Installed a Mitsubishi single-zone Hyper Heat pump mini split system. After installation, I pressure tested the system with nitrogen at 500 psi and verified there were no leaks. The system was then evacuated to below 300 microns, and a rise test confirmed it maintained vacuum. Once testing was complete, I released the refrigerant charge and placed the system into operation. I tested the indoor unit in heat mode and confirmed proper operation. The system is running properly at this time.
