I'm also a bit concerned; I just read an hvac forum anecdote stating 'my experience has been that a vacuumed system pulls close to a pound of refrigerant before getting past atmospheric'. If this is accurate, then that would mean I still have/had about a pound in my lines after pumping back to the outdoor unit. With a slow leak, I don't know if that's all gone or not, and without a recovery unit, I still have no way to acquire that. I don't want to risk damaging the Fujitsu compressor by pulling a vacuum..

I think I may call a contractor after a thorough leak test, to recover & fully recharge.
