Unit Rigging and Placement
1. To configure the unit Center-of-Gravity, utilize TOPSS
or contact the local Trane sales office.
2. Attach adequate strength lifting slings to all lifting lugs.The figures beginning with Figure20, p.51show the
minimum distance between the lifting hook and the
top
 of the unit and illustrate the installation of spreader
bars to protect the unit and to facilitate a uniform lift.
Table 12, p. 44lists typical approximate minimal unit
operating weights. To determine additional
component
 weight, see Table13, p. 44
3. Test lift the unit to ensure it is properly rigged and balanced,
 make any necessary rigging adjustments.
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.
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)
A cross section of the juncture between the unit and the roof curb is shown in Figure 19.
WARNING
Heavy Objects!
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. 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.

Air-Cooled and Evaporative Condensers—
Three-Piece Unit Fit Up
1. Rig and lift outside air section and evaporator section
separately.
2. Do not assemble unit on ground and attempt to lift toroof. Unit must be assembled on roof curb.
3. Attach rail guide provided to bottom of the evaporator base
 rails as shown with screws.
4. Rig and set the evaporator section onto the roof curb (aligned
 with supply end).
5. Remove and discard shipping protection panels and top
 block-offs from evaporator section.
6. Remove side panels and roof cap from evaporator section
 and set aside to be assembled later.
7. Apply gasket to the base channel and butyl tape to the base
 rail edge of the evaporator section. 8. Remove and discard shipping protection panels and
top
 block off from outside air section.
9. Rig and set outside air section onto roof curb using the rail
 guides as an alignment aid. Outside air section
must be within 2.0 from the evaporator section.
10. Use 0.75 x 24 threaded rod, nuts, washers and bac
 king plate provided to pull and secure sections
together.This must be done using the lifting lugs at the
unit split as shown.
11. Use 0.375 bolts, nuts and washers provided to pull and
 secure the roof rails together. This must be done
using the brackets on the roof rails as shown.
12. Attach roof splice plate to bottom side of roof panels at the
 unit split with ¼ sheet metal screws.
13. Add bullwrap to electrical wiring.
14. Connect power and control wiring at the unit split. Place
 power wiring connectors inside junction box.

15. Apply gasket to side panels removed earlier. Attach
side panel to unit split.
16. Apply 1.25 butyl tape on top of unit split along the roof seam.
17. Attach roof cap over roof seam and butyl tape with screws

Air-Cooled and Evaporative Condensers—
Two-Piece Unit Fit Up
1. Rig the low side unit (Air handler) and the high side unit
(Condenser) separately.
2. First, rig and set the low side unit on the roof curb (aligned with return end). 3. Take off and discard the protection boxes. (Do not
remo
 ve wire shields).
4. Remove the rail connector splice brackets and install the
 brackets on the low side unit base rails.
5. Take off the side panels (these are labeled) and the top co
 ver of the high side unit and set aside to be
assembled later.
6. Rig and set the high side unit on roof curb pedestal, using
 the rail splice bracket as an alignment aid to
connect the Low and high side units.The Low and high
side unit rails should be butted together with a
maximum 2 separation.
7. Remove the left upper and lower louvered panels and the
 corner panels on each side to aid in tubing and
wiring connections.
