Symbol shows;
this symbol means caution.
this symbol means an action is prohibited.
this symbol means an instruction must be followed.
Be sure to keep this manual in a place accessible to users of this unit.
< Label on the unit >
This mark is labeled on the cover in which the electrical components of high voltage are
enclosed to prevent the electric shock.
The cover should be removed by a qualified engineer or a service personnel only.

PRECAUTIONS FOR SAFE OPERATION
Do not use the unit outdoors. Current leakage or electric shock may result if the unit is exposed to
rain water.
Only qualified engineers or service personnel should install the unit. The installation by
unqualified personnel may cause electric shock or fire.
Install the unit on a sturdy floor. If the floor is not strong enough or the installation site is not
adequate, this may result in injury from the unit falling or tipping over.
Never install the unit in a humid place or a place where it is likely to be splashed by water.
Deterioration of the insulation may result which could cause current leakage or electric shock.
Never install the unit in a flammable or volatile location. This may cause explosion or fire.
Never install the unit where acid or corrosive gases are present as current leakage or electric
shock may result due to corrosion.
Use a dedicated power source as indicated on the rating label attached to the unit. Ensure that a
suitable fuse of adequate amperage is used to allow for compressor start up.
Remove dust from the power supply plug before inserting in a power source. A dusty plug or
improper insertion may pose a hazard.
Use a power supply outlet with ground (earth) to prevent electric shock. If the power supply
outlet is not grounded, it will be necessary to install a ground by qualified engineers.
Never ground the unit through a gas pipe, water main, telephone line or lightning rod. Such
grounding may cause electric shock in the case of an incomplete circuit.
Do not insert metal objects such as a pin or a wire into any vent, gap or any outlet for inner air
circulation. This may cause electric shock or injury by accidental contact with moving parts.
Never store volatile or flammable substances in this unit. This may cause explosion or fire.
Never store corrosive substances in this unit. This may lead to damage to the inner components
or electric parts.
If this unit is to be used for storing poisons, radioactive material or other harmful products,
ensure that it is in a safe area. Failure to do so may lead to an adverse effect on the health of
personnel in the area and the local environment. In this case, a request for repair or maintenance
will necessitate a safety check sheet for maintenance personnel.
WARNING

PRECAUTIONS FOR SAFE OPERATION
Disconnect the power supply to the unit prior to any repair or maintenance of the unit in order to
prevent electric shock or injury.
Ensure you do not inhale or consume medication or aerosols from around the unit at the time of
maintenance. These may be harmful to your health.
Never splash water directly onto the unit as this may cause electric shock or short circuit.
Never disassemble, repair, or modify the unit yourself. Any such work carried out by an
unauthorized person may result in fire or injury due to a malfunction.
Disconnect the power supply plug before replacement of the florescent light to prevent electric
shock.
Disconnect the power supply plug if there is something wrong with the unit. Continued
abnormal operation may cause electric shock or fire.
If the unit is to be stored unused in an unsupervised area for an extended period, ensure that
children do not have access and that doors cannot be closed completely.
The disposal of the unit should be undertaken by appropriate personnel. Remove doors to
prevent accidents such as suffocation.
Prepare a safety check sheet when you request any repair or maintenance for the safety of service
personnel.
Do not pull out more than 2 drawers at the same time when storing or taking out of the stocked
material. This may cause injury by falling or tipping of the unit if something heavy items are stored.
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.
Never install the unit in a place where the possibility exists that an object may fall on it. There
are cooling circuits and electric components in the upper part of this unit. Current leakage or electric
shock may be caused if an object falls on it.
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.
WARNING
CAUTION

PRECAUTIONS FOR SAFE OPERATION
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 put a container with water or heavy articles on the unit. Injury may be caused if the
articles fall. Current leakage or electric shock may result from the introduction of spilled water into
electrical components.
Do not climb onto the unit. This may cause damage to the unit and cause it to tip over.
Hold the handle when closing the door. This will reduce the likelihood of a trapped finger.
Do not lean on the door. This may cause injury if the unit tips over.
Never place your hand on the glass or use excessive force on the glass. Intentional force may
break the glass resulting in injury from the broken glass.
Do not touch the condenser directly when the filter is removed for cleaning. This may cause injury
due to hot surface.
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 any water in the evaporation tray completely before moving the unit. Spilled or
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

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.
