How do you pump down freon?

To pump down Freon from a refrigeration or air conditioning system, first ensure the system is turned off and safely isolate it. Connect a refrigerant recovery machine to the service ports, following the manufacturer’s instructions. Open the valves on the recovery machine and allow it to remove the refrigerant until the system is depressurized. Finally, close the valves and disconnect the equipment, ensuring proper handling and disposal of the recovered refrigerant according to local regulations.
