SECTIONAL Door Installation
Before you begin, survey your garage area to
see whether any of the conditions below apply
to your installation.
Horizontal and vertical reinforcement
is needed for lightweight garage doors
(fiberglass, steel, aluminum, door with glass panels, etc.).
See page 24 for details.
Header Wall
FINISHED CEILING
Support bracket &
fastening hardware
is required.
See page 20.

Floor must be level
across width of door
Safety Reversing Sensor
Based on your particular requirements, there are several
installation steps which might call for materials and/or
hardware not included in the carton.
• Step 1, page 12 - Look at the wall or ceiling above the
garage door. The header bracket must be securely
fastened to structural supports.
• Safety reversing sensor, page 16 - Depending upon
garage construction, wood blocks may need to be
fastened to mounting locations before sensors are
installed.
• Step 4, page 17 - Alternate floor mounting of the safety
reversing sensor will require hardware not provided.
• Step 6, page 20 - Do you have a finished ceiling in your
garage'? If so, a support bracket and additional fastening
hardware may be required.
• Step 12, page 24 - Do you have a steel, aluminum,
fiberglass or glass panel door'? If so, horizontal and
vertical reinforcement is required.
• Look at the garage door where it meets the floor. It
must close on the floor all the way across. Otherwise,
the safety reverse system may not work properly. See
page 30. Floor or door should be repaired.

contents onto a level work surface.
2. Unfold the rails, taking care to avoid kinking the screw
rod joints.
3. Rotate the rail sections so that the flat side is down and
the screw side is up for all three lengths. Keep it clean
and free of debris while you are working.

4. Beginning with the sprocket end, straighten the two
rail sections so that the screw rod is in a straight line at
the joint. (Avoid handling the joints, which may have
sharp edges.)
5. Carefully slide the pins at the top edge of the rail into
the openings on the adjacent rail. It is essential that
the rail assembly be on a level smfaee to achieve
proper alignment and to aw_id damage to the pins.
6. Insert two 1/4"-20xl-3/4" bolts through the center
holes of a brace, and place its open length against the
rail at this joint, aligning the holes as shown. Position
another brace on the opposite side of the rail over the
bolts, add 1/4"-20 lock nuts, and hand tighten. Insert
two additional bolts and hand tighten.

You have now finished assembling your garage door opener. Please read the following warnings
before proceeding to the installation section:
IMPORTANT INSTALLATION INSTRUCTIONS
To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS
2. Install only on a properly balanced and lubricated garage door. An improperly balanced door may not
reverse and could result in severe injuly or death. Repairs to cables, spring assemblies and other hardware
must be made by a professional service person before installing opener.
3. Disable all locks and remove all ropes connected to the garage door before installing the opener. Ropes
connected to a garage door can cause entanglement and death.
4. If possible, install door opener 7 feet or more above floor with the emergency release handle mounted 6
feet above the floor.
5. Do not connect the opener to power source until instructed to do so.
6. Locate the Door Control within sight of the door at a minimum height of 5 feet where small children
cannot reach and away from all moving parts of the door.
7. Install the User Safety Instruction Label on the wall adjacent to the control button and the Maintenance
Instruction Label in a prominent location on the inside of the garage door.
8. Upon completion of the installation, the door must reverse when it comes in contact with a one-inch high
object or a 2x4 laid flat on the floor.
9. Do not wear watches, rings or loose clothing while installing or servicing an opener. Jewelry or loose
clothing can be caught in the mechanism of the garage door or the opener.

• Close the door and mark the inside
vertical centerline of the garage door.
• Extend the line onto the header wall
above the door.
Remember, you can fasten the header
bracket within 2 feet 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
(refer to page 14) when clearance is
minimal. (It may be mounted on the
wall upside down if necessary, to gain
approximately 1/2".)
If you need to install the header bracket on
a 2x4 (on waft or ceiling), use lag screws
(not supplied) m securelyJasten the 2x4 m
structural supports as shown here and on
page 13.
• Open your door to the highest point of
travel as shown. Draw an intersecting
horizontal line on the header wall 3"
above the high point. This height will
provide travel clearance for the top edge
of the door.
Highest Point
of Travel
Door clearance brackets are available
for sectional doors when headroom
clearance is less than 2". See accessory
page 38.
