Section 3
2. Temporarily position one of the frames on the pipe where you will be mounting it. Ensure that this is
a smooth area without any raised areas (seams, etc.) With a pencil or chalk, mark a generous area
around the frame (1/2" on either side and half again the length front and back). Remove the assem-
bly.
3. Prepare the area you marked by de-greasing surface, if needed, and removing any grit, corrosion,
rust, loose paint or surface irregularities with the abrasive material provided.
4. Put a mounting strap around the pipe and engage an end into adjusting screw (screw should be
pointing up). Position frame in the middle of area you have cleaned and centered on the pipe with its
angled end facing away from where the other frame will sit.

5. Slide the mounting strap over it (and under the clip if there is one) and tighten with a screwdriver.
While tightening, check to ensure that the center of the tapered roller is centered on the pipe.
6. Attach the second frame to the spacer bar with an index spacer screw into the index hole specified
in Step 1. The angle on the frame should be facing away from the direction the length of the bar is
going. Now attach the free end of the spacer bar by inserting an index spacer screw through the
REF hole on the spacer bar and then into the hole on the mounted frame. Tighten. Sight to ensure
that this frame is lined up in center of pipe and while holding alignment, place a dot (with pencil or
chalk) in the center of the tapered roller at the bottom of the frame (see A on next page). While
holding, also mark along the front edge of the frame with pencil or fine chalk line (see B on next
page).
7. Disassemble the spacer bar and the unmounted frame. Use the bar as a straight edge and, with
one edge against the mounted frames tapered roller center and the other crossing the dot you
drew, draw a line crossing the dot (see "B" on next page). Set the bar aside.
8. Wrap the Mylar Mounting Guide around the pipe so that the left edge is against the transducer edge
mark (see "C" next page). Arrange so that one end overlaps the other by at least three inches. Trim
to fit if necessary, but be sure not to trim at the overlapping end in order to keep it square.
