Preparing your garage door
WARNING
Before you begin:
To prevent possible SERIOUS INJURY OR DEATH:
• Disable locks.
• 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.
• 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.
CAUTION
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

Planning
• Do you have an access door in addition to the
garage door? If not, Model 7702CB Outside Quick
Release is required. See Accessories page.
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 find it helpful to
refer back to this page and the accompanying
illustrations as you proceed with the installation of
your opener.
• 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.
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.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforce-
ment is required (Installation Step 11).
• Installation Step 5 – Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• 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. See Installation
Steps 1 and 11.
• Installation Step 10 – Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 10 – Alternate floor mounting of
the safety reversing sensor will require hardware
not provided.
• If your door is more than 7 feet (2.13 m) high, see
rail extension kits listed on Accessories page.

reinforcement. If your door is lightweight, refer to
the information relating to sectional doors in
Installation Step 11.
• 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.
• Depending on your door’s construction, you may
need additional mounting hardware for the door
bracket (Step 11).

Electrical Requirements
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
To avoid installation difficulties, do not run the
opener at this time.
• Be sure power is not connected to the opener, and
disconnect power to circuit BEFORE removing cover to
establish permanent wiring connection.
• Garage door installation and wiring MUST be in
compliance with all local electrical and building codes.
• NEVER use an extension cord, 2-wire adapter, or
change plug in any way to make it fit outlet. Be sure
the opener is grounded.
To reduce the risk of electric shock, your garage door

INSTALLATION STEP 10
WARNING
®
Install The Protector System
Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
The safety reversing sensor must be connected
and aligned correctly before the garage door
opener will move in the down direction.
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.
IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
• Install the safety reversing sensor so beam is NO
HIGHER than 6" (15 cm) above garage floor.
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.
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 units must be installed inside the garage so that
the sending and receiving eyes face each other
across the door, no more than 6" 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 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.
The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.

MOUNTING AND WIRING THE SAFETY SENSORS
Figure 4
• Slide a 1/4"-20x1/2" carriage bolt head into the slot
on each sensor. Use wing nuts to fasten sensors to
brackets, with lenses pointing toward each other
across the door. Be sure the lens is not obstructed
by a bracket extension (Figure 4).
Wing nut

• Finger tighten the wing nuts.
Lens
• Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.
TROUBLESHOOTING THE SAFETY SENSORS
• Strip 7/16" (11 mm) of insulation from each set of
wires. Separate white and white/black wires
sufficiently to connect to the opener quick-connect
terminals. Twist like colored wires together. Insert
wires into quick-connect holes: white to white and
white/black to black (Figure 5).
1. If the sending eye indicator light does not glow
steadily after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These
can occur at staples, or at opener connections.
• Incorrect wiring between sensors and opener.
• A broken wire.
ALIGNING THE SAFETY SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glow steadily if
wiring connections and alignment are correct.
2. If the sending eye indicator light glows steadily but
the receiving eye indicator light doesn't:
• Check alignment.
The sending eye amber indicator light will glow
regardless of alignment or obstruction. If the green
indicator light in the receiving eye is off, dim, or
flickering (and the invisible light beam path is not
obstructed), alignment is required.
• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign
either sensor.
NOTE: When the invisible beam path is obstructed
or misaligned while the door is closing, the door will
reverse. If the door is already open, it will not close.
The opener lights will blink 10 times. (If bulbs are not
installed, 10 clicks can be heard.) See page 21.
• Loosen the sending eye wing nut and readjust,
aiming directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust
sensor until it receives the sender’s beam. When
the green indicator light glows steadily, tighten the
wing nut.

On one-piece doors, before connecting the door
arm to the trolley, the travel limits must be
adjusted. Limit adjustment screws are located on
the left side panel as shown on page 28. Follow
adjustment procedures below.
– Manually close the door and lift the door arm to
the trolley. The arm should touch the trolley just
ahead of the door arm connector hole. Refer to
the fully closed trolley/door arm positions in the
illustration. If the arm is behind the connector
hole, adjust the limit further. One full turn
equals 2" (5 cm) of trolley travel.
• Open door adjustment: decrease UP travel
limit
– Turn the UP limit adjustment screw counter-
clockwise 5-1/2 turns.
3. Connect the door arm to the trolley:
• Close the door and join the curved arm to the
connector hole in the trolley with the remaining
clevis pin. It may be necessary to lift the door
slightly to make the connection.
– Press the Door Control push bar. The trolley
will travel to the fully open position.
– Manually raise the door to the open position
(parallel to the floor), and lift the door arm to
the trolley. The arm should touch the trolley just
in back of the door arm connector hole. Refer
to the fully open trolley/door arm positions in
the illustration. If the arm does not extend far
enough, adjust the limit further. One full turn
equals 2" (5 cm) of trolley travel.
• Secure with a ring fastener.
• Run the opener through a complete travel cycle. If
the door has a slight "backward" slant in full open
position as shown in the illustration, decrease the
UP limit until the door is parallel to the floor.
NOTE: When setting the up limit on the following
page, the door should not have a "backward" slant
when fully open as illustrated below. A slight
backward slant will cause unnecessary bucking
and/or jerking operation as the door is being opened
or closed from the fully open position.
• Closed door adjustment: decrease DOWN

ADJUSTMENT STEP 1
WARNING
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.
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?
• 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 2x4
laid flat) on floor.
• 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, page 30).
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.
CAUTION
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.
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.
Cover Protection Bolt
NOTE: If anything interferes with the door’s upward

ADJUSTMENT LABEL
• 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 opener reverses in fully closed position:
• If the door does not close completely:
Decrease down travel. Turn the down limit
adjustment screw clockwise. One turn equals 2"
(5 cm) of travel.
Increase down travel. Turn the down limit
adjustment screw counterclockwise. One turn
equals 2" (5 cm) of travel.
• If the door reverses when closing and there is
no visible interference to travel cycle:
If door still won't close completely and the trolley
bumps into the pulley bracket (see page 4 or 5),
try lengthening the door arm (page 26) and
decreasing the down limit.
If the opener lights are flashing, the Safety
Reversing Sensors are either not installed,
misaligned, or obstructed. See Troubleshooting,
page 23.
Test the door for binding: Pull the emergency
release handle. Manually open and close the door.
If the door is binding or unbalanced, call for a
trained door systems technician. If the door is
balanced and not binding, adjust the DOWN
(close) force. See Adjustment Step 2.

ADJUSTMENT STEP 2
WARNING
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Too much force on garage door will interfere with
proper operation of safety reversal system.
• NEVER increase force beyond minimum amount
required to close garage door.
• NEVER use force adjustments to compensate for a
binding or sticking garage door.
• 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 2x4
laid flat) on floor.
Adjust the Force
Force adjustment controls are located on the back
panel of the motor unit. Force adjustment settings
regulate the amount of power required to open and
close the door.
If the forces are set too light, door travel may be
interrupted by nuisance reversals in the down
direction and stops in the up direction. Weather
conditions can affect the door movement, so
occasional adjustment may be needed.
The maximum force adjustment range is about
3/4 of a complete turn. Do not force controls
beyond that point. Turn force adjustment controls
with a screwdriver.
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.

1. Test the DOWN (close) force
• Grasp the door bottom when the door is about
halfway through DOWN (close) travel. The door
should reverse. Reversal halfway through down
travel does not guarantee reversal on a one-inch
obstruction. See Adjustment Step 3, page 30.
If the door is hard to hold or doesn't reverse,
DECREASE the DOWN (close) force by turning
the control counterclockwise. Make small
adjustments until the door reverses normally. After
each adjustment, run the opener through a
complete cycle.

WARNING
Test the Safety Reversal System
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
TEST
• With the door fully open, place a 1-1/2" board (or a
2x4 laid flat) on the floor, centered under the
garage door.
• Safety reversal system MUST be tested every month.
• 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" high object (or 2x4 laid flat) on the
floor.
• Operate the door in the down direction. The door
must reverse on striking the obstruction.
ADJUST
• If the door stops on the obstruction, it is not
traveling far enough in the down direction.
Increase the DOWN limit by turning the DOWN
limit adjustment screw counterclockwise 1/4 turn.
NOTE: On a sectional door, make sure limit
adjustments do not force the door arm beyond a
straight up and down position. See the illustration
on page 26.
• Repeat the test.
• When the door reverses on the 1-1/2" board,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test adjustment.
IMPORTANT SAFETY CHECK:
Repeat Adjustment Steps 1, 2 and 3 after:
• Each adjustment of door arm length, limits, or
force controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
1-1/2" board (or a 2x4 laid flat)
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.

6. The garage door opens and closes by itself:
• Be sure that all remote control push buttons are
off.
• Check the safety reversing sensor. Remove any
obstruction or align the receiving eye. See
Installation Step 10.
• Remove the bell wire from the door control
terminals and operate from the remote only. If this
solves the problem, the door control is faulty
(replace), or there is an intermittent short on the
wire between the door control and the motor unit.
12. The opener lights don't turn on:
• Replace the light bulbs (100 watts maximum). Use
a standard neck garage door opener bulb if regular
bulb burns out.
• Clear memory and re-program all remote controls.
13. The opener lights don't turn off:
7. The door doesn't open completely:
• Is the Light feature on? Turn it off.
• Is something obstructing the door? Is it out of
balance, or are the springs broken? Remove the
obstruction or repair the door.
14. The opener strains or maximum force is
needed to operate door:
• The door may be out of balance or the springs
may be broken. Close the door and use the
emergency release handle to disconnect the
trolley. Open and close the door manually. A
properly balanced door will stay in any point of
travel while being supported entirely by its springs.
If it does not, disconnect the opener and call a
trained door systems technician. Do not increase
the force to operate the opener.
• If the door is in good working order but now
doesn't open all the way, increase the up force.
See Adjustment Step 2.
• If the door opens at least 5 feet (1.5 m), the travel
limits may need to be increased. One turn equals
2 inches of travel. See Adjustment Step 1.
Repeat the safety reverse test after the adjustment is
complete.
8. The door stops but doesn't close completely:
15. The opener motor hums briefly, then won't
work:
• Review the travel limits adjustment procedures on
page 28.
• The garage door springs may be broken. See
above.
Repeat the safety reverse test after any adjustment
of door arm length, close force or down limit.
• If the problem occurs on the first operation of the
opener, door may be locked. Disable the door lock.
9. The door opens but won't close:
Repeat the safety reverse test after the adjustment is
complete.
• If the opener lights blink, check the safety
reversing sensor. See Installation Step 10.
16. The opener won't operate due to power
failure:
• If the opener lights don’t blink and it is a new
installation, check the down force. See Adjustment
Step 2, page 29. For an existing installation, see
below.
• Use the emergency release handle to disconnect
the trolley. The door can be opened and closed
manually. When power is restored, press the Door
Control push bar and trolley will automatically
reconnect (unless trolley is in lockout position.)
See page 32.
Repeat the safety reverse test after the adjustment
is complete.
10. The door reverses for no apparent reason and
opener lights don’t blink:
• The Outside Quick Release accessory (for use on
garages with no service door) disconnects the
trolley from outside the garage in case of power
failure.
• Is something obstructing the door? Pull the
emergency release handle. Operate the door
manually. If it is unbalanced or binding, call a
trained door systems technician.
17. The chain droops or sags:
• Clear any ice or snow from the garage floor area
where the door closes.
• It is normal for the chain to droop slightly in the
closed door position. Use the emergency release
rope and handle to disconnect the trolley. If the
chain returns to the normal height when the trolley
is disengaged, and the door reverses on a 2x4 laid
flat, no adjustments are needed. (See page 11.)
• Review Adjustment Step 2 on page 29.
• If door reverses in the fully closed position,
decrease the travel limits (Adjustment Step 1).
Repeat safety reverse test after adjustments to force
or travel limits. The need for occasional adjustment
of the force and limit settings is normal. Weather
conditions in particular can affect door travel.

that it is free from defect in materials and/or workmanship for a period of one year from the date of purchase [and that the motor is free from defect in

with the instructions regarding installation, operation, maintenance and testing. Failure to comply strictly with those instructions will void this limited
warranty in its entirety.
If, during the limited warranty period, this product appears to contain a defect covered by this limited warranty, call 1-800-528-9131, toll free, before
dismantling this product. Then send this product, pre-paid and insured, to our service center for warranty repair. You will be advised of shipping instructions
when you call. Please include a brief description of the problem and a dated proof-of-purchase receipt with any product returned for warranty repair.
Products returned to Seller for warranty repair, which upon receipt by Seller are confirmed to be defective and covered by this limited warranty, will be
repaired or replaced (at Seller's sole option) at no cost to you and returned pre-paid. Defective parts will be repaired or replaced with new or factory-rebuilt
parts at Seller's sole option.
ALL IMPLIED WARRANTIES FOR THE PRODUCT, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO THE ONE YEAR LIMITED WARRANTY PERIOD SET FORTH ABOVE
[EXCEPT THE IMPLIED WARRANTIES WITH RESPECT TO THE MOTOR, WHICH IS LIMITED IN DURATION TO THE 6 YEAR LIMITED WARRANTY
PERIOD FOR THE MOTOR], AND NO IMPLIED WARRANTIES WILL EXIST OR APPLY AFTER SUCH PERIOD. Some provinces do not allow
limitations on how long an implied warranty lasts, so the above limitation may not apply to you. THIS LIMITED WARRANTY DOES NOT COVER
NON-DEFECT DAMAGE, DAMAGE CAUSED BY IMPROPER INSTALLATION, OPERATION OR CARE (INCLUDING, BUT NOT LIMITED TO ABUSE,
MISUSE, FAILURE TO PROVIDE REASONABLE AND NECESSARY MAINTENANCE, UNAUTHORIZED REPAIRS OR ANY ALTERATIONS TO THIS
PRODUCT), LABOR CHARGES FOR REINSTALLING A REPAIRED OR REPLACED UNIT, REPLACEMENT OF BATTERIES AND LIGHT BULBS OR

WARRANTY ALSO DOES NOT COVER ANY PROBLEMS CAUSED BY INTERFERENCE. ANY SERVICE CALL THAT DETERMINES THE PROBLEM
HAS BEEN CAUSED BY ANY OF THESE ITEMS COULD RESULT IN A FEE TO YOU.
UNDER NO CIRCUMSTANCES SHALL SELLER BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL OR SPECIAL DAMAGES ARISING IN
CONNECTION WITH USE, OR INABILITY TO USE, THIS PRODUCT. IN NO EVENT SHALL SELLER'S LIABILITY FOR BREACH OF WARRANTY,
BREACH OF CONTRACT, NEGLIGENCE OR STRICT LIABILITY EXCEED THE COST OF THE PRODUCT COVERED HEREBY. NO PERSON IS
AUTHORIZED TO ASSUME FOR US ANY OTHER LIABILITY IN CONNECTION WITH THE SALE OF THIS PRODUCT.
Some states do not allow the exclusion or limitation of consequential, incidental or special damages, so the above limitation or exclusion may not apply
to you. This limited warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
