INSTALLATION STEP 1

Determine the Header Bracket Location

Installation procedures vary according to garage door types. Follow the instructions which apply to your door.

SECTIONAL DOOR AND ONE-PIECE DOOR WITH TRACK

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 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 10) 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 provided) to securely fasten the 2x4 to structural supports as shown here and on page 10.

3. Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall 2" above the high point. This height will provide travel clearance for the top edge of the door.

Proceed to Step 2, page 10.

INSTALLATION STEP 6

Install the Door Control

Locate door control within sight of the door at a minimum height of 5 feet where small children cannot reach, and away from moving parts of the door and door hardware. The installation surface must be smooth and flat. If installing into drywall (Fig. 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 (Fig. 2). NOTE: After installation, a green

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 1/4" 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 2 and white/red wire to 1 (Fig. 3).

2. Lighted door control: Fasten to wall with 6ABx1-1/2" self-tapping screws.

Multi-function door control:

Remove white cover by gently pushing both thumbs against upper corners of cover on back side of door control (Fig. 4). Fasten with 6ABx1-1/4"self-tapping screws (standard installation) or 6-32x1" machine screws (into gang box) as follows:

• Drill and 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.

• Install top screw with care to avoid

cracking plastic housing. Do not overtighten.

• Insert bottom tabs and snap on cover. (To

remove cover after mounting, gently pry at top with paper clip or small flat head screwdriver.)

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. Connect bell wire to the opener terminal screws as follows: white to 2 and white/red to 1. (Fig. 5).

5. Use tacks or staples to permanently attach entrapment warning label to wall near door control, and manual release/safety reverse test label in a prominent location on inside of garage door.

NOTE: 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 17.

INSTALLATION STEP 9

Electrical Requirements

To avoid installation difficulties, do not run the opener at this time.

To reduce the risk of electric shock, your garage door opener has a grounding type plug with a third grounding pin. This plug will only fit into a grounding type outlet. If the plug doesn't fit into the outlet you have, contact a qualified electrician to install the proper outlet.

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.

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 orange 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" 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" above garage floor.

Figure 2

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" above the floor. They may be installed in one of three ways, as follows.

Garage door track installation (preferred):

• 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:

• 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" 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:

• Use wood blocks or extension brackets (see Accessories) to elevate sensor brackets so the lenses will be no higher than 6" 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.

Figure 4MOUNTING AND WIRING THE SAFETY 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. See Figure 4.

• 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 1/4" of insulation from each set of wires. Separate white and white/black wires sufficiently to connect to the opener terminal screws: white to 2 and white/black to 3. See Figure 5.

ALIGNING THE SAFETY 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 orange 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 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 screw terminal 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 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 blink 10 times. (If bulbs are not installed, 10 clicks can be heard.) See page 17.

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" 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 doors:

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

using the self-threading screws (Figure 3).

Wood Doors:

• Use top and bottom or side to side door bracket

holes. Drill 5/16" holes through the door and secure bracket with 5/16"x2" carriage bolts, lock washers and nuts (not provided). (Figure 4)

NOTE: The 1/4"-14x5/8" self-threading screws are not intended for use on wood doors.

To prevent damage to garage door, reinforce inside of door with angle iron both vertically and horizontally.

ALL ONE-PIECE DOORS

1.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.

2.Adjustment procedures:

On one-piece doors, before connecting the door arm to the trolley, the travel limits must be adjusted. Limit adjustment screws are located on the left side panel as shown on page 24. Follow adjustment procedures below.

• 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/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 ar m does not extend far enough, adjust the limit further. One full tur n 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/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 ar m is behind the connector hole, adjust the limit further. One full tur n equals 2" of trolley travel.

3.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.

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/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 Adjustment Step 3, page 26).

Adjustment procedures are outlined below. Read the procedures carefully before proceeding to Adjustment Step 2. Use a screwdriver to make limit adjustments. Run the opener through a complete

travel cycle after each adjustment.

NOTE: Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off.Simply wait 15 minutes and try again.

NOTE: If anything interferes with the door’s upward travel, it will stop. If anything interferes with the door’s downward travel (including binding or unbalanced doors), it will reverse.

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.

NOTE: To prevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4" between the trolley and the bolt.

•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 and the trolley bumps into the pulley bracket (see page 4 or 5), try lengthening the door arm (page 22) and decreasing the down limit.

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 one-inch high object (or 2x4 laid flat) on floor.

• 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 19.

Test the door for binding: Pull the emergency release handle. Manually open and close the door.

WARNING

To prevent damage to vehicles, be sure fully open door provides adequate clearance.

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 one-inch obstruction. See Adjustment Step 3, 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.

• 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.

2.Test the UP (open) force

•Grasp the door bottom when the door is about halfway through UP (open) travel.The door should stop.If the door is hard to hold or doesn't stop, DECREASE UP (open) force by turning the control counterclockwise.Make small adjustments until the door stops easily and opens fully. After each adjustment, run the opener through a complete travel cycle.

•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.

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

ADJUSTMENT STEP 3

Test the Safety Reversal System

TEST

• With the door fully open, 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.

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 22.

• Repeat the test.

•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.

IMPORTANT SAFETY CHECK:

Repeat Adjustment Steps 1, 2 and 3 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, 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" above the floor), call for a trained door systems technician.

Without a properly installed safety reversing sensor, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

WARNING

Having a Problem?

1.The opener doesn't operate from either the Door Control or the remote control:

• 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.)

•Have you disabled all door locks? Review

installation instruction warnings on page 7.

• Is there a build-up of ice or snow under the door?

The door may be frozen to the ground.Remove any restriction.

• The garage door spring may be broken.Have it

replaced.

• Repeated operation may have tripped the overload

protector in the motor.Wait 15 minutes and tr y again.

2. Opener operates from the remote, but not from the Door Control:

• Is the door control lit? If not, remove the bell wire

from the motor unit terminals. Short the red and white terminals by touching both terminals at the same time with a piece of wire. If the opener r uns, check for a faulty wire connection at the door control, a short under the staples, or a broken wire.

• Are the wiring connections correct? Review

Installation Step 6, page 14.

3.The door operates from the Door Control, but not from the remote control:

• Is the door push bar flashing? If your model has

the Lock feature, make sure it is off.

• Program the opener to match the remote control

code. (Refer to instructions on the motor unit panel.) Repeat with all remotes.

4.The remote control has short range:

• Change the location of the remote control in your

car.

• Check to be sure the antenna on the side or back

panel of motor unit extends fully downward.

• Some installations may have shor ter range due to

a metal door, foil backed insulation, or metal garage siding.

5. 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.

WARNING

Page 30

Having a Problem? (Continued)

6.The garage door opens and closes by itself:

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

•Remove the bell wire from the door control terminals and operate from the remote 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 motor unit.

•Clear memory and re-program all remote controls.

7.The door doesn't open completely:

• Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or repair the door.

•If the door is in good working order but now

doesn't open all the way, increase the up force. See Adjustment Step 2.

• If the door opens at least 5 feet, the travel limits may need to be increased. One turn equals 2 inches of travel.See Adjustment Step 1.

Repeat the safety reverse test after the adjustment is complete.

8.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.

9.The door opens but won't close:

• If the opener lights blink, check the safety reversing sensor. See Installation Step 10.

• If the opener lights don’t 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.

10.The door reverses for no apparent reason and

opener lights don’t blink:

• Is something obstructing the door? Pull the emergency release handle. Operate the door manually. If it is unbalanced or binding, call a trained door systems technician.

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

•Review Adjustment Step 2 on page 25.

• If door reverses in the fully closed position, decrease the travel limits (Adjustment Step 1).

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.

11.The door reverses for no apparent reason and opener lights blink for 5 seconds after reversing:

• Check the safety reversing sensor.Remove any

obstruction or align the receiving eye.See

Installation Step 10.

12.The opener lights don't turn on:

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

standard neck garage door opener bulb if regular bulb burns out.

13.The opener lights don't turn off:

• Is the Light feature on? Turn it off.

14.The opener strains or maximum force is needed to operate door:

•The door may be out of balance or the springs

may be broken.Close the door and use the emergency 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 a trained door systems technician. Do not increase

the force to operate the opener.

15.The opener motor hums briefly, then won't work:

• The garage door springs may be broken.See

above.

• 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.

16.The opener won't operate due to power failure:

• Use the emergency release handle to disconnect

the trolley. The door can be opened and closed manually.When power is restored, press the Door Control push bar and trolley will automatically reconnect (unless trolley is in lockout position.) See page 28.

• 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.

17.The chain droops or sags:

• It is normal for the chain to droop slightly in the

closed door position. Use the emergency 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 laid flat, no adjustments are needed. (See page 7.)
