ASSEMBLY HARDWARE

INSTALLATION HARDWARE

ASSEMBLY STEP 1

Assemble the Rail & Install the Trolley

To avoid installation difﬁ culties, do not run the garage door opener until instructed to do so.

The front rail has a cut out “window” at the door end (see illustration). The hole above this window is larger on the top of the rail than on the bottom. A smaller hole 3-1/2" (8.9 cm) away is close to the rail edge. Rotate the back rail so it has a similar hole close to the opposite edge, about 4-3/4" (12 cm) from the far end.

1. Remove the straight door arm and hanging bracket packaged inside the front rail and set aside for Installation Step 5 and 12.

NOTE: To prevent INJURY while unpacking the rail carefully

remove the straight door arm stored within the rail section.

2. Align the rail sections on a ﬂ at surface as shown and slide the tapered ends into the larger ones. Tabs along the side will lock into place.

To prevent INJURY from pinching, keep hands and ﬁ ngers away from the joints while assembling the rail.

3. Place the motor unit on packing material to protect the cover, and rest the back end of the rail on top. For convenience, put a support under the front end of the rail.

4. As a temporary stop, insert a screwdriver into the hole 10" (25 cm) from the front end of the rail, as shown.

5. Check to be sure there are 4 plastic wear pads inside the inner trolley. If they became loose during shipping, check all packing material. Snap them back into position as shown.

6. Slide the trolley assembly along the rail from the back end to the screwdriver.

7. Slide the rail onto the “U” bracket, until it reaches all the stops on the top and sides of the “U” bracket.

HARDWARE SHOWN ACTUAL SIZE

To avoid SERIOUS damage to garage door opener, use ONLY those bolts/fasteners mounted in the top of the opener.

ASSEMBLY STEP 3

Install the Idler Pulley

1. Lay the chain/cable beside the rail, as shown. Grasp the end of the cable and pass approximately 12" (30 cm) of cable through the window. Allow it to hang until Assembly Step 4.

2. Remove the tape from the idler pulley. The inside center should be pre-greased. If dry, regrease to ensure proper operation.

3. Place the idler pulley into the window as shown.

4. Insert the idler bolt from the top through the rail and pulley. Tighten with a 3/8" lock washer and nut underneath the rail until the lock washer is compressed.

5. Rotate the pulley to be sure it spins freely.

6. Locate the rail tab. The rail tab is between the idler bolt and the trolley in the front rail section. Use a ﬂ at head screwdriver and lift the rail tab until the tab is vertical (90°).

HARDWARE SHOWN ACTUAL SIZE

ASSEMBLY STEP 4

Install the Chain/Cable

1. Pull the cable around the idler pulley and toward the trolley.

2. Connect the cable to the retaining slot on the trolley, as shown (Figure 1):

• From below, push pins of master link bar up through cable

link and trolley slot.

• Push master link cap over pins and past pin notches.

• Slide clip-on spring over cap and onto pin notches until both

pins are securely locked in place.

3. With the trolley against the screwdriver, dispense the remainder of the cable/chain along the rail toward the motor unit into the slot on the chain spreader, around the sprocket onto the chain spreader and continuing to the trolley assembly. The sprocket teeth must engage the chain (Figure 2).

4. Check to make sure the chain is not twisted, then connect it to the threaded shaft with the remaining master link.

5. Thread the inner nut and lock washer onto the trolley threaded shaft (Figure 3).

6. Insert the trolley threaded shaft through the hole in the trolley.

Be sure the chain is not twisted (Figure 3).

7. Loosely thread the outer nut onto the trolley threaded shaft.

8. Remove the screwdriver.

To avoid possible SERIOUS INJURY to ﬁ ngers from moving garage door opener:

• ALWAYS keep hand clear of sprocket while operating opener.

• Securely attach chain spreader BEFORE operating.

Determine the Header Bracket Location

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 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 13) 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 13.

3. Open your door to the highest point of travel as shown. Draw an inter secting 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 13 for ceiling installation.

Three representative installations are shown. Yours may be different. Hanging brackets should be angled (Figure 1) to provide rigid support. On ﬁ nished 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.

NOTE: DO NOT connect power to opener at this time.

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.

Locate door control within sight of door, at a minimum height of 5 feet (1.5 m) where small children cannot reach, away from moving parts of door and door hardware. If installing into drywall, drill 5/32" holes and use the anchors provided. For pre-wired installations (as in new home construction), it may be mounted to a single gang box (Figure 1).

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 2).

2. Door Control Button: Fasten securely with 6ABx1-1/2" screws.

Console Model: Remove cover by gently prying along one side with a screwdriver (Figure 3). Fasten with 6ABx1-1/4" self-tapping screws (drywall installation) or 6-32x1" machine screws (into gang box) as follows:

• 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 ﬁ t.

• 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 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 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.

5. Position the antenna wire as shown.

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 power and operate 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.

1. Press the release tabs on both sides of lens. Gently rotate lens back and downward until the lens hinge is in the fully open position. Do not remove the lens.

2. Install a 100 watt maximum light bulb in the socket. Light bulb size should be A19, standard neck only. The light will turn ON and remain lit for approximately 4-1/2 minutes when power is connected. Then the light will turn OFF.

3. Reverse the procedure to close the lens.

4. Use A19, standard neck garage door opener bulb for replacement.

NOTE: Use only standard light bulbs. The use of short neck or speciality light bulbs may overheat the endpanel or light socket.

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. To prevent damage to the opener:

• DO NOT use bulbs larger than 100W.

• ONLY use A19 size bulbs.

INSTALLATION STEP 8

Attach the Emergency Release Rope and Handle

1. Insert one end of the emergency release rope through the handle. Make sure that “NOTICE” is right side up. Tie a knot at least 1 inch (2.5 cm) from the end of the emergency release rope.

2. Insert the other end of the emergency release rope through the hole in the trolley release arm. Mount the emergency release within reach, but at least 6 feet (1.83 m) above the ﬂ oor, avoiding contact with vehicles to prevent accidental release and secure with a knot.

NOTE: If it is necessary to cut the emergency release rope, seal the cut end with a match or lighter to prevent unraveling. Ensure the emergency release rope and handle are above the top of all vehicles to avoid entanglement.

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.

Electrical Requirements

To avoid installation difﬁ culties, 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 ﬁ t into a grounding type outlet. If the plug doesn’t ﬁ t into the outlet you have, contact a qualiﬁ ed 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:

1. Remove the motor unit cover screws and set the cover aside.

2. Remove the attached 3-prong cord.

3. 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.

4. Reinstall the cover.

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

To prevent possible SERIOUS INJURY or DEATH from electrocution or ﬁ re:

• 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 ﬁ t outlet. Be sure the opener is grounded.

Invisible Light Beam Protection Area

Safety Reversing Sensor 6" (15 cm) max. above floor

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 ﬂ ash 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 ﬂ oor. 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.

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 ﬂ oor.

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.

Facing the door from inside the garage.

INSTALLING THE BRACKETS

Wing Nut 1/4"-20

Staples (Not Shown)

Carriage Bolt 1/4"-20x1/2"

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 ﬂ oor. They may be installed in one of three ways, as follows.

Garage door track installation (preferred):

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 ﬂ ush, 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 (Figures 2 & 3):

1. 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.

2. If additional depth is needed, an extension bracket (see Accessories) or wood blocks can be used.

3. 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 ﬂ oor.

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

5. 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):

1. 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 ﬂ oor.

2. Carefully measure and place right and left assemblies at the same distance out from the wall. Be sure all door hardware obstructions are cleared.

3. Fasten to the ﬂ oor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY REVERSING SENSORS

1. 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).

2. Finger tighten the wing nuts.

3. Run the wires from both sensors to the opener. Use insulated staples to secure wire to wall and ceiling.

4. Strip 7/16" (11 mm) of insulation from each set of wires. Separate white and white/black wires sufﬁ ciently 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

1. 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 ﬂ ickering (and the invisible light beam path is not obstructed), alignment is required.

2. Loosen the sending eye wing nut and readjust, aiming directly at the receiving eye. Lock in place.

3. 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.

Figure 5

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 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. See page 20.

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 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 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.

Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE reinforcement BEFORE installation of door bracket.

Contact your door manufacturer for reinforcement kit.
