Wattsun AZ-225 Installation Manual page 7

VERY IMPORTANT! "OUT OF THE BOX" DRIVE ORIENTATION
The AZ-225 Drive orientation is preset at the factory and referenced to Solar Noon. The drive should
be mounted facing due South, (Due North in the Southern Hemisphere.). The four set bolts "dig in" to
the mounting pipe and secure the drive to the pipe mast.
SET BOLTS: The 4 "cup point" set bolts "dig and cut" in to the 8" ID SCH40 Steel Pipe Mast. Tighten
the set bolts so that they put strong and equal pressure on the pipe mast. Each bolt should "show"
and equal amount of thread when you are finished
Lbs of torque.
ROLL PIN: A three-eighths inch (3/8") diameter hole is predrilled in the midpoint of the south face of
the drive. The hole accommodates the 3/8" roll pin. Once you are sure that the drive is facing due
South, you can use the hole as a guide to drill a three-eighths inch (3/8") diameter hole into and
through the wall of the mounting pipe. Then tap in the roll pin so that it penetrates through both the
drive and pipe mast. Alternately, both holes could be threaded and a bolt could be used to "pin" the
drive and mounting pipe together.
Each set bolt should be tightened to 100 Ft-
.
J -BOX & OTHER EQUIPMENT ON THE MOUNTING POLE: Any
equipment that will be mounted on the pipe mast should be located
on the North side (opposite of the roll pin hole), at least one foot
down from the top of the pipe. That allows for our sleeve to fully
seat on the pipe and that nothing physically interferes with the
tracker range of motion.
