PCU Fire System Nozzles
The Overlapping Male Nozzle(s) (p/n OL-M) are used to protect the PCU.
The nozzles include a cap (p/n 3074-1-1).
Refer to Figure 45. The cap prevents contamination from entering the pipe network and is designed to pop-off
upon system discharge, allowing the fire system to flow to the protected hazard area.
