INSTALLATION STEP 1
Determine the Header Bracket
Location
SECTIONAL DOOR ONLY
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 9) 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 9.
3. Open your door to the highest point of travel as
shown. Draw an intersecting horizontal line on the
header wall 2" (5 cm) above the high point. This
height will provide travel clearance for the top edge
of the door.
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.

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.
8. Grease the top and underside of the rail surface
where the trolley slides with rail grease.
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

INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of the door at a
minimum height of 5 feet (1.5 m) 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" (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 (Figure 3).
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:
• 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 top 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.
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 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 Safety Reversing Sensor information
beginning on page 15.
To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is not connected BEFORE installing door
control.
• Connect ONLY to 24 VOLT low voltage wires.
To prevent possible SERIOUS INJURY or DEATH from a
closing garage door:
• Install door control within sight of garage door, out of
reach of children at a minimum height of 5 feet (1.5 m),
and away from all moving parts of door.
• NEVER permit children to operate or play with door
control push buttons or remote control transmitters.
• Activate door ONLY when it can be seen clearly, is
properly adjusted, and there are no obstructions to door
travel.
• ALWAYS keep garage door in sight until completely
closed. NEVER permit anyone to cross path of closing
garage door.

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.
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.

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.
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:
• 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
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.
• 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 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.

Figure 4MOUNTING 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.
•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 5).
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.
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 15 .

INSTALLATION STEP 11
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 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 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"
(5-10 cm) 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.

SECTIONAL DOORS ONLY
• Make sure garage door is fully closed. Pull the
emergency release handle to disconnect the outer
trolley from the inner trolley. Slide the outer trolley
back (away from the door) about 2" (5 cm) as
shown in Figures 1, 2 and 3.
• Figure 1:
– Fasten straight door arm section to outer trolley
with the 5/16"x1" clevis pin. Secure the
connection with a ring fastener.
– Fasten curved section to the door bracket in the
same way, using the 5/16"x1-1/4" clevis pin.
• Figure 2:
– Bring arm sections together. Find two pairs of
holes that line up and join sections. Select holes
as far apart as possible to increase door arm
rigidity.
• Figure 3, Hole alignment alternative:
– If holes in curved arm are above holes in straight
arm, disconnect straight arm. Cut about 6"
(15 cm) from the solid end. Reconnect to trolley
with cut end down as shown.
– Bring arm sections together.
– Find two pairs of holes that line up and join with
bolts, lock washers and nuts.
• Proceed to Adjustment Step 1, page 20. Trolley will
re-engage automatically when opener is operated.

ADJUSTMENT STEP 1
Adjust the UP and DOWN Travel
Limits
Limit adjustment settings regulate the points at which
the door will stop when moving up or down.
To operate the opener, press the Door Control push
bar. Run the opener through a complete travel cycle.
• Does the door open and close completely?
• Does the door stay closed and not reverse
unintentionally when fully closed?
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test
fails (Adjustment Step 3, page 22).
Adjustment procedures are outlined below. Read the
procedures carefully before proceeding to
Adjustment Step 2. Use a screwdriver to make limit
adjustments. Run the opener through a complete
travel cycle after each adjustment.
NOTE: Repeated operation of the opener during
adjustment procedures may cause the motor to
overheat and shut off. Simply wait 15 minutes and
try again.
NOTE: If anything interferes with the door’s upward
travel, it will stop. If anything interferes with the
door’s downward travel (including binding or
unbalanced doors), it will reverse.
HOW AND WHEN TO ADJUST THE LIMITS
• If the door does not open completely but opens
at least five feet (1.5 m):
Increase up travel. Turn the UP limit adjustment
screw clockwise. One turn equals 3" (7.5 cm) of
travel.
NOTE: To prevent the trolley from hitting the cover
protection bolt, keep a minimum distance of 2-4"
(5-10 cm) between the trolley and the bolt.
• If door does not open at least 5 feet (1.5 m):
Adjust the UP (open) force as explained in
Adjustment Step 2.
• If the door does not close completely:
Increase down travel. Turn the down limit
adjustment screw counterclockwise. One turn
equals 3" (7.5 cm) of travel.
If door still won't close completely and the trolley
bumps into the pulley bracket (page 4), try
lengthening the door arm (page 19) and
decreasing the down limit.
• If the opener reverses in fully closed position:
Decrease down travel. Turn the down limit
adjustment screw clockwise. One turn equals 3"
(7.5 cm) of travel.
• If the door reverses when closing and there is
no visible interference to travel cycle:
If the opener lights are flashing, the Safety
Reversing Sensors are either not installed,
misaligned, or obstructed. See Troubleshooting,
page 17.
Test the door for binding: Pull the emergency
release handle. Manually open and close the door.
If the door is binding or unbalanced, call for a
trained door systems technician. If the door is
balanced and not binding, adjust the DOWN
(close) force. See Adjustment Step 2.

• Incorrect adjustment of garage door travel limits will
interfere with proper operation of safety reversal
system.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 1-1/2" high (3.8 cm) object (or 2x4 laid
flat) on floor.
