5. Operating Instructions
The water purifier operates through a five-stage physical filtration process, providing direct drinkable water. No electricity is required, and no wastewater is produced.
Filtration Stages:
- PP Cotton Filter (A): Filters impurities like sediment, rust, and other large particles.
- CTO Filter (B): Absorbs odors, chlorine, and organic chemicals.
- RFC Resin Filter Element (C): Softens limescale and further reduces impurities.
- Ultrafiltration Membrane Filter (UF, D): Filters particles down to 0.01 microns, including bacteria and other fine impurities.
- T33 Post Carbon Filter (E): Provides further adsorption of residual chlorine and odors, improving taste.

Water Pressure Monitoring:
The system includes a pressure gauge to view water pressure in real-time, helping you monitor system performance.

6. Maintenance
Filter Replacement Schedule:
The following times are for reference only and are subject to usage, raw water temperature, water pressure, water quality, and purified water usage. Regular replacement ensures optimal performance.
- PP Cotton Filter (A): 3-6 months
- CTO Filter (B): 6-10 months
- RFC Resin Filter Element (C): 6-10 months
- Ultrafiltration Membrane Filter (UF, D): 12-24 months
- T33 Post Carbon Filter (E): 6-10 months

Rinsing the Ultrafiltration Membrane:
Rinse the ultrafiltration membrane regularly to extend its use time and maintain filtration efficiency. The system includes a sewage outlet for this purpose.

7. Troubleshooting
- Reduced Water Flow: Check if any filters are due for replacement. A clogged filter can significantly reduce water flow. Ensure the ultrafiltration membrane is rinsed regularly.
- Unusual Taste or Odor: This typically indicates that the carbon filters (CTO, RFC, T33) need to be replaced.
- Leaks: Inspect all connections made during installation. Tighten any loose fittings. Ensure O-rings are properly seated.
- TDS Meter Readings: This product is a physical filter and its filtered water retains beneficial minerals. Therefore, a TDS (Total Dissolved Solids) meter is not suitable for testing this product's effectiveness, as it will still show mineral content.
8. User Tips
- Replacement Filters: Replacement filters are essential for continued performance. Please contact the seller or manufacturer for information on purchasing compatible replacement filters.
- Filter Life Indicator: This system does not feature an electronic filter life indicator. Rely on the recommended replacement schedule provided in the maintenance section and observe changes in water flow or taste to determine when filters need changing.
- Initial Flush: After installation or filter replacement, flush the system for several minutes until the water runs clear and any air is purged from the lines.
9. Warranty and Support
For warranty information, technical support, or any product-related inquiries, please contact your original seller or the manufacturer directly. Keep your purchase receipt as proof of purchase.
