Setup
- Unpack: Carefully remove the fogger from its packaging and inspect for any shipping damage. Retain packaging for future storage or transport.
- Familiarize: Identify all components: the main motor unit, the 1-gallon solution tank, the adjustable tilt knob, and the droplet size adjustment knob.
- Fill Tank: Unscrew the tank cap and carefully pour the desired chemical solution into the 1-gallon tank. Do not overfill. Ensure the solution is appropriate for ULV fogging and compatible with the fogger. Securely fasten the tank cap.
- Connect Power: Plug the fogger's power cord into a grounded electrical outlet. Ensure the power switch is in the 'OFF' position before plugging in.
Operating Instructions
Follow these steps for effective and safe operation of your Hurricane Ultra II fogger.
- Prepare Area: Ensure the area to be fogged is clear of obstructions and that all necessary safety precautions (e.g., ventilation, removal of sensitive items) are in place.
- Adjust Droplet Size: Locate the droplet size adjustment knob, typically found near the solution intake. Turn the knob to select the desired particle size between 10 and 50 microns. A smaller droplet size is generally used for disinfection and pest control, while larger droplets may be suitable for other applications. Refer to your chemical's instructions for recommended droplet size.
- Adjust Tilt: Use the adjustable tilt knob to set the angle of the fogger head relative to the tank. This allows for precise directional fogging. Loosen, adjust, and then tighten the knob to secure the position.
- Power On: Flip the power switch to the 'ON' position. The motor will start, and fogging will begin.
- Begin Fogging: Hold the fogger by the comfort grip handle and direct the fog towards the target area. Move steadily to ensure even coverage. Avoid prolonged exposure to the fog.
- Monitor Solution Level: Periodically check the solution level in the tank. Refill as needed, ensuring the fogger is powered off before refilling.
- Power Off: Once fogging is complete, turn the power switch to the 'OFF' position.
Applications:
The Hurricane Ultra II is suitable for a variety of applications, including:
- Disinfection of surfaces in commercial, residential, and public spaces.
- Pest control and insect management.
- Odor control and deodorizing.
- Mold remediation.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your fogger.
- Cleaning After Use: After each use, especially when changing chemicals or using corrosive solutions, empty any remaining solution from the tank. Fill the tank with clean water (or a suitable cleaning agent recommended by the chemical manufacturer) and run the fogger for a few minutes to flush the internal lines and nozzles.
- Nozzle Inspection: Periodically inspect the three precision nozzles for any blockages or damage. Clean with a soft brush if necessary.
- Filter Maintenance: The fogger features a removable filter. Regularly inspect and clean this filter to prevent debris from entering the system. Replace if damaged.
- Exterior Cleaning: Wipe down the exterior of the fogger with a damp cloth. Avoid using harsh abrasives or solvents that could damage the plastic components.
- Storage: When not in use, store the fogger in a clean, dry, and temperature-controlled environment. Ensure the tank is empty and clean before storage.
Troubleshooting
If you encounter issues with your Hurricane Ultra II fogger, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Fogger not turning on | No power, faulty switch, damaged cord | Check power outlet and cord. Ensure switch is fully engaged. If cord is damaged, discontinue use and contact support. |
| No fog or reduced output | Empty tank, clogged nozzle/filter, solution viscosity too high, pump issue | Refill tank. Clean nozzles and filter. Ensure solution is appropriate for ULV fogging. If problem persists, contact support. |
| Solution not being drawn up | Clogged intake tube/valve, air leak in system, empty tank | Ensure tank is filled. Check intake tube for kinks or blockages. Flush system with clean water. If a valve is suspected, contact support. |
| Unusual noise during operation | Motor issue, foreign object, loose component | Power off immediately. Inspect for foreign objects. If noise persists, contact support. |
If troubleshooting steps do not resolve the issue, do not attempt further repairs. Contact Curtis Dyna-Fog customer support for assistance.
