1 Determine the Header Bracket Location
To prevent possible SERIOUS INJURY or DEATH: l l
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.
l l l
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.
DO NOT enable the Timer-to-Close functionality if operating either one-piece or swinging garage doors. To be enabled ONLY when operating a sectional door.
NOTE: If you are installing the garage door opener on a one-piece door, visit www.liftmaster.com for installation instructions.
Close the door and mark the inside vertical centerline of the garage door.
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 securely fasten the 2x4 to structural supports.
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.
NOTE: If the total number of inches exceeds the height available in your garage, use the maximum
height possible, or refer to page 6 for ceiling installation.

5 Hang the Garage Door Opener
To avoid possible SERIOUS INJURY from a falling garage door opener, fasten it SECURELY to structural supports of the garage. Concrete anchors MUST be used if installing ANY brackets into masonry.
Hanging your garage door opener will vary depending on your garage. Two representative installations are shown. Yours may be different. Hanging brackets should be angled (Figure 1) to provide rigid support. On finished ceilings (Figure 2), attach a sturdy metal bracket to structural supports before installing the opener. This bracket and fastening hardware are not provided.
1. Measure the distance from each side of the motor unit to the structural support.
2. Cut both pieces of the hanging bracket to required lengths.
3. Drill 3/16" pilot holes in the structural supports.
4. Attach one end of each bracket to a support with 5/16"-18x1-7/8" lag screws (not provided).
5. Fasten the opener to the hanging brackets with 5/16"-18x7/8" hex bolts, lock washers and nuts.
6. Check to make sure the rail is centered over the door (or in line with the header bracket if the brackest is not centered above the door).
7. Remove the 2x4. Operate the door manually. If the door hits the rail, raise the header bracket.
NOTE: DO NOT connect power to opener at this time.

8 Install the Door Bracket
Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE reinforcement BEFORE installation of door bracket. Contact the garage door manufacturer or installing dealer for opener reinforcement instructions or reinforcement kit. Failure to reinforce the top section as required according to the door manufacturer may void the door warranty.
A horizontal and vertical reinforcement is needed for lightweight garage doors (fiberglass, aluminum, steel, doors with glass panel, etc.) (not provided). A horizontal reinforcement brace should be long enough to be secured to two or three vertical supports. A vertical reinforcement brace should cover the height of the top panel. Contact the garage door manufacturer or installing dealer for opener reinforcement instructions or 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.
SECTIONAL DOORS
1. Center the door bracket on the previously marked vertical centerline used for the header bracket installation. Note correct UP placement, as stamped inside the bracket.
2. Position the top edge of the bracket 2"-4" (5-10 cm) below the top edge of the door, OR directly below any structural support across the top of the door.
3. Mark, drill holes and install as follows, depending on your door’s construction:
Metal or light weight doors using a vertical angle iron brace between the door panel support and the door bracket:
l
Drill 3/16" fastening holes. Secure the door bracket using the two self threading screws.
l
(Figure 1)
Alternately, use two 5/16" bolts, lock washers and nuts (not provided). (Figure 2)
Metal, insulated or light weight factory reinforced doors:
l
Drill 3/16" fastening holes. Secure the door bracket using the self-threading screws. (Figure 3)
Wood Doors:
