Unit Rigging and Placement

WARNING
Heavy Object!
Failure to follow instructions below could result in
unit dropping 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 unit lift.
Note: Use spreader bars as shown in the diagram. Refer to
"Weights," p. 27 or the unit nameplate for the unit
weight. Refer to the Installation Instructions located
inside the side control panel for further rigging
information.
1. To configure the unit Center-of-Gravity, utilize Trane
Select Assist or contact the local Trane sales office.
2. Attach adequate strength lifting slings to all four lifting
lugs on 20-30 ton units and all six lifting lugs on the 40-
130 ton units. The minimum distance between the
lifting hook and the top of the unit should be 7 feet for

4. Lift the unit and position it over the curb and pedestal.
These units have a continuous base rail around the air
handler section which matches the curb.
Important: For replacements, remove old gasket from
5. Align the base rail of the unit air handler section 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. (The pedestal simply supports the
unit condenser section)
