Refrigerant: Service and Repair
Discharging And Recovery
DISCHARGING AND RECOVERY
CAUTION:An Air Conditioning (A/C) refrigerant analyzer must be used before the recovery of any vehicle's A/C refrigerant. Failure to do so puts the
shop's bulk refrigerant at risk of contamination. If the vehicle's A/C refrigerant is contaminated, refer the customer to the service facility that carried out
the last A/C service. 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. For all equipment, follow the equipment manufacturer
procedures and instructions.
NOTE:Mazda recommends the use of R-134a refrigerant management equipment that meets the requirements of the SAE J2788 standard.
NOTE:Mazda recommends the use of a R-134a Refrigerant Management Machine to carry out recovery. If a R-134a Refrigerant Management Machine
is not available, refrigerant system recovery may be accomplished using a separate recovery station.
NOTE:Leaks in refrigerant system equipment, hoses or gauges can cause a leak in vacuum that may be misinterpreted as a problem with the vehicle
refrigerant system. It is necessary to leak-test all refrigerant system equipment, hoses and gauges on a weekly basis to verify that no leaks are present.
1. Prior to recovery, you must verify the purity of the refrigerant. See See: Testing and Inspection/Component Tests and General
Diagnostics/Refrigerant Identification Testing.
2. Connect an R-134a Refrigerant Management Machine to the low- and high-pressure gauge port valves following the operating instructions
provided by the equipment manufacturer.
3. Recover the refrigerant from the system following the operating instructions provided by the equipment manufacturer.
4. Once the R134a Refrigerant Management Machine has recovered the refrigerant, switch the power supply OFF.
5. Allow the system to set for approximately 2 minutes and observe the system vacuum reading. If the vacuum is not lost, disconnect the recovery
equipment.
6. If the system does lose vacuum, repeat Steps 3 through 5 until the vacuum level remains stable for 2 minutes.
7. Carry out the required repairs.
