Identify the type and height of your garage door. Survey your garage area to see if any of the conditions below apply to your installation. Additional materials may be required. You may find it helpful to refer back to this page and the accompanying illustrations as you proceed with the installation of your opener.
Depending on your requirements, there are several installation steps which may call for materials or hardware not included in the carton.
•Installation Step 1 – Look at the wall or ceiling above the garage door. The header bracket must be securely fastened to structural supports.
•Installation Step 5 – Do you have a finished ceiling in your garage? If so, a support bracket and additional fastening hardware may be required.
•Do you have an access door in addition to the garage door? If not, Model 1702E Outside Quick Release is required. See Accessories page.
•Look at the garage door where it meets the floor. Any gap between the floor and the bottom of the door must not exceed 6 mm. Otherwise, the safety reversal system may not work properly. See Adjustment Step 3. Floor or door should be repaired.
SECTIONAL DOOR INSTALLATIONS•Do you have a steel, aluminum, fiberglass or glass panel door? If so, horizontal and vertical reinforce- ment is required (Installation Step 10).
•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 1.2 m to the left or right of the door center. See Installation Steps 1 and 10.
