What is the purpose of shut off valves on the compressor during installation and when servicing?

Shut-off valves on a compressor are essential for isolating the unit from the system during installation and servicing. They allow technicians to safely perform maintenance or repairs without needing to drain the entire system, thus preventing potential fluid loss and ensuring safety. Additionally, these valves help maintain system pressure and prevent contamination when the compressor is not in use. Overall, they enhance operational efficiency and safety during both installation and servicing.
