d. For certain high pressure low leakage units,
use the provided section joining plates to fasten
sections together. Space them as shown in Figure
9 . Using the provided ¼"-14 × 1" self tapping
screws, drill screw the joining plates into the frame
channel on each section, keeping unit sections
tight together. Follow instruction drawing included
in the assembly kit.
4. After sections are seated tightly together, add caulk
to the external section split joint from top to bottom.
DO NOT caulk the bottom of the base rail at the section
split. This seam acts as a weep hole.
5. After sections are seated tightly together, add caulk to fill
the seam between the roof panels at each end. Slide the
splice cap over the top panel flanges. Bend the ends of
the splice cap down to secure in place ( Figure 12 )
6. Assemble the small splice plate at the top rail to secure
the sections together at the top. Use 5/16" bolts ( Figure
12 ).
