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

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.

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.
• Do you have an access door in addition to the
garage door? If not, Model 1702E 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 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 reinforce-
ment is required (Installation Step 10).
• 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 1.2 m to the left or right of
the door center. See Installation Steps 1 and 10.

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 10.
• Depending on your door’s construction, you may
need additional mounting hardware for the door
bracket (Step 10).
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 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 1
Determine the Header Bracket
Location
Installation procedures vary according to garage door
types. Follow the instructions which apply to your
door.
If your door is a canopy or dual-track style garage
door, a door arm conversion kit is REQUIRED.
Follow the installation instructions included with the
replacement door arm sectional.
SECTIONAL DOOR
AND ONE-PIECE DOOR WITH TRACK
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 1.2 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 17) when clearance is minimal. (It may be
mounted on the wall upside down if necessary,
to gain approximately 1 cm.)
If you need to install the header bracket on a
38 mm board (on wall or ceiling), use lag screws
(not provided) to securely fasten the 38 mm board
to structural supports as shown here and on
page 14.
3. Open your door to the highest point of travel as
shown. Draw an intersecting horizontal line on the
header wall 5 cm above the high point. This height
will provide travel clearance for the top edge of the
door.
Proceed to Step 2, page 15.
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 38 mm board 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 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 5 mm 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 T-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 38 mm board. 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.

To avoid possible SERIOUS INJURY from a falling
garage door opener, fasten it SECURELY to structural
supports of the garage. Concrete anchors MUST be used
if installing ANY brackets into masonry.

INSTALLATION STEP 6
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 21.
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 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 7
Install the Light and Lens
1. Install a 75 watt maximum light bulb in the socket.
Light bulb size should be A19. 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 A19, standard neck garage door opener bulbs
for replacement.
NOTE: Use only standard light bulbs. The use of
short neck or speciality light bulbs may overheat the
endpanel or light socket.
Install the lens
1. Locate and loosen (approximately 1/8" (3 mm)) the
two screws near top of opener front panel.
2. Position lens against panel with slotted tabs
directly below screws. Slide lens up to seat tabs
behind screws.
3. Snap bottom tabs of lens into panel slots.
4. Re-tighten top panel screws to secure lens.
INSTALLATION STEP 8
Attach the Emergency Release
Rope and Handle
1. Insert one end of the emergency release rope
through the handle. Make sure that “NOTICE” is
right side up. Tie a knot at least 1 inch (2.5 cm)
from the end of the emergency release rope.
2. Insert the other end of the emergency release
rope through the hole in the trolley release arm.
Mount the emergency release within reach, but at
least 6 feet (1.83 m) above the floor, avoiding
contact with vehicles to prevent accidental release
and secure with a knot.
Optional installation: As an added security option a
padlock may be installed on the trolley release arm.
To utilize this feature you must drill a hole
4.5 mm - 8 mm on the dimple which is located on the
trolley release arm. Install the padlock. When using
this feature the emergency release will not work until
the padlock is removed.
NOTE: If it is necessary to cut the emergency
release rope, seal the cut end with a match or lighter
to prevent unraveling. Ensure the emergency release
rope and handle are above the top of all vehicles to
avoid entanglement.
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.
