To prevent possible SERIOUS INJURY or DEATH:
• Header bracket MUST be RIGIDLY fastened to structural
support on header wall or ceiling, otherwise garage door
might not reverse when required. DO NOT install header
bracket over drywall.
• Concrete anchors MUST be used if mounting header
bracket or 2x4 into masonry.
• NEVER try to loosen, move or adjust garage door, springs,
cables, pulleys, brackets, or their hardware, all of which are
under EXTREME tension.
• ALWAYS call a trained door systems technician if garage
door binds, sticks, or is out of balance. An unbalanced
garage door might not reverse when required.
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 feet
(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.

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.
To avoid possible SERIOUS INJURY from a falling garage
door opener, fasten it SECURELY to structural supports of

INSTALLATION STEP 6
Install the Control Console
Locate control console within sight of door, at a minimum
height of 5' (1.5 m) where small children cannot reach,
away from moving parts of door and door hardware. If
installing into drywall, drill 5/32" holes and use the
anchors provided. For pre-wired installations (as in new
home construction), it may be mounted to a single gang
box (Figure 1).
CAUTION: Continuous exposure of the control console
to temperatures below –22° F (–30° C) may damage the
LCD screen.
NOTE: The functional temperature range of the control
console is between –4° F (–20° C) and 122° F (50° C).
Scroll speed of the display is slower at lower
temperatures although the control console remains fully
functional.
SPECIAL NOTE: Only one 398LMC can be connected to
each garage door opener. If additional wall controls are
desired to operate the same garage door opener, it is
recommended to use model 378LMC wireless wall
control as the secondary control console.
1. Strip 7/16" (11 mm) of insulation from one end of bell
wire and connect to the two screw terminals on back of
control console by color: white wire to the W (2) and
white/red wire to the R (1) (Figure 2).
2. Remove push bar cover by gently prying at the lower/
middle portion of the cover with a small flat-head
screwdriver. Fasten with 6AB x 1-1/4" self-tapping
screws (drywall installation) or 6-32 x 1" machine
screws (into gang box) as follows:
• Install bottom screw, allowing 1/8" (3 mm) to protrude
above wall surface.
• Position bottom of control console on screw head and
slide down to secure. Adjust screw for snug fit.
• Drill and install top screw with care to avoid cracking
plastic housing. Do NOT overtighten.
• Replace cover by inserting top tabs first and then
snap cover in place.
3. (For standard installations 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 on the
motor unit: white to white and white/red to red
(Figure 3).
NOTE: If you have any trouble with the operation of the
buttons, loosen the top mounting screw. DO NOT
connect the power and operate the 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.
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.

INSTALLATION STEP 8
Attach the Emergency Release Rope and Handle
• 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 release arm of the outer trolley.
• Adjust rope length so the handle is 6 feet (1.83 m)
above the floor. Ensure that the rope and handle clear
the tops of all vehicles to avoid entanglement. Secure
with an overhand knot.
NOTE: If it is necessary to cut the rope, heat seal the cut
end with a match or lighter to prevent unraveling.
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.

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.

INSTALLATION STEP 10
Install The Protector System
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

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.

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 quickconnect holes: white to white and white/black to grey
(Figure 6).
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.
Figure 5MOUNTING AND WIRING THE SAFETY REVERSING
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.

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.
Fiberglass, aluminum or lightweight steel garage doors will
require reinforcement BEFORE installation of door bracket.
Contact your door manufacturer for reinforcement kit.

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.

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.

Limit Adjustment Screws
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.
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" 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.
• 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
ADJUSTMENT STEP 2
Adjust the Force
Force adjustment controls are located on the right 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.
