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

1. 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.

2. 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.

3. 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.

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

minimize the temperature increase.

5. 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.

6. Do not use brushes, acids, benzene, thinners, powdered soap, polishing powders, or hot water for

cleaning, as they can cause the painted surfaces and parts made of plastic and rubber to deteriorate.

Be especially careful not to wipe plastic or rubber parts with volatile solvents such as benzene. Rinse

off neutral detergents completely with cloth washed in clean water.

7. Fix the shelves securely. 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.

8. 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.

9. 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.

10. 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.

11. Do not stock articles beyond the load line. Containers outside the load line disturb the air circulation

in the chamber and cause poor cooling. See page 14.
