found the problem.
16. Because of the instability of ozone, ultraviolet light accelerates the decomposition of ozone and
converts it back to oxygen. After the ozone work is completed, the equipment switches to UV mode to
quickly reduce the ozone concentration in the equipment. The user must never open the cabinet doors
before the device has completed the ozone disinfection operation (before the end of the timer
countdown in the monitor)
17. Users are advised to equip users with ozone concentration detection instruments to regularly detect
whether the leaked ozone value of the equipment exceeds the safe value: long term populated
enclosed spaces, such as houses, apartments, hospitals and offices, ozone must be less than 0.1PPM in
English. If ozone leakage value is found to have exceeded the above standard, the equipment must be
immediately stopped.
To guarantee the disinfect effect of UVC:
1. Whether UV light can effective disinfect depends on the amount of exposure received by the
disinfection object, which depends on the radiation power of the UV light source, the distance of the
disinfection object from the UV light source, and the duration of the exposure to UV light.
2. When killing common microorganisms, the irradiated dose should reach 10,000 μW/cm²; 100,000 μ
W/cm² is the recommended dose to kill bacterial spores. The radiation dose should not be less than
100,000 μW/cm² when the target microorganism for disinfection is unknown.
3. According to the radiation intensity of the UV light source of this product and the general distance of
the UV light source from the irradiated object, it is recommended that:
• In order to achieve the radiation dose of 10,000 μW/cm² to meet the general needs of daily use, the
exposure time should be at least above 1-4 seconds
• In order to achieve the radiation dose of 100,000 μW/cm² to meet the needs of the professional
environment, the exposure time should be at least above 500 seconds
To guarantee the ozone disinfect effect:
1. Ozone can kill bacterial reproductions, viruses, fungi, etc., and can destroy botulinum toxin. In order for
ozone to be effective as a disinfectant, its concentration must be much higher than that that can be
safely tolerated by humans and animals. Ozone has a powerful killing effect on microorganisms in the
air, and at the same time has the odor-removal characteristics, 30minutes of 20mg/m³ (9.35PPM)
concentration of ozone in a sealed environments can achieve disinfection effect. Ozone on the surface
of the items of the microorganism also has a killing effect, requiring 60mg/m³ (28.04PPM), relative
humidity of 70%, and exposure of 60 minutes to 120 minutes, to achieve disinfection effect.
2. If the equipment is stopped in the middle of the operation, the disinfection effect cannot be guaranteed,
a new disinfection session from the start will be necessary.
The reminding of damage about the disinfect objects:
1. The effects of ozone on a variety of substances vary considerably. Glass, stainless steel, butyl rubber,
silicone, polycarbonate, and ABS plastics are better at ozone resistance, but nylon, zinc,
glass-fibre-added plastics, and natural materials such as natural rubber and leather, are less resistant to
ozone.
2. In order to ensure the service life, this product is designed with ozone-resistant materials.
3. In order to examine the accelerated aging effect of ozone on substances, the substance was tested for
