WARNING WARNING

CAUTIONCAUTION

Contents

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!

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.

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.

Operation at other than 120V 60 Hz will cause opener

malfunction and damage.

Identify the type and height of your door, any special

conditions that exist, and any additional materials that

may be required.

Test Your Door for Balance

Before you begin, complete the following test to make

sure your door is balanced, and is not sticking or

binding:

• 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.

• Insert a ring fastener to secure.

Installation Step 3

Attach the Rail to the Header Bracket

Hardware Shown Actual Size

The safety reversing sensor must be connected and

aligned correctly before the garage door opener will

move in the down direction. This is a required safety

device and cannot be disabled.

Installation procedures are the same for sectional and

one-piece doors.

Be sure power to the opener is disconnected.

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.

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.

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.

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 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.

Without a properly working safety reversing sensor,

persons (particularly children) could be injured or 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.

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).

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.

Install Door Control

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.

1. Strip 1/4" of insulation from one end of the bell wire

and connect it to the two screw terminals on the back

of the door control by color: white to 2 and white/red

to 1 (see Figure 1).

2. Fasten the Multi-Function Door Control uses

6ABx1-1/4" screws. If installing into drywall, drill

5/32" holes and use the anchors provided.

3. 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, creating a short. If your access door is near the

garage door, you may run this wire with the Safety

Reversing Sensor wires along the top of the rail. See

page 14.

4. Remove the Control Center door on the right panel of

the opener to access the terminal screws.

Connect Door Control and Sensor Wiring

5. Thread all wires through the opening at the base of the

drive shaft cover (see Figure 2).

6. Insert the remaining wire through the hole in the power

unit and strip 1/4" of insulation from each set of wires.

7. Connect the door control wire to the opener terminal

screws: white to 2 and white/red to 1. (See Figure 3.)

8. Separate the sensor white and white/black wires

sufficiently to connect to the opener terminal screws:

white to 2 and white/black to 3.

9. Attach 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

To make a permanent connection through the 7/8" diam.

hole in the top of the opener (according to local code):

• 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.

• Reinstall the cover.

To prevent electrocution or fire,

installation and wiring

must be in compliance with local electrical and building

codes.

Do NOT use an extension cord, 2-wire adapter, or change

the plug in any way to make it fit your outlet.

To avoid installation difficulties,

do not run the opener until Step 9 below.

To prevent electrocution,

remove power from the

garage door opener

and

from the circuit you plan to

use for the permanent connection.

WARNING

Installation Step 9

Complete Safety Reversing Sensor

Installation

Aligning the Safety Sensors

• Plug in the opener. Green indicator lights in both the

sending and receiving eyes will glow steadily if wiring

connections and alignment are correct.

The sending eye indicator light will glow regardless of

alignment or obstruction. If the indicator light is off, dim,

or flickering in the receiving eye (and the invisible light

beam path is not obstructed), alignment is required.

• Loosen the sending eye wing nut and re-adjust, aiming

directly at the receiving eye. Lock in place.

• Loosen the receiving eye wing nut and adjust sensor

vertically and/or horizontally until it receives the

sender’s beam. When the green indicator light glows

steadily, tighten the wing nut.

Trouble Shooting

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 under staples or at screw terminal connections.

• Incorrect wiring between sensors and opener.

• An open wire (wire break).

2. If the sending eye indicator light glows steadily but

the receiving eye indicator light doesn't:

• 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 flash 10 times. (If bulbs are not

installed, 10 clicks are audible.) See page 12.

Installation Step 10

Install the Lights and Lens

Installation Step 11

Attach the Manual Release

Rope and Handle

Do not use the red handle to pull the door open or

closed.

The rope knot could become untied and you

could fall.

Use the manual release only to disengage the

trolley and, if possible, only when the door is closed.

Garage doors are heavy. If the door is open when the

handle is pulled, the door could close inadvertently if it is

not properly balanced. Serious injury may result to

persons under the door. Make sure the doorway is clear

of persons and obstructions before pulling handle when

door is open.

• 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.

The knot should be at least 1" 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 above the

floor. Secure with an overhand knot .

If it is necessary to cut the rope, heat seal the cut end

with a match or lighter to prevent unraveling.

Fasten Door Bracket

Follow instructions which apply to your door type

as illustrated below or on page 21.

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.

• Center the door bracket on the previously marked

vertical guideline used for the header bracket

installation. Note the correct UP placement, as

stamped inside the bracket.

• Position the bracket on the face of the door within the

following limits:

A) The top edge of the bracket 2-4" below the top edge

of the door.

B) The top edge of the bracket directly below any

structural support across the top of the door.

• Mark and drill 5/16" left and right fastening holes.

Secure the bracket as shown in Figure 1 if there is

vertical reinforcement.

If your installation doesn't require vertical reinforcement

but does need top and bottom fastening holes for the door

bracket, fasten as shown in Figure 2.

Adjustment Procedures for One-Piece Doors

Open Door Adjustment:

Decrease UP Travel Limit

• Turn the UP limit adjustment screw counter-clockwise

5 1/2 turns.

• Press the Door Control push bar or 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 2" of trolley travel.

Closed Door Adjustment:

Decrease DOWN Travel Limit

• Turn the DOWN limit adjustment screw clockwise

5 complete turns.

• Press the Door Control push bar or button. The trolley

will travel to the fully closed position.

• 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" of trolley travel.

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.

• 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.

Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the safety

reversing sensors are completely installed.

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 bar.

Run the opener through a complete travel cycle.

• 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

(see page 26).

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.

How and When to Adjust the Limits

If the door does not open completely but opens at least

five feet:

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 does not close completely:

Increase down travel. Turn the DOWN limit adjustment

screw counterclockwise. One turn equals 2" of travel.

If door still won't close completely, try lengthening the

door arm. (Page 22.)

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 Step 1, pages 8/9.

If the opener reverses in fully closed position:

Decrease down travel. Turn the DOWN limit adjustment

screw clockwise. One turn equals 2" 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 18.

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.

Adjustment Section: Pages 24 – 26

Improper adjustment of the travel limits will interfere with

the proper operation of the safety reverse system.

The

door might not reverse properly when required and could

seriously injure or kill someone under it.

Test the safety

reverse system monthly, and following all adjustments to

the travel limits. See page 26.

How and When to Adjust the Forces

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

page 26. 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.

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. After

each adjustment, run the opener through a complete

travel cycle.

If the door doesn't open at least 5 feet:

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.

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.

WARNING

Force adjustment controls are located on the right 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.

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.

Adjustment Step 4

Test the Safety Reverse System

Test

• Place a one-inch board (or a 2x4 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.

Adjustment

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.

• Repeat the test.

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 22.

• When the door reverses on the one-inch board, remove

the obstruction and run the opener through 3 or 4

complete travel cycles to test adjustment.

If the door will not reverse after repeated adjustment

attempts, call for professional garage door service.

Important Safety Check

Repeat Adjustment Steps 1-4 after:

• Each adjustment of door arm length, force controls or

limit 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.

1 Inch Obstruction

Failure to test and adjust the safety reverse system may

result in serious injury or death to persons trapped by a

closing garage door.

Repeat this test once a month and

adjust as needed.

Adjustment Step 3

Test The Protector System

• 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, and the

opener light will flash for 5 seconds.

Professional service is required if the opener closes the

door when the safety reversing sensor is obstructed.

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).

The garage door can be closed by pressing and holding the

Door Control push bar until down travel is completed.

Safety Reversing Sensor Safety Reversing Sensor

Repeat the safety reverse test. Make any necessary

adjustments (See page 26).

Once a Year

Oil door rollers, bearings and hinges. The opener does

not require additional lubrication. Do not grease the door

tracks.

Weather conditions may cause some minor changes in

door operation requiring some re-adjustments,

particularly during the first year of operation.

Pages 24 and 25 refer to the limit and force adjustments.

Only a screwdriver is required. Follow the instructions

carefully.

Repeat the safety reverse test (page 26) after any

adjustment of limits or force.

Care of Your Opener

IMPORTANT SAFETY INSTRUCTIONS

To reduce the risk of severe injury or death to persons:

1. READ AND FOLLOW ALL INSTRUCTIONS.

2. Do not permit children either to operate or to play with the opener. Keep remote control in a location

inaccessible to children.

3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in sight

until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.

4. Check safety reversal system monthly. See page 26. The garage door MUST reverse on contact with a one

inch object (or a 2x4 board laid flat) placed on the floor. If an adjustment is made to one of the controls

(either force or limits of travel), the other control may need to be adjusted also, and the safety reversal

system must be checked. Failure to properly adjust the opener may result in severe injury or death.

5. If possible, use the manual release only when the door is in a closed position. Caution should be taken

whenever the disconnect cord is actuated with the door open. Weak or broken springs may cause the door to

fall rapidly, causing injury or death to persons.

6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 3. An improperly balanced door may not

reverse when required, and could result in severe injury or death. Repairs to cables, spring assemblies and

other hardware must be made by a professional garage door person.

7. Disconnect the electric power to the garage door opener before making any repairs or removing the covers.

Operation of the Multi-Function Door Control

(See additional programming features, next page.)

To open the door manually:

The door should be fully

closed if possible. Pull down

on the manual release handle

(so that the trolley release arm

snaps into a vertical position)

and lift the door manually. The

lockout feature prevents the

trolley from reconnecting auto-

matically, and the door can be

raised and lowered manually as

often as necessary.

To reengage the trolley: Pull

the manual release handle

toward the opener at a 45

degree angle so that the trolley

release arm is horizontal. The

trolley will reconnect on the

next UP or DOWN operation,

either manually or by pressing

the Door Control push bar.

1. 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.)

2. Have you disabled all door locks? Review installation instruction warnings on Page 7.

3. Is there a build-up of ice or snow under the door? The door may be frozen to the ground.

Remove any restriction.

4. The garage door spring may be broken. Have it replaced.

Having a Problem?

Situation Probable Cause & Solution

The opener doesn't

operate from either

the door control or

the remote control:

Opener operates from

the remote control, but

not from the door

control:

1. Is the door control push bar lit? If not, 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 wire. If the opener runs, check for a faulty wire connection at the door control, a

short under the staples, or a broken wire.

2. Are the wiring connections correct? Review Installation Step 7, page 17.

The door operates from

the door control, but not

from the remote

control:

1. Is the door push bar flashing? If your model has the Lock feature, turn it off.

2. Your opener needs to re-learn a remote control code. Refer to instructions on the opener

panel.

3. Program the receiver to match the remote control code.

4. Repeat the receiver programming procedure with all remote controls.

The remote control has

short range:

The garage door

opens and closes by

itself:

1. Be sure that all remote control push buttons are off.

2. Remove the bell wire from the door control terminals and operate from the 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.

3. Clear memory and reprogram all remote controls.

The door doesn't open

completely: 1. If the door has been working properly but now doesn't open all the way, increase the up

force. See page 25.

2. Is something obstructing the door? Remove the obstruction or repair the door.

3. If door opens at least 5 feet, the travel limits may need to be increased. One turn equals

2 inches of travel. See page 24.

Repeat the safety reverse test after the adjustment is complete.

The door stops but

doesn't close

completely:

Review the travel limits adjustment procedures on page 24.

Repeat the safety reverse test after any adjustment of door arm length, close force or down

limit.

1. Change the location of the remote control in your car.

2. Check to be sure the antenna on the right side panel of opener extends fully.

3. Some installations may have shorter range due to a metal door, foil backed insulation, or

metal garage siding.

Opener noise is

disturbing in living

quarters of home:

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 minimize vibration

to the house and is easy to install.

Having a Problem?

(continued)

Situation Probable Cause & Solution

The door reverses for no

apparent reason and

opener lights don't

blink:

The door reverses for no

apparent reason and

opener lights blink for

5 seconds after

reversing:

1. Is something obstructing the door? Pull the manual release handle. Operate the door

manually. If it is unbalanced or binding, call for professional garage door service.

2. Clear any ice or snow from the garage floor area where the door closes.

3. Review the force adjustment procedures on page 25.

4. If door reverses in the fully closed position, decrease the travel limits (page 24).

Repeat the 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.

The opener lights… don't turn on:

Replace the light bulb(s) (100 watts maximum). Use a standard neck garage door opener bulb

if regular bulb burns out.

don't turn off:

Is the Light feature on? Turn it off.

The opener strains or

maximum force is

needed to operate door:

The door may be out of balance or the springs are broken. Close the door and use the manual

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 for professional garage door service. Do not

increase the force to operate the opener.

The opener motor

hums briefly, then

won't work:

1. The garage door springs are broken. See above.

2. If the problem occurs on the first operation of the opener, door may be locked. Disable the

door lock.

Repeat the safety reverse test after the adjustment is complete.

The opener won't

operate due to power

failure:

1. Use the manual release handle to disconnect the trolley. The door can be opened and closed

manually. When power is restored, press the Door Control push bar or button and trolley

will automatically reconnect (unless trolley is in lockout position.) See page 28.

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 door opens but

won't close: 1. If the opener lights blink, check the safety reversing sensor. See page 18.

2. If the opener lights do not blink and it is a new installation, check the down force. See

Adjustment Step 2, page 25. For an existing installation, see below.

Repeat the safety reverse test after the adjustment is complete.

Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See

page 18.
