Preparing your garage door  
Before you begin:  
Disable locks.  
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.  
To prevent possible SERIOUS INJURY or DEATH:  
• 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.  
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.  
Depending on your requirements, there are several  
installation steps which may call for materials or hardware  
not included in the carton.  
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.  
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 finished 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 floor mounting of  
the safety reversing sensor will require hardware not  
provided.  
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).  
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.

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 avoid installation difficulties, do not run the garage  
door opener until instructed to do so.  
To prevent INJURY from pinching, keep hands and  
fingers away from the joints while assembling the rail.  
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.  
1. Remove the straight door arm and hanging bracket  
packaged inside the front rail and set aside for  
Installation Step 5 and 12.  
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.  
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.  
NOTE: To prevent INJURY while unpacking the rail  
carefully remove the straight door arm stored within the  
rail section.  
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.

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:  
• 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.  
• 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.  
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).  
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 at slot in side of the  
cover with a small flat head screwdriver (Figure 4).  
Fasten with 6ABx1-1/4" self-tapping screws (drywall

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.  
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.  
• NEVER use handle to pull door open or closed. If  
rope knot becomes untied, you could fall.

INSTALLATION STEP 9  
Electrical Requirements  
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.  
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.

INSTALLATION STEP 10  
Install The Protector System®  
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.  
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.  
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.  
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.  
The mounting brackets are designed to clip onto the track  
of sectional garage doors without additional hardware.

connections and alignment are correct.  
1. If the sending eye indicator light does not glow steadily  
after installation, check for:  
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.  
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.  
Loosen the sending eye wing nut and readjust, aiming  
directly at the receiving eye. Lock in place.  
2. If the sending eye indicator light glows steadily but the  
receiving eye indicator light doesn’t:  
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.  
Check alignment.  
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.

INSTALLATION STEP 11  
Fasten the Door Bracket  
Follow instructions which apply to your door type  
as illustrated below or on the following page.  
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.  
Fiberglass, aluminum or lightweight steel garage  
doors WILL REQUIRE reinforcement BEFORE  
installation of door bracket. Contact your door  
manufacturer for reinforcement kit.  
Header  
Bracket  
Figure 1 shows one piece of angle iron as the horizontal  
brace. For the vertical brace, 2 pieces of angle iron are  
used to create a U-shaped support. The best solution is to  
check with your garage door manufacturer for an opener  
installation door reinforcement kit.  
NOTE: 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 Step 12.

ADJUSTMENT STEP 1  
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.  
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" high (3.8 cm) object (or 2x4 laid  
flat) on floor.  
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  
(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.  
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.  
To prevent damage to vehicles, be sure fully open  
door provides adequate clearance.  
Cover Protection Bolt  
HOW AND WHEN TO ADJUST THE LIMITS  
If the door does not open completely but opens at  
least five feet (1.5 m):  
Increase up travel. Turn the UP limit adjustment screw  
clockwise. One turn equals 3" (7.5 cm) of travel.  
2-4"  
(5-10 cm)  
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):  
Left Panel  
Adjust the UP (open) force as explained in Adjustment  
Step 2.  
If the door does not close completely:  
Limit Adjustment Screws  
Increase down travel. Turn the down limit adjustment  
screw counterclockwise. One turn equals 3" (7.5 cm) of  
travel.  
If door still won't close completely and the trolley  
bumps into the pulley bracket (page 4), try lengthening  
the door arm (page 26) and decreasing the down limit.  
ADJUSTMENT LABEL  
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.  
If the door reverses when closing and there is no  
visible interference to travel cycle:  
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.  
28  
Download from Www.Somanuals.com. All Manuals Search And Download.  
ADJUSTMENT STEP 2  
Adjust the Force  
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.  
Without a properly installed safety reversal system,  
persons (particularly small children) could be  
SERIOUSLY INJURED or KILLED by a closing garage  
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.  
• 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.  
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.  
• 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.  
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)  
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.  
Force Adjustment Controls  
Right Panel  
If the door reverses during the down (close) cycle  
and the opener lights aren't flashing, INCREASE  
DOWN (close) force by turning the control clockwise.  
Make small adjustments until the door completes a  
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.  
FORCE ADJUSTMENT LABEL  
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  
Close Force  
• 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.

ADJUSTMENT STEP 3  
Test the Safety Reversal System  
TEST  
Without a properly installed safety reversal system,  
persons (particularly small children) could be  
SERIOUSLY INJURED or KILLED by a closing garage  
door.  
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.  
• Safety reversal system MUST be tested every month.  
Operate the door in the down direction. The door must  
reverse on striking the obstruction.  
• 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 the floor.  
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" (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.  
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.

Test The Protector System  
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 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.

• Release the door from the opener by pulling the  
Emergency Release Rope.  
• Manually bring the door to a closed position.  
• Loosen the chain by adjusting the outer nut 4 to 5

Travel Limits. Decrease down travel by turning down  
limit adjustment screw clockwise.  
• Re-tighten the outer nut so the chain is a 1/4"  
(6 mm) above the base of the rail. (When the door  
is reconnected and closed, the chain will sag. This is  
normal.)  
• If the trolley does not move away from the bolt,  
repeat the steps above.  
5. My lights will not turn off when door is open:  
• The garage door opener is equipped with a security  
light feature. This feature activates the light on  
when the safety reversing sensor beam has been  
obstructed. Refer to Operation section; Using the  
Wall-Mounted Door Control, Light Feature.
