3) Next, purge all the Air out of the Scotty by filling with C02 and releasing the valve.
Do this for several iterations to remove all the air.
If you're a cheap bastard like me, this can waste quite a bit of CO2. An easy check is to pop the scotty/corney cover open while you purge out the air. CO2 is heavier and will stay inside the keg. Use a black product connector to purge gas so it fills from the bottom. It only takes 5-7 seconds of gas at 10ish psi.
To test whether the air is purged, light a butane BBQ starter put it lit into the top area of the keg just inside where the cover would be. If keg/scotty is full of CO2 the flame goes out. Use good sanitation spray star san etc. on all the parts involved.
This technique also works well if you like to flood carboys prior to fermentation to minimize risk of infection.
