Step 1. Install to process valve
}
Be sure the ball valve to the process line is closed
}
Apply a thread sealant, such as Teflon
®
Tape, to the male threads on the bottom of the probe
}
Install the probe into the process ball valve using a 1-3/8” open end wrench
ONLY
on the lowest wrench flats on the base, nearest to the NPT
male threads (see Figure 1)
Step 2. Pressurize the probe
}
Be sure the vent valve in the auxiliary port is closed (see Figure 1)
}
Slowly open the ball valve to the process (see Figure 2)
Step 3. Lowering the probe to proper depth
}
Decide the depth needed for the probe (D1) by determining from the top of the full port process ball valve to the desired end of the probe in
the pipeline (see Figure 4)
}
Apply the depth (D1) to the probe from the top of the base up the threaded rod to determine the lowering stopping point (see Figure 3)
}
Install the 2 depth marking nuts on the threaded rod at the predetermined lower stopping point. Using 2 7/8” open end wrenches, rotate the
upper nut clockwise and the lower nut counterclockwise simultaneously until the nuts are locked firmly in place.
}
Lower the probe to the proper depth by using a 7/16” open end wrench only on the wrench flats of the threaded rod of the probe (Figure 5).
Step 4. Leak testing the probe connections
}
Using a leak detector, check for leaks at the following locations: process connection, probe packing seal, and additionally any other
connection made during the probe installation.
}
If leaking occurs through the probe packing gland, use a 1 3/16” open end wrench to tighten the packing seal plug until the leak stops. DO
NOT OVERTIGHTEN.
