Preventive Verification Test

1. Identify the charge valve on the low pressure side of the refrigeration or air conditioning system and unscrew the cap.
2. Connect a charging station and make the vacuum of the A/C system for at least 8 minutes.
3. Check the value obtained with a pressure gauge.
4. Switch off the charging station and check that the value obtained is maintained for at least 5 minutes.
5. If it isn’t possible to respect this parameter it means that the leak is too big to be repaired.
