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.
