I wondered if you tired just re-torquing the connection with the slow leak?

One installer told me to be careful not to over-torque the flares, but crank them up to the spec,
pressure test and add a little bit more torque if there were bubbles.
He said that almost always works. Otherwise, take the connection apart,
inspect the flare and re-flare if needed.. And repeat making the connection.

I've heard that self pump-down actually recovers almost all of the refrigerant.
If the compressor pulled a vacuum on the line-set, I would be afraid that
a leak in the line, would allow air to get into the stored R410a.
