How to Use an A/C Vacuum Pump: A Comprehensive Guide
1. First, connect the vacuum pump hose to the intake port on the A/C compressor and the other end to the manifold gauge set.
2. Turn on the vacuum pump and let it run for approximately 30 minutes.
3. Monitor the gauge readings on the manifold gauge set to ensure the vacuum pressure is stable and within the recommended range.
4. Once the vacuum pressure is stable, shut off the vacuum pump and close the manifold valves.
5. Disconnect the hose from the intake port on the A/C compressor and the manifold gauge set.
6. Your A/C system is now ready for recharging or further repair work.
