Rotatethe back rail so it has a similar hole close to the opposite edge, about 4-3/4" (12 cm) from the far end.

1. Removethe straight door arm and hanging bracketpackaged inside the front rail and set aside for Installation Step 5 and 9. NOTE: To prevent INJURY while unpacking the rail

carefully remove the straight door arm stored within the rail section.

2. Align the rail sections on a flat surface as shown and slide the tapered ends into the larger ones. Tabs along the side will lockinto place.

3. Place the motor unit on packing material to protectthe cover,and rest the backend of the rail on top. For convenience, put a support under the front end of the rail.

4. As a temporary stop, inserta screwdriver into the hole 10" (25 cm) from the frontend of the rail, as shown.

5. Checkto be sure there are 4 plasticwear pads inside the inner trolley. If they became loose during shipping, check all packing material. Snap them back into position as shown.

6. Slide the trolley assemblytoward the screwdriveras shown.

STEP 1 Determine the header bracket location

To prevent possible SERIOUSINJURY 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 bracketover drywall.

• Concreteanchors MUST be used if mounting header bracketor 2x4 into masonry.

• NEVER tryto loosen, move or adjustgarage 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.

Installation procedures vary according to garage door types.Follow the instructionswhich 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 within4 feet (1.22 m) of the left or right of the door center only if a torsionspring or center bearingplate is in the way; or you can attach it to the ceiling when clearance is minimal.(It may be mountedon the wall upside down if necessary, to gain approximately 1/2" (1 cm).

Ifyou need to install the header bracketon a 2x4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2x4 to structural supports.

3. Open your door to the highest point of travel as shown.Draw an intersecting horizontal line on the header wall 2" (5 cm) above the high point :

2" (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.

Thisheight 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 12 for ceiling installation.

drywall. If installing into masonry, use concrete anchors (not provided).

OPTION A WALL INSTALLATION

1. Centerthe bracket on the verticalcenterline with the bottomedge of the bracket on the horizontal line as shown.

2. Mark the vertical set of bracketholes. Drill 3/16" pilot holes and fasten the bracketsecurely to a structural support with the hardware provided.

OPTION B CEILING INSTALLATION

1. Extend the vertical centerline onto the ceiling as shown.

2. Center the bracketon the vertical mark, no more than 6" (15 cm) from the wall. Make sure the arrow is pointing away fromthe wall. The bracketcan be mounted flush against the ceiling when clearance is minimal.

3. Mark the side holes.Drill 3/16" pilot holes and fasten bracketsecurely to a structural support withthe hardware provided.
