WARNING  
CAUTION  
To avoid damage to the garage door and  
opener, disable locks before installing and  
operating the opener. Use a wood screw or nail  
to hold locks in the "open" (unlocked)  
position.  
Ropes left on a garage door could cause  
someone to become entangled and killed.  
Remove all ropes connected to the door before  
installing and operating the opener.  
Operation at other than 120V 60 Hz will cause  
opener malfunction and damage.  
WARNING  
This product is for use on sectional garage  
doors only. Serious personal injury could  
result from the use of this product on one-  
piece garage doors.  
Before you begin, complete the following test to make sure your door is balanced and is not sticking or  
binding. Identify the type and height of your door, any special conditions that exist, and any additional  
materials that may be required by referring to the lists on page 4.  
• Lift the door about halfway as shown. Release the  
door. It should stay in place, supported entirely by  
its springs.  
• Raise and lower the door to see if there is any  
binding or sticking.  
An unbalanced garage door might not reverse  
when required and someone under the door  
could be seriously injured or killed.  
If your garage door binds, sticks or is out of  
balance, call for professional garage door  
service. Garage doors, door springs, cables,  
pulleys, brackets and their hardware, are under  
extreme tension and can cause serious injury or  
death. Do not try to loosen, move or adjust them  
yourself!

center bearing plate in the way of the header bracket  
or door bracket area. If your door has extension  
springs, the opener must be installed in the center of  
the door. See pages 8 and 19.  
• Look at the garage door where it meets the floor. It  
must close on the floor all the way across. Other-  
wise, the safety reverse system may not work  
properly. See page 23. Floor or door should be  
repaired.  
Do you have an access door in addition to the garage  
door? If not, Model 1702 Outside Quick Release is  
required. See page 30.  
• If your door is more than 7 feet high, see longer  
rails available on page 30.

Installation Step 1  
Determine Header Bracket Location  
WARNING  
If the header bracket is not rigidly fastened to  
a structural support on the header wall or  
ceiling, the safety reverse system may not  
work properly (see page 23). The door might  
not reverse when required, and could cause  
serious injury or death.  
The garage door springs, cables, pulleys,  
brackets and their hardware are under extreme  
tension. Do not attempt to loosen, move or  
adjust them yourself. Serious personal injury  
or death could result. Call for garage door  
service.

Installation Step 6  
Install the Door Control  
WARNING  
Children operating or playing with a garage  
door opener can injure themselves or others.  
The garage door could close and cause  
serious injury or death.  
• Strip 1/4" of insulation from one end of the bell  
wire; connect the wire to the two screw terminals  
on the back of the Door Control by color, white to  
2, and white/red to 1.  
Install the Door Control (or any additional push  
buttons) out of the reach of children and away  
from all moving parts of the door and door  
hardware, but where the garage door is visible.  
Do not allow children to operate the push  
button(s) or the remote control transmitter(s).  
• Locate the door control within sight of the door at a  
minimum height of 5 feet where small children  
cannot reach, and away from all moving parts of  
the door and door hardware. Fasten the Door  
Control Button securely with 6ABx1-1/2" screws. If  
installing into drywall, drill 5/32" holes and use the  
anchors provided.  
A moving garage door could injure someone  
under it. Activate the opener only when the  
door is properly adjusted, you can see it  
clearly, and there are no obstructions to door  
travel.  
• Run the bell wire up the wall and across the ceiling  
to the opener. Use insulated staples to secure the  
wire in several places. Be careful not to pierce the  
wire with a staple, thereby resulting in a short.  
Do NOT connect the power and operate the  
opener at this time. The trolley will travel to the  
full open position but will not return to the  
close position until the sensor beam is  
connected and properly aligned.  
See Safety Reversing Sensor Instructions  
beginnning on page 16.  
• Receiver terminal screws and the antenna are  
located on the back panel of the opener. Position  
the antenna wire as shown.  
• Then connect the bell wire by color to the opener  
terminal screws: white to 2 and white/red to 1.  
Remember to affix the User Safety Instruction  
label to the wall near the door control, and the  
Maintenance Instruction Label in a prominent  
location on the inside of the garage door.

Electrical Requirements  
WARNING  
To prevent electrocution or fire, installation  
and wiring must be in compliance with local  
electrical and building codes.  
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.  
Right  
Wrong  
• Do not change the plug in any way.  
• Do not use a 2-wire adapter.  
To avoid installation difficulties,  
do not run the opener at this time.  
• Do not use an extension cord.  
If permanent wiring is required by your local code, refer to the following procedure:  
WARNING  
To prevent electrocution, remove power from  
the garage door opener and from the circuit  
you plan to use for the permanent  
connection.  
To make a permanent connection through the 7/8"  
diameter hole in the top of the opener (according  
to local code):  
Permanent wiring  
connection  
• Remove the opener cover screws and set the  
cover aside.  
• Remove the attached 3-prong cord.  
• Connect the black (line) wire to the screw on the  
brass terminal; the white (neutral) wire to the  
screw on the silver terminal; and the ground wire  
to the green ground screw. The opener must be  
grounded.

Information you'll need before you begin the installation of 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. This is a  
WARNING  
required safety device and cannot be disabled.  
Without a properly working safety reversing  
sensor, persons (particularly children) could  
be killed by a closing garage door. Read and  
follow all instructions.  
To protect small children, install the safety  
reversing sensor so that the beam will be no  
higher than 4-6" above the garage floor.  
Disconnect power to the garage door opener  
before installing the safety reversing sensor.

Be sure power to the opener is disconnected.  
The brackets must be securely fastened to a solid  
surface such as the studs on either side of the door,  
or add a piece of wood at each location if installing in  
masonry construction.  
The sending eye transmits an invisible light beam to  
the receiving eye. The units can be installed on  
either side of the garage 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) can interrupt the  
beam while the door is closing. If it does, use a piece  
of wood to build out each sensor mounting location to  
the minimum depth required for light beam clearance.  
Look at the label on the connector end of each case  
to identify the sensors.  
The brackets must be connected and fastened so  
that the sending and receiving eyes face each other  
as shown in Figure 1.  
If an obstruction breaks the light beam while the  
garage door is closing, the door will stop and  
reverse to full open position and the opener lights  
will flash for 5 seconds.

• Electric power to the opener.  
• A short in the white or white/black wires. These  
can occur under staples or at screw terminal  
connections.  
Plug in the opener. Green indicator lights in both  
the sending and receiving eyes will glow steadily if  
wiring connections and alignment are correct.  
• Incorrect wiring between sensors and opener.  
• An open wire (wire break).  
If the indicator light is off in the receiving eye (and  
the invisible light beam path is not obstructed),  
alignment is required.  
2. If the sending eye indicator light glows steadily but  
the receiving eye indicator light doesn't:  
• Check alignment.  
• Loosen the receiving eye wing nut to allow slight  
rotation of unit. Adjust sensor vertically and  
horizontally until the green indicator light glows

Fasten Door Bracket & Plate  
CAUTION  
To prevent damage to steel, aluminum,  
fiberglass or glass panel doors, always  
reinforce the inside of the door both vertically  
and horizontally with an angle iron.  
A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should  
cover the height of the top panel.  
The illustration 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.

Adjustment Section: Pages 21 – 23  
Adjustment Step 1  
Adjust the UP and DOWN Limits  
WARNING  
Improper adjustment of the travel limits could  
interfere with the proper operation of the  
safety reverse system. See page 23. The door  
might not reverse when required and could  
seriously injure or kill someone under it.  
Limit adjustment settings regulate the points at  
which the door will stop when moving up or down.  
The door will stop in the up direction if anything  
interferes with door travel. The door will reverse in  
the down direction if anything interferes with the  
door travel (including binding or unbalanced doors).  
To operate the opener, press the Door Control push  
button. Run the opener through a complete travel  
cycle.  
• Does the door open and close completely?  
Limit  
Adjustment  
Screws  
Left Side  
Panel  
• 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.  
Adjustment Label  
Adjustment procedures are outlined below. Run the opener through a complete travel cycle after each  
adjustment.  
Repeated operation of the opener during adjustment procedures may cause the motor to overheat and  
shut off. Simply wait 15 minutes and try again.  
Read the procedures carefully before proceeding to Adjustment Step 2. Use a screwdriver to make limit  
adjustments.  
When to Adjust the Limits  
If the door does not open completely  
but opens at least five feet  
If the opener reverses in fully closed position  
Decrease down travel. Turn the DOWN limit  
adjustment screw clockwise. One turn equals 2"  
of travel.  
Increase up travel. Turn the UP limit adjustment  
screw clockwise. One turn equals 2" of travel.  
If door does not open at least 5 feet: Adjust the  
UP (open) force as explained in Adjustment Step 2.  
If the door reverses when closing and  
there is no visible interference to travel cycle  
If the door does not close completely  
If the opener lights are flashing, the Safety Reversing  
Sensor is obstructed. Remove the obstruction.  
Increase down travel. Turn the DOWN limit  
adjustment screw counterclockwise. One turn  
equals 2" of travel.  
Test the door for binding: Pull the manual release  
handle. Manually open and close the door. If the door  
is binding, call for garage door service. If the door is  
not binding or unbalanced, adjust the DOWN (close)  
force. See Adjustment Step 2.  
If door still won't close completely, try lengthening  
the door arm. (See page 20.)  
If you have adjusted the door arm to the maximum  
length and the door still will not close completely,  
lower the header bracket. See Installation Steps 1  
and 2, pages 8 and 9.

Adjustment Step 2  
Adjust the Force  
WARNING  
Too much force on the door will interfere with  
the proper operation of the safety reverse  
system. See page 23. The door might not  
reverse properly when required and could  
seriously injure or kill someone under it. Do  
not increase the force beyond what is required  
to close the door. Do not use the force  
adjustments to compensate for a binding or  
sticking garage door.  
Force adjustment controls are located on the back  
panel of the opener. Force adjustment settings  
regulate the amount of power required to open and  
close the door.  
The door will stop in the up direction if anything  
interferes with its travel. The door will reverse in the  
down direction if anything interferes with its travel  
(including binding or unbalanced doors).  
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.  
Force Adjustment  
Controls  
The maximum force adjustment range is 260  
degrees, about 3/4 of a complete turn. Do not force  
controls beyond that point. Turn force adjustment  
controls with a screwdriver.

6. If obstructed while opening, the door will stop.  
The lockout feature prevents the trolley from  
reconnecting automatically. Pull the manual  
release handle down and back (toward the  
opener). The door can then be raised and lowered  
manually as often as necessary. To disengage the  
lockout feature, pull the manual release handle  
straight down. The trolley will reconnect on the  
next UP or DOWN operation.  
7. With the safety reversing sensor installed and  
correctly aligned, the garage door will reverse in  
the closing cycle when the invisible beam is  
broken. If fully open, the door will not close when  
the beam is broken. The sensor has no effect in  
the opening cycle.  
If the sensor is not installed, or is not aligned  
correctly, the door won't close from a remote control  
transmitter. You can close the door with the Door  
Control, however, if you press and hold the push  
button until down travel is complete. If you release  
the push button too soon, the door will reverse.

Having a Problem?  
Situation  
Probable Cause & Solution  
1. Have you disabled all door locks? Review installation instruction warnings on page 7.  
The opener doesn't  
operate from either  
the Door Control or  
a remote control:  
2. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light,  
check the fuse box or the circuit breaker. (Some outlets are controlled by a wall  
switch.)  
3. Repeated operation may have tripped the overload protector in the motor. Wait  
15 minutes. Try again.  
4. Is there a build-up of ice or snow under the door? The door may be frozen to the  
ground. Remove any restriction.  
5. Remove the bell wire from the opener terminal screws. Short the red and white  
terminals by touching both terminals at the same time with a piece of metal  
(screwdriver or coin). If the opener runs, check for a faulty wire connection at the  
door control or a short under the staples.  
Opener operates  
from a remote  
1. Are the wiring connections correct? Review Step 6, page 13.  
control, but not  
from Door Control:  
A remote control  
has short range:  
1. Check the battery test light. If the light is dim, change the battery.  
2. Change the location of the remote control in the car.  
3. A metal door, foil-backed insulation or metal garage siding will reduce the  
transmission range.  
4. Check to be sure the antenna on the back panel of opener extends fully downward.  
Install Antenna Kit, Part No. 41A3504, to increase range.  
Opener noise is  
disturbing in living  
quarters of home:  
1. If operational noise is a problem because of proximity of the opener to the living  
quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to  
eliminate the "sounding board effect" and is easy to install.  
The garage door  
opens and closes  
by itself:  
1. Check to be sure that a remote control push button is not stuck in the "down" position.  
2. Remove the bell wire from the Door Control terminals and operate from a remote  
control 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 opener.  
The door doesn't  
open completely:  
1. Is something obstructing the door?  
2. If door opens at least 5 feet, the travel limits may need to be increased. One turn  
equals 2 inches of travel. See page 21.  
Repeat the safety reverse test after the adjustment is complete.  
3. If the door has been working properly but now doesn't open all the way, increase the  
up force. See page 22.  
Repeat the safety reverse test after the adjustment is complete.  
The door doesn't  
close completely:  
1. Is something obstructing the door?  
2. Review travel limits adjustment procedures on page 21.  
Repeat the safety reverse test after any adjustment of door arm length, close  
force or down limit.

Having a Problem? (continued)  
Situation  
Probable Cause & Solution  
1. Check the safety reversing sensor. If the sensor lights do not glow, see page 18.  
The door opens but  
won't close:  
The door reverses for 1. Is something obstructing the door? Pull the red manual release handle. Operate the  
no apparent reason  
and opener light  
doesn't blink:  
door manually. If it is unbalanced or binding, call a garage door serviceman to  
correct the problem.  
2. Clear any ice or snow from the garage floor area where the door closes.  
3. Review force adjustment procedures on page 22.  
Repeat the safety reverse test after the adjustment is complete.  
4. If door reverses in the fully closed position, decrease the travel limits (page 21).  
Repeat safety reverse test after the adjustment is complete. The need for  
occasional adjustment of the force and limit settings is normal. Weather  
conditions in particular can affect door travel.  
The door reverses for  
no apparent reason  
and opener light  
1. Check the safety reversing sensor. Remove the obstruction or align the receiving  
eye. See page 18.  
blinks for 5 seconds  
after reversing:  
The opener light  
. . . doesn't turn on:  
1. Replace the light bulb (75 watts maximum). Use a "garage door opener bulb" if  
standard bulb burns out prematurely due to vibration. Vibration may be caused by  
loose end panel. Retighten the screws.  
. . . doesn't turn off:  
1. There may be a defective ground at the ceiling or wall receptacle. The unit must be  
grounded.  
The opener strains or 1. The door may be out of balance or the springs are broken. Close the door and use  
maximum force is  
needed to operate  
door:  
the manual release rope and 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  
garage door serviceman to correct the problem. Do not increase the force to  
operate the opener.  
1. The garage door springs are broken. See above.  
The opener motor  
hums briefly, then  
won't work:  
2. The trolley may be jammed into the stop bolts. Pull or push on the door while the  
motor is humming to release the jammed condition. Re-adjust the door limits (page  
21) to prevent over-travel.  
Repeat the safety reverse test after the adjustment is complete.  
3. If the problem occurs on the first operation of the opener, door may be locked.  
Disable the door lock. If the chain was removed and reinstalled, the motor may be  
out of phase. Remove the chain; cycle the motor to the down position. Observe the  
drive sprocket. When it turns in a clockwise direction and stops in the down position,  
re-install the chain.  
Repeat the safety reverse test after the adjustment is complete.  
The opener won't  
operate due to  
power failure:  
1. Use the manual release rope and handle to disconnect the trolley. The door can be  
opened and closed manually. When the power is restored, press the Door Control  
push button and trolley will automatically reconnect (unless trolley is in lockout  
position. See page 25.)  
2. 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.  
The chain droops  
or sags:  
1. It is normal for the chain to droop slightly in the closed door position. Use the manual  
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, no  
adjustments are needed (see page 7).
