PRECAUTIONS
Precaution 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 electric compressor failure is likely to occur. Checking Of Refrigerant Leaks. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant Recovery/Recycling Recharging equipment and Refrigerant Identifier.
- Use only specified electric compressor oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If electric compressor oil other than that specified is used, electric compressor failure is likely to occur.
- The specified HFC-134a (R-134a) electric compressor 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 the system.
- Only use the specified electric compressor oil from a sealed container. Immediately reseal containers of electric compressor oil. Without proper sealing, electric compressor oil will become moisture saturated and should not be used.
- Avoid breathing A/C refrigerant and electric compressor oil vapor or mist. Exposure may irritate eyes, nose and throat. Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting requirements of SAE J2210 [HFC-134a (R-134a) recycling equipment], or J2209
[HFC-134a (R-134a) recycling equipment], If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and electric compressor oil manufacturers.
- Do not allow electric compressor oil to come in contact with styrofoam parts. Damage may result.
