Precautions for Working with HFC-134a (R-134a)
WARNING:
-
CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants are mixed compressor failure is
likely to occur. Refer "Contaminated Refrigerant". To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use
refrigerant recovery/recycling equipment and refrigerant identifier.
-
Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If oil other than that specified is used,
compressor failure is likely to occur.
-
The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following handling precautions must be
observed:
-
When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize the entry of moisture from
the atmosphere.
-
When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before connecting the components.
Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system.
-
Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without proper sealing, oil will become
moisture saturated and should not be used.
-
Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat. Remove R-134a from the A/C
system using certified service equipment meeting requirements of SAE J2210 (R-134a recycling equipment), or SAE J2209 (R-134a
recovery equipment). If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety
information may be obtained from refrigerant and oil manufacturers.
-
Do not allow refrigerant oil to come in contact with styrofoam parts. Damage may result.
General Refrigerant Precautions
General Refrigerant Precautions
WARNING:
-
Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the refrigerant every time an air
conditioning system is discharged.
-
Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air conditioning system.
-
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 warm
pail of water.
-
Do not intentionally drop, puncture, or incinerate refrigerant containers.
-
Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
-
Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent suffocation.
-
Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air conditioning systems with compressed air
during repair. Some mixtures of air and HFC-134a (R-134a) have been shown to be combustible at elevated pressures. These mixtures, if
ignited, may cause injury or property damage. Additional health and safety information may be obtained from refrigerant
manufacturers.
