Repairing leak by replacing Line Set..... Units got another slow leak someplace but not in the new lineset. Still waiting for the linehide parts to come in to finish the job. Pressurized with one pound Of 410a for a leak test. Switched to a different vac pump and gauge set and that was the problem. Unit is now charged with 6.2 lb of 410a and cooling properly finished linehide today it was not easy customeris happy it's done.
