Mounting Opener to Ceiling
To prevent SERIOUS INJURY or DEATH:
- DO NOT connect power until instructed.
- Install the Opener at least 7 feet (2.13m) above the floor.
- Fasten the Opener SECURELY to STRUCTURAL SUPPORTS of the garage to prevent falling.
- If installing Brackets to masonry, concrete anchors (not provided) MUST be used.
To Mount the Opener to Ceiling
The three most common installation options are shown below:
(i)
Mounting the Opener directly to structural support on the
ceiling.
(ii)
Mounting on a finished ceiling, with heavy duty angle iron.
(iii)
Alternative mounting on a finished ceiling, with heavy duty
angle iron.
*Note: angle iron not included.
Determine the mounting option that works best
for your application and follow installation steps
below:
1. Raise the Opener and rail assembly and temporarily place it
on a stepladder.
2. Position the Opener and rail assembly so that it is aligned to
the center line of the garage door. If the Header Bracket was
mounted off center, align the Opener with the Header
Bracket.
3. Measure the distance from each side of the Opener to the
structural supports.
4. Cut both Hanging Brackets* to appropriate length.
*(Hanging Bracket not included)
5. Drill 3/16” holes in the structural supports.
6. Secure one end of each of the Hanging Brackets to the
structural supports using 5/16” x1-5/8” Lag Screws (provided).
7. Secure the Opener to the Hanging Brackets and secure each
side with a 5/16”-18x1” Bolt and Flange Nut (provided).
8. Move the door manually to check clearance between
highest point of travel of the door and rail. If the door hits the
rail, raise the Header Bracket or adjust the mounting of
Opener.
9. Remove the ladder ONLY when the Opener is securely
mounted to the structural supports.
