I don't know why Mr Havercamp thinks you'd need to open this check valve. Just open a faucet and the pressure will drop to zero.
If you blow the lines out with air, you don't really need the AF. I blew out my Roo 19 for 3 yrs, never added AF, except to the drains and tanks. Blew out my Mini Lite this fall, only added AF to drains and tanks.
I also haven't worried too much about the compressor regulator setting, either. On these little 2-3 gal air compressors, if you've got a faucet open, the pressure drops so fast that it never really gets over 50 psi anywhere in the system. The PEX and fittings should be good for 100 lbs. Now if you were using a 50 gal shop air compressor, it would be a whole 'nother story.
