    CAUTION
    Failure to heat the fan hub in hot tap water before installation will result in cooling fan failure due to cracking. Allowing the heated fan to cool for more than one minute prior to installation will also result in failure due to cracking.


    NOTE
    Using hot tap water at a minimum of 49° Celsius 120 Fahrenheit, hold the new fan blade hub under the running water for a minimum of 60 seconds to hear the fan blade to the temperature of the water. Immediately after heating, position the fan blade on the fan motor drive plate.

    CAUTION
    If a fan blade is bent or damaged in any way, do not repair or reuse the damaged part. Always replace a bent or damaged fan blade. Fan blades that have been damaged can not be assured of proper balance and could fail and fly apart during subsequent use. This creates an extremely dangerous situation. The fan blades must remain in proper balance. You cannot assure fan blade balance once a fan blade has been bent or damaged. A fan blade that is not in proper balance could fail and fly apart during use, creating an extremely dangerous situation.
