When water comes out of the drain pipe, water replenishment is complete. close.
If a built-in valve is installed, the water supply valve must be open. Tap water passes through the upper and lower water pipes and begins to replenish solar energy when the water is full. , it will close automatically. When we use water, close the water supply valve, just turn on the water switch or water mixer.
