5. Setup

Follow these steps to prepare your RG3 for operation:

1. Unpack and Inspect: Carefully remove the unit from its packaging and inspect for any shipping damage. Ensure all components listed in the "Package Contents" section are present.
2. Position the Machine: Place the RG3 on a stable, level surface in a well-ventilated area.
3. Connect Power: Connect the provided IEC power cord to the machine and then to a grounded 115V AC, 60Hz power outlet.
4. Connect Hoses:
   • Connect the appropriate service hose from the system to be recovered to the "IN" port of the RG3.
   • Connect another service hose from the "OUT" port of the RG3 to your recovery tank. Ensure all connections are tight to prevent leaks.
   • An inline filter should be installed on the inlet side to protect the machine from contaminants.
5. Prepare Recovery Tank: Ensure your recovery tank is empty, evacuated, and within its certification date. Weigh the tank before starting recovery to monitor refrigerant quantity.

6. Operating Instructions

The RG3 is designed for straightforward operation. Always refer to the specific instructions for the refrigerant type you are recovering.

6.1. Liquid Refrigerant Recovery

1. Ensure all hose connections are secure and valves on the recovery tank are open.
2. Turn the "IN" valve on the RG3 to the "LIQUID" position.
3. Turn the "OUT" valve on the RG3 to the "OPEN" position.
4. Turn on the power switch for the RG3. The machine will begin recovering liquid refrigerant.
5. Monitor the gauges. Once liquid recovery slows or stops, proceed to vapor recovery.

6.2. Vapor Refrigerant Recovery

1. After liquid recovery, turn the "IN" valve on the RG3 to the "VAPOR" position.
2. Ensure the "OUT" valve remains in the "OPEN" position.
3. The machine will continue to recover vapor refrigerant. Allow the machine to run until the system pressure reaches a deep vacuum (e.g., -20 to -25 inches of mercury, depending on refrigerant and ambient temperature).
4. Once recovery is complete, turn off the RG3 power switch.
5. Close the valves on the recovery tank and then on the RG3.
6. Carefully disconnect the hoses, being mindful of any residual pressure.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your RG3 unit.

• Filter Replacement: The inline filter on the inlet port should be regularly inspected and replaced as needed to prevent contaminants from entering the machine. A clogged filter can reduce recovery efficiency.
• Cleaning: Keep the exterior of the machine clean. Use a damp cloth to wipe down surfaces. Do not use harsh chemicals or solvents.
• Storage: When not in use, store the RG3 in a clean, dry environment, protected from extreme temperatures and direct sunlight.
• Hose Inspection: Periodically inspect all hoses for cracks, wear, or damage. Replace damaged hoses immediately.
