SAFETY AND PRECAUTIONS
1) For starters, be sure to check any chances of the leakage of electricity.
2) You could handle a part in the vicinity of electricity after unplugging.
3) You should put on rubber glovers to prevent an electric shock on operation test.
4) Make sure the rated current, voltage, capacity before using an instrument.
5) Keep your wet hands away from the metal goods in the freezer compartment not to be frostbitten.
6) Be careful not to let water to permeate the electric part in the machine room.
7) With the door open during your working, you might be damaged by that door.
8) You should give a title to the refrigerator for your safe after removing the breakable goods inside the refrigerator.
9) You'd better use cotton gloves if you fix it up around the evaporator.
