Precaution for Service Equipment


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 HFC134a (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 shutoff 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.
