Unattended Operation
The Timer-to-Close (TTC) feature, the MyQ® Smartphone Control app, and MyQ® Garage Door and Gate Monitor are examples of unattended close and are to be used ONLY with sectional doors. Any device or feature that allows the door to close without being in the line of sight of the door is considered unattended close. The Timer-to-Close (TTC) feature, the MyQ® Smartphone Control, and any other MyQ® devices are to be used ONLY with sectional doors.
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 inch (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 12.

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 rail tab MUST be on 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 in the second rail section from the motor unit, 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 toward the screwdriver as shown.
7.Slide the rail onto the “U” bracket, until it reaches all the stops on the top and sides of the “U” bracket.

STEP 2 Fasten the rail to the motor unit
To avoid SERIOUS damage to garage door opener, use ONLY those bolts/fasteners mounted in the top of the opener.
1.Insert a 1/4"-20 x 1-3/4" bolt into the cover protection bolt hole on the back end of the rail as shown. Tighten securely with a 1/4"-20 lock nut. DO NOT overtighten.
2.Remove the bolts from the top of the motor unit.
3.Use the carton to support the front end of the rail.
4.Place the “U” bracket, flat side down onto the motor unit and align the bracket holes with the bolt holes.
5.Fasten the “U” bracket with the previously removed bolts; DO NOT use any power tools. The use of power tools may permanently damage the garage door opener.

STEP 3 Install the idler pulley
1.Lay the belt beside the rail, as shown. Grasp the end with the hooked trolley connector and pass approximately 12" (30 cm) of belt through the window. Keep the ribbed side toward the rail, and allow it to hang until Assembly Step 4.
2.Remove the tape from the idler pulley. The inside center should be pre-greased. If dry, regrease to ensure proper operation.
3.Place the idler pulley into the window as shown.
4.Insert the idler bolt from the top through the rail and pulley. Tighten with a 3/8" lock washer and nut underneath the rail until the lock washer is compressed.
5.Rotate the pulley to be sure it spins freely.
6.Locate the rail tab. The rail tab is between the idler bolt and the trolley in the front rail section. Use a flathead screwdriver and lift the rail tab until the tab is vertical (90º).

2.Hook the trolley connector into the retaining slot on the trolley as shown (Figure 1).
3.With the trolley against the screwdriver, dispense the remainder of the belt along the rail length toward the motor unit and around the sprocket (Figure 2). The sprocket teeth must engage the belt.
4.Check to make sure the belt is not twisted. Connect the trolley threaded shaft with the master link (Figure
3).
• Push pins of master link bar through holes in end of belt and trolley threaded shaft. • Push master link cap over pins and past pin notches.
• Slide the closed end of the clip-on spring over one of the pins. Push the open end of the clip-on spring
onto the other pin.
5.Remove the spring trolley nut from the threaded shaft.
6.Insert the trolley threaded shaft through the hole in the trolley.

STEP 3 Attach the rail to the header bracket
1.Position the opener on the garage floor below the header bracket. Use packing material as a protective base.
NOTE: If 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
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. For one-piece doors without tracks, lay the 2x4 on it's side.
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.

STEP 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 the garage door opener will vary depending on your garage. Below are three example installations. Your installation may be different. For ALL installations the garage door opener MUST be connected to structural supports. The instructions illustrate one of the examples below.
1.On finished 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 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.
