SAFETY PRECAUTIONS

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 or cause your skin to freeze and stick to the surfaces inside the freezer.

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 glass shelves and stored food.

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.
