c.
Mark the sensor cable routing from the sensor to the transmitter in the
Instrument/Solenoid Panel Box (see Figure 9 for the sensor and box locations).
d. Cut the tie wraps that secure the sensor cable along its routing from the sensor to the
transmitter.
e. Unscrew the ring nut from the panel box that the cable runs through.

f.
Disconnect the sensor outer shield wire from module TB2 and the sensor red, black,
inner shield, white, and blue wires from module TB3 at the back of the conductivity
transmitter CIT-501 (see Figure 10).
g. Pull the wiring through the panel box and remove the sensor and its cabling.
3. Clean the area where the sensor mounts and inspect for any condition that could cause leakage.
4. Install the new conductivity sensor as follows:
a. Position the gasket on the piping flange.
b. Insert the new sensor into the piping and position it against the gasket.
c. Secure the sensor and gasket to the flange using the sanitary clamp and tighten.
d. Rout the sensor cabling back through the cabling run that was marked earlier during
removal and secure the sensor cabling and the other cabling in the run with tie wraps.
e. Feed the sensor cabling through the ring nut and panel box.
