Why the other answers are wrong
- A vacuum pump that pushes refrigerant into a pressurized cylinder — The listed method uses a non-pressurized container.
- A vacuum pump with its exhaust open to the room — Exhausting refrigerant to the room is venting, which is illegal.
- A nitrogen bottle used to blow refrigerant out — Pushing refrigerant out with nitrogen is not a listed recovery method.
