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 first two threads on the bushing around the full
perimeter. A finger may be used to smear the sealant to fully cover the first two threads.
2.
Carefully thread the junction box onto the bushing without damaging the fiber 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 first
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.
