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. Too much stock will result in temperature of about -2oC around the
exhaust vent when the set temperature is 2oC. It is recommended to set the temperature to 4oC or 5oC
when a large quantity of articles that should not be frozen are stored.

• Never store corrosive materials such as acid or alkali unless the container is completely sealed up.
Corrosion may lead to failure of the unit in time.

• If the ambient temperature is fairly high, the alarm lamp is flashed, temperature display is flashed, and
the buzzer sounds at the time of initial start up. The alarm is canceled automatically when the chamber
temperature is decreased.

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

• 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.

• 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 canceled automatically when the door is
closed.

• Always open and close the door gently. Rough operation may lead fall down of stocked items,
incomplete closing, or damage of door gasket.

• In the refrigerator compartment, put the items on the shelves and do not contact the items with wall.

• The cooling pipe is routed in the rear of the freezer. Never use a knife or a screw driver, etc. to remove
the frost. They may cause damage of chamber wall or improper operation of the unit. And do not drop
any heavy items or sharp edge materials onto the freezer floor.

• Stop the freezer operation by following the procedure on page 19 “Defrosting” when the freezer is not
used or at the time of defrosting of freezer. Under such condition, the freezer is not cooled down at all.

• If an instrument requiring a power source is to be placed inside the cabinet, the cable can be lead
through the access port on the back side of the cabinet. After using of the port, a rubber cap and
insulation should be replaced to seal the access port. Failure to do this can affect the temperature
uniformity inside the cabinet and lead to condensation on the outside of the access port.

19
DEFROSTING
Refrigerator
The following 2 kinds of defrost methods are adopted for the refrigerator, which control defrosting
automatically.
1. Cycle defrost
To keep the temperature stable inside the chamber, the refrigeration compressor is cycled on and off.
During “off” periods any frost which has accumulated on the evaporator is melted by energizing a heater.
This will not have any discernible effect on the chamber temperature.
2. Forced defrost
When the ambient humidity is high, or a large amount of damp product is being stored inside the
refrigerator, there is a possibility that cycle defrost may not be enough to remove all of the frost on the
evaporator. In this case, a forced defrost cycle is initiated by the defrost sensor.
When the unit is operating under a forced defrost cycle, the current chamber temperature and “dF” is
displayed alternately on the digital temperature display.
Once the forced defrost cycle is complete, normal operation resumes. The chamber air temperature
rises up to about 10oC during the forced defrost cycle.

Freezer
Natural defrost by stopping operation.
The defrosting is performed by stopping the freezer operation.
When the frost is built-up on the freezer wall, defrost the freezer by the following procedure as the freezer
has no automatic defrosting function.
1. Temporarily move all the contents of the freezer to another freezer.
2. Set the freezer temperature to -00. The current chamber temperature and “dF” is displayed
alternately on the digital temperature display. This is the starting of defrosting.
3. When the frost on the wall has been eliminated, remove the water and wipe the inside of the freezer
completely.
4. Set the freezer temperature to desired one.
5. Once the chamber temperature has reached to the desired temperature, place the original contents
back in the freezer.
Note: The freezer does not automatically reset to normal operation.
No temperature alarm is occurred during defrosting.
