SECTIONAL DOOR
ONE-PIECE DOOR
An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service.
Garage doors, door springs, cables,
pulleys, brackets and their hardware are under
extreme tension and can cause serious injury
or death.
Do not try to loosen, move or adjust
them yourself!
Ropes left on a garage door could cause
someone to become entangled and killed.
Remove all ropes connected to the door before
installing and operating the opener.
To avoid damage to the garage door and
opener, disable locks before installing and
operating the opener. Use a wood screw or nail
to hold locks in the "open" (unlocked)
position.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
Identify the type and height of your door and any
special conditions that exist and any additional
materials that may be required by referring to the lists
on page 4 or page 5.
Before you begin, complete the following test to
make sure your door is balanced, and is not
sticking or binding:
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.

Before you begin, survey your garage area to
see whether any of the conditions below apply
to your installation.
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.
• Step 5, page 17 - Do you have a finished ceiling in
your garage? If so, a support bracket and
additional fastening hardware may be required.
• Safety reversing sensor, page 21 - Depending
upon garage construction, wood blocks may need
to be fastened to mounting locations before
sensors are installed.
• Step 10, page 22 - Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.
• Step 11, 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.
SECTIONAL Door Installation
Closed Position
• An 8 foot high door will require Item No. 18754 Rail
Extension Kit. A 10 foot high door will require Item
No. 18753 Rail Extension Kit.
• The opener can be installed within 2 feet to the left
or right of the door center if there is a torsion spring
or center bearing plate in the way of the header
bracket or door bracket area.
If your door has
extension springs, the opener must be installed
in the center of the door.
See pages 12 and 24.
• Do you have an access door in addition to the
garage door? If not, Model 18752 Outside
Trolley Release is required. See page 38.

Assembly Step 1
Assemble the T-rail &
Attach the Belt Pulley Bracket
• Place the 3 T-rail sections on a flat surface for
assembly. The end sections are identical. Make
sure the "arrow label" on the center section is
pointing toward the door.
• Insert the carriage bolts so the square bolt necks
seat in the square holes in the T-rail end sections
and pass through the round holes in T-rail center
section. Assemble lock nuts, ensure alignment and
tighten.

• Position the belt pulley bracket on the front end of the
T-rail as shown. Fasten securely with the hardware
shown.
Make sure bolt necks are
seated in the square
holes and rails are
aligned before you
tighten lock nuts. (See
right and wrong views).
Improper assembly can
cause jerky trolley
operation, noise and/or
nuisance door reversals.
Right Wrong
Assembly Step 2
Install the Trolley on the T-rail
• Place the opener on packing material to protect the
cover. For convenience, put a support under the
belt pulley bracket.
• Remove the (2) 5/16"-18x1/2" washered screws
mounted in the top of the opener.
• Align the holes in the back section of the T-rail with
the holes in the opener.
• Fasten the rail with the (2) washered screws
previously removed. Tighten securely.
Remember to use only these screws!
Any other
screws will cause serious damage to the opener.
• Insert a 5/16"-18x7/8" hex screw into the cover
protection bolt hole in the T-rail as shown. Tighten
securely with a 5/16" lock washer and nut.
NOTE: This screw prevents trolley over-travel.
Keep a 2" minimum between the trolley and this
screw when adjusting travel limits (see page 28).

• As a temporary stop, insert a screwdriver into the
hole in the front end of the T-rail.
• Slide the trolley assembly along the rail to the
screwdriver stop.
If trolley hits against any nuts on the T-rail, the
bolts and nuts were attached from the wrong
side and must be repositioned. Review Step 1.
• Insert a 5/16"-18x7/8" hex screw into the trolley
stop hole in the T-rail as shown. Tighten securely
with a 5/16" lock washer and nut. This screw limits
trolley travel in the DOWN direction.

IMPORTANT INSTALLA TION 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 injury 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 door control 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.

• Open your door to the highest
point of travel as shown. Draw
an intersecting horizontal line
on the header wall 2" above
the high point. This height will
provide travel clearance for the
top edge of the door.
Door clearance brackets are
available for sectional doors
when headroom clearance is
less than 2". See accessory

• 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 wall or ceiling), use lag
screws (not supplied) to securely fasten
the 2x4 to structural supports as shown
here and on page 13.

Installation Step 1
Determine Header Bracket Location
Installation procedures vary according to
garage door types. Follow the instructions
which apply to your door.
If the header bracket is not rigidly fastened to
a structural support on the header wall or
ceiling, the safety reverse system may not
work properly (see page 30).
The door might
not reverse when required, and could cause
serious injury or death.
The garage door springs, cables, pulleys,
brackets and their hardware are under extreme
tension.
Do not attempt to loosen, move or
adjust them yourself. Serious personal injury
or death could result.
Call for professional
garage door service.
