Before you begin:
• Disable locks.
• Remove any ropes connected to garage door.
• Complete the following test to make sure your garage
door is balanced and is not sticking or binding:
1. Lift the door about halfway as shown. Release the
door. If balanced, it should stay in place, supported
entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.
Tools needed
During assembly, installation and adjustment of the
opener, instructions will call for hand tools as illustrated
below.
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and operating the
opener.
• ONLY operate garage door opener at 120V, 60 Hz to avoid
malfunction and damage.
To prevent possible SERIOUS INJURY or DEATH:
• ALWAYS call a trained door systems technician if garage
door binds, sticks, or is out of balance. An unbalanced

the installation of your opener.
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 4 – Depending upon garage
construction, extension brackets or wood blocks may be
needed to install sensors.
• Installation Step 4 – Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.
• Installation Step 6 – Do you have a finished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
• Do you have an access door in addition to the garage
door? If not, Model 7702CB 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.

INSTALLATION STEP 1
Determine the Header Bracket
Location
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 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 intersecting horizontal line on the header wall
above the high point:
• 3" (7.5 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.
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.

Facing the door from inside the garage
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 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.
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" (15 cm) 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"
(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 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 5).
• 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 5A).
2. Run the wires through wire clips at the top of the rails.
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.
3. Separate the white and white/black wires. Strip 7/16”
(11 mm) of insulation from the end of the sensor wires.
Twist like colored wires together. Connect the bell wire
from safety reversing sensors to the quick-connect
terminals: white wires to the white terminal and white/
black wires to grey terminal (Figure 5B).

ONE-PIECE DOOR WITHOUT TRACK
A 2x4 on its side is convenient for setting an ideal
door-to-rail distance.
• Remove foam packaging.
• Raise the opener onto a stepladder. You will need
help at this point if the ladder is not tall enough.
• Open the door all the way and place a 2x4 on its
side on the top section of the door beneath the
rail.
• The top of the door should be level with the top of
the motor unit. Do not position the opener more
than 4" (10 cm) above this point.
INSTALLATION STEP 5
Position the Opener
Follow instructions which apply to your door type as
illustrated.
SECTIONAL DOOR OR ONE-PIECE DOOR WITH
TRACK
A 2x4 laid flat is convenient for setting an ideal door-to-rail
distance.
• Remove foam packaging.
• Raise the opener onto a stepladder. You will need help
at this point if the ladder is not tall enough.
• Open the door all the way and place a 2x4 laid flat on
the top section beneath the rail.
• If the top section or panel hits the trolley when you raise
the door, pull down on the trolley release arm
to disconnect inner and outer sections. Slide the outer
trolley toward the motor unit. The trolley can remain
disconnected until Installation Step 14 is completed.
To prevent damage to garage door, rest garage door opener
rail on 2x4 placed on top section of door.

INSTALLATION STEP 6
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 (see
accessories).
Existing brackets from a previous installation may be
fastened to the sides of the motor unit as in Figures 1, 2
and 3. Then continue with step 6 below.
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.

INSTALLATION STEP 7
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. 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).
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 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. (Standard installation only) Run bell wire up wall and
across ceiling to opener. 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 17.
4. Separate the white and red/white wires. Strip 7/16"
(11 mm) of insulation from the end of the bell wires.
Twist like colored wires together. Connect the bell wire
from door control and safety reversing sensors to the
quick-connect terminals: red/white wire to the red
terminal, white wires to the white terminal and white/
black wires to grey terminal.
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 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
12 on Page 22.
