Model T17 Installation Guide

Chapter 4. Inserting T17 Transducers into the Pipe

4.2.2 Mounting the Insertion Mechanism (cont.)

Lift the gasket and insert the packing tool into the packing nut. By turning the packing tool clockwise, tighten
the packing material so that the barrel stays up without support (see

Figure 70

below).

Figure 70: Tightening the Packing Material

Place a gasket on the isolation valve (see
