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 9.
3.Open your door to the highest point of travel as
shown. Draw an intersecting horizontal line on the
header wall 3" above the high point. This height
will provide travel clearance for the top edge of the
door.
Proceed to Step 2, page 10. One-piece
door with
horizontal
track
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

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 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.

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.

MOUNTING 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 (Figure 4).
•Finger tighten the wing nuts.
Recommended Wire Routing
1.Using insulated staples, run the wires from both
sensors to the rail at the door header (Figure 5).
2.Cross and twist the two wires where they meet
the rail (see inset A). Run the wires inside the
channels at the top of the rail, along each side,
to the motor unit. Do not use the lower (trolley)
channels. Use a screwdriver tip to tuck the wires
snugly into the channels.
NOTE: If your access door is near the garage
door, you may choose to install the door control at
this time and run the door control wire along the
rail with the sensor wires. Use one rail channel for
the door control wire and the other channel for
both sensor wires. If you choose this option, follow
instructions 1-3 on page 17 now.
3.Pull wires taut across the top of the chassis and
insert into the opening above the terminal block
(see inset B). You will complete the wiring in
Installation Step 7.

INSTALLATION STEP 6
Hang the Opener
Two 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"-18x1-7/8" lag screws.
5.Fasten the opener to the hanging brackets with
5/16"-18x7/8" 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 2x4. Operate the door manually. If the
door hits the rail, raise the header bracket.
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 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 (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" 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 6-32x1" 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.
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 14.
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" 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 19.

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
endpanel or light socket.
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" 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 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.
• 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.
RIGHT WRONG
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.

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 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 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 12.

INSTALLATION STEP 12
Fasten the Door Bracket
Follow instructions which apply to your door type
as illustrated below or on the following page.
Ahorizontal 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" 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.
