1. |
The HFC-134a system requires synthetic compressor oil (PAG) whereas
the R-12 system requires mineral compressor oil. The two oils must never
be mixed.
|
2. |
Compressor oil (PAG) varies according to compressor model. Be
sure to use oil specified for the model of compressor.
|
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.
|
Oil total volume in system
