Ddp Fan Thrust Bumper; General Lifting Considerations - Trane CSAA Installation, Operation And Maintenance Manual

DDP Fan Thrust Bumper

Confirm bumpers are not attached to the fan panel. The
bumpers should be 1/2" from the panel to allow fan to free
float on the spring isolators.

General Lifting Considerations

WARNING
Risk of Unit Dropping!
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. Always place, assemble, and
suspend modules/subassemblies one at a time.
WARNING
Improper Unit Lift!
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. 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.

NOTICE
Equipment Damage!
Premature skid removal could result in 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.
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.
WARNING
Heavy Objects!
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. 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.
Always rig sub-assemblies 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
Table 16 and Table 9 for lug hole sizes and location.
