4. Installation (Bulb Replacement)

Important Tip: Before replacing the bulb, please unplug the zapper and let it sit for a few minutes to cool down.
5. Operating Instructions
Once the replacement bulb is securely installed, plug the JY-01C Bug Zapper back into a standard 100-120 Volt, 60 Hertz electrical outlet. The bulb will illuminate, and the bug zapper will begin attracting and eliminating flying insects. The bug zapper is controlled via a push button, as indicated in the product specifications. Refer to your original JY-01C Bug Zapper manual for specific operational details.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your bug zapper and bulb:
- Cleaning the Collection Box: Periodically empty the insect collection box. Ensure the zapper is unplugged before cleaning.
- Cleaning the Grid: Use a small brush (non-metallic) to gently clean any accumulated insect debris from the high-voltage grid. Always ensure the unit is unplugged and discharged before cleaning the grid.
- Bulb Lifespan: UV bulbs typically have an effective lifespan of approximately 3,000 to 5,000 hours, or about 6-8 months of continuous use. While the bulb may still light up, its UV output diminishes over time, reducing its effectiveness in attracting insects. Replace the bulb annually for best results, especially during peak insect seasons.
- Storage: When not in use for extended periods, unplug the bug zapper and store it in a cool, dry place.
7. Troubleshooting
If your bug zapper is not functioning correctly after bulb replacement, consider the following:
- Bulb Not Lighting Up:
- Ensure the bug zapper is securely plugged into a working power outlet.
- Check if the new bulb is fully and correctly seated in its socket.
- Verify that the power switch on the bug zapper is in the "ON" position.
- If the bulb still does not light, the bulb may be faulty. Try another new bulb if available.
- Reduced Effectiveness:
- The UV output of the bulb decreases over time. If the bulb has been in use for over 6-8 months, it may need replacement even if it still lights up.
- Ensure the bug zapper's grid is clean and free of insect debris.
- Check the placement of the bug zapper; it should be in an area where insects are prevalent but not directly competing with other light sources.
