Before installation, fully extend the Hot Tap by loosening the
clamping collar (lock ring) screw (Figure 2-45) and pulling the
sensor all the way back inside the nipple, as shown at the bottom
left of Figure
2-44 .
Figure 2-45 Early HTI Hardware
The sensor’s extended length E is 2.25 inches greater than the
sensor length L . Use Figure 2-44 as a guide when calculating dis-
tances C and D .
Installation 1. With the sensor fully extended, apply pipe thread tape to
the nipple threads.
2. Screw the nipple into the valve.
3. Open the valve and push the sensor into the pipe to
Dimension I .
4.
Align the arrow printed on the sensor head box (bottom right,
Figure
2-44
) with the direction of flow (downstream). (The
cable is also attached on the downstream side of the box.)
Note
For highest accuracy, the box must be aligned exactly parallel
to the flow in the pipe, with the cable end facing downstream.
When adjusting this alignment, ROTATE THE SHAFT, not the
box itself.
