1A–76 HEATING, VENTILATION AND AIR CONDITIONING (HVAC) Compressor Oil Oil Specification D The HFC-134a system requires a synthetic (PAG) D Compressor (PAG) oil varies according to D Always use HFC-134a Vane Rotary Type Handling of Oil D The oil should be free from moisture, dust, metal D Do not mix with other oil. D The water content in the oil increases when exposed D The compressor oil must be stored in steel Compressor Oil Check The oil used to lubricate the compressor is circulating with Oil Capacity 3 (5.0 fl.oz) Compressor (Service parts) charging amount: 3 (5.0 fl.oz) Checking and Adjusting Oil Quantity 1. Perform oil return operation. Refer to Oil Return Operation in this section. 2. Discharge and recover refrigerant and remove the compressor. 3. Drain the compressor oil and measure the extracted oil with a measuring cylinder. 4. If the amount of oil drained is much less than 90 cm 3 (3.0 fl. oz.), some refrigerant may have leaked out. 5. Check the compressor oil contamination. (Refer to Contamination of Compressor Oil in this section.) 6. Adjust the oil level following the next procedure below. (Charging Amount) (Collected Amount) more than 90 cm 3 (3.0 fl.oz) same as collected less than 90 cm 3 (3.0 fl.oz) 90 cm 3 (3.0 fl.oz) 7. Install the compressor, then evacuate, charge and perform the oil return operation. 8. Check system operation. When it is impossible to preform oil return operation, 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. 3 (3.0 fl. oz.) of oil is extracted from the compressor, supply the same amount of oil to the 5. If the amount of oil extracted is less than 90 cm 3 (3.0 fl. oz.), recheck the compressor oil in the following 6. Supply 90 cm 3 (3.0 fl. 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. oil. 10. Adjust the compressor oil, if necessary.
