General Lifting Considerations
WARNING
Risk of Unit Dropping!
Always place, assemble, and suspend modules/
subassemblies one at a time. Placing, assembling, and/
or suspending more than one module/subassembly at
a time could result in module/subassemblies dropping
and crushing technicians which 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 unit dropping and
possibly crushing operator/technician which could
result in death or serious injury and possible equipment
or property-only damage.
:
NOTICE
Equipment Damage!
Keep skid in place until unit is ready to set. Do not
move the unit or subassembly without the skid in
place as shipped from the factory. Premature skid
removal could 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
"Dimensions and Weights," p.
submittals for actual section weights. Test the unit for
proper balance before lifting.

For outdoor air handlers, preparation of the roof curb or
pier mount and roof openings must be completed before
lifting to the roof. See CLCH-SVN04A-EN Roof Curbs for
Performance Climate Changer Air Handlers installation
instructions for details.
Heavy Objects!
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
Clearance
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.
Always rig subassemblies or sections as they ship from
the factory. Never bolt sections together before rigging.
•
Make the loop of the sling parallel to the direction of
airflow, if possible.
•
When hoisting the unit into position, use the proper
rigging method, such as straps, slings, spreader bars,
or lifting lugs for protection and safety.
•
Use all lifting lugs provided. See submittal
documentation for unit lifting lug size. Use field-
provided spreader bars and slings to rig units and
subassemblies as shown in
not designed to be lifted or rigged from the top of the
unit.
