Important Information
Refrigerant oil attracts moisture. Close any opened containers immediately after use to prevent moisture from entering.
Refrigerant oil, because of its chemical properties, must not be disposed of with engine oils or transmission oils.
Oil Distribution
The oil, which is located in the sump of the A/C compressor before initially switching on the air conditioner system, is distributed through the refrigerant circuit as follows
- A/C compressor approximately 50%
- Condenser approximately 10%
- Suction hose approximately 10%
- Evaporator approximately 20%
- Fluid reservoir approximately 10%
