4. Check position of the arrow stamped on vane support
bracket. This arrow should be pointing parallel with the
flow arrow on the body bushing. Refer to Figure 7. If
arrows are not parallel, remove the three vane support
bracket mounting screws and rotate bracket until the
stamped arrow is pointing parallel with the flow arrow;
replace mounting screws.
2.3.1.3 Trimming Vane to Fit Horizontal Line Size
The F10 is furnished as standard with vanes suitable for
use on 2.00 inch through 30.00 inch pipelines. Assemble
vane (or vanes) to F10 and trim according to applicable
line size as follows:
2.00 inch line (Sch 40):
Use small vane only. No cutting should be
necessary.
2.50 inch line:
Use small vane, with large vane trimmed to
1.50 inches wide (same as small vane) and length
trimmed to dimension “C” less .19 inch (5 mm).
Refer to Figure 8.
3.00 inch line and up:
Use small vane, with large vane trimmed
to dimension “C” less .19 inch (5 mm). Refer to
Figure 8. Upon final assembly of trimmed vanes,
firmly tighten two screws.
It is recommended that the lower retaining screw
be peened over on the threaded end.
2.3.1.4 Final Mounting
1. Apply sealing compound to body bushing threads.
2. Thread F10 into threadolet fitting and tighten body bush-
ing to the same seal tight position so that the flow arrow
is pointing parallel with the line flow. Refer to item #1,
Section 2.3.1.2, Positioning Vane Perpendicular to Flow.
3. Connect conduit and power lines.
