Connect your regulator after the reserviors. Be sure it is set with the flow in the right direction (arrow away from your compressor).

The control system, thru the pressure switch, keeps the reservior side limited to about 115 - 120 psi. You must have a pressure gage before the regulator to show that you are staying below 120 psi. Put another pressure gage after the regulator and adjust the regulator to 60 psi max.

You do not have to use both regulators. The second one is an option if youwant to use two different regulated pressures. For example, one cylinder at 60 psi and another at 40 psi.

Take a good look at the pictures in the FIRST manual - they have detail and show a workable circuit.
