During installation or repair, the vacuum pump is used to remove air and moisture from the system.
The duration can range from a few minutes to several hours, depending on the size and complexity of the AC system.
Once the desired vacuum level is achieved, the vacuum pressure is maintained for a period of time to ensure system integrity.
After the required duration, the vacuum pressure is released and the system is ready for refrigerant charging.
