WARNING
Heavy Object!
Failure to follow instructions below could result in
unit dropping which could result in death or serious
injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings)
may not be of the same length. Adjust as necessary
for even unit lift.
WARNING
Improper Unit Lift!
Failure to properly lift unit in a LEVEL position could
result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only
damage.
Test lift unit approximately 24 inches (61 cm) to verify
proper center of gravity lift point. To avoid dropping of
unit, reposition lifting point if unit is not level.
