Air Conditioning (AC) System Flushing
Air Conditioning (A/C) System Flushing
1. Recover the refrigerant.
WARNING:
- Use extreme care and observe all safety precautions related to the use of refrigerants. Due to refrigerant hazards, always wear safety goggles and non-penetrable gloves when working on or flushing air conditioning (A/C) systems. Failure to follow this instruction may result in personal injury.
- When flushing the A/C system. Failure to do so may result in system damage or personal injury.
- The A/C refrigerant analyzer must be used before the recovery of any vehicle's A/C refrigerant. Failure to do so puts shop bulk refrigerant at risk of contamination. If the vehicle A/C refrigerant is contaminated, refer the customer to return to the repair facility that performed the last A/C repair. If the customer wishes to pay the additional cost, use the A/C recovery equipment that is designated for recovering contaminated A/C refrigerant. All contaminated A/C refrigerant must be disposed of as hazardous waste. Failure to follow this instruction may result in personal injury.
- Prior to using the A/C flushing equipment for the first time, follow the operating instructions. Failure to follow this instruction may result in personal injury.
CAUTION: Prior to flushing, remove and discard the desiccant sack. Depending on the equipment used, other A/C components may have to be removed prior to flushing.
2. Remove the desiccant sack.
3. Flush the system.
4. Install new refrigerant lines if blocked with debris.
5. Install a new desiccant sack.
6. Add the required amount of oil to the A/C system depending on the repair procedure.
7. Evacuate and charge the A/C system.
8. Carry out fluorescent dye leak detection test.
9. Check the A/C system for correct operation.
