SAFETY PRECAUTIONS

Please read the following instructions before servicing your
refrigerator.
1. Check the refrigerator for current leakage.
2. To prevent electric shock, unplug before servicing.
3. Always check line voltage and amperage.
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 following onto electric elements in
the mechanical parts.
7. Close the top door before opening the bottom door.
Otherwise, you might hit your head when you stand up.
8. When tilting the refrigerator, remove any materials on
the refrigerator, 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.
