Procedure
1. Securely connect the ball valve assembly (ball valve, nipple,
and reducer) to the process.
2. Make sure the ball valve is closed and the system pressure is
at or below the maximum rated retraction pressure for the
sensor length you are using before proceeding.
3. Slide the ferrule fitting (PN 23166-00 or 23166-01) onto the
sensor from the back of the sensor.
4. With the ferrule fitting on the sensor's body, insert the sensor
into the ball valve until it gently touches the closed valve.

WARNING
Before removing the sensor, be absolutely certain that the
process pressure is reduced to 0 psig (0 barg) and the
process temperature is lowered to a safe level.
Do not insert or retract retractable sensors when process
pressure is above the specified retraction pressure limit for
the length of sensor being used.
For 21-in. (533 mm) length sensors the maximum allowed
retraction pressure is 64 psig (5.4 barg).
For 36-in. (914 mm) length sensors the maximum allowed
retraction pressure is 35 psig (3.4 barg).
