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 unless the container is completely sealed up.  
Corrosion may lead to failure of the unit in time.  
4. If the ambient temperature is fairly high, the alarm lamp is flashed, the buzzer sounds, and the  
temperature display is flashed at the time of initial start up. The alarm is canceled automatically when  
the chamber temperature is decreased.  
5. Once the chamber temperature has stabilized, put the items into the chamber in small batches to  
minimize the temperature increase.  
6. 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.  
7. 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.  
8. Always open and close the door gently. Rough operation may lead fall down of stocked items,  
incomplete closing, or damage of door gasket.  
9. 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.  
10. Do not drop any heavy items or sharp edge materials onto the freezer floor.  
11. Move the freezer switch to OFF position when the freezer is not used or at the time of defrosting of  
freezer. In the OFF condition, the freezer is not cooled down at all.  
12. 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 left hand side of the cabinet. After installation, a rubber cap should be  
used 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.  
13. 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 solvents. When a neutral detergent is used to clean the unit,  
wipe it up thoroughly with a cloth soaked in clean water.  
14. If condensation forms on the front glass or frame surface, wipe it off with a dry soft cloth.

OPERATING INSTRUCTIONS  
Defrost cycles  
Refrigerator  
There is no need for routine defrosting of the unit as this occurs automatically as follows:  
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 refrigeration coils is melted by energizing a  
small heater. This will not have any discernible effect on the chamber temperature.  
2. Forced defrost  
When the set temperature is low, 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 refrigeration coils. In this case, a forced defrost cycle can be initiated.  
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 temperature rises  
to about 10oC during the forced defrost cycle.  
Freezer  
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. Turn the freezer switch to “OFF”.  
3. When the frost on the wall has been eliminated, remove the water and wipe the inside of the freezer  
completely.  
4. Turn the freezer switch to “ON”.  
5. Once the chamber temperature has resumed normal set-point temperature, place the original contents  
back in the freezer.  
Note: The freezer does not automatically reset to normal operation.  
15  
 
TEMPERATURE RECORDER
