Lifting and Rigging
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
Heavy Objects!
Always place, assemble, and suspend modules/subassemblies one at a time. Do not lift units in
windy conditions. Do not raise units overhead wit personnel below unit. Failure to follow these
instructions could result in death, serious injury, or equipment damage.
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.
NOTICE
Equipment Damage!
Keep skid in place until unit is ready to set. Do not move unit or subassembly without the skid in
place as shipped from the factory. Premature skid removal may result in equipment damage.
Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety.
Because of placement of internal components, the unit weight may be unevenly distributed, with
more weight in the coil and fan areas. Approximate unit weights are provided in the
“Dimensions
and Weights” section on page 13
. Refer to the unit submittals for actual module weights. Test the
unit for proper balance before lifting.
When hoisting the unit into position, use the proper rigging method, such as straps, slings,
spreader bars, or lifting lugs for protection and safety.
•
For unit sizes 3 to 57 without base rails, use spreader bars and slings to rig units and
subassemblies as shown in
Figure 2
.
•
For unit sizes 3 to 57 with base rails, use spreader bars and slings to rig units and subassemblies
as shown in
Figure 3
.
•
For unit sizes 66 to 120, use spreader bars in conjunction with shackles attached at the base rail
lifting lugs to rig units or subassemblies as shown in
Figure 4
.
