STEP 3 Attach the Rail to the Header Bracket
1. Position the opener on the garage oor below the header bracket. Use packing material as a protective
base.
NOTE:I f the door spring is in the way, you will need help. Have someone hold the opener
securely on a temporary support to allow the rail to clear the spring.
2. Position the rail bracket against the header bracket.
3. Align the bracket holes and join with a clevis pin as shown.
4. Insert a ring fastener to secure.
STEP 4 Position the Garage Door Opener
1. Remove the packing material and lift the garage door opener onto a ladder.
2. Fully open the door and place a 2x4 (laid at) under the rail. For one-piece doors without tracks, lay the

NOTE: 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.
To avoid possible SERIOUS INJURY from a falling garage door opener, fasten it SECURELY to structural

STEP 5 Hang the Garage Door Opener
Hanging the garage door opener will vary depending on your garage. Below are three example installations.
Your installation may be dierent. For ALL installations the garage door opener MUST be connected to structural
supports. The instructions illustrate one of the examples below.
1. On nished ceilings, use the lag screws to attach a support bracket (not provided) to the structural supports
before installing the garage door opener.
2. Make sure the garage door opener is aligned with the header bracket. Measure the distance from each side
of the garage door opener to the support bracket.
3. Cut both pieces of the hanging bracket (not provided) to required lengths.
4. Attach the end of each hanging bracket to the support bracket with appropriate hardware (not provided).
5. Attach the garage door opener to the hanging brackets with the hex bolts, lock washers, and nuts.
6. Remove the 2x4 and manually close the door. If the door hits the rail, raise the header bracket.
Unnished Ceiling
To prevent possible OVER HEATING of the end panel or light socket:
l Use ONLY A19 light bulbs.
l DO NOT use incandescent bulbs larger than 100W.
l DO NOT use compact uorescent light bulbs larger than 26W (100W equivalent).
l DO NOT use halogen bulbs.
l DO NOT use short neck or specialty light bulbs.
LED bulbs may cause remote control radio interference. Use ONLY LED bulbs recommended here:
chamberlain.com/bulb.
or or or

To prevent possible SERIOUS INJURY or DEATH from a falling garage door:
l 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.
l NEVER use emergency release handle unless garage door way is clear of persons and obstructions.
l 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 sideup
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 oor, avoiding contact with vehicles to
prevent accidental release and secure with an overhand knot.
NOTE: If it is necessary tocut the emergency release rope, seal thecut end with a match or
lighter to prevent unraveling. Ensure the emergency release rope and handle are above the top of
all vehicles toavoid entanglement.

OPTION A - SECTIONAL DOORS
IMPORTANT: The groove on the straight door arm MUST face away from the curved door arm.
1. Close the door. Disconnect the trolley by pulling the emergency release handle.
2. Attach the straight door arm to the outer trolley using the clevis pin. Secure with the ring fastener.
3. Attach the curved door arm to the door bracket using the clevis pin. Secure with the ring fastener.
4. Bring arm sections together. Find two pairs of holes that line up and join sections. Select holes as far
apart as possible to increase door arm rigidity and attach using the bolts, nuts, and lock washers.
5. Pull the emergency release handle toward the garage door opener until the trolley release arm is
horizontal. The trolley will re-engage automatically when the garage door opener is activated.
