Upon my arrival, I performed the approved repairs. I recovered all refrigerant from the system for proper disposal, purged with nitrogen while brazing, repaired the leak on the bypass tube for the refrigerant pressure control, installed new filter dryer, pressure tested with nitrogen to 360 psi, installed performance enhancement system, evacuate nitrogen, then put the system into a vacuum. I performed a triple evacuation service breaking with nitrogen and bringing down to a vacuum three times to verify all moisture and contaminants are out of the system. After obtaining the proper vacuum on the system, I installed acid preventatives and recharged to manufacture specifications. I then turn the system on for performance and safety testing to finish out charging the system to the proper sub cool value as well as verifying proper amp draws on the system. I found everything operating within the manufacture specifications at this time.
