Envirosafe?

[Dave Yentema]

I broke down today and bought some of that envirosafe stuff, and i've got 
some questions for those who have done it. I picked up 3 6 oz cans, some 
stop leak(to help condition my new seals) a can of oil, a low side gauge and 
some oil level testers.

I've read that you don't need to vacuum the system, and think that absolute 
BS because you can't compress air into a liquid. I don't really have access 
to a vacuum pump, but I've been told you can flush the air out of the system 
by running some of the refrigerant in one side and let it push the air and 
such out of the other side...

Any BTDTs would be awesome, I'd love to know what low side pressures you 
were looking at, etc.

Thanks,
Dave
