Installation
STEP 1 Determine the Header Bracket Location
To prevent possible SERIOUS INJURY or DEATH:
lHeader 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.
lConcrete anchors MUST be used if mounting header bracket or 2x4 into masonry.
lNEVER try to loosen, move or adjust garage door, springs, cables, pulleys, brackets, or their hardware, ALL
of which are under EXTREME tension.
lALWAYS 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 12) 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 12.
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:
l2" (5 cm) above the high point for sectional door and one-piece door with track.
l8" (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 12 for ceiling installation.

INTRODUCTION
Older Chamberlain door controls and third party products are not compatible. Install door control within sight of
garage door, out of reach of small children at a minimum height of 5 feet (1.5 m) above floors, landings, steps or any
other adjacent walking surface, and away from ALL moving parts of door. For gang box installations it is not
necessary to drill holes or install the drywall anchors. Use the existing holes in the gang box.

2. Connect one wire to each of the two screws on the back of the door control. The wires can be connected to
either screw. If your garage is pre-wired for the door control choose any two wires to connect, note which
wires are used so the correct wires are connected to the garage door opener in a later step.
3. Mark the location of the bottom mounting hole and drill a 5/32" hole.
4. Install the bottom screw, allowing 1/8" (3 mm) to protrude from the wall.
5. Position the bottom hole of the door control over the screw and slide down into place.
