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 garage door may NOT reverse when
required.
• NEVER try to loosen, move or adjust garage door,
door springs, cables, pulleys, brackets or their
hardware, ALL of which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected
to garage door BEFORE installing and operating
garage door opener to avoid entanglement.
Preparing Your Garage Door
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.

Planning
Identify the type and height of your garage door. Survey
your garage area to see if any of the conditions below
apply to your installation. Additional materials may be
required. You may find it helpful to refer back to this page
and the accompanying illustrations as you proceed with
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 5 – Do you have a finished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
• Installation Step 11 – Depending upon garage
construction, extension brackets or wood blocks may
be needed to install sensors.
• Installation Step 11 – 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 7702C 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, horizontal and vertical reinforcement
is required (Installation Step 12).
• 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 (1.2 m) to the left or right of the door
center. See Installation Steps 1 and 12.
• If your door is more than 7 feet (2.1 m) high, see rail
extension kits listed on Accessories page.
See page 24 for details. See page 16.

Planning (Continued)
ONE-PIECE DOOR INSTALLATIONS
• Generally, a one-piece door does not require
reinforcement. If your door is lightweight, refer to the
information relating to sectional doors in Installation
Step 12.
• Depending on your door’s construction, you may need
additional mounting hardware for the door bracket
(Step 12).
Without a properly working safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• The gap between the bottom of the garage door and
the floor MUST NOT exceed 1/4" (6 mm). Otherwise,
the safety reversal system may NOT work properly.
• The floor or the garage door MUST be repaired to
eliminate the gap.

ASSEMBLY STEP 1
Assemble the Rail & Install the Trolley
To avoid installation difficulties, do not run the garage
door opener until instructed to do so.
The front rail has a cut out “window” at the door end
(see illustration). The hole above this window is larger on
the top of the rail than on the bottom. A smaller hole
3-1/2" (8.9 cm) away is close to the rail edge. Rotate the
back rail so it has a similar hole close to the opposite
edge, about 4-3/4" (12 cm) from the far end.
1. Remove the straight door arm and hanging bracket
packaged inside the front rail and set aside for
Installation Step 5 and 12. NOTE: To prevent INJURY
while unpacking the rail carefully remove the straight
door arm stored within the rail section.
2. Align the rail sections on a flat surface as shown and
slide the tapered ends into the larger ones. Tabs along
the side will lock into place.
3. Place the motor unit on packing material to protect
the cover, and rest the back end of the rail on top.
For convenience, put a support under the front end of
the rail.

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:
• 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 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.

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
(Figures 2 and 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"-9x1-5/8" 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.
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.

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).
NOTE: The functional temperature range of the door
control is between -4° F (-20° C) and 122° F (50° C).
Scroll speed of display is slower at lower temperatures
although the door control remains fully functional.
CAUTION: Continuous exposure of the door control to
temperatures below -22° F (-30° C) may damage the LCD
screen.
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 W (2) and white/red
wire to the R (1).
2. Remove cover by gently prying at slot in top of the
cover with a small flat head screwdriver. Fasten with
6ABx1" 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.
5. Position the antenna wire as shown.
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 power and operate 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.
To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Disconnect ALL electric and battery power BEFORE
performing ANY service or maintenance.
• Connect ONLY to 24 VOLT low voltage wires.
To prevent possible SERIOUS INJURY or DEATH from
a closing garage door:

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 9
Attach the Emergency Release Rope
and Handle
1. Insert one end of the emergency release rope through
the handle. Make sure that “NOTICE” is right side up.
Tie a knot at least 1 inch (2.5 cm) from the end of the
emergency release rope.
2. Insert the other end of the emergency release rope
through the hole in the trolley release arm. Mount the
emergency release within reach, but at least 6 feet
(1.83 m) above the floor, avoiding contact with vehicles
to prevent accidental release and secure with a knot.
NOTE: If it is necessary to cut the emergency release
rope, seal the cut end with a match or lighter to prevent
unraveling. Ensure the emergency release rope and handle
are above the top of all vehicles to avoid entanglement.
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:
1. Remove the motor unit cover screws and set the cover
aside.
2. Remove the attached 3-prong cord.
3. 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.
4. 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:
• Disconnect ALL electric and battery power BEFORE
performing ANY service or maintenance.
• 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 11
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.
Facing the door from inside the garage.
