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.
Repair or replace the defective power cord/outlet immediately.
Make sure the power cord is not punctuated or stomped down.
● Do not allow consumers to keep food unstable or place bottles in the Freezer Room.
● Do not allow consumers to repair the fridge for themselves.
● Do not allow consumers to keep things except for food.
