2. Installation and Replacement

This section outlines the procedure for replacing your Stokk RS1-RO400-G filter. Ensure you have the correct replacement filter before beginning.

2.1 Safety Precautions

• Always turn off the water supply to the RO system before attempting any maintenance.
• Depressurize the system by opening the filtered water faucet to release any remaining pressure.
• Have a towel or small basin ready to catch any residual water during filter removal.

2.2 Replacement Steps

1. Turn Off Water Supply: Locate the cold water supply valve connected to your Stokk S1 RO system and turn it off.
2. Depressurize System: Open the filtered water faucet (usually on your sink) to relieve pressure from the system. Allow water to drain until it stops.
3. Remove Old Filter: Gently twist the old RS1-RO400-G filter counter-clockwise until it detaches from the system head. Pull it downwards to remove.
4. Prepare New Filter: Remove the new Stokk RS1-RO400-G filter from its packaging. Ensure all protective caps or seals are removed.
5. Install New Filter: Align the new filter with the system head. Push it upwards and twist clockwise until it locks securely into place. You should feel a click or firm stop.
6. Restore Water Supply: Slowly turn on the cold water supply valve to the RO system.
7. Flush the System: Open the filtered water faucet and allow water to run for at least 5-10 minutes to flush out any air bubbles and carbon fines from the new filter. This also helps to 'bleed the lines' as mentioned in user feedback.
8. Check for Leaks: Inspect all connections for any signs of leaks. If leaks are present, turn off the water supply and re-seat the filter.

3. Operating the Filter

The Stokk RS1-RO400-G filter operates continuously as part of your S1 Reverse Osmosis System. Once installed, the system will automatically direct water through the filter for purification.

• Ensure the RO system is connected to a continuous water supply.
• The filter works silently within the system to provide purified water on demand.
• No manual operation of the filter itself is required after installation.

4. Maintenance

Regular maintenance ensures optimal performance and longevity of your Stokk S1 Reverse Osmosis System and its filters.

4.1 Filter Replacement Schedule

The Stokk RS1-RO400-G filter has a recommended lifespan of 12-24 months. This duration can vary based on:

• Your household's filtered water consumption.
• The quality of your incoming tap water.

It is crucial to adhere to the replacement schedule to maintain effective contaminant reduction and water taste.

4.2 General Care

• Periodically check the system and filter connections for any visible leaks.
• Keep the area around the RO system clean and free from obstructions.

5. Troubleshooting

If you encounter issues with your Stokk S1 RO system after filter replacement, refer to the following common troubleshooting tips:

• Reduced Water Flow: Ensure the water supply valve is fully open. Check if the new filter is properly seated and twisted into place. A new filter might initially have slightly lower flow as it saturates.
• Unusual Taste or Odor: If the water has an unusual taste or odor after replacement, ensure the system was flushed adequately (run water for 5-10 minutes). If the issue persists, the filter might be faulty or improperly installed.
• Indicator Light (e.g., Red Light): Some RO systems have indicator lights for filter status or system errors. If a red light persists after filter replacement, it may require a system reset. Consult your Stokk S1 RO system's main manual for specific reset procedures. In some cases, 'bleeding the lines' by flushing the system thoroughly can resolve this.
• Leaks: Immediately turn off the water supply. Re-check the filter installation to ensure it is securely twisted and sealed. Inspect O-rings for damage.
