1.Check recovery/recycling recharging equipment gauges before connecting recovery/recycling recharging equipment to vehicle. No refrigerant pressure should be displayed. Recover refrigerant from equipment lines if NG.

2.Connect recovery/recycling recharging equipment to vehicle. Confirm refrigerant purity in supply tank using recovery/recycling recharging equipment and refrigerant identifier. Refer to Working with HFC-134a (R-134a) if NG.

3.Confirm refrigerant purity in vehicle A/C system using recovery/recycling recharging equipment and refrigerant identifier. If NG, refer to Working with HFC-134a (R-134a).

4.Discharge refrigerant into the recovery/recycling recharging equipment. Measure lubricant discharged into the recovery/recycling recharging equipment.

5.Drain the lubricant from the old (removed) compressor into a graduated container and recover the amount of lubricant drained.

6.Drain the lubricant from the new compressor into a separate. Then clean container.

7.Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this lubricant to new compressor through the suction port opening.

8.Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant to new compressor through the suction port opening.

9.Add another 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant at this time if the liquid tank also needs to be replaced.Do not add this 5 m (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant when replacing the compressor only.
