To reduce the risk of SEVERE INJURY or DEATH:

INSTALLATION STEP 1
Determine the Header Bracket Location

WARNING

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 2×4 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 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 2×4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2×4 to structural supports as shown here and on page 8.
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:
• 3″ (7.5 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 12 for ceiling installation.

INSTALLATION STEP 2
Install the Header Bracket

You can attach the header bracket either to the wall above the garage door, or to the ceiling. Follow the instructions which will work best for your particular requirements. Do not install the header bracket over drywall. If installing into masonry, use concrete anchors (not provided).

WALL HEADER BRACKET INSTALLATION
• Center the bracket on the vertical centerline with the bottom edge of the bracket on the horizontal line as shown (with the arrow pointing toward the ceiling).
• Mark the vertical set of bracket holes (do not use the holes designated for ceiling mount). Drill 3/16″ pilot holes and fasten the bracket securely to a structural support with the hardware provided.

CEILING HEADER BRACKET INSTALLATION
• Extend the vertical centerline onto the ceiling as shown.
• Center the bracket on the vertical mark, no more than 6″ (15 cm) from the wall. Make sure the arrow is pointing toward the wall. The bracket can be mounted flush against the ceiling when clearance is minimal.
• Mark the side holes. Drill 3/16″ pilot holes and fasten bracket securely to a structural support with the hardware provided.

INSTALLATION STEP 3
Attach the Rail to the Header Bracket
• Position the opener on the garage floor below the header bracket. Use packing material as a protective base. NOTE: If the door spring is in the way you’ll need help. Have someone hold the opener securely on a temporary support to allow the rail to clear the spring.
• Position the rail bracket against the header bracket.
• Align the bracket holes and join with a clevis pin as shown.
• Insert a ring fastener to secure.

INSTALLATION STEP 4
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.

WARNING

• 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.

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.

INSTALLATION STEP 5
Position the Opener
Follow instructions which apply to your door type as illustrated.
SECTIONAL DOOR OR ONE-PIECE DOOR WITH TRACK
A 2×4 laid flat is convenient for setting an ideal door-to-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 2×4 laid flat on the top section beneath the rail.
• If the top section or panel hits the trolley when you raise the door, pull down on the trolley release arm to disconnect inner and outer sections. Slide the outer trolley toward the motor unit. The trolley can remain disconnected until Installation Step 13 is completed.

CAUTION

To prevent damage to garage door, rest garage door opener rail on 2×4 placed on top section of door.

ONE-PIECE DOOR WITHOUT TRACK
A 2×4 on its side is convenient for setting an ideal door-to-rail distance.
• Remove foam packaging.
• 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 2×4 on its side on the top section of the door beneath the rail.
• The top of the door should be level with the top of the motor unit. Do not position the opener more than 4″ (10 cm) above this point.

INSTALLATION STEP 6
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), attach a sturdy metal bracket to structural supports before installing the opener. This bracket and fastening hardware are not provided. Existing brackets from a previous installation may be fastened to the sides of the motor unit as in Figures 1 and 2, or to the mounting tabs as shown in Figure 3. Then continue with step 5 below.

1. Remove foam packaging. 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″-18×1-7/8″ lag screws.
5. Fasten the opener to the hanging brackets with 5/16″-18×7/8″ hex bolts, lock washers and nuts.
If you wish to utilize the two center mounting tabs, you must triangulate the vertical brackets for additional stability (Figure 3).
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 2×4. Operate the door manually. If the door hits the rail, raise the header bracket.

WARNING

To avoid possible SERIOUS INJURY from a falling garage door opener, fasten it SECURELY to structural supports of the garage. Concrete anchors MUST be used if installing any brackets into masonry.

INSTALLATION STEP 7
Install the Door Control
Locate door control within sight of the door at a minimum height of 5 feet (1.5 m) 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 (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 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 2 and white/red wire to the 1 (Figure 3).
2. Lighted door control: Fasten to wall with 6ABx1-1/2″ self-threading screws.

Multi-function: Remove white cover by gently prying at slot in top of the cover with a small flat head screwdriver.

Fasten with 6ABx1-1/4″ self-threading screws (drywall installation) or 6-32×1″ 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. 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 13.
4. Insert all wires through the opening on top of motor unit above the terminal block on the back panel (Figure 4).
5. Strip 7/16″ (11 mm) of insulation from each set of wires. Insert door control wire into quick-connect terminals by color: white wire to white, white/red wire to red. 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 4).
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.
6. 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 Step 11 on page 18.

WARNING

To prevent possible SERIOUS INJURY or DEATH from electrocution:
• Be sure power is not connected BEFORE installing door control.
• Connect ONLY to 24 VOLT low voltage wires.
To prevent possible SERIOUS INJURY or DEATH from a closing garage door:
• Install door control within sight of garage door, out of reach of children at a minimum height of 5 feet (1.5 m), and away from all moving parts of door.
• NEVER permit children to operate or play with door control push buttons or remote control transmitters.
• Activate door ONLY when it can be seen clearly, is properly adjusted, and there are no obstructions to door travel.
• ALWAYS keep garage door in sight until completely closed. NEVER permit anyone to cross path of closing garage door.

INSTALLATION STEP 8

Install the Lights

• Install up to a 100 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.
• Insert bottom lens tabs into slots on chassis. Tilt towards chassis to engage top tabs, then drop down gently into place.
• To remove, depress both top lens tabs. Tilt lens slightly outward and down, then pull out to clear bulbs. Use care to avoid snapping off bottom lens tabs.
• Reverse the procedure to close the lens.
• If the bulbs burn out prematurely due to vibration, replace with a Garage Door Opener bulb.
  NOTE: Use only standard light bulbs. The use of short neck or speciality light bulbs may overheat the end panel or light socket.

CAUTION

To prevent possible OVERHEATING of the endpanel or light socket,
• DO NOT use short neck or specialty light bulbs.
• DO NOT use halogen bulbs. Use ONLY incandescent.

INSTALLATION STEP 9
Attach the Emergency Release Rope and Handle

• 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 at least 1″ (2.5 cm) 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 (1.83 m) above the floor. Secure with an overhand knot.
  NOTE: If it is necessary to cut the rope, heat seal the cut end with a match or lighter to prevent unraveling.

WARNING

To prevent possible SERIOUS INJURY or DEATH from a falling garage door:

• If possible, use emergency release handle to disengage trolley ONLY when garage door is CLOSED. Weak or broken springs or unbalanced door could result in an open door falling rapidly and/or unexpectedly.
• NEVER use emergency release handle unless garage doorway is clear of persons and obstructions.
• NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.

INSTALLATION STEP 10
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 until Step 11 below.

INSTALLATION STEP 11

Complete Safety Reversing Sensor Installation

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 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 the sensor vertically and/or horizontally 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 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 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 11.

INSTALLATION STEP 12
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 13.

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″-14×5/8″ 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″-14×5/8″ self-threading screws are not intended for use on wood doors.

CAUTION

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

ONE-PIECE DOORS
Please read and comply with the warnings and reinforcement instructions on the previous page.
They apply to one-piece doors also.

• Center the door bracket on the top of the door, in line with the header bracket as shown. Mark either the left and right, or the top and bottom holes.
• Metal Doors: Drill 3/16″ pilot holes and fasten the bracket with the 1/4″-14×5/8″ self-threading screws provided.
• Wood Doors: Drill 5/16″ holes and use 5/16″x2″ carriage bolts, lock washers and nuts (not provided) or 5/16″x1-1/2″ lag screws (not provided) depending on your installation needs.

NOTE: The door bracket may be installed on the top edge of the door if required for your installation. (Refer to the dotted line optional placement drawing.)

INSTALLATION STEP 13
Connect Door Arm to Trolley
Follow instructions which apply to your door type as illustrated below and on the following page.

SECTIONAL DOORS ONLY
• Make sure garage door is fully closed. Pull the emergency release handle to disconnect the outer trolley from the inner trolley. Slide the outer trolley back (away from the door) about 2″ (5 cm) as shown in Figures 1, 2 and 3.
• Figure 1:
– Fasten straight door arm section to outer trolley with the 5/16″x1″ clevis pin. Secure the connection with a ring fastener.
– Fasten curved section to the door bracket in the same way, using the 5/16″x1-1/4″ clevis pin.

• Figure 2:
– Bring arm sections together. Find two pairs of holes that line up and join sections. Select holes as far apart as possible to increase door arm rigidity.

• Figure 3, Hole alignment alternative:
– If holes in curved arm are above holes in straight arm, disconnect straight arm. Cut about 6″ (15 cm) from the solid end. Reconnect to trolley with cut end down as shown.
– Bring arm sections together.
– Find two pairs of holes that line up and join with bolts, lock washers and nuts.
• Pull the emergency release handle toward the opener at a 45° angle so that the trolley release arm is horizontal. Proceed to Adjustment Step 1, page 23. Trolley will re-engage automatically when opener is operated.

ALL ONE-PIECE DOORS
1. Assemble the door arm, Figure 4:
• 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, Figure 5:
• 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 23. Follow adjustment procedures below.
• Open door adjustment: decrease UP travel limit
– Turn the UP limit adjustment screw counter-clockwise 4 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″ (5 cm) of trolley travel.

• Closed door adjustment: decrease DOWN travel limit
– Turn the DOWN limit adjustment screw clockwise 4 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″ (5 cm) 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. 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.

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 5 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″ (5-10 m) 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 won’t 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.

WARNING

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″ (3.8 cm) high object (or 2×4 laid flat) on floor.

CAUTION

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

• 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 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 (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.

WARNING

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″ (3.8 cm) high object (or 2×4 laid flat) on floor.

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 2×4 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.

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.

WARNING

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″ (3.8 cm) high object (or 2×4 laid flat) on the floor.

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.

WARNING

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

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 won’t 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 100 watts maximum.
