Rigging

WARNING
Heavy Objects!
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. Other lifting arrangements could cause
equipment or property damage. Failure to follow
instructions above or properly lift unit could result in
unit dropping and possibly crushing operator/
technician which 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 unit dropping and
possibly crushing operator/technician which could
result in death or serious injury and possible equipment
or property-only damage.

3. Remove the shipping crate from around the unit. Once
fork trucking is complete and unit is ready to be placed
on the curb, remove all 6 fork access brackets to drop
the shipping boards from underneath the unit. Do not
remove the crating from the top of the unit.
4. Rig the unit as shown in
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
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.
8. Downflow units; align the base rail of the unit with the
curb rail while lowering the unit onto the curb. Make
sure that the gasket on the curb is not damaged while
positioning the unit.
