2. Activation: Close the unit securely and activate the sterilization process via the control panel. The user sets the desired duration for the sterilization cycle.
3. Sterilization: The UV-C lamps emit germicidal light, which penetrates and destroys the DNA and RNA of microorganisms. Simultaneously, the ozone generator produces ozone gas that permeates the sterilization chamber, oxidizing and eliminating any remaining pathogens.
4. Completion: Once the cycle is complete, the unit automatically shuts off. The user can then safely open the unit and remove the sterilized items.
Materials
• UV-C Lamps: Made from high-quality quartz glass to ensure optimal transmission of UV-C light.

Step 3: Sterilization
• UV-C lamps (Label E) and the ozone generator (Label F) operate simultaneously, eliminating pathogens: Once the cycle is activated, the high-intensity UV-C lamps emit germicidal light that penetrates and disrupts the DNA and RNA of microorganisms, effectively killing bacteria, viruses, and fungi. Concurrently, the ozone generator produces ozone gas that fills the chamber, oxidizing and destroying any remaining pathogens. This dual-action approach ensures comprehensive sterilization.
Step 4: Completion
• The unit automatically shuts off after the cycle, and the user can safely remove the sterilized items: Upon completion of the sterilization cycle, the unit will automatically power down to signal that the process is complete. Safety mechanisms ensure that no harmful UV-C light or ozone escapes during or after the cycle. The user can then open the unit and safely remove the sterilized items, ready for immediate use or storage.
