Planning
Identify the type and height of your garage door. Survey
your garage area to see if any of the conditions below
apply to your installation. Additional materials may be
required. You may fi nd it helpful to refer back to this page
and the accompanying illustrations as you proceed with
the installation of your opener.
Depending on your requirements, there are several
installation steps which may call for materials or hardware
not included in the carton.
• Installation Step 1 – Look at the wall or ceiling above
the garage door. The header bracket must be securely
fastened to structural supports.
• Installation Step 5 – Do you have a fi nished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
• Installation Step 10 – Depending upon garage
construction, extension brackets or wood blocks may
be needed to install sensors.
• Installation Step 10 – Alternate fl oor mounting of
the safety reversing sensor will require hardware not
provided.
SECTIONAL DOOR INSTALLATION
Horizontal and vertical reinforcement
is needed for lightweight garage
doors (fi berglass, steel, aluminum,
door with glass panels, etc.).
See page 24 for details.
• Do you have an access door in addition to the garage
door? If not, Model 7702CB Emergency Key Release is
required. See Accessories page.
• Look at the garage door where it meets the fl oor. Any
gap between the fl oor and the bottom of the door must
not exceed 1/4" (6 mm). Otherwise, the safety reversal
system may not work properly. See Adjustment Step 3.
Floor or door should be repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fi berglass or glass
panel door? If so, horizontal and vertical reinforce ment
is required (Installation Step 11).
• The opener should be installed above the center of the
door. If there is a torsion spring or center bearing plate
in the way of the header bracket, it may be installed
within 4 feet (1.2 m) to the left or right of the door
center. See Installation Steps 1 and 11.
• If your door is more than 7 feet (2.1 m) high, see rail
extension kits listed on Accessories page.

slide the tapered ends into the larger ones. Tabs along
the side will lock into place.
To prevent INJURY from pinching, keep hands and
fi ngers away from the joints while assembling the rail.
3. Place the motor unit on packing material to protect
the cover, and rest the back end of the rail on top.
For convenience, put a support under the front end of
the rail.
4. As a temporary stop, insert a screwdriver into the hole
10" (25 cm) from the front end of the rail, as shown.
5. Check to be sure there are 4 plastic wear pads inside
the inner trolley. If they became loose during shipping,
check all packing material. Snap them back into
position as shown.
6. Slide the trolley assembly along the rail from the back
end to the screwdriver.

INSTALLATION STEP 1
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 13) 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 13.
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 13 for ceiling installation.
