3.3 Inserting Probe into Process and Opening
Connection Box
1. Insert the probe into the 1.5" female NPT installation port and rotate it clockwise until it
sits firmly in the port. Do not tighten the probe to full tightness, only enough to keep it
securely in place when wiring.
Rotating the probe open (counter-clockwise) after it has been
installed into the port can tear the PTFE tape. Only adjust the position of
the probe in the installation port by tightening (rotating clockwise).
CAUTION!
2. Hold the probe by gripping the tightening nut with a wrench. Then open the connection
box cover by turning the cover counter-clockwise with the connection box key.
For easier access, loosen the cable glands and insert the wiring cables into
the connection box before pulling the connection box cover open.
3. Pull the connection box cover open to access the wiring terminals.
