Planning
Identify the type and height of your garage door. Survey your garage area to see if any of the conditions below apply to your installation. Additional materials may be required. You may fi nd it helpful to refer back to this page and the accompanying illustrations as you proceed with the installation of your opener.
Depending on your requirements, there are several installation steps which may call for materials or hardware not included in the carton.
• Installation Step 1 – Look at the wall or ceiling above the garage door. The header bracket must be securely fastened to structural supports.
• Installation Step 5 – Do you have a fi nished ceiling in your garage? If so, a support bracket and additional fastening hardware may be required.
• Installation Step 11 – Depending upon garage construction, extension brackets or wood blocks may be needed to install sensors.
• Installation Step 11 – Alternate fl oor mounting of the safety reversing sensor will require hardware not provided.
SECTIONAL DOOR INSTALLATION
Horizontal and vertical reinforcement is needed for lightweight garage doors (fi berglass, steel, aluminum, door with glass panels, etc.). See page 25 for details.
Header Wall
• Do you have an access door in addition to the garage door? If not, Model 7702CB Emergency Key Release is required. See Accessories page.
• Look at the garage door where it meets the fl oor. Any gap between the fl oor and the bottom of the door must not exceed 1/4" (6 mm). Otherwise, the safety reversal system may not work properly. See Adjustment Step 3. Floor or door should be repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fi berglass or glass panel door? If so, horizontal and vertical reinforce ment is required (Installation Step 12).
• The opener should be installed above the center of the door. If there is a torsion spring or center bearing plate in the way of the header bracket, it may be installed within 4 feet (1.2 m) to the left or right of the door center. See Installation Steps 1 and 12.

ASSEMBLY STEP 1
Assemble the Rail and Install the Trolley
To avoid installation diffi culties, do not run the garage door opener until instructed to do so.
The front rail has a cut out “window” at the door end (see illustration). The hole above this window is larger on the top of the rail than on the bottom. A smaller hole 3-1/2" (8.9 cm) away is close to the rail edge. Rotate the back rail so it has a similar hole close to the opposite edge, about 4-3/4" (12 cm) from the far end.
1. Remove the straight door arm and hanging bracket packaged inside the front rail and set aside for Installation Step 5 and 12. 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 fl at surface as shown and
slide the tapered ends into the larger ones. Tabs along the side will lock into place.
To prevent INJURY from pinching, keep hands and fi ngers away from the joints while assembling the rail.
3. Place the motor unit on packing material to protect the cover, and rest the back end of the rail on top. For convenience, put a support under the front end of the rail.
4. As a temporary stop, insert a screwdriver into the hole 10" (25 cm) from the front end of the rail, as shown.
5. Check to be sure there are 4 plastic wear 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 assembly along the rail from the back end to the screwdriver.

INSTALLATION STEP 1
Determine the Header Bracket Location
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.
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 inter secting horizontal line on the header wall 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.
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.
