VERTICAL

HORIZONTAL CENTERLINE LINE

STEP 1: Mounting the Front Bracket: Mark a vertical centerline on the header above the door. By manually raising the door, determine the high arc of the door’s travel (see illustration, top of previous page) and using a level, transfer this measurement to the header (see illustration at left). Draw a horizontal line, crossing the previously drawn centerline, at this point. Install the Front Mounting Bracket securely wit lag screws as shown below. If necessary, reinforce the header with steel angle iron or wood to ensure a secure mount.

STEP 3 — Raise the Opener and rest the Power Unit on a ladder or other sturdy support. Open the door the full open position. Allow 2" of space between the Tee Rail and the top section of the door (as shown in the illustration, below on the right).

NOTE: Since the Opener will be secured permanently in this position, open and close the door a few times to be sure the door does not rub on the Tee Rail and that you have allowed the proper clearances before proceeding.
