Oil Specification |
1. |
The HFC-134a system requires synthetic (POE) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed. |
2. |
Compressor (POE) 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 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 circulates 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.
Total volume of oil in system POE OIL: 130 ± 10 g (4.58 ± 0.35 oz) |
Oil Return Operation
There is close affinity between the oil and 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 run in advance for oil return operation. The procedure is as follows:
1. |
Open all the doors and engine hood. |
2. |
Start the engine and air conditioning switch to "ON" and set the blower motor control knob at its highest position. |
3. |
Stop the engine. |
