Special Tips
1. The filter element replacement cycle is not a warranty period. It is a recommended maintenance cycle under the conditions that raw water meets national drinking water standards and normal household usage.
2. The replacement cycle is an estimated reference. The actual service life varies depending on the region, water quality, water consumption and seasons.
Only timely and correct filter element replacement can ensure safe and clean drinking water.
3.3 Maintenance
Daily maintenance is essential for water purification equipment to prevent malfunctions caused by improper upkeep, avoid risks to drinking water safety, and ensure stable product operation.
1. Do not use highly volatile solvents (e.g., soap, detergent, gasoline, ethyl alcohol) for cleaning and maintenance, as these may cause cracking, scratching, or discoloration of the product surface.
2. Do not clean the purifier by directly spraying water onto it.
3. Regularly check for accumulated water around the product to identify potential water leakage issues.
4. Inspect the product’s outlet tap for signs of leakage.
5. Ensure the concentrated water pipe is securely fixed and free from looseness.
6. Before leaving for an extended period, confirm that the product power supply and water inlet switch (three-way ball valve) are turned off.
7. Do not place the product sideways, horizontally, or upside down.
8. Do not modify the product’s joints or pipes without authorization.
9. Do not store or use the product in environments where the temperature is below 0°C.

7.1 Maintenance Steps
7.2 Filter Element Replacement
1. Filter Element Service Life Indicator Guide
Both PC-C and RO filter element indicators use three colors to show service status:
* Blue light: Normal service life
* Orange light: 20% service life remaining
* Red light: Service life expired (replacement required immediately)
2. RO Filter Element Indicator Guide
The RO filter element indicator also features three color statuses to reflect its service life:
* Blue light on: The filter element is within its normal service life.
* Orange light on: 20% of the service life remains (pre-replacement reminder).
* Red light on: The service life has expired (replacement is required immediately).
3. Take out the upper cover and pull out the filter element handle.
4. Press and hold the end of the filter handle, then pull it toward the unlock direction.
5. Remove the old filter element and install the new filter element into the corresponding filter cartridge.
6. Hold the end of the filter handle and push it in the lock direction until you hear a click (indicating the filter element is securely locked in place).
7. Replace and fasten the top cover of the machine.
8. Reset the filter element service life
Press and hold the Flush/Reset button for 3 seconds to enter the reset mode. Then press the button briefly to select the filter element that was just replaced (the corresponding filter indicator will flash). Press and hold the Flush/Reset button again for 3 seconds to complete the reset — the filter service life will restart counting from zero.
9. Post-replacement flushing operation
Restore the water supply and power to the machine. Press the Flush/Reset button manually; the orange light will flash, which means the filter element is being flushed and cleaned. Once the orange light stops flashing, press the button again, and the machine will switch to normal working state.
