To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and
operating the opener.
• ONLY operate garage door opener at 120V, 60 Hz to
avoid malfunction and damage.
To prevent possible SERIOUS INJURY or DEATH:
• ALWAYS call a trained door systems technician if
garage door binds, sticks or is out of balance. An
unbalanced garage door may NOT reverse when
required.
• NEVER try to loosen, move or adjust garage door,
door springs, cables, pulleys, brackets or their
hardware, ALL of which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected
to garage door BEFORE installing and operating
garage door opener to avoid entanglement.
Preparing your garage door
Before you begin:
• Disable locks.
• Remove any ropes connected to garage door.
• Complete the following test to make sure your garage
door is balanced and is not sticking or binding:
1. Lift the door about halfway as shown. Release the
door. If balanced, it should stay in place, supported
entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.

SECTIONAL DOOR INSTALLATION
Planning
Identify the type and height of your garage door. Survey
your garage area to see if any of the conditions below
apply to your installation. Additional materials may be
required. You may find it helpful to refer back to this page
and the accompanying illustrations as you proceed with
the installation of your opener.
Depending on your requirements, there are several
installation steps which may call for materials or hardware
not included in the carton.
• Installation Step 1 – Look at the wall or ceiling above
the garage door. The header bracket must be securely
fastened to structural supports.
• Installation Step 5 – Do you have a finished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
• Installation Step 10 – Depending upon garage
construction, extension brackets or wood blocks may
be needed to install sensors.
• Installation Step 10 – Alternate floor mounting of
the safety reversing sensor will require hardware not
provided.
• Do you have an access door in addition to the garage
door? If not, Model 1702LM Outside Quick Release is
required. See Accessories page.
• Look at the garage door where it meets the floor. Any
gap between the floor and the bottom of the door must
not exceed 1/4" (6 mm). Otherwise, the safety reversal
system may not work properly. See Adjustment Step 3.
Floor or door should be repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforcement
is required (Installation Step 11).
• The opener should be installed above the center of the
door. If there is a torsion spring or center bearing plate
in the way of the header bracket, it may be installed
within 4 feet (1.22 m) to the left or right of the door
center. See Installation Steps 1 and 11.
• If your door is more than 7 feet (2.13 m) high, see rail
extension kits listed on Accessories page.

Planning (Continued)
ONE-PIECE DOOR INSTALLATIONS
• Generally, a one-piece door does not require
reinforcement. If your door is lightweight, refer to the
information relating to sectional doors in Installation
Step 11.
• Depending on your door’s construction, you may need
additional mounting hardware for the door bracket
(Step 11).
Without a properly working safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• The gap between the bottom of the garage door and
the floor MUST NOT exceed 1/4" (6 mm). Otherwise,
the safety reversal system may NOT work properly.
• The floor or the garage door MUST be repaired to
eliminate the gap.

INSTALLATION STEP 5
Hang the Opener
Two 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 (not provided).
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.

Install the Door Control
Locate the door control within sight of the door at a
minimum height of 5 feet (1.5 m) where small children
cannot reach, and away from all moving parts of the door
and door hardware.
1. Strip 1/4" (6 mm) of insulation from one end of the bell
wire. Connect it to the two screw terminals on the back
of the door control by color: white wire to 2 and white/
red wire to 1.
2. Fasten the Lighted Door Control Button securely with
6ABx1-1/2" screws. If installing into drywall, drill 5/32"
holes and use the anchors provided.
3. Run the bell wire up the wall and across the ceiling to
the opener. Use insulated staples to secure the wire
in several places. Do not pierce wire with a staple,
creating a short or open circuit.
4. Receiver terminal screws and the antenna are located
on the back panel of the opener. Position the antenna
wire as shown.
5. Connect the bell wire to the opener terminal screws:
white to 2 and white/red to 1.
6. Use tacks or staples to permanently attach the
entrapment warning label to the wall near the door
control, and the manual release/safety reverse test in a
prominent location on the inside of the garage door.
NOTE: 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. See Safety
Reversing Sensor instructions beginning on page 19.

INSTALLATION STEP 7
Install the Light and Lens
INSTALL THE LIGHT
• Install an A19 standard neck, 75 watt maximum light
bulb in the socket. The light will turn ON and remain
lit for approximately 4-1/2 minutes when power is
connected. Then the light will turn OFF.
• Use standard neck Garage Door Opener bulbs for
replacement
INSTALL THE LENS
• Locate and loosen (approximately 1/8" (3 mm) the two
screws near top of opener front panel.
• Position lens against panel with slotted tabs directly
below screws. Slide lens up to seat tabs behind
screws.
• Snap bottom tabs of lens into panel slots.
• Retighten top panel screws to secure lens.
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. 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 OVERHEATING of the endpanel or
light socket:
• DO NOT use short neck or specialty light bulbs.
• DO NOT use halogen bulbs. Use ONLY incandescent.
To prevent damage to the opener:
• DO NOT use bulbs larger than 75W.
• ONLY use A19 size bulbs.
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.

INSTALLATION STEP 9
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.
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.
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.

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 (Figures 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.
