Also, what is the purpose of the manual valve just above the lower pressure gauge? It would seem to isolate the 'stored' and 'working' sides of the pneumatic system if closed. Inspectors may find issue with this due to R78. If this valve is ever closed, then opening the pressure vent plug would not relieve all stored pressure.

Thanks for the info. We will correct both problems that you have indicated.
