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. Open the captive screws on the connection box flange with a 5 mm (3/16 in) Allen key.
After loosening the captive screws, pull the connection box cover off to access the wiring
terminals.
If necessary, use a wrench to hold the probe in place by gripping the
tightening nut.
3. Pull the connection box cover open to access the wiring terminals.
