4.1. Pre-Installation Checklist

• Ensure you have all components listed in Section 2.
• Verify the installation location has adequate space (dimensions: 465mm L x 150mm W x 390mm H).
• Confirm access to a cold water line and a drain.
• A standard faucet hole (e.g., 1/2 inch or 13mm) is typically required for the included faucet.

4.2. Installation Steps (General Guide)

1. Mount the System: Choose a suitable location under your sink or on a wall. Secure the main unit using the provided mounting hardware.
2. Install the Faucet: Drill a hole (if necessary) in your countertop or sink for the dedicated RO faucet. Secure the faucet and connect the purified water line.
3. Connect Water Supply: Turn off your cold water supply. Install the provided feed water adapter to your cold water line. Connect the inlet tubing from the adapter to the RO system.
4. Connect Drain Line: Install the drain saddle valve onto your sink's drain pipe. Connect the wastewater tubing from the RO system to the drain saddle.
5. Connect Power: Plug the power adapter into the RO system and then into a standard electrical outlet (110V-240V).
6. Flush the System: Turn on the cold water supply. Open the RO faucet and allow water to run for at least 15-30 minutes to flush out any carbon fines and air from the new filters. Check for any leaks during this process.

Note:

• Refer to the detailed user manual included in your package for specific, step-by-step instructions and diagrams.
• Ensure all connections are tight to prevent leaks.

5. Operation

The OSWNKW RO system features an intelligent touch panel for easy control and monitoring.

5.1. Intelligent Touch Panel

The front panel of the system provides real-time information and control:

• TDS Display: Shows the Total Dissolved Solids (TDS) level of the purified water, indicating its purity.
• Function Operation Display: Icons indicate the current operating status (e.g., Purify, Standby, Rinse, Fault).
• Replacement Reminder: Alerts you when it's time to replace filters.
• Reset Button: Used to reset filter life indicators after replacement.
• Flush Button: Initiates a system flush cycle.

6. Maintenance and Filter Replacement

Regular maintenance, primarily filter replacement, is crucial for optimal performance and water quality. The system features automatic filter expiration reminders on its intelligent touch panel.

6.1. Filter Lifespan and Function

The system utilizes a 4-stage filtration process with universal filter cartridges:

• PP Sediment Filter (Stage 1): Blocks rust, sand, and other large particles. Lifespan: 6-12 months.
• PPC Carbon Block Filter (Stage 2): Removes chlorine, pesticides, and odors. Lifespan: 6-12 months.
• NSF 61 RO Membrane (Stage 3): Removes 99.99% of lead, arsenic, bacteria, viruses, and pharmaceuticals. Lifespan: 24-36 months.
• Mineralized Alkaline Filter (Stage 4): Adds calcium and magnesium ions to achieve a balanced alkaline pH. Lifespan: 6-12 months.

6.2. Filter Replacement Procedure

Filter replacement is designed to be quick and tool-free, taking approximately 3 minutes per filter:

1. Turn off Water Supply: Close the cold water supply valve to the RO system.
2. Depressurize System: Open the RO faucet to release any pressure in the system.
3. Remove Old Filter: Twist the old filter cartridge counter-clockwise to unlock and remove it.
4. Install New Filter: Insert the new filter cartridge and twist clockwise to lock it into place. Ensure a snug fit.
5. Reset Filter Life: Press and hold the 'Reset' button on the intelligent touch panel for the corresponding filter stage until the indicator resets.
6. Restore Water Supply: Turn on the cold water supply valve.
7. Flush New Filter: Open the RO faucet and let water run for a few minutes to flush the new filter.

Where to buy replacement filters:

The system uses universal filter cartridges. You can purchase spare filter elements from the official OSWNKW store or other reputable water filter suppliers. Look for PP Sediment, PPC Carbon Block, NSF 61 RO Membrane, and Mineralized Alkaline filters compatible with undercounter RO systems.

7. Troubleshooting

Here are some common issues and their potential solutions:

7.1. No Water Flow or Slow Flow

• Check Water Supply: Ensure the cold water supply valve to the RO system is fully open.
• Check Filter Condition: Clogged filters can restrict flow. Check the filter replacement reminders on the control panel. Replace any expired filters.
• System Pressure: Ensure the incoming water pressure is within the operating range (58-116 PSI).
• Air Lock: After filter changes, an air lock can occur. Flush the system by running water from the RO faucet for several minutes.

7.2. Leaks Detected

• Auto-Shutoff: The system has a built-in leak detection sensor that automatically shuts off water flow if a leak is detected.
• Identify Source: Carefully inspect all connections and filter housings for visible leaks. Tighten any loose fittings.
• O-Rings: Ensure O-rings on filter housings are properly seated and not damaged.

7.3. All Lights Flashing After Filter Change

• This typically indicates that the filter life indicators need to be reset. After replacing each filter, press and hold the corresponding 'Reset' button on the intelligent touch panel until the light stops flashing or resets.

7.4. High TDS Reading After Filtration

• New System/Filter: Allow the system to run for a few hours after initial setup or filter replacement to stabilize.
• RO Membrane: The RO membrane might be exhausted. Check its lifespan (24-36 months) and replace if necessary.
• System Flush: Perform a system flush using the 'Flush' button on the control panel.

7.5. Unusual Taste or Odor

• Carbon Filter: The PPC Carbon Block Filter might be exhausted. Replace it if it's past its recommended lifespan (6-12 months).
• System Flush: Flush the system thoroughly.

8. User Tips

Based on common user inquiries and experiences, here are some helpful tips for using your OSWNKW RO system:

• Filter Availability: The system uses universal filter cartridges, making replacements widely available from the official store or other water filter suppliers. Always check the specific filter types (PP, PPC, RO, MF) and their compatibility.
• Filter Lifespan: While the system provides reminders, keep a personal record of filter installation dates. Lifespans are estimates and can vary based on your local water quality and usage.
• Installation Orientation: The system is primarily designed for vertical installation under a sink or on a wall. Horizontal installation is generally not recommended as it may affect performance or leak detection.
• Power Supply: Ensure you use the correct power supply (110V-240V) and plug type for your region. If you received an incorrect plug connector, contact customer support for assistance.
• Initial Flush: Always perform a thorough flush of the system after initial installation and after every filter change to ensure optimal water quality and remove any residual carbon dust.
• Regular Checks: Periodically check under the sink for any signs of moisture or small leaks, even with the auto-shutoff feature. Early detection can prevent larger issues.
