OXYvisor Optical Oxygen Analyzer
Installation of the Junction Box:
1. Put the jam nut (B4711-1004) about 2/3 of the distance onto the exposed bushing threads. Apply a small
bead of Loctite 577 (B8008-1014) thread sealant to the rst two threads on the bushing around the full
perimeter. A nger may be used to smear the sealant to fully cover the rst two threads.
2. Carefully thread the junction box onto the bushing without damaging the ber optic cable or the RTD cable,
if applicable. If a sensor wand is used, fully extend the wand and gently thread it through the junction
box M24 hole and opposite 1/2” NPT hole. Screw the Junction Box onto the bushing with 5 to 7 full turns.
Leave the junction box opening facing the same direction as the opening of the big compartment on the
main enclosure. Apply a small drop of Loctite 577 thread sealant, or use excess from previous, to the rst
couple of exposed threads beyond the junction box interface. Secure the jam nut to the junction box and
tighten to approximately 25 foot-pounds of torque.
