Hook it up, swirl like crazy for several minutes, and then leave it hooked up. As the CO2 goes into solution you want to keep the pressure constant. After 36-48 hours you will probably be at saturation for the pressure you have selected and then you can disconnect and store/chill/age. I do this and it works for me; I do reconnect after a few weeks to make sure I haven't lost any pressure due to leaks.
