ChecktheDoorTo prevent possible SERIOUSINJURYor DEATH:

lALWAYS 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.

lNEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their

hardware, ALLof which are under EXTREME tension.

lDisable ALLlocks and remove ALLropes connected to garage door BEFORE installation and operating

garage door opener to avoid entanglement.

lDO 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:

lALWAYS disable locks BEFORE installing and operating the opener.

lONLY 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

Preparation

AssemblySTEP1AssembletheRailandInstalltheTrolleyTo 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.
