Caution:a.b.1.2.3.IX. TOOLS FOR REPAIRING REFRIGERATING UNIT HFC-134aConventional repairing devices for CFC-12 can not connect with repairing devices for HFC-134A.Because the shape of fitting for HFC-134A (M10 x P1.5 mm) is different from conventional ones.When the fitting for CFC-12 use is connected with the charge pipe (yellow), and then turn the switch toCFC-12 use, the adaptor can be used for vacuum pumping of CFC-12 refrigeratirng unit.Be sure connect the adaptor with vacuum pump, so it that the vacuum pump can be used for both CFC-12 and HFC-134a.Since the inside of manifold gauge and charge hoses are vacuum state after vacuum pumping, the oil ofvacuum pumping may flow into HFC-134a refrigerant unit.The adaptor prevents the oil from flowinginto the refrigerating unit.Before running the vacuum pump, connect the charge pipe (yellow) with the fitting for HFC-1354a use,and then turn the switch to HFC-134a use.Coupler Plug ( High Pressure Side ) 4mmCoupler SocketCoupler Plug ( Low Pressure Side ) 6.33 / 8mmProcess-Tube-Fitting( 6.35 mm )Process-Tube-Fitting( 4 mm )Charge AdaptorCharge CylinderBlueYellowAdaptorRedManifol GaugeControl ValveCharge HoseVacuum Pump(utk CFC-12/HFC-134a)Fitting for Vacuum PumpFitting forCFC-12Switch( CFC-12 / HFC-134a )Fitting forHFC-134a-7-
