Refrigerant Oil: Testing and Inspection

Inspection

Oil Specification

1. The HFC-134a system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never

be mixed.

2. Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the model of compressor.

Handling Of Oil

1. The oil should be free from moisture, dust, metal powder, etc.
2. Do not mix with other oil.
3. The water content in the oil increases when exposed to the air. After use, seal oil from air immediately. (HFC-134a Compressor Oil absorbs

moisture very easily.)

4. The compressor oil must be stored in steel containers, not in plastic containers.

Compressor Oil Check

The oil used to lubricate the compressor is circulating with the refrigerant.
Whenever replacing any component of the system or a large amount of gas leakage occurs, add oil to maintain the original amount of oil.

Oil total volume in system: cc (fl.oz)
Front only : 150 ± 10 (5.07 ± 0.34 fl.oz)
Front & Rear : 210 ± 10 (7.1 ± 0.34 fl.oz)

OIL RETURN OPERATION

There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculates with the refrigerant in the system.
When checking the amount of oil in the system, or replacing any component of the system, the compressor must be run in advance for oil return
operation. The procedure is as follows :

1. Open all the doors and the engine hood.
2. Start the engine and air conditioning switch to "ON" and set the blower motor control knob at its highest position.
3. Run the compressor for more than 20 minutes between 800 and 1,000 rpm in order to operate the system.
4. Stop the engine.
