Installation

1 Determine the header bracket

location

To preventpossible SERIOUS INJURY or

DEATH:

• Header bracketMUSTbe RIGIDLY

fastened to structural supporton header

wall or ceiling, otherwise garage door might

NOTreverse when required. DO NOT

install header bracket over drywall.

• Concrete anchors MUSTbe used if

mounting header bracketor 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

Installation procedures varyaccording to garage door types. Follow the instructionswhich applyto your

door.

1.1 Close the door and mark the inside vertical centerline ofthe garage door.

1.2 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 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 securelyfasten the 2x4 to structural supports.

1.3 Open your door to the highestpoint oftravel as shown. Draw an intersecting horizontal line on

the header wall 2" (5 cm) above the high point.

• 2" (5 cm) above the high pointfor sectional door and one-piece door with track.

• 8" (20 cm) above the high point for one-piece door withouttrack.This heightwill 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.

5 Hang the garage door opener

To preventpossible OVERHEAT NG of the end panel or lightsocket:

• Use ONLY A19 incandescent or compact fluorescent lightbulbs.

• DO NOT use incandescent bulbs larger than 100W.

• DO NOT use compact fluorescent lightbulbs larger than 26W (100W) equivalent.

• DO NOT use halogen bulbs.

• DO NOT use short neck or specialty light bulbs.

6.1 Pull on the top sides ofthe light lens and

rotate the light lens down.

6.2 Insert an A19 incandescent or compact

fluorescentlight bulb (100 watt maximum),

into the lightsocket.

6.3 Rotate the lensup to close.

NOTE: The use of short neck or speciality light

bulbs may overheat the end panel or light socket.

7 Attach the emergency release rope and handle

To preventpossible SERIOUS INJURY or DEATH from a falling garage door:

• If possible, use emergency release handle to disengage trolley ONLY when garage door is

CLOSED. Weak or broken springs or unbalanced door could result in an open door falling

rapidly and/or unexpectedly.

• NEVER use emergency release handle unless garage doorwayis clear of persons and

obstructions.

• NEVER use handle to pull door open or closed.Ifrope knotbecomesuntied,you could fall.

7.1 Insert one end of the emergency release

rope through the handle. Make sure that

“NOTICE” is right side up. Tie a knot at

least 1 inch (2.5 cm) from the end of the

emergency release rope.

7.2 Insert the other end of the emergency

release rope through the hole in the

trolley release arm. Make sure the

handle is 6 feet (1.83 m) above the floor

and secure with a knot.

NOTE: If it is necessary to cut the emergency

release rope, seal the cut end with a match or

lighter to prevent unraveling. Ensure the

emergency release rope and handle are

above the top of all vehicles to avoid

entanglement.

Installation

6 Install the light bulbs

Fiberglass,aluminum or lightweightsteel garage doors WILLREQUIRE reinforcement BEFORE

installation of door bracket.Contactyour door manufacturer for reinforcement kit.

Figure 1 showsone piece of angle iron as the horizontal brace.

For the vertical brace, 2 pieces of angle iron are used to create a

U-shaped support. The best solution is to check with your garage

door manufacturer for an opener installation door reinforcement

kit.

NOTE: Many door reinforcement kits provide for direct attachment

of the clevis pin and door arm. In this case you will not need the

door bracket; proceed to the next step.
