5 1. PRECAUTIONS (SAFETY WARNINGS) ● Upon electronic Control system repair/change, make sure the set unplugged. Be ware of electric shock. ● Use rated electronic Control equipment. Make sure to check out ModeL name, Rated voltage, Rated current, Operation Temp, etc. ● Upon repair, make sure that harnesses are not to be water-penetrated and are bundled tight. Should not be detached by a certain amount of external force. ● Upon repair, completely remove dust or other foreign substances from housing, harness, connector, etc. To prevent fire by tracking, short, etc. ● Check out whether water has penetrated into the electronic Control system. If there is any kind of trace, take necessary measures such as related component change, insulation tapping, etc. ● After repair, check out the assembled state of parts. It should be the same as the previous state. ● Check out the surrounding conditions. Change the location, if the fridge is located at humid, wet places or the installed state is unstable. ● If needed, ground the fridge. Especially, if there is a possibility of electric leakage, ground is indispensable. ● Do not allow consumers to overload a certain outlet. ● Check out whether the power cord or the outlet is broken, squeezed, chopped off or heat- deformed.
