Model T17 Installation Guide

5.2 Using the Insertion Mechanism (cont.)

Install a new flange gasket on the isolation valve. Then, fasten a

“blind”

flange onto the isolation valve with

the bolts removed in the previous step (see

Figure 92

below).

Figure 92: Installing a Blind Flange

Disconnect the junction box on the end of the transducer by loosening the compression fitting.

Repeat the process to remove the other transducer.
