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

Install The Safety Reversing Sensor
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 green 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 higher than 6" 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.
WARNING
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" 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.

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" 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
(not provided) 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" 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:
Use wood blocks or extension brackets (
) to elevate sensor brackets so the
lenses will be no higher than 6" above the floor.

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 green 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 indicator light does not
after installation, check for:
sending eye glow
steadily
Electric power to the opener.
A short in the wires. These can occur at staples,
or at screw terminal 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 flash 10 times. See page 19.

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 vertical supports. A
vertical reinforcement 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, two pieces of
angle iron are used to create a "U''-shaped support
(Figure 1). The best solution is to check with your
garage door manufacturer for an opener installation
door reinforcement kit.
NOTE: Many vertical brace installations provide for
direct attachment of the clevis pin and door arm. In
this case you will not need the door bracket; proceed
to Installation Step 12.
SECTIONAL DOORS
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 (Figure 2).
Position the bracket on the face of the door within
the following limits:
A) The top edge of the bracket 2"-4" below the top
edge of the door.
B) The top edge of the bracket directly below any
structural support across the top of the door.
CAUTION
To prevent damage to garage door, reinforce inside of
door with angle iron both vertically and horizontally.
Mark and drill15/16" left and right fastening holes.
Secure the bracket as shown in Figure 1 if there is
vertical reinforcement.
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.
Horizontal and vertical reinforcement
is needed for lightweight garage doors
(fiberglass, aluminum, steel, doors with
glass panel, etc). (Not Provided)

Change the location of the remote control in your car.
Check to be sure the antenna on the side or back panel of
motor unit extends fully downward.
Some installations may have shorter range due to a metal
door, foil backed insulation, or metal garage siding.
5. The garage door opens and closes by itself:
Be sure that all remote control push buttons are off.
Remove the bell wire from the door control terminals and
operate from the remote only. If this solves the problem, the
door control is faulty (replace), or there is an intermittent short
on the wire between the door control and the motor unit.
Clear memory and re-program all remote controls.
6. The door doesn't open completely:
Is something obstructing the door? Is it out of balance, or
are the springs broken? Remove the obstruction or repair
the door.
If the door is in good working order but now doesn't open
all the way, increase the up force. See 1Adjustment Step .
If the door opens at least 5 feet, the travel limits may need
to be increased. One turn equals 2 inches of travel. See
Adjustment Step 1.
Repeat the safety reverse test after the adjustment is
complete.
7. The door stops but doesn't close completely:
Review the Adjustment Step1.
Repeat the safety reverse test after any adjustment of door
arm length, close force or down limit.
8. The door opens but won't close:
If the opener light blinks, check the safety reversing sensor.
See Installation Step 10.
If the opener light doesn't blink and it is a new installation,
check the down force. See Adjustment Step 1, page 24.
For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
9. The door reverses for no apparent reason and opener
light doesn't blink:
Is something obstructing the door? Pull the emergency
release handle. Operate the door manually. If it is unbalanced
or binding, call a trained door systems technician.
Clear any ice or snow from the garage floor area where
the door closes.
Review Adjustment Step 1 on page 24.
If door reverses in the fully closed position, see Adjustment
Step 1.
Repeat safety reverse test after adjustments to force and travel
limits. The need for occasional adjustment of the force and
limit settings is normal. Weather conditions in particular can
affect door travel.
10. The door reverses for no apparent reason and opener
light blinks for 5 seconds after reversing:
Check the safety reversing sensor. Remove any obstruction
or align the receiving eye. See Installation Step 10.
11, The opener light doesn't turn on:
Replace the light bulb (75 watts maximum). Use a standard
neck garage door opener bulb if regular bulb burns out.
12. The opener strains or maximum force is needed to
operate door:
The door may be out of balance or the springs may be
broken. Close the door and use the emergency release
handle to disconnect the trolley. Open and close the door
manually. A properly balanced door will stay in any point of
travel while being supported entirely by its springs. If it
does not, disconnect the opener and call a trained door
systems technician. Do not increase the force to operate
the opener.
13. The opener motor hums briefly, then won't work:
The garage door springs may be broken. See above.
If the problem occurs on the first operation of the opener,
door may be locked. Disable the door lock. If the chain was
removed and reinstalled, the motor may be out of phase.
Remove the chain; cycle the motor to the down position.
Observe the drive sprocket. When it turns in a clockwise
direction and stops in the down position, reinstall the chain.
Repeat the safety reverse test after the adjustment is
complete.
14. The opener won't operate due to power failure:
Use the emergency release handle to disconnect the
trolley. The door can be opened and closed manually.
When power is restored, press the Door Control push
button and trolley will automatically reconnect (unless
trolley is in lockout position.) See page 24.
The Emergency Key Release accessory (for use on
garages with no service door) disconnects the trolley from
outside the garage in case of power failure.
15. The chain droops or sags:
It is normal for the chain to droop slightly in the closed door
position. Use the emergency release to disconnect the
trolley. If the chain returns to normal height when the trolley
is disengaged and the door reverses on a one-inch board,
no adjustments are needed (see page 10).
