARNING:

Should the refrigerant circuit be damaged:

  1. Do not use flames or electrical appliances nearby.
  2. Open the windows to fully ventilate the room.
    Then, contact the retail store where you purchased the refrigerator.
Electrical Connections

Important: For personal safety, this appliance must be properly grounded.

  • The refrigerator should always be plugged into its own individual electrical outlet. This is recommended for best performance and also in order to prevent the overloading of household wiring circuits, which may cause a fire hazard. Extension cords are not recommended. Make sure that the outlet provides the correct voltage.
  • If your refrigerator has a grounding plug, use it correctly. The 3-point plug must be inserted into a mating 3-point grounded receptacle. If the installation location does not have a proper 3-point grounding wall receptacle, the proper type must be installed. The ground point should never be cut or removed.
  • If your refrigerator has an ungrounding plug, connect the ground wire to the ground connection screw provided at the lower rear side of the refrigerator.

Operation

  1. Temperature Control
    Both the freezer compartment and the refrigerator compartment have a temperature control. “MID” is recommended for normal usage. Turn the dial to “COLDER” when storing a large quantity of frozen foods, ice cream etc., in the freezer compartment. Turn the dial to “FREEZER” when only using the freezer compartment to make ice. “MID” is recommended for normal usage. If you would like items in the refrigerator compartment to be colder, turn the dial to “COLDER”. If the items are too cold or freeze in the refrigerator compartment, turn the dial to “REFRIGERATOR”.
  2. Automatic Defrosting
    The defrosting heater provides automatic defrosting in the refrigerator according to the accumulated time calculated by the microcomputer, so there is no need to defrost it manually. Water produced during defrosting passes through the drainage hose at the rear and collects in the drain pan in the lower rear part of the refrigerator. Then, it automatically evaporates with heat from the refrigerant pipe, which is utilized as a radiator.
  3. Ice-making
    • Pour water up to the water line in each of the ice tray sections. Insert the tray completely into the ice tray holder.
    • If too much water is added, the ice cubes cannot be easily separated from the ice tray.
    • Once the ice cubes have been made, turn the lever until they fall into the ice cube storage box.
    • If you attempt to make ice directly in the ice cube storage box, the box will break.
  4. Sliding Case
    • This sliding case is cooled to a low temperature in order to preserve the freshness of foods stored for long periods.
      CAUTION: Before closing the refrigerator compartment door, make sure that the sliding case is pushed all the way in (and the lid is closed correctly).
    • Remove the lid and sliding case as shown in the illustration and proceed with cleaning.
    • Pull the case out. Open the lid and then pull out holding the right and left hand sides (Fig. 1).
    • Pull the case out all the way. Pull out by holding and lifting the edge of the case upwards (Fig. 2).
  5. Door Racks
    The door racks may be used to store all those little items that seem to get in the way. If you put all the small items in one place, you’ll find that there’s more space inside the refrigerator for larger items.
    Free Pocket with Egg Tray
    • Many eggs may be stored in the free pocket (Fig. 1).
    • If you turn half the egg tray over, small items may be stored together with the eggs (Fig. 2).
    • You can even turn the whole egg tray over and store small items in the free pocket instead of eggs (Fig. 3).Bottle Pocket
    • Even large bottles may be stored in this pocket.
      Some types of commercial water cooler bottles may touch the shelf or foodstuffs when placed in the door pocket, preventing the door from closing firmly.
  6. How to Remove the Pockets
    • Remove the door racks as shown in the illustration in order to proceed with cleaning.
    • This pocket may be removed by pushing it gently upwards.
  7. Flexible glass shelf
    • To storage large or tall item
      1. Remove all food items from the Flexible shelf.
      2. Press down the Rear Shelf then pull the Front Shelf out, which the Front Shelf can be separated from the Rear Shelf. (If you have a difficulty for pulling the Front Shelf out, please press on the edge of the Rear Shelf and pull the edge of the Front Shelf out, then the Front Shelf can be easily to pull out.)
      3. Put the Front shelf on the top of Rear Shelf.
        (Caution: The Front Shelf shall be under the rail of the Food Liner.)
      4. Push the Front Shelf back to the rear, this creates more space for food storage.
  • To storage small item
    1. Remove all fool items from the Flexible shelf.
    2. Raising the front shelf slightly, then pull out forward.
    3. Push the Front Shelf back in order to take the assembly with the Rear Shelf.

CAUTION: If you take out Flexible shelf, please don’t hold vertically that make a tier drop off and cause the injury.

Maintenance

When performing maintenance, make absolutely sure that the power plug is first disconnected from the power outlet.

  • Dip a soft cloth into cold or lukewarm water, wring it out well and wipe.
  • If you do not clean the door gasket (especially the lower part) when it is dirty, the gasket will easily become damaged. Therefore, keep it clean at all times.
  • Do not clean with cleanser, acids, benzine, thinner, boiling water, soap powder, chemical cloths or neutral detergent. These will damage the paint finish and external surfaces of your refrigerator.
  • In particular, oil may lead to cracks and citrus fruit juices to discoloration, so be sure to wipe them off right away.
  • To prevent discoloration of the plastic parts, store cut citrus fruits in plastic wrap or containers.
    CAUTION: Do not apply water directly onto the refrigerator. This may result in malfunction, power leakage or fire.
  • The drain pan becomes dirty very easily and if not cleaned regularly, produces bad odours. Get into the habit of cleaning this pan regularly.

How to Replace the LED Light

  • In the event that the LED light is damaged or malfunctions, please refrain from adjusting or repairing it by yourself. Please contact the service center instead.
What to do in these situations

When there’s a power failure.
Minimize opening/closing of doors and avoid putting in more food.

W hen not in use for a long time.
Clean the Ice cube box and Ice tray, clean the interior after unplugging the refrigerator, and keep the door open for 2 – 3 days to let it get dry. If not allowed to dry properly, mold and odors can occur, or refrigerant (gas) may leak due to corrosion of the cooling unit.

When transporting.

  1. Discard the water/ice from the Ice cube box and the Ice tray.
  2. Use protective gear (protective gloves).
  3. Lay towels under the water discharge outlet and under the back corners of the refrigerator, and place a container or tray on the floor that’s about 3 cms high to catch water. Towels prevent water from spilling on the floor and damage to the floor.
  4. Slowly tilt the refrigerator back to an angle of over 30 degrees, discharge water of the evaporator tray through the water discharge outlet (the evaporator tray is not visible from the outside.)
    • Have 2 or more persons do this work because the unit is heavy.
    • Avoid having young children or those without confidence do this work. Please seek advice from a moving company.
  5. With more than 2 persons, calmly and slowly transport the unit by grasping the front side’s lower section inner edge and the back side’s upper section handle.
    Do not lay or load on its side (it will cause damage to the compressor.)

When moving the unit / when changing the direction of the unit.

  1. Lift the adjustable legs.
  2. Move in a forward or backward direction. If moved other than a in forward or backward direction, there’s a risk of damaging the floor.
  3. When changing the direction of the unit, please use caster wheels or place a protective cloth under the back legs.

WARNING: Do not damage the refrigerant circuit, do not drive in screws, etc. The unit uses a flammable refrigerant, so if the gas leaks out, there is the risk of ignition or an explosion.

Troubleshooting

When the refrigerator fails to operate

  • Check for a power failure.
  • Check if the power cord is plugged into the power outlet.
  • Check that the fuse (or circuit-breaker) has not blown

When the refrigerator is cooling excessively

  • The temperature control dial may be set too high.
  • If you place foodstuffs containing a lot of moisture directly under the cool air outlets, they will freeze easily.  This does not indicate a malfunction.

When you hear a sound similar to flowing water

  • The sound of flowing water is the flow of refrigerant (cooling gas). This does not indicate a malfunction.

When noise is produced by the fan grill of the refrigerator

  • The noise produced by the fan grill will stop at a certain fixed temperature. The airflow cooling system inside the refrigerator is powered by the operation of the fan motor and fan grill.

When noise is produced while the refrigerator door is open

  • When you open a door panel, plastic components switch swiftly between hot and cold, and this may produce noise. When the door is closed, the noise will remain until the difference in temperature is reduced.

When the refrigerator is not cooling sufficiently

  • The food may be packed too tightly together, which blocks the flow of cool air.
  • You may have put hot or too many items into the refrigerator.
  • The door may not have been closed properly.
  • The door gasket may be damaged.
  • The refrigerator may not be well-ventilated.
  • There may be insufficient clearance between the refrigerator and the surfaces immediately beside and above.
  • The temperature control dial may not be properly set.

When the front of the refrigerator cabinet heats up

  • In order to safeguard against condensation, there is an anti-condensation pipe which heats up the front of the cabinet when actuated. When the front of the cabinet is warm, this does not indicate a malfunction. The more often the door is opened and closed, the more often the anti-condensation pipe is actuated. It is also actuated immediately after the refrigerator has been installed. In other words, the front of the cabinet often heats up.

When condensation forms on the exterior of the refrigerator

  • Condensation may form on the exterior when humidity is high, such as during the wet season. This is comparable to condensation forming on the outside of a glass when chilled water is poured in; therefore, it does not indicate a failure. Wipe dry with a dry cloth.

When the power plug is disconnected and reconnected, and the compressor ceases to rotate

  • When the power plug is disconnected from the power outlet and then immediately plugged in again, the compressor may not restart. Therefore, when unplugging the refrigerator, always wait at least 5 minutes before plugging it in again. If the compressor ceases to rotate completely, keep the refrigerator unplugged and wait at least 5 minutes before plugging it in again.

When the side panel of the cabinet heats up

  • The side panel of the cabinet will heat up when the door is opened and closed frequently, when installing the unit and when the unit operates in summer in high temperatures. In such cases, do not touch the panel. This heat buildup is due to the dissipation of heat absorbed from inside the cabinet over the whole of the side panel and does not indicate something wrong with the unit.

CAUTION

  1. This appliance is designed for use in ambient temperature listed below.
    MODEL NAME AMBIENT TEMPERATURE RANGE CLIMATIC CLASS
    MR-458ER/ERL, 505ER/ERL-A 16 oC ~ 43 oC T
    MR-458ER/ERL, 505ER/ERL-NZ 16 oC ~ 43 oC T
         

    The internal temperatures could be affected by such factors as the location of the refrigerating appliance, ambient temperature and the frequency of door opening, and, if appropriate, a warning that the setting of any temperature control device might have to be varied to allow for these factors.

  2. A rise in temperature of the frozen food during manual defrosting, maintenance or cleaning could shorten the storage life.
  3. Food to be frozen is not to be placed in direct contact with food in storage and, if appropriate, that it could be necessary to reduce the quantity to be frozen if freezing every day is anticipated.
  4. The electrical power failure for 1-2 hour will only slightly effect the inside temperature. However, open & close of the door results in the temperature loss. In case there is more than 24 hours electrical power failure, the food should be taken out from the fridge.
