is loose. This may cause fire or electric shock.

Do not touch any electrical parts such as the power supply plug or any switches with a wet hand.

This may cause electric shock.

Do not put a container with water or heavy articles on the unit. Injury may be caused if the

articles fall. Current leakage or electric shock may result from the introduction of spilled water into

electrical components.

Do not climb onto the unit. This may cause damage to the unit and cause it to tip over.

Hold the handle when closing the door. This will reduce the likelihood of a trapped finger.

Do not lean on the door. This may cause injury if the unit tips over.

Never place your hand on the glass or use excessive force on the glass. Intentional force may

break the glass resulting in injury from the broken glass.

Do not touch the condenser directly when the filter is removed for cleaning. This may cause injury

due to hot surface.

Disconnect the power supply plug before moving the unit. Take care not to damage the power

cord. A damaged cord may cause electric shock or fire.

Dispose of any water in the evaporation tray completely before moving the unit. Spilled or

splashed water may cause current leakage or electric shock.

Be careful not to tip the unit over during movement to prevent damage or injury.

Disconnect the power plug when the unit is not used for long periods.

Do not put the packing plastic bag used in the packaging within reach of children as suffocation

may result

CAUTION

CAUTIONS FOR USAGE

•If the unit is unplugged or the power to the unit is interrupted, do not restart the unit for at least 5

minutes. This protects the compressor.



•This inner cabinet is refrigerated by the forced circulation of cooled air inside the chamber. Ensure that

the intake and exhaust vents are not blocked. Adequate space should be provided between the items

inside the unit to allow air circulation.



•Never store corrosive materials such as acid or alkali where the container is not completely sealed.

This could possibly lead to corrosion of the evaporator resulting in refrigerant leakage and subsequent

loss of cooling ability.



•Once the chamber temperature has stabilized, put the items into the chamber in small batches to

minimize the temperature increase.



•In the case where condensation forms on the front of the glass due to high ambient humidity, wipe it off

with a soft and dry cloth.



•For the cleaning of the unit, use a cloth containing diluted neutral dishwashing detergent (Undiluted

detergent may break the plastic parts. For the dilution, follow the instruction enclosed with the

detergent). When a diluted neutral dishwashing detergent is used to clean the unit, wipe the unit

thoroughly with a cloth soaked in clean water. Then wipe the unit with a dry cloth to eliminate the

moisture.

•Do not clean the unit with scrubbing brushes, acid, thinner, solvents powdered soap, cleanser or hot

water. These agents can scratch the paint or cause it to peel. Plastic and rubber parts can be easily

damaged by these materials. Especially never use any volatile solvent to clean the plastic or rubber

parts.



•Fix the shelves securely (MBR-304D, MBR-304G). Place items on the shelves and leave a space

between the walls of the cabinet and the contents to allow air circulation. Do not place items on the floor

of the chamber.



•Always close the door firmly. The door check lamp is lit when the door is open. The alarm buzzer

sounds two minutes after door opening. The buzzer can be cancelled automatically when the door is

closed.



•Always open and close the door gently. Rough handling of the unit may lead to stocked items tipping

over, incomplete closing of the door, or damage to the door gasket.



•Do not put any articles on the unit. Blocking of the top will decrease the heat discharge which can

cause poor cooling and failure of the unit.
