I arrived at jobsite to replace Lineset. I cut out the old line side replaced with new. Held pressure at 257 psi for 15 minutes. Pulled vacuum down to 550 µm. Charged with 16 pounds of 410 a. The system is running at 125 psi on suction and 300 psi on discharge. Sub cooling is at 13°F. System is performing at this time.
