HOW TO GROUND
The refrigerator should be grounded.
The purpose of grounding is to prevent any power leakage or electric shock caused by the current leakage from the
refrigerator.
Never ground to gas pipes, telephone line and lightning rod as it is very dangerous at the time of lightning strikes.
In case of outlets without ground terminals.
• Bury the ground cable connected to a copper plate into
the ground with plenty of moistures at the depth of over
25CM, or use a power source which is equipped with
circuit breakers.
