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.
