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' (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 inter secting 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 9 for ceiling installation.

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 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.
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 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.
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.
Facing the door from inside the garage

Page 17
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 REVERSING
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.
• 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). To release or insert wire, push in tab
with screwdriver tip.
ALIGNING THE SAFETY REVERSING SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glowsteadily 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
TROUBLESHOOTING THE SAFETY REVERSING
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 16.

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.

INSTALLATION STEP 12
Connect Door Arm to Trolley
Follow instructions which apply to your door type as
illustrated below and on the following page.
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.
Pull the emergency release handle toward the opener at a
45° angle so that the trolley release arm is horizontal.
Proceed to Adjustment Step 1, page 23. Trolley will
re-engage automatically when opener is operated.

1. Assemble the door arm, Figure 4:
• Fasten the straight and curved door arm sections
together to the longest possible length (with a 2 or 3
hole overlap).
• With the door closed, connect the straight door arm
section to the door bracket with the 5/16"x1-1/4"
clevis pin.
• Secure with a ring fastener.
2. Adjustment procedures, Figure 5:
• On one-piece doors, before connecting the door arm
to the trolley, the travel limits must be adjusted. Limit
adjust ment screws are located on the left side panel
as shown on page 23. Follow adjustment procedures
below.
• Open door adjustment: decrease UP travel limit
- Turn the UP limit adjustment screw counter-clockwise
4 turns.
- Press the door control push button. The trolley will
travel to the fully open position.
- Manually raise the door to the open position (parallel
to the floor), and lift the door arm to the trolley. The
arm should touch the trolley just in back of the door
arm connector hole. Refer to the fully open trolley/
door arm positions in the illustration. If the arm does
not extend far enough, adjust the limit further. One
full turn equals 3" (7.5 cm) of trolley travel.
• Closed door adjustment: decrease DOWN travel
limit
- Turn the DOWN limit adjustment screw clockwise
4 complete turns.
Figure 4
- Press the door control push button. The trolley will
travel to the fully closed position.
- Manually close the door and lift the door arm to the
trolley. The arm should touch the trolley just ahead of
the door arm connector hole. Refer to the fully closed
trolley/door arm positions in the illustration. If the arm
is behind the connector hole, adjust the limit further.
One full turn equals 3" (7.5 cm) of trolley travel.
3. Connect the door arm to the trolley:
• Close the door and join the curved arm to the
connector hole in the trolley with the remaining clevis
pin. It may be necessary to lift the door slightly to make
the connection.
• Secure with a ring fastener.
• Run the opener through a complete travel cycle. If the
door has a slight “backward” slant in full open position
as shown in the illustration, decrease the UP limit until
the door is parallel to the floor.
NOTE: When setting the up limit on the following page, the
door should not have a “backward” slant when fully open
as illustrated below. A slight backward slant will cause
unnecessary bucking and/or jerking operation as the door
is being opened or closed from the fully open position.
Figure 5
22
Page 23
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 25).
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. 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.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
• 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.
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.

HOW AND WHEN TO ADJUST THE LIMITS
• If the door does not open completely but opens at
least 5 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 cm-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 21) 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.
Limit Adjustment Screws
ADJUSTMENT LABEL
• 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 18.
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.
23
Page 24
ADJUSTMENT STEP 2
Adjust the Force
Force adjustment controls are located on the back panel
of the motor unit. Force adjustment settings regulate the
amount of power required to open and close the door.
If the forces are set too light, door travel may be
interrupted by nuisance reversals in the down direction
and stops in the up direction. Weather conditions can
affect the door movement, so occasional adjustment may
be needed.
The maximum force adjustment range is about 3/4 of a
complete turn. Do not force controls beyond that
point. Turn force adjustment controls with a screwdriver.
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 FORCES
1. Test the DOWN (close) force
• Grasp the door bottom when the door is about halfway
through DOWN (close) travel. The door should reverse.
Reversal halfway through down travel does not
guarantee reversal on a 1-1/2" (3.8 cm) obstruction. See
Adjustment Step 3, page 25. If the door is hard to
hold or doesn’t reverse, DECREASE the DOWN
(close) force by turning the control counterclockwise.
Make small adjustments until the door reverses
normally. After each adjustment, run the opener through
a complete cycle.
• If the door reverses during the down (close) cycle
and the opener lights aren’t flashing, INCREASE
DOWN (close) force by turning the control clockwise.
Make small adjustments until the door completes a close
cycle. After each adjustment, run the opener through a
complete travel cycle. Do not increase the force beyond
the minimum amount required to close the door.
2. Test the UP (open) force
• Grasp the door bottom when the door is about halfway
through UP (open) travel. The door should stop. If the door is hard to hold or doesn’t stop, DECREASE UP
(open) force by turning the control counterclockwise.
Make small adjustments until the door stops easily and
opens fully. After each adjustment, run the opener
through a complete travel cycle.
• If the door doesn’t open at least 5 feet (1.5 m),
INCREASE UP (open) force by turning the control
clockwise. Make small adjustments until door opens
completely. Readjust the UP limit if necessary. After
each adjustment, run the opener through a complete
travel cycle.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
• Too much force on garage door will interfere with proper
operation of safety reversal system.
• NEVER increase force beyond minimum amount required to
close garage door.
• NEVER use force adjustments to compensate for a binding
or sticking garage door.
• 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.

1-1/2" (3.8 cm) board
(or a 2x4 laid flat)
Test the Safety Reversal System
TEST
• With the door fully open, place a 1-1/2" (3.8 cm) board
(or a 2x4 laid flat) on the floor, centered under the
garage door.
• Operate the door in the down direction. The door must
reverse on striking the obstruction.
ADJUST
• If the door stops on the obstruction, it is not traveling far
enough in the down direction. Increase the DOWN limit
by turning the DOWN limit adjustment screw
counterclockwise 1/4 turn.
NOTE: On a sectional door, make sure limit adjustments
do not force the door arm beyond a straight up and
down position. See the illustration on page 21.
• Repeat the test.
• When the door reverses on the 1-1/2" (3.8 cm) board,
remove the obstruction and run the opener through 3 or
4 complete travel cycles to test adjustment.
• If the unit continues to fail the Safety Reverse Test, call
for a trained door systems technician.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
• Safety reversal system MUST be tested every month.
• 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 the floor.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
• Each adjustment of door arm length, limits, or force
controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.
ADJUSTMENT STEP 4
Test The Protector System
• Press the remote control push button to open the door.
• Place the opener carton in the path of the door.
• Press the remote control push button to close the door.
The door will not move more than 1" (2.5 cm), and the
opener lights will flash.
The garage door opener will not close from a remote if the
indicator light in either sensor is off (alerting you to the fact
that the sensor is misaligned or obstructed).
If the opener closes the door when the safety
reversing sensor is obstructed (and the sensors are
no more than 6" (15 cm) above the floor), call for a
trained door systems technician.

PROBLEMSOLUTION
The Remote Control Battery
To prevent possible SERIOUS INJURY or DEATH:
• NEVER allow small children near batteries.
• If battery is swallowed, immediately notify doctor.
To reduce risk of fire, explosion or chemical burn:
• Replace ONLY with 3V2016 or 3V2450 coin batteries.
• Do NOT recharge, disassemble, heat above 100°C (212°F)
or incinerate.
The 3V2016 lithium batteries for the opener and LED
lights (marked “LED and Opener Battery”) should last 5
years. The 3V2450 lithium battery for the proximity lighting
(marked “Proximity Battery”) should last 1-2 years.
To replace the batteries,
remove the two screws and
open the remote control
housing. Push the battery
out of the holder for removal.
Insert replacement batteries

To Open the Door Manually
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.
The door should be fully closed if
possible. Pull down on the
emergency release handle and
lift the door manually. To
reconnect the door to the opener,
press the door control push bar.
The lockout feature prevents the
trolley from reconnecting
automatically. Pull the emergency
release handle down and back
(toward the opener). The door
can then be raised and lowered
manually as often as necessary.
To disengage the lockout feature,
pull the handle straight down.
The trolley will reconnect on the
next UP or DOWN operation,
either manually or by using the
door control or remote.
