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' (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.

On finished ceilings (Figures 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.

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, 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 2).

NOTE: The functional temperature range of the door control is between -4° F (-20° C) and 122° F (50° C). Scroll speed of display is slower at lower temperatures although the door control remains fully functional.

CAUTION: Continuous exposure of the door control to temperatures below -22° F (-30° C) may damage the LCD screen.

SPECIAL NOTE: Only one Smart Control Panel® can be connected to each garage door opener. If additional wall controls are desired to operate the same garage door opener, it is recommended to use model 41A6345-1 wireless wall control as the secondary door control.

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 W (2) and white/red wire to the R (1).

2. Remove cover by gently prying at slot in top of the cover with a small flat head screwdriver. 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 fit.

• Drill and install top screw with care to avoid cracking plastic

housing. DO NOT overtighten.

• Insert top tabs and snap on cover.

3. (For standard installation only) Run 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.

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.

To prevent possible SERIOUS INJURY or DEATH from electrocution:

• Disconnect ALL electric and battery power BEFORE performing ANY service or maintenance.

• 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 controls.

• 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.

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:

• Disconnect ALL electric and battery power BEFORE performing ANY service or maintenance.

• 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 11

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.

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.

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):

• 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 (Figures 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.

Red GreyWhite

• 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.

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 21.

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"-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.
