3. Fasten angle irons (if span is longer than 8 ft)

ATTENTION

If the angle iron span is 8 ft (2.4 m) or less, proceed to step 4a on the following page.

If the angle iron span is greater than 8 ft (2.4 m), it is necessary to use double angle irons (total of four).

Locate the center of the angle iron length. Drill a ø9/16” (1.4 cm) hole through the centers of the vertical walls of

four angle irons. Place two drilled angle irons back-to-back. Fasten the angle irons together with installer-supplied

Grade 8 hardware. Align the angle irons to each other and tighten the bolts to 40 ft·lb (54.2 N·m).

Repeat this step for the remaining two angle irons.

Installer-Supplied Grade 8 Hardware:

a. (2) 1/2-13 Bolt

b. (4) 1/2” Flat Washer

c. (2) 1/2” Nut

2. Pre-drill angle irons

Drill two ø9/16” (1.4 cm) holes exactly 5-3/8” (13.7 cm) apart in the centers of two angle irons. If the motor frame will

be mounted directly to the angle irons, drill two ø9/16” (1.4 cm) holes exactly 5-1/2” (14 cm) apart in the centers of

two angle irons.

Measure the distance between the mounting points of the roof structure that the angle irons will span. Measure

the same distance on the angle irons, and then drill two ø9/16” (1.4 cm) holes through the ends of the angle irons.

If the span is 8 ft (2.4 m) or less, drill holes in the two angle irons. If the span is greater than 8 ft (2.4 m), drill holes

in four angle irons.
