- When the A/C system is being used, the refrigerant oil that was in the A/C compressor before switching on the A/C system for the first time is distributed throughout the entire refrigerant circuit.
- The distribution of the refrigerant oil in the refrigerant circuit varies depending on the last operating conditions of the A/C system before switching it off, the ambient temperatures, etc. A general statement about the refrigerant oil distribution in the refrigerant circuit is therefore not possible. Therefore, observe the information regarding the replacement of refrigerant circuit components. Refer to R134a Refrigerant Circuit Components, Replacing or 1234 yf COMPONENTS, REPLACING
