(on wall or ceiling), use lag screws (not provided)
to securely fasten the 2x4 to structural supports as
shown here and on page 0.
3. Open your door to the highest point of travel as
shown. Draw an intersecting horizontal line on the
header wall 2" above the high point. This height will
provide travel clearance for the top edge of the
door.
Proceed to Step , page 10. One-piece

Electrical Requirements
To avoid ins alla ion difficul ies, do no run he
opener a his ime.
To reduce the risk of electric shock, your garage door
opener has a grounding type plug ith a third
grounding pin. This plug ill 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 permanen wiring is required by your local
code, refer o he following procedure.
To make a permanent connection through the 7/8"
hole in the top of the motor unit:
• Remove the motor unit cover scre s and set the
cover aside.
• Remove the attached 3-prong cord.
• Connect the black (line) ire to the scre on the
brass terminal; the hite (neutral) ire to the scre
on the silver terminal; and the ground ire to the
green ground scre . The opener mus be
grounded.
• Reinstall the cover.
To avoid ins alla ion difficul ies, do no run he
opener a his ime.
RIGHT WRONG
To prevent possible SERIOUS IN URY 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.

IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
When properly connected and aligned, the sensor
ill detect an obstacle in the path of its electronic
beam. The sending eye ( ith an orange indicator
light) transmits an invisible light beam to the
receiving eye ( ith a green indicator light). If an
obstruction breaks the light beam hile the door is
closing, the door ill stop and reverse to full open
position, and the opener lights ill 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 ithout additional
hard are.
If it is necessary to mount the units on the all, the
brackets must be securely fastened to a solid
surface such as the all framing. Extension brackets
(see accessories) are available if needed. If installing
in masonry construction, add a piece of ood 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 hard are) may interrupt the
beam hile the door is closing.
• Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
• To prevent SERIOUS IN URY 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 o he opener is disconnec ed.
Install and align the brackets so the sensors ill face
each other across the garage door, ith the beam no
higher than 6" above the floor. They may be installed
in one of three ays, as follo s.
Garage door track installation (preferred):
• Slip the curved arms over the rounded edge of
each door track, ith the curved arms facing the
door. Snap into place against the side of the track.
It should lie flush, ith the lip hugging the back
edge of the track, as sho n in Figure 1.
If your door track ill not support the bracket
securely, all installation is recommended.
Wall installation:
• Place the bracket against the all ith 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 ood blocks can be used.
• Use bracket mounting holes as a template to locate
and drill (2) 3/16" diameter pilot holes on the all at
each side of the door, no higher than 6" above the
floor.
• Attach brackets to all ith lag scre s
(not provided).
• If using extension brackets or ood blocks, adjust
right and left assemblies to the same distance out
from the mounting surface. Make sure all door
hard are obstructions are cleared.
Floor installation:
• Use ood blocks or extension brackets (see
Accessories) to elevate sensor brackets so the
lenses ill be no higher than 6" above the floor.
• Carefully measure and place right and left
assemblies at the same distance out from the all.
Be sure all door hard are obstructions are cleared.
• Fasten to the floor ith concrete anchors as sho n.

TROUBLESHOOTING THE SAFETY SENSORS
1. If the sending eye indicator light does not glo
steadily after installation, check for:
• Electric po er to the opener.
• A short in the hite or hite/black ires. These
can occur at staples, or at opener connections.
• Incorrect iring bet een sensors and opener.
• A broken ire.
2. If the sending eye indicator light glo s steadily but
the receiving eye indicator light doesn't:
• Check alignment.
• Check for an open ire 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 17.

MOUNTING AND WIRING THE SAFETY SENSORS
• Slide a 1/4"-20x1/2" carriage bolt head into the slot
on each sensor. Use ing nuts to fasten sensors to
brackets, ith lenses pointing to ard each other
across the door. Be sure the lens is not obstructed
by a bracket extension (Figure 4).
• Finger tighten the ing nuts.
• Run the ires from both sensors to the opener. Use
insulated staples to secure ire to all and ceiling.
• Strip 7/16" of insulation from each set of ires.
Separate hite and hite/black ires sufficiently to
connect to the opener quick-connect terminals: hite
to hite and hite/black to black (Figure 5).
ALIGNING THE SAFETY SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes ill glow steadily if
iring connections and alignment are correct.
The sending eye orange indicator light ill glo
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 ing nut and readjust,
aiming directly at the receiving eye. Lock in place.
• Loosen the receiving eye ing nut and adjust sensor
until it receives the sender’s beam. When the green
indicator light glo s steadily, tighten the ing nut.

INSTALLATION STEP 11
Fasten the Door Bracket
Follo instructions hich apply to your door type
as illustrated belo or on the follo ing page.
A horizon al reinforcemen brace should be long
enough o be secured o wo or hree ver ical
suppor s. A ver ical reinforcemen brace should
cover he heigh of he op panel.
Figure 1 sho s 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 ith 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" belo
the top edge of the door, OR directly belo any
structural support across the top of the door.
3. Mark, drill holes and install as follo s, depending
on your door’s construction:
Metal or light weight doors sing a vertical angle
iron brace between the door panel s pport and
the door bracket:
• Drill 3/16" fastening holes. Secure the door bracket
using the t o 1/4"-14x5/8" self-threading scre s.
(Figure 2A)
• Alternately, use t o 5/16" bolts, lock ashers and
nuts (not provided). (Figure 2B)
Metal, ins lated or light weight factory reinforced
doors:
• Drill 3/16" fastening holes. Secure the door bracket
using the self-threading scre s (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 ith 5/16"x2" carriage bolts, lock ashers
and nuts (not provided). (Figure 4)
NOTE: The 1/4"-14x5/8" self-threading screws are
not intended for use on wood doors.
