4.2 Display Indicators
The LED display provides important information about the system's status:
- IN TDS: Indicates the Total Dissolved Solids level of the incoming tap water.
- OUT TDS: Indicates the Total Dissolved Solids level of the purified water. A lower OUT TDS value signifies higher purification efficiency.
- Filter Life Indicators (PPC, RO, C): These icons show the remaining lifespan of each filter. When an icon flashes or changes color, it indicates that the corresponding filter needs replacement.
- Flush Button: Initiates a system flush cycle to clean the RO membrane and extend its life.
