Safety Instructions
Read this manual carefully and understand the contents
before you install and operate the refrigerator.
Be aware of possible safety hazards when you see the safety
alert symbol on the refrigerator and in this manual. A signal
word follows the safety alert symbol and identifies the danger
of the hazard. Carefully read the descriptions of these signal
words to fully know their meanings. They are for your safety.

which if ignored, can cause dangerous personal injury,
death, or much property damage.
CAUTION:
