Check the 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 16.

IMPORTANT INSTALLATION INSTRUCTIONS
To reduce the risk of SEVERE INJURY or DEATH:
1. READ AND FOLLOW ALL INSTALLATION WARNINGS AND INSTRUCTIONS.
2. Install garage door opener ONLY on properly balanced and lubricated garage door. An improperly
balanced door may NOT reverse when required and could result in SEVERE INJURY or DEATH.
3. ALL repairs to cables, spring assemblies and other hardware MUST be made by a trained door systems
technician BEFORE installing opener.
4. Disable ALL locks and remove ALL ropes connected to garage door BEFORE installing opener to avoid
entanglement.
5. Where possible, install the door opener 7 feet (2.13 m) or more above the floor.
6. Mount the emergency release within reach, but at least 6 feet (1.83 m) above the floor and avoiding
contact with vehicles to avoid accidental release.
7. NEVER connect garage door opener to power source until instructed to do so.
8. NEVER wear watches, rings or loose clothing while installing or servicing opener. They could be caught
in garage door or opener mechanisms.
9. Install wall-mounted garage control panel:
•within sight of the garage door.
•out of reach of small children at a minimum height of 5feet (1.5m) above floors, landings, steps
or any other adjacent walking surface.
•away from ALL moving parts of the door.
10. Place entrapment warning label on wall next to garage control panel in a prominent location.
11. Place emergency release/safety reverse test label in plain view on inside of garage door.
12. Upon completion of installation, test safety reversal system. Door MUST reverse on contact with a 1-
1/2" (3.8cm) high object (or a 2x4 laid flat) on the floor.
13. 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.
14. SAVE THESE INSTRUCTIONS.

16
Installation
1 Determine the Header Bracket Location
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 2x4 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.
Close the door and mark the inside vertical centerline of the garage door.
Extend the line onto the header wall above the door. You can fasten the header bracket within 4 feet (1.22 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 when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain
approximately 1/2" (1 cm). If you need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws
(not provided) to securely fasten the 2x4 to structural supports.
Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall
2" (5 cm) above the high point. This height will provide travel clearance for the top edge of the door.
NOTE: If the total number of inches exceeds the height available in your garage, use the maximum height
possible, or refer to page 17 for ceiling installation.

4 Position the Garage Door Opener
To prevent damage to garage door, rest garage door opener rail on 2x4 placed on top section of door.
1. Remove the packing material and lift the garage door opener onto a ladder.
2. Fully open the door and place a 2x4 (laid flat) under the rail.
A 2x4 is ideal for setting the distance between the rail and the door. If the ladder is not tall enough you will need
help at this point. If the door hits the trolley when it is raised, pull the trolley release arm down to disconnect the
inner and outer trolley. Slide the outer trolley toward the garage door opener. The trolley can remain
disconnected until instructed.

5 Hang the Garage Door Opener
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.
Hanging your garage door opener will vary depending on your garage. 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), 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"-18 x 1-7/8" lag screws (not provided).
5. Fasten the opener to the hanging brackets with 5/16"-18 x 7/8" hex bolts, lock washers and nuts.

6 Attach the Emergency Release Rope and Handle
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.
1. Insert one end of the emergency release rope through the handle. Make sure that “NOTICE” is right side
up. Secure with an overhand knot at least 1" (2.5 cm) from the end of the rope to prevent slipping.
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 floor, avoiding contact with vehicles to
prevent accidental release and secure with an overhand knot.
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.
