RULES FOR YOUR SAFETY
1.

WARNING

TO AVOID FIRE, SHOCK, OR

SERIOUS PERSONAL INJURY

FOLLOWING THESE INSTRUCTIONS.

2. The installation must conform to local codes and
utility standards. Use the National Electric Code if
a local code does not exist.
3. Disconnect the electric power EVERY TIME you
work on your cooler. When your hands are inside
the cooler you risk injury if the cooler is accidentally
turned on from inside the home.
4. If you mount the cooler on your home roof remember
these safety tips:
5. Never install or service a cooler during a storm or
high wind conditions. You could be injured or lose or
damage parts.
6. Never wear shoes with slick soles when you work on
a roof. You may slip when you least expect it.
7. Never drain water onto a roof. Water residue may
cause you to slip or may stain your roof. Use a drain
hose to run the drain water to a rain gutter or to a
drain.
8. To avoid injury never use the cooler without connect-
ing it to a house duct system or without a sturdy fine
mesh guard over the outlet.
