When Handling Refrigerant
WARNING: This page is about a different variant/trim than selected.
- 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.
- 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.
- The R-134a container is highly pressurized. Never leave it in a hot place, and check storage temperature is below 52°C (126°F).
- 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.
- Use only recommended lubricant for R-134a systems. If lubricants other than the recommended one used, system failure may occur.
- 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.
- Do not use the same A/C recovery/charging station as conventional belt-driven compressors.
- 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.
- If an accidental discharge in the system occurs, ventilate the work area before resume of service.
