Tools Needed
Before you begin the evacuation process, ensure you have the following tools:
- Inline filter
- Recovery tank
- Gauges
- Hoses
Evacuation Process
- Let the AC run for a few minutes to allow the system to build pressure.
- Gently tap on the AC lines and components to help release any trapped air bubbles.
- If possible, gently rock the car from side to side to help move the air bubbles towards the low side of the system.
- Attach the inline filter to the recovery tank.
- Place the recovery tank in a freezer for a few hours to cool it down.
- Connect the gauges to the AC system, ensuring to open the gauge handwheels.
- Connect one end of the hose to the suction connection of the AC system and the other end to the recovery tank.
- Open the valve on the recovery tank to evacuate the system. You may need to use a wrench to break the connection.
- Allow the evacuation process to run for several minutes until the pressure in the system drops.
- Close the valve on the recovery tank and disconnect the hoses.
Purging the System
Once you have completed the evacuation process, you may need to purge the AC system before recharging it. Purging involves removing any remaining refrigerant and oil from the system. Here is how you can purge the system:
- Use a vacuum pump to create a vacuum in the system and remove any moisture and air.
- Once the system is purged, it can be recharged with the appropriate amount of refrigerant and oil.
