not remove the crating from the top of the unit.
4. Rig the unit as shown in Figure 9. Attach adequate
strength lifting slings to all four lifting brackets in the
unit base rail. Do not use cables, chains, or slings
except as shown.
5. Install a lifting bar, as shown in Figure 9, to protect the
unit and to facilitate a uniform lift. The minimum
distance between the lifting hook and the top of the
unit should be 7 feet.
6. Test-lift the unit to ensure it is properly rigged and
balanced, make any necessary rigging adjustments.
7. Lift the unit and position it into place.

Failure to follow instructions below or properly lift unit
could result in unit dropping and possibly crushing
operator/technician 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

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.
