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).

2.Install garage door opener ONLY on properly balanced and lubricated garage door. An improperly balanced door may not reverse when required and could result in SEVERE

INJURY or DEATH.

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 (2.13 m) or more above floor.

6.Mount emergency release handle 6 feet (1.83 m) 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.

9.Install wall-mounted garage door control:

within sight of the garage door.

out of reach of children at minimum height of 5 feet (1.5 m).

away from ALL moving parts of the door.

10.Place entrapment warning label on wall next to garage door control.

11.Place manual release/safety reverse test label in plain view on inside of garage door.

12.Upon completion of installation, test safety reversal system. Door MUST reverse on contact with a 1-1/2" (3.8 cm) high object (or a 2x4 laid flat) on the floor.

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 9) 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 9.

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.

Follow instructions which apply to your door type as illustrated.

SECTIONAL DOOR OR ONE-PIECE DOOR WITH TRACK

A 2x4 laid flat is convenient for setting an ideal door-to-rail distance.

Remove foam packaging.

Raise the opener onto a stepladder. You will need help at this point if the ladder is not tall enough.

Open the door all the way and place a 2x4 laid flat on the top section beneath the rail.

If the top section or panel hits the trolley when you raise the door, pull down on the trolley release arm to disconnect inner and outer sections. Slide the outer trolley toward the motor unit. The trolley can remain disconnected until Installation Step 12 is completed.

To prevent damage to garage door, rest garage door opener rail on 2x4 placed on top section of door.
