5. Setup Guide

Follow these steps to set up your VXSCAN V3 smoke machine for operation.

Fill Test Oil: Open the oil refill port on the top of the device. Using the provided funnel and oil refill bottle, fill 10ml-20ml of Johnson & Johnson baby oil (pink label) or USP Mineral Oil into the detector. Do not overfill.
Prepare Vehicle: Disconnect the intake pipe of the car or the specific pipe system you intend to test. Ensure the engine is off.
Connect Smoke Hose: Connect the smoke hose from the detector to the vehicle's pipe system using the appropriate adapter (e.g., standard cone adapter or intake bladder).
Connect Power: Connect the power cord clamps to the vehicle's DC12V battery. Ensure correct polarity (red to positive, black to negative). The device will power on.

6. Operating Instructions

The VXSCAN V3 offers two operating modes for comprehensive leak detection.

6.1. Air Mode

Air Mode helps you quickly determine if a leak exists in the system by pressurizing it with air. This mode is useful for initial diagnosis.

After connecting the device and powering it on, the power indicator light will be red, indicating normal power supply.
Press the 'Air Mode' button (usually indicated by an air icon). The device will begin to inject air into the pipe.
Observe the pressure gauge. If the pressure drops or does not build up, it indicates a leak. You may also hear a hissing sound if the leak is significant.

Figure 6.1: Using Air Mode for quick leak diagnosis.

6.2. Smoke Mode

Smoke Mode allows you to visually locate the exact point of a leak by filling the system with visible smoke.

After confirming a leak in Air Mode, switch to 'Smoke Mode' by pressing the corresponding button (usually indicated by a smoke icon).
The device will start generating smoke within 10 seconds. The pipe system will be filled with smoke.
Visually inspect the entire system for smoke escaping, which indicates the leak point. Use a flashlight if necessary.
You can adjust the smoke output using the flow meter knob to better control the smoke effect for precise location.

6.3. Interpreting Pressure Gauge Readings

The pressure gauge is crucial for determining the presence and size of a leak.

No Leak: If the pressure gauge index keeps increasing and remains stable, there is no leakage in the system.
Small Leak: If the pressure gauge value drops slowly, it indicates a small leak in the system.
Massive Leak: If the pressure gauge value quickly reaches zero, it indicates a large leak in the system.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your VXSCAN V3 smoke machine.

Oil Refill: If the smoke output becomes weak or stops, it indicates insufficient oil. Refill 10ml-20ml of recommended test oil promptly.
Cleaning: After use, clean the inner side of the air intake hose before placing the universal air inlet bag into the system. Wipe down the exterior of the device with a clean, dry cloth.
Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
Check Gauge Beads: Before each use, ensure the gauge beads can slide freely.

8. Troubleshooting

If you encounter issues with your VXSCAN V3, refer to the following common problems and solutions.

Problem: Device does not produce smoke.
Solution:
1. Ensure the vehicle's ignition is turned off. The device cannot output smoke if connected to a 12V power supply in an office setting; it requires a 12V car battery with an 8A-10A current range.
2. Check if there is enough test oil in the detector. Refill if necessary.
Problem: Weak smoke output.
Solution:
1. Ensure you are using the correct type of oil (Johnson & Johnson baby oil pink label or USP Mineral Oil).
2. Do not exceed the recommended oil refill amount (10ml-20ml). Overfilling can affect smoke production.
3. Check for blockages in the smoke hose or nozzle.
Problem: Pressure gauge does not move or shows no pressure.
Solution:
1. Before use, check if the gauge beads can slide freely. If stuck, gently tap the gauge.
2. Ensure the pressure regulating valve is correctly adjusted.
3. Verify that all connections to the vehicle's system are secure and airtight. A large leak will prevent pressure buildup.
Problem: Device stops working after a short period.
Solution:
The device has a 5-minute auto-stop working cycle for safety. This is normal operation. If it stops prematurely, check for overheating (device has overheat protection) or power supply issues.

If the problem persists after attempting these solutions, please contact VXSCAN customer support for further assistance.
