INSTRUCTIONS
WHEN HANDLING REFRIGERANT
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 that the 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 the lubricant for R-134a systems. If lubricants other than the recommended one
used, system failure may occur.
6. PAG 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 immediately the components to
prevent from the 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. If an accidental discharge in the system occurs, ventilate the work area before resuming service.
