Not pulling a proper hard vacuum and then "rinsing" or "purging"
with refrigerant as you put it can cost you a minimum $50,000 fine.

You are Not Allowed To Vent Refrigerant to the Atmosphere Anymore,
PERIOD. They make a point to stress this when you get your
refrigerant technician license. It has to be recovered.


Of course you could rinse & purge using propane; a small amount left in
is so similar to refrigerants that it is no problem

Propane is a perfectly good refrigerant, in fact most gas separation
plants use propane as the refrigerant. It runs at different pressures
and temperatures then the "R" stuff but the systems work well.
