BEFORE YOU BEGIN:
1. Look at the wall or ceiling above the garage door. The header bracket must be securely fastened to structural

2. Do you have a finished ceiling in your garage? If so, a support bracket and additional fastening hardware (not
supplied) may be required.
3. Depending on your door's construction, you might need a special door arm. See your dealer.
4. Do you have an access door in addition to the garage door? If not, Model 1702E Outside Quick Release
Accessory is required. This accessory allows manual operation of the garage door from outside in case of
power failure.
