Setup and Installation
The OSWNKW RO system is designed for easy DIY installation and can be placed under the sink, mounted on a wall, or used on a tabletop. The compact size (465mm x 390mm x 150mm) allows it to fit snugly in most kitchen cabinets. Installation typically takes around 15 minutes.
Installation Steps:
- Unpack and Inspect: Carefully remove all components from the packaging and inspect for any damage. Refer to the 'Package Contents' section to ensure all parts are present.
- Choose Location: Select a suitable location for the main unit, ensuring it is close to a water supply, drain, and power outlet. Consider accessibility for filter changes.
- Install Faucet: Drill a hole (if necessary) in your sink or countertop for the dedicated faucet. Secure the brushed nickel faucet using the provided hardware.
- Connect Water Inlet: Connect the 3/8 inch water inlet pipe from your cold water supply to the system's inlet port. Use the pressure reducing valve if your water pressure exceeds 116 PSI.
- Connect Purified Water Outlet: Connect the 1/4 inch purified water pipe from the system's outlet to the base of the new faucet.
- Connect Wastewater Drain: Connect the 1/4 inch sewage pipe from the system's wastewater outlet to your drain line. A saddle valve or drain clamp is typically used for this connection.
- Power Connection: Plug the power adapter into the system and then into a standard electrical outlet.
- Flush System: Before first use, turn on the water supply and allow the system to flush for at least 15-30 minutes. This removes air from the system and flushes out any carbon fines from new filters.
Operating Instructions
Your OSWNKW RO system features an intelligent touch panel for easy operation and monitoring.
Figure 4: Intelligent Touch Panel
- TDS Display: The real-time LED display shows the Total Dissolved Solids (TDS) level of your purified water, indicating its purity.
- Replacement Reminder: The panel provides automatic reminders when it's time to replace your filter elements, eliminating guesswork.
- Function Operation Display: Icons on the panel indicate the current operating status, such as Purify, Standby, Rinse, and Fault.
- Buttons: Use the touch buttons for functions like 'Reset' (after filter replacement) and 'Flush' (for initial setup or maintenance).
Daily Use:
Simply open your dedicated RO faucet to dispense purified water. The tankless design provides instant flow at 1.58-2.7 L/min, so there's no waiting.
Water Quality Monitoring:
The system continuously monitors water quality. You can observe the TDS readings on the intelligent touch panel. Lower TDS values indicate higher water purity.

Maintenance
Filter Replacement:
The OSWNKW system uses a 4-fold fine filtration process. The intelligent touch panel will remind you when filters need replacement. Filter changes are quick and easy, taking approximately 3 minutes without special tools or a plumber.

Filter Lifespan:
- Stage 1 - PP Sediment Filter: Blocks rust, sand, and other large particles. Recommended replacement: 6-12 months.
- Stage 2 - PPC Carbon Block Filter: Removes chlorine, pesticides, and odors. Recommended replacement: 6-12 months.
- Stage 3 - NSF 61 RO Membrane: Removes 99.99% of lead, arsenic, bacteria, viruses, and pharmaceuticals. Recommended replacement: 24-36 months.
- Stage 4 - Mineralized Filter: Infuses water with calcium and magnesium to achieve a balanced alkaline pH of 7.5 ± 0.5. Recommended replacement: 12-18 months.
Figure 6: Spare Filter Elements
After replacing any filter, press and hold the 'Reset' button on the touch panel to reset the filter life indicator for that specific filter.
Cleaning:
Wipe the exterior of the system with a soft, damp cloth. Do not use abrasive cleaners or harsh chemicals, as these may damage the unit's finish or internal components.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No water flow from faucet | No power; water supply off; clogged filters; air in system. | Check power connection; ensure water supply is on; replace clogged filters; flush system to remove air. |
| High TDS reading on display | RO membrane needs replacement; other filters are exhausted. | Check filter replacement reminders; replace the RO membrane or other indicated filters. |
| System indicates a leak (Fault light) | Loose connection; damaged component. | The system will automatically shut off water. Locate the source of the leak, tighten connections, or replace any damaged parts. |
| Unpleasant taste or odor | Carbon filters are exhausted. | Replace the PPC carbon block filter. |
User Tips
- Monitor TDS Regularly: Keep an eye on the TDS display to ensure your water quality remains optimal. A sudden increase in TDS might indicate a filter nearing the end of its life.
- Keep Spare Filters: Having a set of replacement filters on hand ensures you can quickly change them when the system reminds you, preventing any interruption in your supply of pure water.
- Check Water Pressure: Ensure your home's water pressure is within the recommended range (58-116 PSI) for the best performance and longevity of your RO system.
- Eco-Friendly Operation: The system boasts an efficient 1:2 drainage ratio (clean water to wastewater), significantly reducing water waste compared to traditional RO systems.
