1、 Product Introduction
The working principle of the Qianshun brand QS-XZY30 type drinking water ultraviolet sterilizer (hereinafter referred to as the ultraviolet sterilizer) produced by our company is to use ultraviolet rays with wavelengths of 225nm-275nm to kill microorganisms and purify water. When the water flows through the sterilizer and is irradiated with ultraviolet light, the bacteria in the water are killed.

2、 Product Features
1. The ultraviolet sterilizer has fast sterilization speed and good effect, does not change the physical and chemical properties of water, does not increase the odor of water, does not produce by-products, once installed, it is easy to operate and manage.
2. The body of the ultraviolet sterilizer is made of high-quality food grade stainless steel plate, with a long service life, pressure resistance, and no metal ion pollution.
3. The ultraviolet sterilization lamp tube is selected from products identified by the national health and epidemic prevention departments, with a low voltage of 300000 and a main spectral line of 235.7nm. This wavelength of ultraviolet sterilization has a high sterilization rate of over 98% and low energy consumption, with a continuous service life of over 5000 hours.

4. The electrical control part and the box adopt an integrated design, which has a beautiful appearance and saves space.

3、 Scope of action
Installing ultraviolet disinfectors at the outlets of high-level water tanks and storage tanks can effectively solve the problem of excessive bacteria caused by secondary pollution, and is also suitable for water disinfection in the food, beverage, liquor industry, and swimming pools.

4、 Installation and debugging

1UV sterilizers should be installed horizontally (vertical installation is strictly prohibited).

2The cylinder of the ultraviolet sterilizer shall not withstand external pressure.

3. The ultraviolet sterilizer should be installed at the outlet of the water tank or tower. If the water volume is large, the water pressure is high, or the pipeline network is too long, it is better to install it on the water supply main (branch) pipe close to the user.

4. Extending outward from both ends of the ultraviolet sterilizer, there should be a space of ≥ 1 meter and ≥ 0.4 meters respectively for easy replacement of the lamp tube. A 0.6 meter accessible space should be left in front of the control panel of the ultraviolet sterilizer for easy maintenance.

5. Regardless of whether one or more ultraviolet disinfectors are used in parallel, bypass pipelines and shut-off valves should be installed for maintenance purposes.

6. Reasonably choose the installation location and pay attention to the waterproofing and moisture resistance of the electrical control part.

7. Select power sockets, wires, or terminal blocks to connect according to the voltage and power indicated on the nameplate. Quartz glass sleeves and ultraviolet lamps are valuable and fragile items, and should be avoided from being bumped during transportation, installation, and use.
