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. Use standard electrical components.
5. Don't touch metal products in the freezer with wet
hands. This may cause frostbite.
6. Prevent water from spiling onto electric elements or the
machine 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. Service on the refrigerator should be performed by a
qualified technician. Sealed system repair must be
performed by a CFC certified technician.
