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 12 – Depending upon garage construction, extension
brackets or wood blocks may be needed to install sensors.
• Installation Step 12 – Alternate floor mounting of the safety reversing
sensor will require hardware not provided.
• Do you have an access door in addition to the garage door? If not, an
emergency key release is required.
• Look at the garage door where it meets the floor. 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. See Adjustment Step 2. Floor
or door should be repaired.

SECTIONAL DOOR INSTALLATION
• Do you have a steel, aluminum, fiberglass or glass panel door? If so,
horizontal and vertical reinforcement is required (Installation Step 8).
• 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 (1.22 m) to the left or right of the door
center. See Installation Steps 1 and 8.
• If your door is more than 7 feet (2.13 m) high, see rail extension kits listed
on Accessories page.
