Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2
″-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified oils.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must be equipped with
positive shut-off devices (either instruction or automatic) near the end of
the hoses opposite to the manifold gauge.
SERVICE COUPLERS
Do not attempt to connect HFC-134a (R-134a) service couplers to
the CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers
do not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. The hose fitting must be 1/
2
″-16 ACME if the scale controls refrigerant flow electronically.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
