USE MANIFOLD GAUGES FOR HFC134a AIR CONDITIONING\nAlways use HFC134a dedicated manifold gauges to prevent CFC 12 and CFC 12 compressor oil contaminating the HFC134a system.\n\nQuick Link Connector\nQuick Link Connector\nN04351\n\n2. USE HFC134a GAS LEAK DETECTOR\nSimilarly, always use an HFC134a dedicated leak detector. The CFC12 leak detector is not sufficiently sensitive.\n\nN04144\n\n3. USE VACUUM PUMP ADAPTER\nBy connecting a vacuum pump adapter, the vacuum pump can be used for both HFC134a and CFC12 air conditioning systems.\nThe vacuum pump adaptor has an internal magnetic valve. When evacuation is completed and the vacuum pump switch is turned off, the magnetic valve opens allowing the introduction atmospheric air into the manifold gauges to prevent the back flow of oil from the vacuum pump into the gauge hose.\nCAUTION:\nBe sure to turn off the manifold gauge valve immediately after evacuating the system. Then you may switch off the vacuum pump. If this order is reversed, the line will be temporarily open to atmosphere.\n\nVacuum Pump Adapter\nPlug Cap\nR12 Connection Port\nR134a Connection Port\nVacuum
