INSTALLATION STEP 5
Hang the Opener
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.
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.
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.
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.

INSTALLATION STEP 6
Install the Door Control
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.
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.
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 or amber
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 WHT and white/red
wire to the RED (Figure 3).
2. Remove cover by gently prying at slot in the top of the
cover with a small flat head screwdriver (Figure 4).
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" (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.
• Install top screw with care to avoid cracking plastic
housing. Do not overtighten.
• Insert bottom 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 (Figure 5).
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 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.

INSTALLATION STEP 8
Attach the Emergency Release Rope
and Handle
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.
• Thread one end of the rope through the hole in the top
of the red handle so “NOTICE” reads right side up as
shown. Secure with an overhand knot at least 1"
(2.5 cm) from the end of the rope to prevent slipping.
• Thread the other end of the rope through the hole in the

Electrical Requirements
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.
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.
PERMANENT WIRING
CONNECTION
RIGHT
WRONG
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.

INSTALLATION STEP 10
Install The Protector System®
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.
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.
Safety Reversing Sensor
6" (15 cm) max. above 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.

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 quickconnect holes: white to white and white/black to grey
(Figure 6).

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.
ALIGNING THE SAFETY REVERSING 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.

INSTALLATION STEP 11
Fasten the Door Bracket
Fiberglass, aluminum or lightweight steel garage doors WILL
REQUIRE reinforcement BEFORE installation of door bracket.
Contact your door manufacturer for reinforcement kit.
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.

- 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 2" (5 cm) of trolley travel.
• Closed door adjustment: decrease DOWN travel

• 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.

ADJUSTMENT STEP 1
Adjust the UP and DOWN Travel Limits
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.
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.
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 five feet (1.5 m):
Increase up travel. Turn the UP limit adjustment screw
clockwise. One turn equals 2" (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.
Left Side Panel
• If door does not open at least 5 feet (1.5 m):
Adjust the UP (open) force as explained in Adjustment
Step 2.
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.
• If the door does not close completely:
Increase down travel. Turn the down limit adjustment
screw counterclockwise. One turn equals 2" (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 2" (5 cm) of travel.
23
ADJUSTMENT STEP 2
Adjust the Force
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.
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.

Test the Safety Reversal System
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.
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.
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.

KILLED by a closing garage door.
• 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 an inch (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.

6. My motor unit hums briefly:
• First verify that the trolley is against the stop bolt.
• Release the door from the opener by pulling the
Emergency Release Rope.
• Manually bring the door to a closed position.
• Loosen the chain by adjusting the outer nut 4 to 5
turns. This relieves the tension.
• Run the motor unit from the remote control or door
control. The trolley should travel towards the door and
stop. If the trolley re-engages with the door, pull the
Emergency Release Rope to disengage.
• Decrease the UP travel by turning the UP Travel
adjustment screw 2 full turns away from the arrow.
• Re-tighten the outer nut so the chain is a 1/2" (13 mm)
above the base of the rail. (When the door is
reconnected and closed, the chain will sag. This is
normal.)
• If the trolley does not move away from the bolt, repeat
the steps above.
3. My door reverses for no apparent reason: Repeat
safety reverse test after adjustments to force or travel
limits. The need for occasional adjustment for the force
and limit settings is normal. Weather conditions in
particular can affect door travel.
• Manually check door for balance or any binding
problems.
• Refer to Adjustment Step 2, Adjust the Force.
4. My door reverses for no apparent reason after fully
closing and touching the floor: Repeat safety reverse
test after adjustments to force or travel limits. The need
for occasional adjustment for the force and limit settings
is normal. Weather conditions in particular can affect
door travel.
• Refer to Adjustment Step 1, Adjust the UP and DOWN
Travel Limits. Decrease down travel by turning down
limit adjustment screw clockwise.
5. My lights will not turn off when door is open:
• The garage door opener is equipped with a security
light feature. This feature activates the light on when
the safety sensor beam has been obstructed. Refer to
Operation section; Using the Wall Mounted Door
Control, Light Feature.
