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.
6. Let system stand for at least 5 minutes to ensure the system is not leaking. If the gauge does not move, no leaks exist.
7. Follow manufacturer’s instructions to recharge AC System.
Maintenance
1. Always store the Air Operated Vacuum Pump Set in a well-protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust, or any other harmful elements.
2. Keep the Air Operated Vacuum Pump clean for better and safer performance.
