What do you need to know when using a secondary water UV sterilizer?

What do you need to know when using a secondary water UV sterilizer?
1. The ultraviolet disinfection unit must not be frequently started, especially within a short period of time, to ensure the lifespan of the UV lamp tube.

2. Regular Cleaning of the UV Disinfection Unit: Depending on water quality conditions, the UV lamp tube and quartz glass sleeve need to be cleaned regularly. Use an alcohol-soaked cotton ball or gauze to wipe the lamp tube, removing any dirt from the quartz glass sleeve and ensuring it is thoroughly cleaned, so as to avoid reducing the UV transmittance and compromising the disinfection effectiveness.

3. When replacing the lamp tube, first unplug the power socket of the lamp tube, then carefully remove the old lamp tube. Next, gently insert the cleaned new lamp tube into the sterilizer, secure the sealing ring, and check for any leaks before plugging in the power again. Be careful not to touch the quartz glass of the new lamp tube with your fingers, as any fingerprints could impair its sterilization effectiveness.

4. Preventing UV Radiation: Ultraviolet rays have a strong bactericidal effect, and they can also cause certain harm to the human body. When turning on the disinfection lamp, avoid direct exposure to the human body. If necessary, wear protective eyewear; never look directly at the light source with your eyes, as this could damage the cornea.

It’s also important to note that ultraviolet (UV) water treatment sterilizers, while highly effective at killing bacteria, can also pose certain risks to human health. The part of the body most vulnerable to UV damage is the cornea of the eye. Therefore, under no circumstances should you ever look directly at the UV lamp when it’s lit—doing so could cause serious eye injury. If you absolutely must look at the UV sterilizer’s light, be sure to use ordinary glass (wearing glasses) or a transparent plastic sheet as a protective shield. Under no circumstances should you use quartz glass, as ordinary glass offers virtually no transmission of UV light at all. If you do sustain an injury, don’t panic. For facial burns, the outer skin will peel off after a few days and the condition will heal on its own without treatment. If your eyes are injured, they’ll become red and swollen, start tearing, and feel intensely painful; it’ll take about three to four days for them to recover fully. In any case, if you experience any UV-related injury, it’s strongly recommended that you seek medical attention immediately.

The UV sterilizer boasts high irradiation intensity stability, a sterilization lifespan of up to 9,000 hours, and a high-transmittance quartz glass tube with a light transmittance ≥87%. Its unit price is also moderate compared to similar products. After reaching a sterilization lifespan of 8,000 hours, the irradiation intensity remains stable at 253.7 nm—showing superior stability compared to comparable domestic products. In case of lamp tube breakage, an audible and visual alarm will promptly alert the user. The sterilization reaction chamber features a highly reflective mirror surface design. Compared to similar foreign products, this sterilizer offers an irradiation intensity that is 18% to 27% higher, achieving a sterilization rate as high as 99.99%.
