Warning Instructions For Use

1. To avoid energy decay, keep the front glass clean.

2. It is recommended not to have objects blocking the light before the module, which will affect the sterilization effect.

3. Please use the correct input voltage to drive this module, otherwise the module will be damaged.

4. The outlet hole of the module has been filled with glue, which can prevent water leakage, but it is not

recommended that the glue of the outlet hole of the module directly contact the drinking water.

5. Do not connect the positive and negative poles of the module reversely, otherwise the module may be damaged

6. Human safety

Exposure to ultraviolet light can cause damage to human eyes. Don't look at ultraviolet light directly or indirectly.

If exposure to ultraviolet rays is unavoidable, appropriate protective devices such as goggles and clothing should be

used to protect the body. Attach the following warning labels to products / systems
