Preparing your garage door  
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.  
• 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:  
• 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.  
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 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  
malfunction and damage.

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 find it helpful to refer back to this page  
and the accompanying illustrations as you proceed with  
the installation of your opener.  
• 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 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  
reinforcement 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.

Planning (Continued)  
ONE-PIECE DOOR INSTALLATIONS  
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.  
• Generally, a one-piece door does not require  
reinforcement. If your door is lightweight, refer to the  
information relating to sectional doors in Installation  
Step 11.  
• Depending on your door’s construction, you may need  
additional mounting hardware for the door bracket  
(Step 11).  
• The floor or the garage door MUST be repaired to eliminate  
the gap.

ASSEMBLY STEP 1  
Assemble the Rail & Install the Trolley  
To prevent INJURY from pinching, keep hands and fingers  
away from the joints while assembling the rail.  
To avoid installation difficulties, do not run the  
garage door opener until instructed to do so.  
The front rail has a cut out “window” at the door end (see  
illustration). The hole above this window is larger on  
the top of the rail than on the bottom. A smaller hole 3-  
1/2" (8.9 cm) away is close to the rail edge. Rotate the  
back rail so it has a similar hole close to the opposite  
edge, about 4-3/4" (12 cm) from the far end.  
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 trolley stop, insert a screwdriver into the  
hole 10" (25 cm) away from the front of the rail, as  
shown.  
1. Remove the straight door arm and hanging bracket  
packaged inside the front rail and set aside for  
Installation Step 5 and 12. NOTE: To prevent INJURY  
while unpacking the rail carefully remove the straight  
door arm stored within the rail section.  
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.  
2. Align the rail sections on a flat surface as shown and  
slide the tapered ends into the larger ones. Tabs along  
the side will lock into place.  
6. Slide the trolley assembly along the rail from the back  
end to the screwdriver.

INSTALLATION STEP 5  
Hang the Opener  
To avoid possible SERIOUS INJURY from a falling garage door  
opener, fasten it SECURELY to structural supports of the  
garage. Concrete anchors MUST be used if installing any  
brackets into masonry.  
Three representative installations are shown. Yours may  
be different. Hanging brackets should be angled (Figure 1)  
to provide rigid support. On finished ceilings (Figure 2 and  
Figure 3), attach a sturdy metal bracket to structural  
supports before installing the opener. This bracket and  
fastening hardware are not provided.

INSTALLATION STEP 6  
Install the Door Control  
To prevent possible SERIOUS INJURY or DEATH from  
electrocution:  
Locate door control within sight of door at a minimum  
height of 5 feet (1.5 m) where small children cannot  
reach, and away from moving parts of door and door  
hardware. The installation surface must be smooth and  
flat. If installing into drywall (Figure 1), drill 5/32" holes  
and use anchors provided. For pre-wired installations (as  
in new home construction), it may be mounted to a single  
gang box (Figure 2). NOTE: After installation, a green or  
amber indicator light behind the cover will indicate proper  
connection. If not lit, the Lock and Light features will not  
function (reverse wires to correct).  
• Be sure power is not connected BEFORE installing door  
control.  
• Connect ONLY to 24 VOLT low voltage wires.  
To prevent possible SERIOUS INJURY or DEATH from a closing  
garage door:  
• Install door control within sight of garage door, out of reach  
of children at a minimum height of 5 feet (1.5 m), and away  
from all moving parts of door.  
• NEVER permit children to operate or play with door control  
push buttons or remote control transmitters.  
1. Strip 7/16" (11 mm) of insulation from one end of bell  
wire and connect to the two screw terminals on back of  
door control by color: white wire to WHT and white/red  
wire to the RED (Figure 3).  
2. Remove cover by gently prying on a side corner near  
the top of the cover with a small flat head screwdriver  
(Figure 4). Fasten with 6ABx1-1/4" self-tapping screws  
(drywall installation) or 6-32x1" machine screws (into  
gang box) as follows:  
• Activate door ONLY when it can be seen clearly, is properly  
adjusted, and there are no obstructions to door travel.  
• ALWAYS keep garage door in sight until completely closed.  
NEVER permit anyone to cross path of closing garage door.

INSTALLATION STEP 8  
Attach the Emergency Release Rope  
and Handle  
To prevent possible SERIOUS INJURY or DEATH from a falling  
garage door:  
• If possible, use emergency release handle to disengage  
trolley ONLY when garage door is CLOSED. Weak or broken  
springs or unbalanced door could result in an open door  
falling rapidly and/or unexpectedly.  
• NEVER use emergency release handle unless garage  
doorway is clear of persons and obstructions.  
• NEVER use handle to pull door open or closed. If rope knot  
becomes untied, you could fall.  
• Thread one end of the rope through the hole in the top  
of the red handle so “NOTICE” reads right side up as  
shown. Secure with an overhand knot at least 1"  
(2.5 cm) from the end of the rope to prevent slipping.  
• Thread the other end of the rope through the hole in the  
release arm of the outer trolley.  
• Adjust rope length so the handle is 6 feet (1.83 m)  
above the floor. Ensure that the rope and handle clear  
the tops of all vehicles to avoid entanglement. Secure  
with an overhand knot.  
NOTE: If it is necessary to cut the rope, heat seal the cut  
end with a match or lighter to prevent unraveling.

Electrical Requirements  
To prevent possible SERIOUS INJURY or DEATH from  
electrocution or fire:  
• 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 avoid installation difficulties, do not run the  
opener at this time.  
To reduce the risk of electric shock, your garage door  
opener has a grounding type plug with a third grounding  
pin. This plug will only fit into a grounding type outlet. If  
the plug doesn't fit into the outlet you have, contact a  
qualified electrician to install the proper outlet.

INSTALLATION STEP 10  
Install The Protector System  
®
Be sure power is not connected to the garage door opener  
BEFORE installing the safety reversing sensor.  
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.  
The safety reversing sensor must be connected and  
aligned correctly before the garage door opener will  
move in the down direction.  
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.  
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" (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 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.

• Finger tighten the wing nuts.  
Run the wires from both sensors to the opener. Use  
insulated staples to secure wire to wall and ceiling.  
TROUBLESHOOTING THE SAFETY  
REVERSING 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  
grey (Figure 6).  
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 REVERSING 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 orange 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. See page 20.  
• 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.

2. Adjustment procedures, Figure 5:  
• 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 27. 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 3" (7.5 cm) of trolley travel.  
• Open door adjustment: decrease UP travel limit  
- Turn the UP limit adjustment screw counter-clockwise  
4 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 button. 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 3" (7.5 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 travel  
limit  
- Turn the DOWN limit adjustment screw clockwise  
4 complete turns.

ADJUSTMENT STEP 1  
Adjust the UP and DOWN Travel Limits  
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.  
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.  
• If one control (force or travel limits) is adjusted, the other  
control may also need adjustment.  
• Does the door open and close completely?  
• After ANY adjustments are made, the safety reversal system  
MUST be tested. Door MUST reverse on contact with 1-1/2"  
high (3.8 cm) 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  
(Adjustment Step 3, page 29).  
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.  
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  
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 five feet (1.5 m):  
Left Panel  
Limit Adjustment Screws  
Increase up travel. Turn the UP limit adjustment screw  
clockwise. One turn equals 3" (7.5 cm) of travel.  
NOTE: To prevent the trolley from hitting the cover  
protection bolt, keep a minimum distance of 2-4"  
(5 cm - 10 cm) between the trolley and the bolt.  
• If door does not open at least 5 feet (1.5 m):  
ADJUSTMENT LABEL  
Adjust the UP (open) force as explained in Adjustment  
Step 2.  
• If the door does not close completely:  
• If the door reverses when closing and there is no  
visible interference to travel cycle:  
Increase down travel. Turn the down limit adjustment  
screw counterclockwise. One turn equals 3" (7.5 cm) of  
travel.  
If the opener lights are flashing, the Safety Reversing  
Sensors are either not installed, misaligned, or  
obstructed. See Troubleshooting, page 22.  
If door still won't close completely and the trolley bumps  
into the pulley bracket (page 4), try lengthening the  
door arm (page 25) and decreasing the down limit.  
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.  
• If the opener reverses in fully closed position:  
Decrease down travel. Turn the down limit adjustment  
screw clockwise. One turn equals 3" (7.5 cm) of travel.

ADJUSTMENT STEP 2  
Adjust the Force  
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"  
high (3.8 cm) object (or 2x4 laid flat) on floor.  
Force adjustment controls are located on the right 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.  
HOW AND WHEN TO ADJUST THE FORCES  
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 1-1/2" (3.8 cm)  
Force Adjustment Controls

obstruction. See Adjustment Step 3, page 29. 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.

close cycle. After each adjustment, run the opener  
through a complete travel cycle. Do not increase the  
force beyond the minimum amount required to close  
the door.

2. Test the UP (open) force  
• Grasp the door bottom when the door is about halfway  
through UP (open) travel. The door should stop. If the  
door is hard to hold or doesn't stop, DECREASE  
UP (open) force by turning the control  
counterclockwise. Make small adjustments until the  
door stops easily and opens fully. After each  
adjustment, run the opener through a complete  
travel cycle.  
Open Force

ADJUSTMENT STEP 3  
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  
• Safety reversal system MUST be tested every month.  
• If one control (force or travel limits) is adjusted, the other  
control may also need adjustment.  
• With the door fully open, place a 1-1/2" (3.8 cm) board  
(or a 2x4 laid flat) on the floor, centered under the  
garage door.  
• After ANY adjustments are made, the safety reversal system  
MUST be tested. Door MUST reverse on contact with 1-1/2"  
high (3.8 cm) 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 25.  
• Repeat the test.  
• When the door reverses on the 1-1/2" (3.8 cm) board,  
remove the obstruction and run the opener through 3 or  
4 complete travel cycles to test adjustment.  
• If the unit continues to fail the Safety Reverse Test, call  
for a trained door systems technician.  
IMPORTANT SAFETY CHECK:  
Test the Safety Reverse System after:  
• Each adjustment of door arm length, limits, or force  
controls.  
1-1/2" (3.8 cm) board  
(or a 2x4 laid flat)  
• Any repair to or adjustment of the garage door  
(including springs and hardware).  
• Any repair to or buckling of the garage floor.  
• Any repair to or adjustment of the opener.  
ADJUSTMENT STEP 4  
Test The Protector System

(particularly small children) could be SERIOUSLY INJURED or  
KILLED by a closing garage door.  
• Press the remote control push button to open the door.  
• Place the opener carton in the path of the door.  
• Press the remote control push button to close the door.  
The door will not move more than an inch (2.5 cm), and  
the opener lights will flash.  
The garage door opener will not close from a remote if the  
indicator light in either sensor is off (alerting you to the fact  
that the sensor is misaligned or obstructed).  
If the opener closes the door when the safety  
reversing sensor is obstructed (and the sensors are  
no more than 6" (15 cm) above the floor), call for a  
trained door systems technician.
