•Remove any ropes connected to garage door.
•Complete the following test to make sure your garage door is balanced and is not sticking or binding:
1.Lift the door about halfway as shown. Release the door. If balanced, it should stay in place, supported entirely by its springs.
2.Raise and lower the door to see if there is any binding or sticking.
If your door binds, sticks, or is out of balance, call a trained door systems technician.

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 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.
9.Install wall-mounted garage door control:

INSTALLATION STEP 1
Determine the Header Bracket
Location
WARNING
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.
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 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".)
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" above the high point. This height will provide travel clearance for the top edge of the door.
Proceed to Step 2, page 10.

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.
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
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.
HARDWARE SHOWN ACTUAL SIZE
Lag Screw 5/16"-9 x 1-5/8"
CEILING HEADER BRACKET INSTALLATION
•Extend the vertical centerline onto the ceiling as shown.
•Center the bracket on the vertical mark, no more than 6" from the wall. Make sure the arrow is pointing toward the wall. The bracket can be mounted flush against the ceiling when clearance is minimal.
•Mark the side holes. Drill 3/16" pilot holes and fasten bracket securely to a structural support with the hardware provided.
