SAFETY PRECAUTIONS

Please read the following instructions before servicing your
refrigerator.
1. Check the set for electric leakage.
2. Unplug prior to servcing to prevent electric shock.
3. Whenever testing with power on, wear rubber gloves to
prevent electric shock.
4. If you use any kind of appliance, check regular current,
voltage, and capacity.
5. Don't touch metal products in the freezer with wet
hands. This may cause frostbite.
6. Prevent water from flowing onto electric elements in the
mechanical parts.
7. When standing up after having checked the lower
section of the refrigerator with the upper door open,
move with care to avoid hitting the upper door.
8. When tilting the set, remove any materials on the set,
especially the thin plates (ex. glass shelf or books.)
9. When servicing the evaporator, wear cotton gloves.
This is to prevent injuries from the sharp evaporator
fins.
10. Leave the disassembly of the refrigerating cycle to a
specialized service center. The gas inside the circuit
may pollute the environment.
