INSTALLATION STEP 1

Determine the Header Bracket

Location

Installation procedures vary according to garage door

types. Follow the instructions which apply to your door.

1. Close the door and mark the inside vertical centerline of

the garage door.

2. Extend the line onto the header wall above the door.

You can fasten the header bracket within 4 feet

(1.22 m) of the left or right of the door center only if

a torsion spring or center bearing plate is in the

way; or you can attach it to the ceiling (see page 9)

when clearance is minimal. It may be mounted on

the wall upside down if necessary, to gain

approximately 1/2" (1 cm).

If you need to install the header bracket on a 2x4

(on wall or ceiling), use lag screws (not provided)

to securely fasten the 2x4 to structural supports as

shown here and on page 9.

3. Open your door to the highest point of travel as shown.

Draw an intersecting horizontal line on the header wall

above the high point:

• 2" (5 cm) above the high point for sectional door and

one-piece door with track.

• 8" (20 cm) above the high point for one-piece door

without track.

This height will provide travel clearance for the top edge

of the door.

NOTE: If the total number of inches exceeds the height

available in your garage, use the maximum height

possible, or refer to page 9 for ceiling installation.

To prevent possible SERIOUS INJURY or DEATH:

• Header bracket MUST be RIGIDLY fastened to structural

support on header wall or ceiling, otherwise garage door

might not reverse when required. DO NOT install header

bracket over drywall.

• Concrete anchors MUST be used if mounting header bracket

or 2x4 into masonry.

• NEVER try to loosen, move or adjust garage door, springs,

cables, pulleys, brackets, or their hardware, ALL of which

are under EXTREME tension.

• ALWAYS call a trained door systems technician if garage

door binds, sticks, or is out of balance. An unbalanced

garage door might not reverse when required.

INSTALLATION STEP 5

Hang the Opener

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.

1. Measure the distance from each side of the motor unit

to the structural support.

2. Cut both pieces of the hanging bracket to required

lengths.

3. Drill 3/16" pilot holes in the structural supports.

4. Attach one end of each bracket to a support with

5/16"-18x1-7/8" lag screws.

5. Fasten the opener to the hanging brackets with

5/16"-18x7/8" hex bolts, lock washers and nuts.

6. Check to make sure the rail is centered over the door

(or in line with the header bracket if the bracket is not

centered above the door).

7. Remove the 2x4. Operate the door manually. If the door

hits the rail, raise the header bracket.

8. Grease the top and underside of the rail surface where

the trolley slides with rail grease.

CAUTION WARNING

WARNING

INSTALLATION STEP 6

Install the Door Control

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 the top of the

cover with a small flat head screwdriver (Figure 4).

Fasten with 6ABx1-1/4" self-tapping screws (drywall

installation) or 6-32x1" machine screws (into gang box)

as follows:

• Drill and install bottom screw, allowing 1/8"(3 mm) to

protrude above wall surface.

• Position bottom of door control on screw head and

slide down to secure. Adjust screw for snug fit.

• Install top screw with care to avoid cracking plastic

housing. Do not overtighten.

• Insert bottom tabs and snap on cover.

NOTE: The push bar may stick if the door control is not

mounted on a smooth surface. If a click is not heard

when pressing the push bar, loosen the two mounting

screws or relocate the door control to a smoother

surface.

3. (Standard installation only) Run bell wire up wall and

across ceiling to motor unit. Use insulated staples to

secure wire in several places. Do not pierce wire with a

staple, creating a short or open circuit.

4. Strip 7/16" (11 mm) of insulation from end of bell wire.

Connect bell wire to the quick-connect terminals as

follows: white to white and white/red to red (Figure 5).

NOTE: When connecting multiple door controls to the

opener, twist same color wires together. Insert wires into

quick-connect holes: white to white and red/white to red.

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 does not fit into the outlet you have, contact a

qualified electrician to install the proper outlet.

If permanent wiring is required by your local code,

refer to the following procedure.

To make a permanent connection through the 7/8" hole in

the top of the motor unit:

• Remove the motor unit 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 avoid installation difficulties, do not run the opener

at this time.

RIGHT WRONG

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.

The mounting brackets are designed to clip onto the track

of sectional garage doors without additional hardware.

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.

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.

INSTALLING THE BRACKETS

Be sure power to the opener is disconnected. Install

and align the brackets so the sensors will face each other

across the garage door, with the beam no higher than 6"

(15 cm) above the floor. They may be installed in one of

three ways, as follows.

Garage door track installation (preferred) (Figure 1):

• Slip the curved arms over the rounded edge of each

door track, with the curved arms facing the door. Snap

into place against the side of the track. It should lie

flush, with the lip hugging the back edge of the track, as

shown in Figure 1.

If your door track will not support the bracket securely, wall

installation is recommended.

Wall installation (Figure 2 & 3):

• Place the bracket against the wall with curved arms

facing the door. Be sure there is enough clearance for

the sensor beam to be unobstructed.

• If additional depth is needed, an extension bracket

(see Accessories) or wood blocks can be used.

• Use bracket mounting holes as a template to locate and

drill (2) 3/16" diameter pilot holes on the wall at each

side of the door, no higher than 6" (15 cm) above the

floor.

• Attach brackets to wall with lag screws (not provided).

• If using extension brackets or wood blocks, adjust right

and left assemblies to the same distance out from the

mounting surface. Make sure all door hardware

obstructions are cleared.

Floor installation (Figure 4):

• Use wood blocks or extension brackets

(see Accessories) to elevate sensor brackets so the

lenses will be no higher than 6" (15 cm) above the floor.

• Carefully measure and place right and left assemblies at

the same distance out from the wall. Be sure all door

hardware obstructions are cleared.

• Fasten to the floor with concrete anchors as shown.

SENSORS

• Slide a 1/4"-20x1/2" carriage bolt head into the slot on

each sensor. Use wing nuts to fasten sensors to

brackets, with lenses pointing toward each other across

the door. Be sure the lens is not obstructed by a bracket

extension (Figure 5).

• Finger tighten the wing nuts.

•Run the wires from both sensors to the opener. Use

insulated staples to secure wire to wall and ceiling.

• Strip 7/16" (11 mm) of insulation from each set of wires.

Separate white and white/black wires sufficiently to

connect to the opener quick-connect terminals. Twist

like colored wires together. Insert wires into

quick-connect holes: white to white and white/black to

grey (Figure 6).

ALIGNING THE SAFETY REVERSING SENSORS

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

sending and receiving eyes will glow steadily if wiring

connections and alignment are correct.

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.

• Loosen the sending eye wing nut and readjust, aiming

directly at the receiving eye. Lock in place.

• 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.

TROUBLESHOOTING THE SAFETY REVERSING

SENSORS

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 at staples, or at opener connections.

• Incorrect wiring between sensors and opener.

• A broken wire.

2. If the sending eye indicator light glows steadily but the

receiving eye indicator light does not:

• 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 16.

WARNING

CAUTION WARNING

WARNING

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.

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.

SECTIONAL DOORS

1. Center the door bracket on the previously marked

vertical centerline used for the header bracket

installation. Note correct UP placement, as stamped

inside the bracket.

2. Position the top edge of the bracket 2"-4" (5-10 cm)

below the top edge of the door, OR directly below any

structural support across the top of the door.

3. Mark, drill holes and install as follows, depending on

your door’s construction:

Metal or light weight doors using a vertical angle iron

brace between the door panel support and the door

bracket:

• Drill 3/16" fastening holes. Secure the door bracket

using the two 1/4"-14x5/8" self-threading screws

(Figure 2A).

• Alternately, use two 5/16" bolts, lock washers and nuts

(not provided) (Figure 2B).

Metal, insulated or light weight factory reinforced

• 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.

NOTE: When setting the up limit on the following page, the

door should not have a “backward” slant when fully open

as illustrated below. A slight backward slant will cause

unnecessary bucking and/or jerking operation as the door

is being opened or closed from the fully open position.

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.

• 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 25).

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. 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.

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 2" (5 cm) of travel.

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):

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" (5 cm) of

travel.

If door still will not close completely and the trolley

bumps into the pulley bracket (page 4), try lengthening

the door arm (page 21) and decreasing the down limit.

• If the opener reverses in fully closed position:

Decrease down travel. Turn the down limit adjustment

screw clockwise. One turn equals 2" (5 cm) of travel.

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.

• 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 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.

ADJUSTMENT STEP 2

Adjust the Force

Force adjustment controls are located on the back panel

of the motor unit. Force adjustment settings regulate the

amount of power required to open and close the door.

If the forces are set too light, door travel may be

interrupted by nuisance reversals in the down direction

and stops in the up direction. Weather conditions can

affect the door movement, so occasional adjustment may

be needed.

The maximum force adjustment range is about 3/4 of a

complete turn. Do not force controls beyond that

point. Turn force adjustment controls with a screwdriver.

NOTE: If anything interferes with the door’s upward travel,

it will stop. If anything interferes with the door’s downward

travel (including binding or unbalanced doors), it will

reverse.

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 25. If the door is hard to

hold or does not 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.

• If the door reverses during the down (close) cycle

and the opener lights are not 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.

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 does not stop, DECREASE

UP (open) force by turning the control counterclockwise.

Make small adjustments until the door stops easily and

opens fully. After each adjustment, run the opener

through a complete travel cycle.

• If the door does not 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.

24

Without a properly installed safety reversal system, persons

(particularly small children) could be SERIOUSLY INJURED or

KILLED by a closing garage door.

• Too much force on garage door will interfere with proper

operation of safety reversal system.

• 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.

• 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.

Without a properly installed safety reversal system, persons

(particularly small children) could be SERIOUSLY INJURED or

KILLED by a closing garage door.

• Safety reversal system MUST be tested every month.

• 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.

25

ADJUSTMENT STEP 3

Test the Safety Reversal System

TEST

• 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.

• Operate the door in the down direction. The door must

reverse on striking the obstruction.

ADJUST

• If the door stops on the obstruction, it is not traveling far

enough in the down direction. Increase the DOWN 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 21.

• 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.

ADJUSTMENT STEP 4

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 (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.

To reduce the risk of SEVERE INJURY or DEATH:

Using Your Garage Door Opener

Your Security✚®opener and hand-held remote control

have been factory-set to a matching code which changes

with each use, randomly accessing over 100 billion new

codes. Your opener will operate with up to eight Security✚®

remote controls and one Security✚®Keyless Entry System.

If you purchase a new remote, or if you wish to deactivate

any remote, follow the instructions in the Programming

section.

Activate your opener with any of the following:

•The hand-held Remote Control: Hold the large push

button down until the door starts to move.

•The wall-mounted Door Control: Hold the push button or

bar down until the door starts to move.

•The Keyless Entry (See Accessories): If provided with

your garage door opener, it must be programmed before

use. See Programming.

When the opener is activated (with the safety

reversing sensor correctly installed and aligned)

1. If open, the door will close. If closed, it will open.

2. If closing, the door will reverse.

3. If opening, the door will stop.

4. If the door has been stopped in a partially open position,

it will close.

5. If obstructed while closing, the door will reverse. If the

obstruction interrupts the sensor beam, the opener lights

will blink for five seconds.

6. If obstructed while opening, the door will stop.

7. 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 misaligned, the door will

not close from a hand-held remote. However, you can

close the door with the Door Control, the Outside Keylock,

or Keyless Entry, if you activate them until down travel is

complete. If you release them too soon, the door will

reverse.

The opener lights will turn on under the following

conditions: when the opener is initially plugged in; when

power is restored after interruption; when the opener is

activated.

They will turn off automatically after 4-1/2 minutes or

provide constant light when the Light feature on the

Multi-Function Door Control is activated. Bulb size is A19.

Bulb power is 100 watts maximum.

not apply to you. THIS LIMITED WARRANTY DOES NOT COVER NON-DEFECT DAMAGE, DAMAGE CAUSED BY IMPROPER

AND NECESSARY MAINTENANCE, UNAUTHORIZED REPAIRS OR ANY ALTERATIONS TO THIS PRODUCT), LABOR CHARGES FOR
