Air Conditioning System - Hev: Specifications Kia Optima III

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. Since the electric compressor uses high-voltage, you should use POE oil which have high Volumetric Resistivity. Do not use the same A/C recovery / charging station as conventional belt-driven compressors. WARNING: If the POE oil of the system gets mixed with PAG oil, then dielectric breakdown due to decreased volumetric Resistivity can occur and inoperative A/C compressor may result, A/C compressor may not work. If the POE oil gets mixed with PAG oil, replace the compressor with new one and clean inside the A/C system (condenser, refrigerant line, evaporator and etc.)
