Guys,

Anybody knows where I can find supporting documentation for the R-22 phase out regulations?

I also have 3 questions:
1- Can existing R-22 units still remain in service after the phase out?
2- Can new units be manufactured using existing stocks or new production of R-22? Until when?
3- Is there a cutoff date for the manufacturer of units that use R-22?

Thank you for your answers!
