Depending on your requirements, there are several
installation steps which may call for materials or
hardware not included in the carton.
• Installation Step 1 - Look at the wall or ceiling
above the garage door. The header bracket must
be securely fastened to structural supports.
• Installation Step 5 - Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• Installation Step 10- Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 10 -Alternate floor mounting of
the safety reversing sensor will require hardware
not provided.
Do you have an access door in addition to the
garage door? If not, Model 53702 Emergency Key
Release is required. See Accessories page.
Look at the garage door where it meets the floor.
Any gap between the floor and the bottom of the
door must not exceed 1/4" (6 mm). Otherwise, the
safety reversal system may not work properly. See
Adjustment Step 3. Floor or door should be
repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horiFontal and vertical
reinforcement is required (Installation Step 11).
• The opener should be installed above the center of
the door. If there is a torsion spring or center
bearing plate in the way of the header bracket, it
may be installed within 4 feet (1.22 m) to the left or
right of the door center. See Installation Steps 1
and 11.
• If your door is more than 7 feet (2.13 m) high, see
rail extension kits listed on Accessories page.

INSTALLATION STEP 6
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).
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.
2. Remove cover by gently prying at slot in side of
the cover with a small flat head screwdriver
(Figure 1). 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.
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

INSTALLATION STEP 9
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 SERIOUSINJURYor DEATHfrom
electrocution or fire:
• Besure power is not connected to the opener, and
disconnect power to circuit BEFOREremoving cover to
establish permanentwiring connection.
• Garagedoor installation andwiring MUSTbe in
compliance with all localelectrical and building codes.
• NEVERusean extensioncord, 2-wire adapter,or
changeplug in anyway to makeit fit outlet. Besure
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 connectedto the garage door
opener BEFOREinstalling the safety reversingsensor
• To prevent SERIOUSINJURYor DEATHfrom a closing
garagedoor:
- Correctly connect and alignthe safety reversing
sensor This requiredsafety device MUSTNOTbe
disabled.
- Install the safety reversingsensor so beam is NO
HIGHERthan 6" (15 cm) above garagefloor
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.

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):
• 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 (Figure 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 SENSORS
• Slide a 1/4"-20xl/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 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
Carriage Bolt _)
1/4"-20xl/2"
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. See page 20.

INSTALLATION STEP 1 1
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.
The illustration shows one piece of angle iron as the
horizontal brace. For the vertical brace, two pieces of
angle iron are used to create a U-shaped support
(Figure 1). The best solution is to check with your
garage door manufacturer for an opener installation
door reinforcement kit.
NOTE: Many vertical brace installations provide for
direct attachment of the clevis pin and door arm. In
this case you will not need the door bracket; proceed
to Installation Step 12.
SECTIONAL DOORS
• 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 (Figure 2).
• Position the bracket on the face of the door within
the following limits:
A) The top edge of the bracket 2"-4" (5-10 cm)
below the top edge of the door.
B) The top edge of the bracket directly below any
structural support across the top of the door.
To prevent damageto garage door, reinforceinside of
door both vertically and horizontally.
