Refrigerant Oil: Service Precautions
The HFC-134a systems require a synthetic (PAG) compressor oil.
Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the model of the compressor.
Always use HFC-134a Vane Rotary Type Compressor Oil (AIPDN Part No.2-90188-301-0)
Handling of Oil
*
The oil should be free from moisture, dust, metal powder, etc.
*
Do not mix with other oil.
*
The water content in the oil increases when exposed to the air. After use, seal oil from air immediately, (HFC-134a Vane Rotary Compressor Oil
absorbs moisture very easily.)
*
The compressor oil must be stored in steel containers, not in plastic containers.
