MOUNTING THE OPENER:

1.Getting started.

•Position assembled rail on wall next to header bracket (Fig. 2-4).

–Place material on floor under power head to protect from scratching. (A box, stool, or similar device may be needed to clear a torsion spring.)

NOTE: For header bracket pins locate Bag 2 from Box 1.

2.Mounting the assembly.

•Attach rail to header bracket using clevis pin and cotter pin (Fig. 2-5).

•Support power head on step-ladder to prevent interference with header mounted (torsion) spring.

NOTE: Before final attachment to ceiling, insure that assembly is in proper alignment (Fig. 2-4).

NOTE: For nuts, bolts, and lag screws locate Bag 3 from Box 1.

•On finished ceilings, locate ceiling joists or trusses using a stud finder or similar device. Attach angle iron (not provided) to joists or trusses through finish material using (provided) lag screws (Fig. 2-6).

•On unfinished ceilings or open ceilings, straps may attach directly to joists or trusses. Depending on the garage construction, extra framing material (not provided) which may be required should be installed using appropriate construction techniques (Fig. 2-6).

NOTE: Refer to your local building codes for appropriate framing materials and construction techniques.

•Attach mounting straps (not provided) to ceiling using lag bolts (Fig. 2-6).

•Set height of power head to following (Fig. 2-6).

a)Rail must clear door at door’s highest point of travel.

b)Be level or power head slightly below level.
