When evacuating a system that has a solenoid valve what special procedure must be followed?

When evacuating a system with a solenoid valve, it's essential to ensure the valve is in the correct position to allow for proper refrigerant flow during the evacuation process. Additionally, the solenoid valve should be de-energized to prevent any unintended opening or closing, which could lead to refrigerant leaks or system damage. Always follow the manufacturer’s guidelines and safety protocols to ensure a safe and effective evacuation.
