HAC-222 < PRECAUTION > [MANUAL A/C (TYPE 2)] PRECAUTIONS 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. Precaution for Service Equipment INFOID:0000000009478421 MANIFOLD GAUGE SET Be certain that the gauge face indicates R-134a or 134a. Make sure the gauge set has 1/2 ″-16 ACME threaded connections for service hoses. Confirm the set has been used only with refrigerant HFC- 134a (R-134a) along with specified oil. SERVICE HOSES Be certain that the service hoses display the markings described (colored hose with black stripe). All hoses must include positive shut- off devices (either manual or automatic) near the end of the hoses opposite the manifold gauge. SERVICE COUPLERS Never attempt to connect HFC-134a (R-134a) service couplers to a CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will not properly connect to the CFC-12 (R-12) system. However, if an improper connection is attempted, discharging and contamination may occur. SHA533D RHA272D Shut-off valve rotation A/C service valve Clockwise Open Counterclockwise Close RHA273D |
