• 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.
If you have a one-piece door, the installation of your
garage door opener will be different. Follow the assembly
instructions included in this manual then proceed to the
Installation Instructions For One-Piece Doors included with
the garage door opener.

PLANNING
Identify the type and height of your garage door. If you
have a one-piece door, follow the assembly
instructions contained in this manual and refer to the
Installation Instructions One-Piece Door for
installation procedures. Survey your garage area to see
if any of the conditions below apply to your installation.
Additional materials may be required. You may find 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 Page 10 – Look at the wall or ceiling above
the garage door. The header bracket must be securely
fastened to structural supports.
•Installation Page 12 – Do you have a finished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
•Installation Page 13 – Do you have a steel, aluminum,
fiberglass or glass panel door? If so, horizontal and
vertical reinforcement is required.
•Installation Page 18 – Depending upon garage
construction, extension brackets or wood blocks may be
needed to install sensors.
•Installation Page 18 – Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.
• Do you have an access door in addition to the garage
door? If not, Model 7702CB Outside Quick Release is
required. See Accessories page.
• Look at the garage door where it meets the floor. Any
gap between the floor 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.
• 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 (1.22 m) to the left or right of the door
center.
• If your door is more than 7 feet (2.13 m) high, see rail
extension kits listed on Accessories page 32.
Without a properly working safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
• The gap between the bottom of the garage door and the floor
MUST NOT exceed 1/4" (6 mm). Otherwise, the safety
reversal system may not work properly.
• The floor or the garage door MUST be repaired to eliminate
the gap.

Horizontal and vertical reinforcement (not provided) is
needed for light weight garage doors (fiberglass,
aluminum, steel, doors with glass panel, etc.).
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 your door
manufacturer for more information regarding
reinforcement of your door.
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 safety reversing sensor must be connected and
aligned correctly before the garage door opener will
move in the down direction.
NOTE: DO NOT operate the opener at this time.
IMPORTANT INFORMATION ABOUT THE SAFETY
REVERSING SENSOR
When properly connected and aligned, the sensor will
detect an obstacle in the path of its electronic beam. The
sending eye (with an amber indicator light) transmits an
invisible light beam to the receiving eye (with a green
indicator light). If an obstruction breaks the light beam
while the door is closing, the door will stop and reverse to
full open position, and the opener lights will flash 10 times.
The units must be installed inside the garage so that the
sending and receiving eyes face each other across the
door, no more than 6" (15 cm) above the floor. Either can
be installed on the left or right of the door as long as the
sun never shines directly into the receiving eye lens.
The mounting brackets are designed to clip onto the track
of sectional garage doors without additional hardware.

Facing the door from inside the garage
If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid surface
such as the wall framing. Extension brackets (see
accessories) are available if needed. If installing in
masonry construction, add a piece of wood at each
location to avoid drilling extra holes in masonry if
repositioning is necessary.
The invisible light beam path must be unobstructed. No
part of the garage door (or door tracks, springs, hinges,
rollers or other hardware) may interrupt the beam while
the door is closing.
To prevent SERIOUS INJURY or DEATH from a closing garage
door:
• Correctly connect and align the safety reversing sensor. This
required safety device MUST NOT be disabled.
• Install the safety reversing sensor so beam is NO HIGHER
than 6" (15 cm) above garage floor.

Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
• Incorrect adjustment of garage door travel limits will interfere
with proper operation of safety reversal system.
• If one control (force or travel limits) is adjusted, the other
control may also need adjustment.
• After ANY adjustments are made, the safety reversal system
must be tested. Door must reverse on contact with 1-1/2"
(3.8 cm) high object (or 2 x 4 laid flat) on floor.
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.

ADJUST THE UP AND DOWN TRAVEL LIMITS
Limit adjustment settings regulate the points at which the
door will stop when moving up or down.
To operate the opener, press the door control push bar.
Run the opener through a complete travel cycle.
• Does the door open and close completely?
• Does the door stay closed and not reverse
unintentionally when fully closed?
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test fails
(see Adjustment Step 3).
Adjustment procedures are outlined below. Read the
procedures carefully before proceeding to Adjustment Step
2. Use a screwdriver to make limit adjustments. Run the
opener through a complete travel cycle after each
adjustment.
NOTE: Repeated operation of the opener during
adjustment procedures may cause the motor to overheat
and shut off. Simply wait 15 minutes and try again.
NOTE: If anything interferes with the door’s upward travel,
it will stop. If anything interferes with the door’s downward
travel (including binding or unbalanced doors), it will
reverse.
HOW AND WHEN TO ADJUST THE LIMITS
•If the door does not open completely but opens at
least 5 feet (1.5 m):
Increase up travel. Turn the UP limit adjustment screw
clockwise. One turn equals 2" (5 cm) of travel.
NOTE: To prevent the trolley from hitting the cover
protection bolt, keep a minimum distance of 2-4"
(5-10 cm) between the trolley and the bolt.
•If door does not open at least 5 feet (1.5 m):
Adjust the UP (open) force as explained in Adjustment
Step 2.
•If the door does not close completely:
Increase down travel. Turn the DOWN limit adjustment
screw counterclockwise. One turn equals 2" (5 cm) of
travel.
