- Ensure the water temperature is between 5-38℃.
- This product is only suitable for municipal tap water.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your water purifier. This includes timely filter replacement and membrane rinsing.
Filter Replacement Schedule:
| Filter Type | Function | Replacement Time (Reference) |
|---|---|---|
| PP Cotton Filter (A) | Filters colloids, impurities, silt, rust, large particles. | 3-6 months |
| Compressed Carbon Filter (B) | Absorbs colors, odors, residual chlorine. | 6-10 months |
| RFC Resin Filter Element (C) | Adsorbs organic matter, softens water, reduces scale. | 6-10 months |
| Ultrafiltration Membrane Filter (D) | Filters suspended solids, colloids, particles > 0.01 microns. | 12-24 months |
| Post Activated Carbon Filter (E) | Further adsorption of residual chlorine and odors. | 6-10 months |
Note: Replacement times are approximate and depend on local water quality and usage volume. It is recommended to buy original replacement accessories from the manufacturer.
Rinsing the Ultrafiltration Membrane:
If the water output becomes smaller, you can open the sewage outlet to rinse the ultrafiltration membrane for 10 minutes. This helps extend its use time.
If the water purifier is not used for a long time, rinse it for 5 minutes before use to ensure normal operation.
When going out for a long time, be sure to close the three-way valve.

- Check Dimensions: Before purchasing, verify the product dimensions (410mm x 350mm for the main unit, 300mm for the faucet) to ensure it fits your intended installation space.
- Filter Availability: Ensure you have access to replacement filters (PP, CTO, RFC, UF, T33) as they need to be changed periodically for optimal water quality.
- Water Pressure: Measure your tap water pressure before installation. If it's above 0.4MPa, install a pressure reducing valve. If it's too low, install a booster pump to ensure proper flow.
- Pre-treatment for Silt: If your raw water has a lot of silt or rust, consider installing a sedimentation filter or pre-treatment system before the water purifier to protect the filters and extend their life.
