OPERATING INSTRUCTIONS
1. Connect user supplied A/C Manifold to system. (Be sure all manifold valves are closed before connecting)
2. Connect the center hose of the Manifold Gauge Set to the “Vacuum” tee fitting (either R-12 or R-134a) on
the front of the pump. Tightly cap the port not used.
3. Open both valves on the manifold
4. Connect compressed air supply to Vacuum Pump Inlet. The low side gauge should drop below zero and
continue falling. Once gauge reaches its lowest point, let the vacuum pump run for at least 10 and preferably
20 minutes.
5. Closed both manifold valves and disconnect air supply from the vacuum pump.

leaks exist.
