Planning

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.

•Installation Step 10 - Depending upon garage construction, extension brackets or wood blocks

may be needed to install sensors.

•Installation Step 10-Alternate floor mounting of the safety reversing sensor will require hardware not provided.
