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 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. PAG lubricant absorbs moisture from the atmosphere at a rapid rate, therefore the following precautions must be
observed:
A. When removing refrigerant components from a vehicle, cap the components immediately to prevent entry of
moisture.
B. When installing refrigerant components to a vehicle, do not remove the cap until just before connecting the
components.
C. Complete the connection of all refrigerant tubes and hoses without delay to prevent the A/C system from taking on
moisture.
