Upon arrival, found the system extremely low on refrigerant charge. Performed a leak check; no leaks were detected. Pressure tested the system with nitrogen to verify integrity. Pulled a vacuum down to 500 microns to ensure the system was free of moisture and non-condensables. Recharged the system to the factory-specified charge of 3 pounds 5 ounces of R-410A. System is operating properly at this time. No additional issues noted.
