18. For sizes 3 through 120 hurricane units, attach roof
overhang angle with number 10 screws.
• For sizes 40 through 120 outdoor non-hurricane
outdoor units, a wide roof strip is provided. Apply
aluminum tape to block off open cavity beneath the
overhang angle and roof strip on both sides of unit
at the shipping split to prevent unwanted pests
from entering.
• For sizes 3 to 35 outdoor non hurricane units, slide
the C Channel between outdoor roofs at the splits.
19. On hurricane units, join outdoor roof panels together
at the seams in the direction perpendicular to airflow
and secure them in place with 5/16-inch x 3/4-inch bolts
and 5/16 lock nuts. Install the roof joint strip to cover the
seam between two outdoor roof panels perpendicular
to the direction of airflow. Use 3/8-inch butyl tape to
cover the seam between two outdoor roof panels
overhang at the side the unit. Bend joint strip over roof
panel and use two number 10 sheet metal screws (one
in each roof panel) to secure joint strip. Trim the roof
joint strip to insure that it does not protrude more than
1/16-inch beyond outdoor roof overhang (see
Figure 44).
