Please read the following instructions before servicing your
refrigerator.
1. Check the refrigerator for electrical faults.
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 or cause your skin to
freeze and stick to the surfaces inside the freezer.
6. Prevent water from flowing 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 glass shelves and stored
foods.
9. When servicing the evaporator, wear cotton gloves.
This is to prevent injuries from the sharp evaporator
fins.
10. Disassembly, repair, and servicing the sealed
refrigeration system should be performed only by
qualified and certified personnel. Refrigerant should
not be vented into the atmosphere; proper recovery
equipment should be used.
