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 Figure 23, p. 48
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.
IImmppoorrttaanntt:: For replacements, remove old gasket
from the roof curb and place new
gasket material on curb. See ā,ā 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.
