Remove the compressor package, and just plug the end of the Clippard Air Receiver Cylinder to which it is attached. You may also remove the Nason Pressure Switch.

Now you have a FIRST-Legal pneumatic circuit. To charge the system, connect your compressor's output to the Parker System Pressure Vent Valve (with a piece of tubing and a quick connect... remember to attach the pressure relief valve to the compressor before you do anything with it!). Open the Pressure Vent Valve. Run the compressor until the system is charged (120 psi). If you don't reach 120 psi you may need to adjust the pressure relief valve on the compressor... if you exceed 120 psi, you will DEFINITELY need to adjust you pressure relief valve.

Turn off the compressor, close the vent valve. Detach the compressor.

You have a charged pneumatic system.

You might have trouble with this setup, I seem to recall that we did this last year and needed to make some changes to pass inspection. We used the pressure switch to tell the controller to turn on a spike when pressure was below 120 psi (or whatever it is set at), then connected the spike to the compressor with quick connect terminals. We had to add a TEE and another manual valve to discharge the air from the compressor to manual valve hose, so we could safely release the pressure before disconnecting the compressor hose.

I may be wrong on the details....but the point is that the system you described might not pass inspection at all events, so be prepared to do it differently.
