were not assembled before placing the AHU on
the curb, complete the following steps:
1. Use the construction grade caulk (not pro-
vided) in place of the curb top gasket and the
following instructions to apply it.
2. Apply the caulk on top of curb before each
section is placed on the curb.
3. Apply the caulk with a 1/2 in. diameter bead
to make sure the seal is sealed after sections
are pulled together.
3. If the AHU sections are going to be assembed be-
fore placing them on a curb, be sure the they are
lying on a at surface during assembly.
4. Make sure the top of curb is at, and shims were
added, if needed, to ensure the curb remains at.
5. Verify the correct sections, and orientation of each
one.
6. Remove the cross brace(s) (shipping supports)
from each section’s shipping split.
7. Remove the plastic shipping covers and supports.
