HAC-196 < PRECAUTION > [WITH MONOCHROME DISPLAY] PRECAUTIONS • 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. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant Recovery/Recycling Recharging equipment and Refriger- ant Identifier. • Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo- nents. If lubricant other than that specified is used, compressor failure is likely to occur. • The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol- lowing 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 lubricant from a sealed container. Immediately reseal containers of lubricant. Without proper sealing, lubricant will become moisture saturated and should not be used. - Avoid breathing A/C refrigerant and lubricant 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 lubricant manufacturers. - Do not allow A/C lubricant to come in contact with styrofoam parts or damage may result. CONTAMINATED REFRIGERANT If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are: • Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into the atmosphere. • Explain that recovery of the contaminated refrigerant could damage your service equipment and refrigerant supply. • Suggest the customer return the vehicle to the location of previous service where the contamination may have occurred. • If you choose to perform the repair, recover the refrigerant using only dedicated equipment and contain- ers. Do not recover contaminated refrigerant into your existing service equipment. If your facility does not have dedicated recovery equipment, you may contact a local refrigerant product retailer for available ser- vice. This refrigerant must be disposed of in accordance with all federal and local regulations. In addition, replacement of all refrigerant system components on the vehicle is recommended. • If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN Cus- tomer Affairs for further assistance. Precautions For Refrigerant System Service INFOID:0000000009466442 WORKING WITH HFC-134a (R-134a) CAUTION: • CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. Compressor mal- function is likely to occur if the refrigerants are mixed, refer to “CONTAMINATED REFRIGERANT” below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refriger- ant recovery/recycling recharging equipment and Refrigerant Identifier. • Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. Compressor malfunction is likely to occur if oil other than that specified is used. • The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following handling precautions must be observed: - Cap (seal) the component immediately to minimize the entry of moisture from the atmosphere when removing refrigerant components from a vehicle. - Do not remove the caps (unseal) until just before connecting the components when installing refrig- erant components to a vehicle. Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system. - Use only the specified oil from a sealed container. Reseal containers of oil immediately. Oil becomes moisture saturated and should not be used without proper sealing. - Do not allow oil to come in contact with styrene foam parts. Damage may result.
