8) Figure 12 details a typical method of hanging the operator
from the ceiling. Each installation will vary due to the
difference in building structures; but in all installations side
braces should be used to further strengthen the installation. If
the operator track (rail) is longer than 15 feet a mid support is
recommended.
9) Fully close the door and move the trolley to within 2
inches of the idler sprocket. Using Figure 13 as a guide,
connect the release arm (Item 19) to the trolley. Connect the
two extension arms (Item 20) and the door curved arm (Item 21)
to the door release arm with 5/16 inch bolts and keps nuts
(Items 28 & 29).
10) Refer to Figure 14. Attach the door bracket (Item 22) to
the curved arm using a 3/8 bolt and locknut (Items 16 & 27).
Tighten the bolt until snug then back off 1/4 to 1/2 turns so as to
allow the arm to pivot on the bolt freely. Position the door
bracket to the scribed center line on the door. Use suitable
hardware to attach the door bracket to the door.
