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 transmits an invisible light beam to the receiving eye. 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.
®
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.
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.

toward each other across the door (see Figure 6).
Secure sensors with the hardware shown. Finger tighten the •
wing nut on the receiving eye to allow for final adjustment.
Securely tighten the sending eye wing nut.
Run the wires from both sensors to the opener (see Figure 7). •
Use insulated staples to secure the wire to wall and ceiling.
Strip 1/4" (6 mm) of insulation from each set of wires. Separate •
white and white/black wires sufficiently to connect to the
opener terminal screws: white to 2 and white/black to 3.
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 indicator light will glow regardless of alignment
or obstruction. If the 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 6
TROUBLESHOOTING THE SAFETY SENSORS
If the 1. 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.•
If the 2. 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.
If the 3. 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
A horizontal brace should be long enough to be secured to 2
vertical supports. A vertical brace should cover the height of the
top panel.
The illustration 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.
Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE reinforcement BEFORE installation of door bracket.
Contact your door manufacturer for reinforcement kit.
If your installation doesn't require vertical reinforce ment but does
need top and bottom fastening holes for the door bracket, fasten
as shown in Figure 2.
Center the door bracket on the previously marked vertical •
guideline used for the header bracket installation.
Position the bracket on the face of the door within the following •
limits:
The top edge of the bracket 2"-4" (5-10 cm) below the top A)
edge of the door.
The top edge of the bracket directly below any structural B)
support across the top of the door.
Mark and drill 5/16" left and right fastening holes. Secure the •
bracket as shown in Figure 1 if there is vertical reinforcement.

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.
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"
(3.8 cm) high 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 2" (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 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 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 2" (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.
20
Page 21
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
Test the DOWN (close) force1.
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 22.
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.
Test the UP (open) force2.
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"
(3.8 cm) high object (or 2x4 laid flat) on 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 19.
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.
IMPORTANT SAFETY CHECK:
Repeat Adjustment Steps 1, 2 and 3 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.•
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"
(3.8 cm) high object (or 2x4 laid flat) on the floor.
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 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.
