Installing a Garage Door Opener

garage door opener assembly kit (appropriate tools vary with kit)
ratchet set
pliers
wire cutters (to remove wire sheathing)

Steps:

1. Spread all the separate parts of the kit in front of you.

3. Attach the rail clamps where appropriate to the rail sides, then slide the slide carriage into the carriage slot from the end of the rail. Next attach the rail straps to the end of the rail section.

4. With the rail section complete, install the limit switch wires into the groove of the rail assembly (figure B) and attach the two limit switches. The first switch is placed about six inches from the end of the gray wire and the second about a foot from the end of the rail assembly. Finally, attach the emergency release knob (figure C). * Note: Use these instructions as a general guide and always stick to the manufacturer's directions where appropriate.

5. Center the header bracket above the door and attach it to the wall (figure D). Attach the power unit to the ceiling (figure E). Attach the bracket to the door with lag screws.

6. Insert the door arm and hold it in place with a clevis pin. Next, attach the other door arm to the traveler, again with a clevis pin (figure F). Overlap the door arms that run between the traveler (slide carriage) and the garage door and secure with two bolts.

7. Installing the switch is a simple matter of finding outlet wire, revealing the sheathing of red and white wire, attaching the exposed wire to the switch, then screwing the switch into the wall. Attach door sensors to either side of the garage door (figure G).

8. Once you've run the wiring to the ceiling and plugged in the power unit, you are ready to go. This project costs around 200 dollars and takes about three hours.
