This garage door opener has been designed
and tested to offer safe service provided it is
installed, operated, maintained and tested in
strict accordance with the instructions and
warnings contained in this manual.

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 (1.2 m) to the left or right of
the door center. See Installing the Header
