WARNING

Heavy Objects!

Do not use cables (chains or slings) except as shown. 
Each of the cables (chains or slings) 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. 
Other lifting arrangements may cause equipment or 
property-only damage. Failure to properly lift unit could 
result in death or serious injury.

WARNING

Improper Unit Lift!

Test lift unit approximately 24 inches to verify proper 
center of gravity lift point. To avoid dropping of unit, 
reposition lifting point if unit is not level. Failure to 
properly lift unit could result in death or serious injury 
or possible equipment or property-only damage.
