What should we pay attention to when using solar water heaters?

1. When cleaning the water pump or replacing the electric heating tube, the power switch must be turned off. Operation with power on is strictly prohibited.
2. Solar water heaters with electric heating must be powered off when bathing, and bathing with electricity is strictly prohibited.
3. Solar water heaters without reliable lightning protection and grounding must not be used during thunderstorms.
4. Use the falling water method to collect water. The electric heating can only be turned on when the water tank is filled with water to prevent the electric heating from dry burning.
