6. Adjust the oil level following the next procedure below.
7. Install the compressor, then evacuate, charge and perform the oil return operation.
8. Check system operation.
WHEN IT IS IMPOSSIBLE TO PERFORM OIL RETURN OPERATION, THE COMPRESSOR OIL SHOULD BE CHECKED IN THE
FOLLOWING ORDER:
1. Discharge and recover refrigerant and remove the compressor.
2. Drain the compressor oil and measure the extracted oil with a measuring cylinder.
3. Check the oil for contamination.
4. If more than 70 cc (2.47 oz.) of oil is extracted from the compressor, supply the same amount of oil to the compressor to be installed.
5. If the amount of oil extracted is less than 70 cc (2.47 oz.) recheck the compressor oil in the following order.
6. Supply 70 cc (2.47 oz.) of oil to the compressor and install it onto the vehicle.
7. Evacuate and recharge with the proper amount of refrigerant.
8. Perform the oil return operation.
9. Remove the compressor and recheck the amount of oil.
10. Adjust the compressor oil, if necessary.
CHECKING AND ADJUSTING FOR COMPRESSOR REPLACEMENT
150 cc (5.29 oz.) of oil is charged in compressor (service parts). So it is necessary to drain the proper amount of oil from the new compressor.
1. Perform oil return operation.
2. Discharge and recover the refrigerant and remove the compressor.
3. Drain the compressor oil and measure the extracted oil.
4. Check the compressor oil for contamination.
5. Adjust the oil level as required.
6. Evacuate, charge and perform the oil return operation.
7. Check the system operation.
CONTAMINATION OF COMPRESSOR OIL
Unlike engine oil, no cleaning agent is added to the compressor oil. Even if the compressor runs for a long period of time (approximately one season),
the oil never becomes contaminated as long as there is nothing wrong with the compressor or its method of use.
Inspect the extracted oil for any of the following conditions:
1. The capacity of the oil has increased.
2. The oil has changed to red.
3. Foreign substances, metal powder and etc. are present in the oil.
