Installation
Lifting and Rigging
WARNING Lifting and Rigging!
Do not lift, rig, or
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.
Do not use a fork lift for handling units. This may result in equipment damage. Trane is not responsible for equipment damage resulting from improper forklifting practices.
Figure 3. Use proper lifting and rigging methods
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.
Always place, assemble, and suspend sections one at a time.
Failure to follow instructions could result in death or serious injury or equipment damage.
Figure 2. Recommended attachment to lifting lugs.
Per job requirements, air handlers will ship as a complete assembly or in sections.
Trane recommends that the contractor use spreader bars and slings to rig units and subassemblies.
Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety. Because of the placement of internal components, the unit weight may be unevenly distributed, with more weight in the coil and fan areas. Refer to the unit submittals for section weights. Test the unit for proper balance and rigging before lifting.
General Lifting
Considerations
•Always rig subassemblies or sections as they ship from the factory. See the unit submittal drawings for correct placement of sections.
•Always assemble unit at the installation site. Never bolt sections together before rigging.
•Make the loop of the sling parallel to the direction of airflow, if possible.
•Each of the cables used to lift the unit must be capable of supporting the entire weight of the unit.
•When hoisting the unit into position, use the proper rigging method, such as straps, slings, spreader bars, or lifting lugs for protection and safety.
Note: Never lift units in windy conditions.
