anybody have a schematic for air tanks? (was: i have a question)

Use the schematic on page 11 of http://www2.usfirst.org/2007comp/oth...s%20Manual.pdf

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. EDIT: You may NOT remove the nason pressure switch, as per R101. Thanks to those below who caught my oversight. R103 also insists that the compressor be controlled VIA Spike by the RC.
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). EDIT: Control this using the NASON pressure switch and the program on your RC. 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 your pressure relief valve. EDIT: Generally pressure relief valves do not need adjusting, and are not allowed to be adjusted from their set point.

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

You have a charged pneumatic system.

Good luck, and have fun,
