Vertical Inverted Airflow Section
Mounting
For vertical or inverted arrangements, before lifting any top
mounting sections into place, rig into place and fasten together
the bottom tier of sections . Once bottom level sections are in
place and secured, lift stacked components and fasten using
the following procedure:
NOTE: See Face and Bypass Section Mounting on page
14 for the exception to this procedure .
1 . The vertical/inverted section has a splice joint extending
out the top of the bottom joining section. Lower the
section that is to be positioned over the opening over
the splice joint to seal the connection between the two
sections .
2 . The two sections are fastened together at the four
bottom corners of the mating edge . To fasten the corners
located on the end of the unit (where bottom section and
top section walls are flush with each other), remove the
flat head fasteners in the corners of both sections.
3 . Cover the coned holes with a flat joining plate and
replace the flat head fasteners in the holes to secure the
joining plate to both sections
4 . When one section is deeper than the other, secure the
two sections using an L-shaped joining plate. To secure
the L-shaped bracket, remove the flat head fastener
from the corner, position the bracket over the hole, and
replace the flathead fastener with a 5/16"-18 × 1" bolt.
Once the bolt is in place, secure the bracket to the
adjoining section with a 1/4" × 1" drill screw. Repeat the
same procedure on both corners of the unit
