Installation requirements vary with garage construction.
Hanging brackets should be angled to provide rigid
support. Hanging material is not provided. Angle iron
and lag screws are recommended. DO NOT USE NAILS.
Following are typical operator hanging methods. Certain
installations will require improvised methods.
1Raise the operator head and set it on top of a
stepladder (use extra spacers on top of ladder if it
isn’t tall enough).
2 Carefully open the door to the full up position. Lay a
2x4 across the top section of the door as a spacer.
Adjust the operator height until the rail touches the
spacer. The rail should be close to level.
3 Center the operator head and rail with the centerline
mark on the top of the door.
4 For finished ceilings only: An angle iron cross piece
between the two closest joists above the operator will
be required. Mark mounting hole locations, drill pilot
holes and attach the piece with two lag screws (not
supplied).
5Measure the distance from each of the operator’s
hanging tabs to the ceiling joists or angle iron cross
piece.
6 Cut two angle iron pieces to the required lengths for
hanging brackets. Bend brackets if required.
• For unfinished ceilings: Hold each bracket in place
and use a pencil to mark the locations where they will
be attached to the joists, drill pilot holes and attach
the pieces with two lag screws (not supplied).
• For finished ceilings with an angle iron cross piece:
Attach the two hanging brackets to the cross piece
with two bolts and two keps nuts (not supplied).
7Attach operator to hanging brackets using two
5/16-18 x 1” hex bolts and two 5/16-18 keps nuts
(supplied). Insert bolts from the inside of hanger
brackets with the nuts on the outside of the operator.
Tighten nuts with a ½” socket.
8 Tighten all hanging hardware.
9 Open and close the door manually. The door should
clear the rail by at least 1”.
10Attach the trolley’s release lever to the red release
handle with the cord supplied so the handle is at
least 6 feet from the floor. Cut off any excess cord.

1 It is paramount that the Smart Control Wall Station
receives strong signal from your home’s Wi-Fi router.
Before you affix the Wall Station to the wall, survey
your location to check the Wi-Fi signal. To do this,
take a smart phone, connect it to your Wi-Fi network
and then place your phone on the wall where you
want to attach the Wall Station.
If you have 2 or 3 bars on your phone for the Wi-Fi
network, the signal is strong and you can proceed.
If not, use one of these options to extend your Wi-Fi
network’s range.
• Move your Wi-Fi router closer to the garage.
• Purchase a Wi-Fi range extender.
2 Strip back ½” of insulation and connect a wire to
each of the two terminals on the back of the wall
station. NOTE: Polarity is CRITICAL (make note to
connect Common to Common and Wall Station to
Wall Station).
3 Use the screws provided to mount the wall station
near an access door at a minimum height of five feet.
SEE IMPORTANT WARNING ABOVE!
4For non-prewired installations, route the wire to
the back of the operator. Use insulated staples (not
supplied) to secure the wire. Staples must straddle
both wires to avoid electrical shorts.
5 Cut the wall station wire about 6” longer than needed to
reach the operator terminals. Strip back ½” of insulation.
6Connect wires to the operator’s WALL STATION

if necessary to create proper clearance.
1 Assemble the two safety beam brackets from the four
L-shaped brackets using two ¼-20 x ¾” bolts and
¼‑20 keps nuts (one nut & bolt for each bracket).
2 Position the assembled brackets on each side of the
door so the center line of the safety beam lenses
will be 5-1/2” above the floor. Use the index marks
on the brackets to make the bracket assemblies
equal lengths. Mark the locations for the bracket
mounting screws.
NOTE: The safety beam receiver (the unit with two
indicators) should be located on the “shady” side of
the door to prevent sunlight from shining directly into
the receiver’s lens.
3 Drill two 3/16” pilot holes for lag screws at marks.
Mount the brackets with two ¼” x 1-¼” lag screws
and tighten with a 7/16” socket.
4 Insert the sender and receiver into the bracket holes
so the lenses of the units will face each other. Twist the
units until the spring clips lock into a detent mark on
the brackets. To protect the units from being bumped
after installation, it is recommended to mount the
sender and receiver inside the brackets as shown.
• IMPORTANT: Be careful to route the safety beam
wiring away from any moving parts of the door or
operator.
5 For non-prewired installations, route the wires from
the sender and receiver, up the wall above the door
hardware, then over to the center of the door, then
along the top of the rail (or ceiling), and back to the
operator head. Cut the wires about 6” longer than
needed to reach the operator terminals. Strip back ½”
of insulation from the ends of the wires.
6 For non-prewired installations, secure all the wires
to the wall and ceiling with insulated staples (not
supplied). Staples must straddle both wires to
prevent shorts. Secure the wire to the top of the rail
with wire clips (supplied).
7 At the operator, twist one wire from each pair together,
then twist the other wire from each pair together.
8Attach either twisted connection to the operator’s
BEAM terminal. Connect the other twisted connection
to the operator’s COMMON terminal.

12 Aligning the Infrared Safety Beam
14 Adjusting the Open and Close Limits
The safety beam has two components, a sender and a receiver. The sender produces a narrow infrared beam
that travels across the bottom of the door opening to the infrared receiver. If an object blocks the infrared beam
while the door is closing, the door will stop, then reverse and fully open (the operator’s light will flash three times).
As a safety feature, the operator will ignore signals from all remote controls if the door is open and the infrared
safety beam is blocked or out of alignment. In this case, the door can be forced closed by pressing and holding
the wall station’s up/down arrow pushbutton (be sure the door area is in clear view).
The limit settings control how far the door will open and close. Set the limits so the door opens just short of any
door stops, and closes at the floor level. Out of the box, the operator is preset on its close limit and the
open limit is preset for a typical 7-foot high door.
Use the wall station or a transmitter to test operate the
door. If required, use the following steps to adjust the
limits.

 WARNING 
With the door closed, disengage the trolley from
the chain or belt during these alignment tests
by pulling the red release handle.
Safety Beam Test
1 Check that the operator has power. The green lights
on the sender and receiver should be lit.
2 If the receiver’s green light is on, but the red light is
off, the receiver has power but is not detecting the
infrared beam from the sender. The red light might
flash when the beam is partially detected. This can
be caused by mis-alignment or something blocking
the beam. Adjust the safety beam sender and receiver
while watching the receiver’s red light (stay out of the
beam while aligning it). When the red light stays on,
rotate the sender towards the ceiling and stop when
the red light on the receiver begins to flicker. Rotate
the sender back towards a horizontal position with the
floor and stop as soon as the red light on the receiver
lights solid. The beam is now properly aligned.

NOTE: If the receiver’s red light remains off, check
for: 1) Dirt on the receiver’s lens, 2) Sunlight shining
into the receiver’s lens, 3) A short in the safety beam
wiring (from staples or at the operator terminals).
3 With the door closed and the operator disengaged
from the door, press the wall station’s UP/DOWN
ARROW button to move the traveler (the part on the
belt or chain that the trolley engages with) to the up
position (away from the door). NOTE: Do not cycle the
operator to full travel without the door connected.
4 Push the wall station’s UP/DOWN ARROW button again.
While the traveler is moving to the down position (toward
the door), block the safety beam. THE TRAVELER MUST
STOP, THEN REVERSE TO THE UP POSITION. The
operator’s light and red light should flash three times.
5Place an object in the path of the safety beam.
Check that constant pressure is required on the
wall station’s UP/DOWN ARROW button to cause the
traveler to move toward the down position. Release
the pushbutton before the operator stops; check that
the traveler returns to the up position.
NOTE: The garage door operator will not respond
to a CLOSE command from a radio transmitter if the
safety beam is blocked.
6 To reconnect the operator, flip the release lever up.
Raise the door manually until the operator reconnects.
NOTE: If the door remains idle for 5 minutes, the
beam light will turn off to save power. The beam
power turns on for 5 minutes when door moves down
to the fully closed position. The beam power can be
restored for 5 minutes by pressing the light button.
 WARNING 
Serious injury or death from a closing garage
door may result because of failure to test and
adjust safety reverse system. Repeat this test
monthly and adjust as needed.

operator can injure themselves or others. The
garage door could cause serious injury or death.
Do not allow children to operate the remote
control(s) or the wall station. A moving garage
door could injure or kill someone under it. Activate
the operator only when the door is clearly visible,
free of obstructions and adjusted properly.
1 Press the opener’s LEARN button until the opener’s
RED LED flashes once and the light turns on. A
remote must be added or removed while the light
is still on (15 seconds).
2 Press and hold the desired button on the remote. The
opener’s light and the RED LED will flash once if a
remote was added.
3 Repeat Steps 1 & 2 for any additional remote controls.
To Remove A Remote Control
1 If a remote is already programmed to the opener and
you want to delete it, follow the same procedure as
ADDING REMOTES above. The opener will recognize
the remote and delete it from memory. The RED LED
and LIGHT will blink 4 times to show the REMOTE
was successfully deleted.
To Remove All Remote Controls
1 Press and hold the operator’s LEARN button for
ten (10) seconds or more, then release the LEARN
button.
2 The RED LED and the operator’s light will flash 4
times indicating ALL remotes have been remove
from memory.
Testing The Remote
1 Before testing the remote control, straighten out the
operator’s antenna wire so it points up.
2 Stand clear of the door, press the remote control’s
button and verify that the operator starts. PRESS
THE REMOTE CONTROL’S BUTTON AGAIN TO STOP
THE DOOR MID-TRAVEL.
Replacing a Remote Control’s Battery
When the red light on the remote glows dimly, or fails
to light at all when the remote is activated, the battery
needs replacing.
1 Open the remote’s case and remove the circuit board.
2 Replace old battery with a Type CR2032 battery.
3 Re-assemble the remote.
The operator automatically measures the door force throughout the entire travel of the door each time the
operator cycles. The following steps are all that’s required to setup the safety reversal system.

IF A REMOTE IS REMOVED
The operator uses the peak force measured during each of the last four complete cycles plus a “force factor” to
calculate the maximum allowed force setting for the current door cycle. If the calculated maximum force setting
is exceeded during the current door cycle, the operator reacts to the obstruction. As door hardware conditions
change over time with weather and wear, the calculation of the maximum door force setting using the four cycle
running average will compensate for the current conditions of the installation.
The door force is preset for the lowest amount of pressure on an obstacle to detect an obstruction. THE
FACTORY SETTING IS OPTIMIZED FOR MOST INSTALLATIONS.
Changing the Force Factor Setting
As an installation option, the operator’s “force factor” can be adjusted to change the amount of pressure exerted
on an obstacle before the operator reacts to the obstruction.
1 Press both the UP and DOWN buttons for three seconds. The red and green indicators and operator’s light will
flash twice.
2 Use the UP or DOWN buttons to set the force factor. Pressing the UP button increases the force factor, pressing
the DOWN button decreases the force factor.
