SECTIONAL DOOR INSTALLATION

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 find 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 finished ceiling in your garage? If so, a support bracket and additional fastening hardware may be required.

• Installation Step 10 – Depending upon garage construction, extension brackets or wood blocks may be needed to install sensors.

• Installation Step 10 – Alternate floor mounting of the safety reversing sensor will require hardware not provided.

• 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 floor. Any gap between the floor 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, fiberglass or glass panel door? If so, horizontal and vertical reinforcement is required (Installation Step 11).

• 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 (1.22 m) to the left or right of the door center. See Installation Steps 1 and 11.

• If your door is more than 7 feet (2.13 m) high, see rail extension kits listed on Accessories page.

Horizontal and vertical reinforcement is needed for lightweight garage doors (fiberglass, steel, aluminum, door with glass panels, etc.). See page 23 for details.

ASSEMBLY STEP 1

Assemble the Rail & Install the Trolley

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

To prevent INJURY from pinching, keep hands and fingers away from the joints while assembling the rail.

WARNING

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 flat surface as shown and slide the tapered ends into the larger ones. Tabs along the side will lock into place.

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.

ASSEMBLY STEP 2

Fasten the Rail to the Motor Unit

• Insert a 1/4"-20x1-3/4 bolt into the cover protection bolt hole on the back end of the rail as shown. Tighten securely with a 1/4"-20 lock nut. Do NOT

overtighten.

• Remove the two bolts from the top of the motor unit.

• Place the “U” bracket, flat side down, on the motor unit and align the bracket holes with the bolt holes. Fasten with the previously removed bolts.

• Align the rail assembly with the top of the motor unit. Slide the rail end onto the “U” bracket, all the

way to the stops that protrude on the top and sides of the bracket.

ASSEMBLY STEP 3

Install the Idler Pulley

• Lay the belt beside the rail, as shown. Grasp the end with the hooked trolley connector and pass approximately 12" (30 cm) of belt through the window. Keep the ribbed side toward the rail, and allow it to hang until Assembly Step 5.

• Remove the tape from the idler pulley. The inside center should be pre-greased. If dry, regrease to ensure proper operation.

• Place the idler pulley into the window as shown.

• Insert the idler bolt from the top through the rail and pulley. Tighten with a 3/8" lock washer and nut underneath the rail until the lock washer is compressed.

• Rotate the pulley to be sure it spins freely.

• Insert a 1/4"-20x1-3/4 bolt into the trolley stop hole in the front of the rail as shown. Tighten securely with a 1/4"-20 lock nut.

WARNING

CAUTION

ASSEMBLY STEP 4

Install the Belt and Attach the Belt Cap Retainer

1. Pull the belt around the idler pulley and toward

the trolley. The ribbed side must contact the

pulley.

2. Hook the trolley connector into the retaining slot

on the trolley as shown.

3. With the trolley against the screwdriver, dispense

the remainder of the belt along the rail length toward the motor unit and around the sprocket. The sprocket teeth must engage the belt.

4. Check to make sure the belt is not twisted, then

connect it to the flat end of the trolley threaded shaft with the master link, as illustrated:

• Push pins of master link bar through holes in end of belt and trolley threaded shaft.

• Push master link cap over pins and past pin notches.

• Slide clip-on spring over cap and onto pin notches until both pins are securely locked in place.

5. Insert the trolley threaded shaft through the hole

in the trolley. Be sure the belt is not twisted, and

the ribbed side faces the rail.

6. Hold the belt at the trolley shaft as you thread the spring nut by hand onto the shaft until finger tight against the trolley. Do not use any tools.

7. Remove the screwdriver.

8. Position the belt cap retainer over the motor unit sprocket as shown and fasten to the mounting plate with 8x3/8" hex screws provided.

To avoid possible SERIOUS INJURY to fingers from moving garage door opener:

• ALWAYS keep hand clear of sprocket while operating opener.

• Securely attach sprocket cover BEFORE operating.

WARNING

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:

• 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.

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.
