UNATTENDED OPERATION
Any device or feature that allows the door to close without being in the
line of sight of the door is considered unattended close. Devices that
allow unattended operation are to be used ONLY with sectional
doors.
PREPARING YOUR GARAGE DOOR
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 installation and operating garage door opener
to avoid entanglement.
•DO NOT install on a one-piece door if using devices or
features providing unattended close. Unattended devices and
features are to be used ONLY with sectional doors.
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.
Before you begin:
1. Disable locks and remove any ropes connected to the garage
door.
2. Lift the door halfway up. Release the door. If balanced, it
should stay in place, supported entirely by its springs.
3. Raise and lower the door to check for binding or sticking. If
your door binds, sticks, or is out of balance, call a trained door
systems technician.
4. Check the seal on the bottom of the door. 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.
5. 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 (1.2 m) to
the left or right of the door center. See page13.

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 12 – Depending upon garage construction,
extension brackets or wood blocks may be needed to install
sensors.
•Installation Step 12 – 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, an emergency key release is required.
•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 2. Floor or door
should be repaired.
SECTIONAL DOOR INSTALLATION
•Do you have a steel, aluminum, fiberglass or glass panel
door? If so, horizontal and vertical reinforcement is required
(Installation Step 8).
•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 8.
•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 8.
•Depending on your door’s construction, you may need
additional mounting hardware for the door bracket
(Installation Step 8).
Without a properly installed safety reversing sensor, 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.

ASSEMBLY STEP 1
ASSEMBLE THE RAIL AND INSTALL THE
TROLLEY
To prevent INJURY from pinching, keep hands and fingers away
from the joints while assembling the rail.
To avoid installation difficulties, do not run the garage door opener
until instructed to do so.
The front rail has a cut out “window” at the door end. The front rail has
a rail tab. This tab MUST be on the top of the rail when assembled.
1. Remove the straight door arm and hanging bracket packaged
inside the front rail and set aside for Installation Step 5 and 9.
NOTE: To prevent INJURY while unpacking the rail carefully
remove the straight door arm stored within the rail section.
2. Align the rail sections on a flat surface as shown and slide the
tapered ends into the larger ones. Tabs along the side will
lock into place.
3. Place the motor unit on packing material to protect the cover,
and rest the back end of the rail on top. For convenience, put
a support under the front end of the rail.
4. As a temporary stop, insert a screwdriver into the hole 10" (25
cm) from the front end of the rail, as shown.
5. Check to be sure there are 4 plastic wear pads inside the
inner trolley. If they became loose during shipping, check all
packing material. Snap them back into position as shown.
6. Slide the trolley assembly along the rail from the back end to
the screwdriver.
7. Slide the rail onto the “U” bracket, until it reaches all the stops
on the top and sides of the “U” bracket.
