a. Fully retract the probe from the tubing union assembly and base.
b. Begin at the top of the tubing union assembly and measure up on the
shaft to the desired length.
c. Mark this point on the shaft, as this is where you will lock the assembly.
d. Move the tubing union assembly up on the shaft to the marked point.
e. Use an adjustable wrench to tighten the tubing nut onto the tubing union.
The ferrule will clasp onto the shaft, locking the assembly in place.
f. Loosen the nut and slide the base down until it stops.
Do not tighten the tube union to the base. The TFE ferrule is a back up to the
primary seal (O-ring), and should only be tightened if the primary seal or o-ring
leaks.
3. Cutting off excess tubing from the shaft
a. Measure up on the shaft approximately two inches from where the tubing
union assembly is now positioned. Mark this point on the shaft.
b. Using tubing cutters, remove the excess tubing from the two-inch mark on
the shaft.
c. File and smooth the cut edge of the shaft.
d. Thread valve “A” onto the shaft, making sure the valve is closed.
