Read all instructions before using this appliance in order to avoid risk of accident or possible damage.
Warning/Caution Description of symbols
Indicates prohibition
Do not disassemble
Do not contact
Follow Adhere the instruction strictly
Unplug from the electrical outlet
Earth the appliance to avoid the
risk of an electric shock
Do not plug multiple electrical
appliances into the same outlet.
• This may cause abnormal
heating or a fire hazard.
Do not attempt to make repairs
yourself.
• This could lead to fire hazard or
abnormal operation causing
severe personal injury.
Make sure the power cord is not
crushed or damaged.
• Repair immediately all power cords
or outlets that have become frayed
or otherwise damaged.
Check the operating environment.
• Do not install the refrigerator in a
humid (with condensation) location
or on an unstable surface.
Be sure the earth.
• If earthing is not done, it will
cause breakdown & electric
shock.
Pull the power plug out for
exchanging electrical equipment.
• It may cause electric shock.

• Freezing of the contents
may inflict a wound.
Do not store narrow and
lengthy bottles or foods in a
small multi-purpose room.
• It may hurt you when refrigerator
door is opened and closed
resulting in falling stuff down.
Do not store pharmaceutical
products, scientific materials,
etc, in the refrigerator.
• The products which cotrolled by
temperature shall not be stored
in the refrigerator.
Do not store articles on the
product.
• Opening or closing the door
may throw down which may
inflict a wound.
Use the rated components on
the replacement.
• Check the correct model, rated
voltage, rated correct, operating
temperature and so on.
On repair, make sure that the wires
such as harness should be bundled
tightly.
• Bundle tightly wires in order not to
be detached by the external force
and then not to be wet.
On repair, remove completely
dust or other things of housing
parts, harness parts, and check
parts.
• Cleaning may prevent the possible
fire by tracking or short
After repair, check the assembled
state of components.
• It must be in the same assembled
state when compared with the
state before disassembly.
Check if there is any trace indicating
the permeation of water.
• If there is that kind of trace, change
related components or do the
necessary treatment such as taping
using the insulating tape.
