13. Safety Instructions on Service

Unplug the refrigerator before making any repair or any replacement. Avoid the electric shock.

Use the rated components on the replacement.

Check the correct model number, rated voltage, rated current, operating temperature and so on.

On repair, be sure that the wires such as harness are bundled tightly and are not exposed by water.

Bundle wires tightly in order not to be detached by the external force.

On repair, remove completely dust, particles or other things on housing parts, harness parts, and connectors.

Cleaning may prevent fire by tracking or short.

Check if there is any trace indicating the infitration of water on electrical parts.

If there is, kind of trace, change the related components or do the necessary action such as taping using the insulating tape.

After repair, check the assembled state of parts.

It must be the same assembled state when compared with the state before disassembly.

Check the surrounding conditions of the installed refrigerator.

When the refrigerator is located at humid or wet place, or the installed state is unstable, change the location.

If needed, do the ground.

Especially, if there is a possibility of the electric leakage, this appliance must be properly grounded.

Do not allow consumers to use one outlet for several plugs.

Check whether the power cord is placed under other appliance and so, damaged, worn-out, and squeezed.
