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.
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 lifting lugs.
The figures beginning with Figure 10, p. 30 show 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. lists
typical approximate minimal unit operating weights. To
determine additional component weight, see .
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.
Important: For replacements, remove old gasket from
the roof curb and place new gasket
material on curb. See “,” to determine
gasket material length using roof curb
dimensions.
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 below.
