I called and talked with the guy about that a couple of weeks
ago. He said to just put it into the system after you let it fill
to atmospheric pressure with air. He also told me that it doesn't
form acids if there is a bit of humidity in there with the air.
You could also leave the 134 in and just add the Enviro-safe to
bring it up to the needed output since Enviro-safe mixes with 134
or 12 without any problems. Don't try to add enough to get rid of
the bubbles. You will probably need only one more can of the
Enviro-safe to bring the system up to what it needs. The low side
should be under 30lbs.

Last week when I installed the new condenser in The White Whale (R-12
system converted by PO), I charged the system with just one can
of R-134,
and to my pleasant surprise that was enough pressure for the
system to work
and blow cool air. Temps here don't really require AC now, so I'll
probably leave it alone until next summer. I've got a few cans
of one of
the hydrocarbon-based refrigerants, need to come up with a plan for
installing that. Instructions say it should not be installed into a
vacuum, so I need to figure out how this "Enviro Safe" should be
installed.
