Installation
Improper Unit Lift!
Do not lift the unit from top! Lift from lifting lugs only located at bottom of unit. 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.
Heavy Objects!
Follow good lifting practices before lifting the unit, such as estimating center of gravity and test
lifting the unit to check for balance and stability. 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 could result in death or serious injury, and equipment or property damage.
