PRECAUTIONS FOR SAFE OPERATION
CAUTION
Select a level and sturdy floor for installation. This precaution will prevent the unit from tipping.
Improper installation may result in water spillage or injury from the unit tipping over.
Connect the unit to a power source as indicated on the rating label attached to the unit. Use
of any other voltage or frequency other than that on the rating label may cause fire or electric shock.
Fix the shelves securely. Incomplete installation may cause injury or damage.
When removing the plug from the power supply outlet, grip the power supply plug, not the cord.
Pulling the cord may result in electric shock or fire by short circuit.
Never damage or break the power supply plug or cord. Do not use the supply plug if its cord is loose. This may cause fire or electric shock.
Do not touch any electrical parts such as the power supply plug or any switches with a wet hand. This may cause electric shock.
Do not climb onto the unit or do not put articles on the unit. This may cause injury by tipping or
damage to the unit.
Do not store bottle or cans in the freezer. This may cause injury by broken of containers due to the frozen.
Do not touch any stock (especially metal objects) in the freezer with a wet hand. This may cause frostbite.
Always hold the handle when closing the door. This will reduce the likelihood of a trapped finger.
Never lean or press on the glass. Intentional force may cause injury if the glass breaks.
Do not lean on the door. This may cause injury if the unit tips over.
Always disconnect the power supply plug before moving the unit. Take care not to damage the 
power cord. A damaged cord may cause electric shock or fire.
Dispose of water in the evaporation tray completely prior to the movement. Spilled water or
splashed water may cause current leakage or electric shock.

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. 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.
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, 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.
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.In the refrigerator compartment, put the items on the shelves and do not contact the items with wall.
10.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.
11.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.
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 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.
