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 and any

special conditions that exist and any additional

materials that may be required by referring to the lists

on page 4 or page 5.

• Spin the inner nut and lock washer down the

threaded shaft, away from the trolley.

• To tighten the chain, turn outer nut in the direction

shown.

As you turn the nut, keep the chain

from twisting.

• When the chain is approximately 1/2" above the

base of the T-rail at its midpoint, re-tighten the

inner nut to secure the adjustment.

Sprocket noise can result if chain is either too

loose or too tight.

When installation is complete, you may notice some

chain droop with the door closed. This is normal. If

the chain returns to the position shown when the

door is open,

do not re-adjust the chain.

IMPORTANT INSTALLATION INSTRUCTIONS

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

1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.

2. Install only on a properly balanced and lubricated garage door.

An improperly balanced door

may not reverse and could result in severe injury or death.

Repairs to cables, spring assemblies

and other hardware must be made by a professional service person before installing opener.

3. Disable all locks and remove all ropes connected to the garage door before installing the opener.

Ropes connected to a garage door can cause entanglement and death.

4. If possible, install door opener 7 feet or more above floor with the emergency release handle

mounted 6 feet above the floor.

5. Do not connect the opener to power source until instructed to do so.

6. 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.

7. Install the User Safety Instruction Label on the wall adjacent to the door control and the

Maintenance Instruction Label in a prominent location on the inside of the garage door.

8. Upon completion of the installation, the door must reverse when it comes in contact with a

one-inch high object or a 2x4 laid flat on the floor.

9. Do not wear watches, rings or loose clothing while installing or servicing an opener. Jewelry or

loose clothing can be caught in the mechanism of the garage door or the opener.

plate is in the way; or you can attach

it to the ceiling (refer to page 14)

when clearance is minimal. (It may

be mounted on the wall upside down

if necessary, to gain approximately

1/2".)

If you need to install the header bracket

on a 2x4 (on wall or ceiling), use lag

screws (not supplied) to securely fasten

the 2x4 to structural supports as shown

here and on page 13.

which apply to your door.

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 30).

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.

A 2x4 laid flat is convenient for setting an ideal

door-to-T-rail distance.

• Raise the opener onto a stepladder.

You will need help at this point if the ladder is

not tall enough.

• Open the door all the way and place a 2x4 laid flat

on the top section beneath the T-rail.

If the top panel hits the trolley when you raise

the door, pull down on the trolley release arm to

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.

The door control is typically attached directly to the

wall. If installing into drywall, drill 5/32" holes and use

the anchors provided.

For pre-wired installations (as

in new home construction), Console models may be

mounted to a standard single gang box (Figure 2).

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: white to 2, and

white/red to 1.

2. Pry off cover along one side with a screwdriver

blade (see Figure 1). Fasten with 6ABx1-1/4” self-

tapping screws (standard installation) or 6-32x1"

machine screws (pre-wired installation) as follows:

• Install bottom screw, allowing 1/8" to protrude

above wall surface.

• Position bottom of door control on screw head and

slide down to secure. Adjust screw for snug fit.

• Drill and install top screw with care to avoid

cracking plastic housing.

Do not overtighten.

• Insert top tabs and snap on cover.

3.

(For standard installation only)

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.

4. Connect the bell wire to the terminal screws on the

opener panel: white to 2; white/red to 1.

5. Position the antenna wire as shown.

Install the light:

• Install a 75 watt maximum light bulb in each

socket. The lights will turn ON and remain lit for

approximately 4-1/2 minutes when power is

connected. Then the lights will turn OFF.

• If the bulbs burn out prematurely due to vibration,

replace them with standard neck "Garage Door

Opener" bulbs.

Install the lens:

• Apply slight pressure on the sides of each lens

and slide the tabs into the slots in the side panels.

• For convenience, the lens may be installed

after Adjustment Step 4 on page 30.

• Reverse the procedure to remove the lenses.

Installation Step 7

Install the Light and the Lens

6. 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.

Page 32 explains how to use the door control.

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

beginning on page 21.

Installation Step 8

Attach the Emergency

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 emergency

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.

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.

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.

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.

21

The Safety Reversing System

Information you'll need before you begin the installation of the safety reversing sensor.

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 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.

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 21.

Installation Step 11

Fasten Door Bracket

Follow instructions which apply to your door

type as illustrated below or on page 25. 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 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 reinforce-

ment but does need top and bottom fastening holes

for the door bracket, fasten as shown in Figure 2.

All ONE-PIECE Doors

Assemble the Door Arm:

• Fasten the straight and curved door arm sections

together to the longest possible length, with a 2 or 3

hole overlap.

• With the door closed, connect the straight door arm

section to the door bracket with the 5/16"x1-1/4"

clevis pin.

• Secure with a ring fastener.

On one-piece doors, before connecting the door arm to the trolley the travel limits must be adjusted. Limit adjust-

ment screws are located on the left side panel as shown on page 28. Follow adjustment procedures below.

Adjustment Procedures for One-Piece Doors

Open Door Adjustment:

Decrease UP limit

• Turn the UP limit adjustment screw counter-

clockwise 5-1/2 turns.

• 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 2" of

trolley travel.

Closed Door Adjustment:

Decrease DOWN limit

• Turn the DOWN limit adjustment screw clockwise

5 complete turns.

• Press the Door Control push 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.

27

Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the

safety reversing sensors are completely

installed.

28

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?

• 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 30).

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.

equals 2" of travel.

If the door still won't close completely and the trolley

bumps into the pulley bracket (see page 4 or 5), try

lengthening the door arm (see page 26).

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 12 and 13.

• 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 23.

Test the door for binding: Pull the emergency 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 28 – 30

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 following all

adjustments to the travel limits. See page 30.

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 30.

If the door is hard to

hold or doesn't reverse, decrease the DOWN (close)

force by turning the control counterclockwise.

Make 10 degree turn 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 10 degree turn 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 10 degree turn adjustments until

door opens completely. Re-adjust 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 10 degree turn 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 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.

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.

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 26.

• 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.

Having a Problem?

Situation Probable Cause and 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 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 Step 6, page 18.

The door operates

from the Door

Control, but not from

the remote control:

1. Is any door push button flashing? If your model has the Lock feature, make sure the

lock is 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 not stuck in the “ON” position.

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 re-program all remote controls.

The door doesn't

open completely:

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

2. If the door has been working properly but now doesn't open all the way, increase the

up force.

See page 29.

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 28.

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 28.

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

force or down limit.

34

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

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

downward.

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

insulation, or metal garage siding. (Antenna Extender Kit 41A3504)

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:

1. Is something obstructing the door? Pull the red emergency 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 29.

4. If door reverses in the

fully closed

position, decrease the travel limits (page 28).

Repeat 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 door reverses for

no apparent reason

and opener lights

blink for 5 seconds

after reversing:

The opener light: . . . doesn't turn on:

Replace the light bulbs (75 watts maximum). Use a

standard neck

garage door opener

bulb if regular bulb burns out.

. . . doesn'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

emergency release 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 professional garage door serviceman.

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

.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, reinstall the chain.

Repeat the safety reverse test after the adjustment is complete.

The opener won't

operate due to

power failure:

1. Use the emergency release 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 32.

2. The Outside Trolley 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:

It is normal for the chain to droop slightly in the closed door position. Use the

emergency release to disconnect the trolley. If the chain returns to normal height when

the trolley is disengaged and the door reverses on a one-inch board, no adjustments

are needed (see page 11).

35

The door opens but

won't close:

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

See page 23.

1. If the opener lights blink, check the safety reversing sensor. See page 23.

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

See Adjustment Step 2, page 29. For an existing installation, see below.

Repeat the safety reverse test after the adjustment is complete.
