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 9) when clearance is minimal. (It may be
mounted on the wall upside down if necessary, to gain
approximately 1/2" (1 cm).)
If you need to install the header bracket on a 2x4 (on wall or
ceiling), use lag screws (not provided) to securely fasten the
2x4 to structural supports as shown here and on page 9.
3. Open your door to the highest point of travel as shown. Draw
an 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 9 for ceiling installation.

INSTALLATION STEP 5
Hang the Opener
Three representative installations are shown. Yours may be
different. Hanging brackets should be angled (Figure 1) to provide
rigid support. On finished ceilings (Figure 2 and Figure 3), attach
a sturdy metal bracket to structural supports before installing the
opener. This bracket and fastening hardware are not provided.
1. Measure the distance from each side of the motor unit to the
structural support.
2. Cut both pieces of the hanging bracket to required lengths.
3. Drill 3/16" pilot holes in the structural supports.
4. Attach one end of each bracket to a support with
5/16"-18x1-7/8" lag screws.
5. Fasten the opener to the hanging brackets with
5/16"-18x7/8" hex bolts, lock washers and nuts.
6. Check to make sure the rail is centered over the door (or in line
with the header bracket if the bracket is not centered above the
door).
7. Remove the 2x4. Operate the door manually. If the door hits
the rail, raise the header bracket.
8. Grease the top and underside of the rail surface where the
trolley slides with rail grease.
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, and away from
moving parts of door and door hardware. The installation surface
must be smooth and flat. If installing into drywall (Figure 1), drill
5/32" holes and use anchors provided. For pre-wired installations
(as in new home construction), it may be mounted to a single
gang box (Figure 2).
NOTE: After installation, a green or amber indicator light behind
the cover will indicate proper connection. If not lit, the Lock and
Light features will not function (reverse wires to correct).
1. Strip 7/16" (11 mm) of insulation from one end of bell wire and
connect to the two screw terminals on back of door control by
color: white wire to WHT and white/red wire to the RED
(Figure 3).
2. Remove cover by gently prying at slot in the top of the cover
with a small flat head screwdriver (Figure 4). Fasten with
6ABx1-1/4" self-tapping screws (drywall installation) or
6-32x1" machine screws (into gang box) as follows:
• Drill and install bottom screw, allowing 1/8"(3 mm) to
protrude above wall surface.
• Position bottom of door control on screw head and slide
down to secure. Adjust screw for snug fit.
• Install top screw with care to avoid cracking plastic housing.
Do not overtighten.
• Insert bottom tabs and snap on cover.
NOTE: The push bar may stick if the door control is not
mounted on a smooth surface. If a click is not heard when
pressing the push bar, loosen the two mounting screws or
relocate the door control to a smoother surface.
3. (Standard installation only) Run bell wire up wall and across
ceiling to motor unit. Use insulated staples to secure wire in
several places. Do not pierce wire with a staple, creating a
short or open circuit.
4. Strip 7/16" (11 mm) of insulation from end of bell wire.
Connect bell wire to the quick-connect terminals as follows:
white to white and white/red to red (Figure 5).
NOTE: When connecting multiple door controls to the opener,
twist same color wires together. Insert wires into quick-connect
holes: white to white and red/white to red.
5. Use tacks or staples to permanently attach entrapment warning
label to wall near door control, and manual release/safety

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 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.
Facing the door from inside the garage.

INSTALLING THE BRACKETS
Be sure power to the opener is disconnected. Install and align
the brackets so the sensors will face each other across the garage
door, with the beam no higher than 6" (15 cm) above the floor.
They may be installed in one of three ways, as follows.
Garage door track installation (preferred) (Figure 1):
• Slip the curved arms over the rounded edge of each door track,
with the curved arms facing the door. Snap into place against
the side of the track. It should lie flush, with the lip hugging the
back edge of the track, as shown in Figure 1.
If your door track will not support the bracket securely, wall
installation is recommended.
Wall installation (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.

MOUNTING AND WIRING THE SAFETY REVERSING SENSORS
• Slide a 1/4"-20x1/2" carriage bolt head into the slot on each
sensor. Use wing nuts to fasten sensors to brackets, with
lenses pointing toward each other across the door. Be sure the
lens is not obstructed by a bracket extension (Figure 5).
• Finger tighten the wing nuts.
• Run the wires from both sensors to the opener. Use insulated
staples to secure wire to wall and ceiling.
• Strip 7/16" (11 mm) of insulation from each set of wires.
Separate white and white/black wires sufficiently to connect to
the opener quick-connect terminals. Twist like colored wires
together. Insert wires into quick-connect holes: white to white
and white/black to grey (Figure 6).
ALIGNING THE SAFETY REVERSING SENSORS
• Plug in the opener. The indicator lights in both the sending and
receiving eyes will glow steadily if wiring connections and
alignment are correct.
The sending eye amber indicator light will glow regardless of
alignment or obstruction. If the green indicator light in the
receiving eye is off, dim, or flickering (and the invisible light beam
path is not obstructed), alignment is required.
• Loosen the sending eye wing nut and readjust, aiming directly
at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust sensor until it
receives the sender’s beam. When the green indicator light
glows steadily, tighten the wing nut.
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 16.

Follow instructions which apply to your door type as illustrated
below or on the following page.
A horizontal reinforcement brace should be long enough to be
secured to two or three vertical supports. A vertical
reinforcement brace should cover the height of the top panel.
Figure 1 shows one piece of angle iron as the horizontal brace.
For the vertical brace, 2 pieces of angle iron are used to create
a U-shaped support. The best solution is to check with your
garage door manufacturer for an opener installation door
reinforcement kit.
NOTE: Many door reinforcement kits provide for direct
attachment of the clevis pin and door arm. In this case you will
not need the door bracket; proceed to Step 12.
SECTIONAL DOORS
1. Center the door bracket on the previously marked vertical
centerline used for the header bracket installation. Note correct
UP placement, as stamped inside the bracket.
2. Position the top edge of the bracket 2"-4" (5-10 cm) below the
top edge of the door, OR directly below any structural support
across the top of the door.
3. Mark, drill holes and install as follows, depending on your
door’s construction:
Metal or light weight doors using a vertical angle iron brace
between the door panel support and the door bracket:
• Drill 3/16" fastening holes. Secure the door bracket using the
two 1/4"-14x5/8" self-threading screws (Figure 2A).
• Alternately, use two 5/16" bolts, lock washers and nuts
(not provided) (Figure 2B).
Metal, insulated or light weight factory reinforced 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.

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 adjust ment
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.
Figure 4
- 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.
