For this job I came back to replace the customer's condenser that is the previous one had a restriction in the line dryer and causing a system to over amp which in turn would cost the system to fail. Once I got the old system out I brazed in the new one and rewired it up. I pulled the vacuum down to 250 microns and charge the system to an 8° sub cool and a 7° superheat. System was cooling and producing 18° Delta upon departure.
