ASSEMBLY STEP 1

Assemble the Rail

To avoid installation difficulties, do not run the garage door opener until instructed to do so.

1. Turn the opened rail carton upside down and empty its contents onto a level work surface.

2. Unfold the rails, taking care to avoid kinking the screw rod joint.

3. Rotate the rail sections so that the flat side is down and the screw side is up for all three lengths. Keep it clean and free of debris while you are working.

NOTE: During assembly, avoid pulling the rail section housing the trolley rack away from the screw rod. The rack is factory set about 9" (23 cm) from the end of the screw rod to the center of the rack.

If the plastic liner slides part way out during assembly, simply push it back in.

Assemble the Rail (Continued)

4. Beginning with the sprocket end, straighten the two rail sections so that the screw rod is in a straight line at the joint. (Avoid handling the joint, which may have sharp edges.)

5. Carefully slide the pins at the top edge of the rail into the openings on the adjacent rail. It is

essential that the rail assembly be on a level surface to achieve proper alignment and to avoid damage to the pins.

6. Insert two 1/4"-20x1-3/4" bolts through the center holes of a brace, and place its open length against the rail at the joint, aligning the holes as shown. Position another brace on the opposite side of the rail over the bolts, add 1/4"-20 lock nuts, and hand tighten. Insert two additional bolts and hand tighten.

7. Keeping the rail straight and on a level surface, grasp the screw rods on each side of the remaining joint and pivot into a straight line. Repeat steps 5 and 6.

8. With a 7/16" wrench, tighten bolts until snug, beginning with the center holes. Do not

overtighten.

INSTALLATION STEP 1

Determine the Header Bracket Location

Installation procedures vary according to garage door types. Follow the instructions which apply to your door.

1. Close the door and mark the inside vertical centerline of the garage door.

2. Extend the line onto the header wall above the door.

You can fasten the header bracket within 4 feet (1.22 m) of the left or right of the door center only if a torsion spring or center bearing plate is in the way; or you can attach it to the ceiling (see page 13) when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain approximately 1/2" (1 cm).

If you need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2x4 to structural supports as shown here and on page 13.

3. Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall above the high point:

• 3" (7.5 cm) above the high point for sectional door and one-piece door with track.

• 8" (20 cm) above the high point for one-piece door without track.

This height will provide travel clearance for the top edge of the door.

NOTE: If the total number of inches exceeds the height available in your garage, use the maximum height possible, or refer to page 13 for ceiling installation.

To prevent possible SERIOUS INJURY or DEATH:

• Header bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling, otherwise garage door might not reverse when required. DO NOT install header bracket over drywall.

• Concrete anchors MUST be used if mounting header bracket or 2x4 into masonry.

• NEVER try to loosen, move or adjust garage door, springs, cables, pulleys, brackets, or their hardware, all of which are under EXTREME tension.

• ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced garage door might not reverse when required.
