5. Setup and Installation

The CV-15HS Vacuum Generator is designed for straightforward installation. Follow these steps for proper setup:

1. Prepare Connections: Ensure that all connecting pipes and fittings are clean and free of debris. The vacuum generator has Rp1/4 threads for vacuum, inlet, and outlet connections.
2. Mounting: Securely mount the vacuum generator in the desired location. Its compact size allows for flexible placement. Ensure there is adequate space for connecting hoses and for maintenance access.
3. Connect Air Supply: Connect the compressed air supply line to the inlet port (Rp1/4). Ensure the air supply pressure is within the specified working pressure range of 1-6 BAR.
4. Connect Vacuum Line: Connect the vacuum line to the vacuum port (Rp1/4). This line will lead to the area or system where vacuum is required.
5. Connect Exhaust: The exhaust port (Rp1/4) is where the air is expelled after passing through the Venturi. The integrated silencer is designed to reduce noise from this exhaust. Ensure this port is not obstructed.
6. Leak Check: After all connections are made, perform a leak check to ensure all fittings are tight and there are no air leaks that could compromise vacuum performance.

6. Operating Instructions

Operating the CV-15HS Vacuum Generator is straightforward once installed:

1. Power On Air Supply: Activate the compressed air supply to the vacuum generator. The Venturi effect will immediately begin to create a vacuum at the vacuum port.
2. Monitor Pressure: If your system includes a vacuum gauge, monitor the vacuum pressure to ensure it reaches the desired level (up to -92 BAR).
3. Adjust Air Pressure (if applicable): If your application requires a specific vacuum level, you may adjust the inlet air pressure within the 1-6 BAR range to fine-tune the vacuum output. Higher inlet pressure generally results in a stronger vacuum and higher suction rate.
4. Observe Suction Rate: The maximum suction rate is 63 L/min. This rate will vary depending on the application and the resistance in the vacuum line.
5. Shut Down: To stop vacuum generation, simply turn off the compressed air supply to the unit.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your CV-15HS Vacuum Generator. The unit is designed for low maintenance due to its simple structure.

• Cleanliness: Keep the unit and its connections clean. Dust and debris can affect performance, especially around the exhaust silencer.
• Check Connections: Periodically inspect all threaded connections for tightness. Vibrations or temperature changes can sometimes loosen fittings, leading to air leaks and reduced vacuum efficiency.
• Silencer Inspection: The integrated silencer may accumulate dust or particles over time. If you notice a decrease in air ventilation or an increase in noise, inspect the silencer for blockages and clean it if necessary. The silencer can typically be unscrewed for cleaning.
• Air Quality: Ensure the compressed air supply is clean and dry. Contaminants in the air can lead to internal blockages or wear. Using an air filter and dryer upstream of the vacuum generator is recommended.
• Storage: If the unit is to be stored for an extended period, disconnect it from the air supply and vacuum lines, clean it thoroughly, and store it in a dry, clean environment.
