Operating Principles
The Flowtron BF-150 UV bulb emits ultraviolet light, which is highly attractive to a wide range of flying insects, including mosquitoes and moths. Once attracted, insects are drawn to the unit's electrified grid, where they are eliminated. The effectiveness of your insect killer relies on the consistent emission of UV light from the bulb.
Maintenance
To maintain optimal insect attraction, it is recommended to replace your Flowtron UV bulb annually. While the bulb may still illuminate after a year, its UV output, which is crucial for attracting insects, diminishes over time. Regular replacement ensures your insect killer operates at peak efficiency.
Troubleshooting
- Bulb Not Lighting Up:
- Ensure the unit is securely plugged into a working electrical outlet.
- Verify that the bulb is correctly seated in its socket.
- Check if the plastic cover is properly closed and latched.
- If the bulb is old, it may have reached the end of its lifespan and requires replacement.
- Reduced Insect Attraction:
- The UV output of the bulb may have decreased. Consider replacing the bulb if it has been in use for over a year.
- Ensure the unit is placed in an optimal location, away from competing light sources and in an area with insect activity.
