Refrigerant: Service Precautions
Handling Refrigerant
The air conditioning system in this vehicle contains R-134a. This chemical mixture requires special handling procedures to avoid personal injury.
Always wear goggles and wrap a clean cloth around fittings, valves, and connections when performing work that involves opening the refrigerant system.
Always work in well ventilated area and avoid breathing any refrigerant fumes. DO NOT weld or steam clean on or near any air conditioning lines or
components.
If R-134a should come in contact with any part of the body, flush the exposed area with water and immediately seek medical attention.
^
Do not intentionally drop, puncture or incinerate refrigerant containers.
^
Refrigerant will displace oxygen, therefore, be certain to work in well ventilated areas to prevent suffocation.
^
If it is necessary to carry a DOT approved container of Refrigerant-134a in a vehicle, it should not be carried in the passenger compartment.
^
Use only specified lubricant (PAG) for the R-134a A/C system and R-134a components. If lubricants other than those specified are used,
compressor failure is likely to occur.
^
DO NOT store or heat refrigerant containers above 52°C (125°F).
^
DO NOT heat a refrigerant container with an open flame: if container warming is required, place the bottom of the container in a pail of warm
water.
^
DO NOT introduce compressed air to any refrigerant container or refrigerant component. because contamination will occur.
Important
^
All R-134a disposable (colored blue) containers are shipped with a heavy metal screw cap to protect the valve and safety plug of the container
from damage. It is good practice to replace the cap after each use of the container to continue protection.
