PRECAUTIONS

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 lubricant.

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

Do not 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.
