Step 2: Mounting the Enclosure
A. Place the Enclosure assembly over the Keepers
and slip into place. You may be required to
align and manipulate the Keeper studs into
their respective holes. Be aware of Up-stream
vs. Down-stream. See Fig 2-1
mounting Direct-X Mode, maintain alignment of
Keepers as outlined in step "1-D" section "H".
Orient the enclosures so the fixed transducers of
both paths are located at the same end of the
pipe.)
B. Install retaining nuts at every Keeper location.
Tighten ONE end, just enough to keep assembly
from moving. Rock
perpendicular to the pipe, to allow the
assembly to find center. Tighten nut just enough
to keep assembly from moving. See Fig 2-2
(Note: When mounting Direct-X Mode, maintain
alignment of Keepers as outlined in step "1-D"
section "H".)
C. Visually verify the assembly to be in line with the
pipe axis by comparing the top edge of the
assembly to the linear axis of the pipe. Adjust if
necessary. See Fig 2-2
D. Tighten all retaining nuts just enough to keep
assembly from moving.
E. Repeat steps A through E for remaining paths.
F. Fully tighten all retaining nuts to approximately
20 – 25 in/lbs. Lock in place with second nut.
G. When you have mounted the enclosures and
fully tightened the retaining nuts you may now
install the middle strap. Simply feed the strap
through the center Keeper. Wrap around the
pipe twice and tighten as you did the previous
straps. See Fig 2-3 and 2-4
