PLANNING  
WARNING  
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.  
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.  
• Do you have an access door in addition to the garage  
door? If not, Model 7702CB Outside Quick Release is  
required. See Accessories page.  
Depending on your requirements, there are several  
installation steps which may call for materials or hardware  
not included in the carton.  
• 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.  
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.  
• 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.  
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.  
• If your door is more than 7 feet (2.13 m) high, see rail  
extension kits listed on Accessories page 32.  
Installation Page 18 – Alternate floor mounting of the  
safety reversing sensor will require hardware not  
provided.

WARNING  
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 PROTECTOR SYSTEM  
• 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.  
NOTE: DO NOT operate the opener at this time.  
IMPORTANT INFORMATION ABOUT THE SAFETY  
REVERSING SENSOR  
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.  
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 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 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.

ADJUSTMENT  
WARNING  
Without a properly installed safety reversal system, persons  
(particularly small children) could be SERIOUSLY INJURED or  
KILLED by a closing garage door.  
ADJUSTMENT STEP 1  
• 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.  
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?  
CAUTION  
• Does the door stay closed and not reverse  
unintentionally when fully closed?  
To prevent damage to vehicles, be sure fully open door  
provides adequate clearance.  
If your door passes both of these tests, no limit  
adjustments are necessary unless the reversing test fails  
(see Adjustment Step 3).  
Cover Protection Bolt  
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.  
2-4"  
(5 cm-  
10 cm)  
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.  
Limit Adjustment Screws  
Left Side Panel  
ADJUSTMENT LABEL  
HOW AND WHEN TO ADJUST THE LIMITS  
Turn either limit adjustment screw the direction  
of the arrow to increase trolley travel, turn in  
the opposite direction to decrease travel  
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.  
If the opener reverses in fully closed position:  
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.  
Decrease down travel. Turn the DOWN limit adjustment  
screw clockwise. 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 does not open at least 5 feet (1.5 m):  
Adjust the UP (open) force as explained in Adjustment  
Step 2.  
If the opener lights are flashing, the Safety Reversing  
Sensors are either not installed, misaligned, or  
obstructed.  
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.

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.  
ADJUSTMENT STEP 2  
ADJUST THE FORCES  
• NEVER increase force beyond minimum amount required to  
close garage door.  
• NEVER use force adjustments to compensate for a binding or  
sticking garage door.  
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.  
• 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.  
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.  
Force Adjustment  
Controls  
HOW AND WHEN TO ADJUST THE FORCES  
KG  
KG  
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) obstruction. See  
Adjustment Step 3, page 22. 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.

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.  
If the door doesn’t open at least 5 feet (1.5 m),  
increase UP (open) force by turning the control  
clockwise. Make small adjustments until door opens  
completely. Readjust the UP limit if necessary. After  
each adjustment, run the opener through a complete  
travel cycle.

WARNING  
Without a properly installed safety reversal system, persons  
(particularly small children) could be SERIOUSLY INJURED or  
KILLED by a closing garage door.  
ADJUSTMENT STEP 3  
• Safety reversal system MUST be tested every month.  
• If one control (force or travel limits) is adjusted, the other  
control may also need adjustment.  
TEST THE SAFETY REVERSAL SYSTEM  
Test  
• 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 the floor.  
• With the door fully open, place a 1-1/2" (3.8 cm) board  
(or a 2 x 4 laid flat) on the floor, centered under the  
garage door.  
• 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 travel  
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 page 14.  
1-1/2" (3.8 cm) board (or a 2x4 laid flat)  
• Repeat the test.  
• When the door reverses on the 1-1/2" (3.8cm) (or a 2x4  
laid flat) board, remove the obstruction and run the  
opener through 3 or 4 complete travel cycles to test  
adjustment.  
®
TEST THE PROTECTOR SYSTEM  
• Press the remote control push button to open the door.  
• Place the opener carton in the path of the door.  
WARNING  
Without a properly installed safety reversing sensor, persons  
(particularly small children) could be SERIOUSLY INJURED or  
KILLED by a closing garage door.  
• Press the remote control push button to close the door.  
The door will not move more than an inch, 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" (25 mm) above the floor), call for a trained door  
systems technician.
