If your door binds, sticks, or is out of balance, call a trained door systems technician.

To prevent damage to garage door and opener:

• ALWAYS disable locks BEFORE installing and operating the opener.

• ONLY operate garage door opener at 120V, 60 Hz to avoid malfunction and damage.

To prevent possible SERIOUS INJURY OR DEATH:

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

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

• Disable ALL locks and remove ALL ropes connected to garage door BEFORE installing and operating garage door opener to avoid entanglement.

ASSEMBLY STEP 1

Attach the Rail to the Motor Unit

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

• Remove the two washered bolts mounted in top of motor unit.

• Align rail and styrofoam over sprocket. Cut tape from rail, belt and styrofoam.

• REMOVE STYROFOAM.

• Insert both washered bolts through the rail into the motor unit. Tighten bolts securely.

Use only these bolts! Use of any other bolts will cause serious damage to door opener.

• Position belt over the motor unit sprocket.

ASSEMBLY STEP 2

Set the Belt Tension

• By hand, thread the spring trolley nut on the

threaded shaft until it is finger tight against the trolley (Figure 1). Do not use any tools.

• Insert a screwdriver tip into one of the nut ring slots

and brace it firmly against the trolley (Figure 2).

• Place a 7/16" open end wrench on the square

end. Rotate about 1/4 turn until the spring releases and snaps the nut ring against the trolley (Figure 3).

This extends the spring for optimum belt tension.

3. All repairs to cables, spring assemblies and other hardware MUST be made by a trained door systems technician BEFORE installing opener.

4. Disable all locks and remove all ropes connected to garage door BEFORE installing opener to avoid entanglement.

5. Install garage door opener 7 feet or more above floor.

6. Mount emergency release handle 6 feet above floor.

7. NEVER connect garage door opener to power source until instructed to do so.

8. NEVER wear watches, rings or loose clothing while installing or servicing opener. They could be caught in garage door or opener mechanisms.

INSTALLATION STEP 1

Determine the Header Bracket Location

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

SECTIONAL DOOR AND ONE-PIECE DOOR WITH TRACK

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 (1.2 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 10) when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain approximately 1/2" [1.25 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 10.

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

Proceed to Step 2, page 10.

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.

ONE-PIECE DOOR WITHOUT TRACK

1. Close the door and mark the inside vertical centerline of your garage door. Extend the line onto the header wall above door, as shown.

If headroom clearance is minimal, you can install the header bracket on the ceiling. See page 10.

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

2. Open your door to the highest point of travel as shown. Measure the distance from the top of the door to the floor. Subtract the actual height of the door. Add 8" to the remainder. (See Example).

3. Close the door and draw an intersecting horizontal line on the header wall at the determined height.

NOTE: If the total number of inches exceeds the height available in your garage, use the maximum height possible, or refer to page 10 for ceiling installation.

INSTALLATION STEP 2

Install the Header Bracket

You can attach the header bracket either to the wall above the garage door, or to the ceiling. Follow the instructions which will work best for your particular requirements. Do not install the header bracket

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

WALL HEADER BRACKET INSTALLATION

• Center the bracket on the vertical centerline with

the bottom edge of the bracket on the horizontal line as shown (with the arrow pointing toward the ceiling).

• Mark the vertical set of bracket holes (do not use

the holes designated for ceiling mount). Drill 3/16" pilot holes and fasten the bracket securely to a structural support with the hardware provided.
