9. Make sure all wiring and/or control tubing con-
nection pigtails are secured out of the path of the
shipping split mating surfaces to prevent damage.
10. Apply separate gasket squares (P/N 028-11883-
010) as shown in Figure 21 on page 30. Place
one square at each corner of the face of each sec-
tion.
11. Apply neoprene gasket (P/N 028-11883-010 or
P/N 028-11873-010) to face the perimeter from
square to square, and 1/4 in. from the outside
edge of the mating surface (nearest to AHU exte-
rior) to allow for a 1/4 in. bead of caulk. The gasket
application should provide a continuos seal from
side-to-side, and to the top of the AHU roof to the
bottom of the AHU base where it meets the curb.
12. Apply a 1/2 in. thick bead of caulk (not provided),
to the curb top surface only, where the first section
