When Handling Refrigerant

WARNING: This page is about a different variant/trim than selected.
  1. R-134a liquid refrigerant is highly volatile. A drop on the skin of your hand could result in localized frostbite. When handling the refrigerant, be sure to wear gloves.
  2. It is standard practice to wear goggles or glasses to protect your eyes, and gloves to protect your hands. If the refrigerant splashes into your eyes, wash them with clean water immediately.
  3. The R-134a container is highly pressurized. Never leave it in a hot place, and check storage temperature is below 52°C (126°F).
  4. An electronic leak detector should be used to check the system for refrigerant leakage. Bear in mind that the R-134a, upon coming into contact with flame, produces phosgene, a highly toxic gas.
  5. Use only recommended lubricant for R-134a systems. If lubricants other than the recommended one used, system failure may occur.
  6. PVE or POE lubricant absorbs moisture from the atmosphere at a rapid rate, therefore the following precautions must be observed:
    • When removing refrigerant components from a vehicle, cap the components immediately to prevent entry of moisture.
    • When installing refrigerant components to a vehicle, do not remove the cap until just before connecting the components.
    • Complete the connection of all refrigerant tubes and hoses without delay to prevent the A/C system from taking on moisture.
    • Use the recommended lubricant from a sealed container only.
  7. Do not use the same A/C recovery/charging station as conventional belt-driven compressors.
  8. Since the electric compressor uses high-voltage, you should use PVE or POE oil which have high Volumetric Resistivity.
    WARNING: If the PVE or 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.
  9. If an accidental discharge in the system occurs, ventilate the work area before resume of service.
