• 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.
To prevent possible SERIOUS INJURY OR DEATH:
• ALWAYS call a trained door systems technician if garage
door binds, sticks, or is out of balance. An unbalanced
garage door may not reverse when required.
• NEVER try to loosen, move or adjust garage door, door
springs, cables, pulleys, brackets or their hardware, all of
which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected to
garage door BEFORE installing and operating garage door
opener to avoid entanglement.
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and operating the
opener.
• ONLY operate garage door opener at 120V, 60 Hz to avoid

To reduce the risk of SEVERE INJURY or DEATH:
1. READ AND FOLLOW ALL INSTALLATION WARNINGS AND
INSTRUCTIONS.
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

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 inter secting 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.
• 8" (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 9 for ceiling 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.

• 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
