Lubricant Adjusting Procedure for Compressor Replacement

1. Before connecting ACR4 to vehicle, check ACR4 gauges. No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment

lines.

2. Connect ACR4 to vehicle. Confirm refrigerant purity in supply tank using ACR4 and refrigerant identifier.

If NG, refer to "CONTAMINATED REFRIGERANT".  See: Refrigerant/Service and Repair/Contaminated Refrigerant

3. Confirm refrigerant purity in vehicle A/C system using ACR4 and refrigerant identifier.

If NG, refer to "CONTAMINATED REFRIGERANT".  See: Refrigerant/Service and Repair/Contaminated Refrigerant

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

5. Remove the drain plug of the "old" (removed) compressor. Drain the lubricant into a graduated container and record the amount of drained

lubricant.

6. Remove the drain plug and drain the lubricant from the "new" compressor into a separate, 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. Torque the drain plug.
