Usage Instructions

1. Recover the refrigerant gas from the A/C system. It is recommended to change the filter beforehand to remove moisture.
2. Connect the A/C station and vacuum the system for 8 minutes.
3. Check the vacuum level with a manometer.
4. Turn off the vacuum pump and verify that the vacuum is maintained for at least 5 minutes.
5. If the vacuum cannot be maintained for 5 minutes, the leak is too significant for the product to be effective.
6. If the vacuum test is successful, disconnect the low-pressure (LP) quick coupling from the A/C system. Connect the leak stop product using the quick coupling (B) to the A/C system's low-pressure connection.
7. Holding the product bottle upside down, press the button (A) until the liquid is sucked into the system (approximately 8-10 seconds). Disconnect the leak stop.
8. Recharge the A/C system with the appropriate refrigerant gas and oil, following the vehicle manufacturer's instructions.
9. Start the car and let it run for at least 20 minutes to allow the product to work and seal the leak.
