3.7 Hot-Tap Installation
1. Thread one hex nut onto each of the three
threaded rods included in package. Install
threaded rod with a lock-washer onto the brass
sensor nut. Secure rods in place by tightening
each hex nut against the brass sensor nut.
2. Thread one jam nut and lower hex nut onto
each stud so the top surface of each nut is 13.75
in. (350 mm) from top surface of brass sensor nut.
Secure each hex nut with a jam nut.
This setting is critical to ensure an adequate
sensor seal and to prevent the rotor from hitting
the isolation valve orifice during installation.
