Recovering Freon without a machine can be done, but it requires safety precautions and the proper techniques. Here are some steps for recovering Freon:
• Ensure that you have all necessary safety equipment such as gloves and eyewear.
• Connect the service hoses to the low-pressure side of the system using an approved recovery cylinder with an appropriate shutoff valve.
• Open both valves on the recovery cylinder to allow liquid refrigerant to flow from one container into another.
• Monitor pressure levels in both containers during transfer until full.
• Close off valves when complete and disconnect hoses safely before disposing of recovered refrigerant properly according to local regulations.
