Introduction
This manual provides essential information for the installation, operation, and maintenance of your Stokk RS1-RO600-G replacement filter. This filter is specifically designed for compatibility with Stokk S1 Pro and S1 PLUS Reverse Osmosis (RO) water filtration systems.
The Stokk RS1-RO600-G filter features a high-precision 0.0001-micron reverse osmosis membrane, engineered to remove over 99% of more than 1000 contaminants, including Total Dissolved Solids (TDS), PFAS, PFOS, and PFOA. This ensures superior water quality and safety, while also enhancing the taste and clarity of your drinking water.
Setup and Installation
The Stokk RS1-RO600-G filter is designed for effortless installation and replacement. Follow these steps to install your new filter:
- Prepare the System: Ensure your Stokk S1 Pro or S1 PLUS RO system is turned off and the water supply is shut off before beginning the filter replacement process.
- Remove Old Filter: Locate the RO filter cartridge in your system. Gently twist the old filter counter-clockwise to unlock and remove it. Dispose of the old filter responsibly.
- Unpack New Filter: Remove the new Stokk RS1-RO600-G filter from its packaging.
- Insert New Filter: Align the new filter with the designated slot in your RO system. Insert the filter and twist it clockwise until it locks securely into place. You should feel a click or resistance indicating it is properly seated.
- Restore Water Supply: Turn the water supply back on to the RO system.
- Flush the System: Open the filtered water faucet and allow water to run for at least 5-10 minutes to flush out any air and carbon fines from the new filter. This initial flush is crucial for optimal performance and taste.


Operating Instructions
Once the Stokk RS1-RO600-G filter is correctly installed and the system has been flushed, your S1 Pro or S1 PLUS RO system is ready for use. The system will continuously monitor water quality and filter life. Refer to your main RO system's manual for specific operational details, such as dispensing water and understanding indicator lights.
Maintenance
Regular filter replacement is crucial for maintaining the optimal performance and water quality of your Stokk RO system. The Stokk RS1-RO600-G filter has a prolonged lifespan, but it is recommended to replace it every 12-24 months. The exact replacement interval may vary depending on your filtered water consumption and local water quality.
Always follow the installation steps outlined in the 'Setup and Installation' section when replacing the filter.

Troubleshooting
If you encounter issues after replacing your Stokk RS1-RO600-G filter, consider the following:
- Low Water Flow: Ensure the filter is fully seated and locked. Check for any kinks in the water lines. If the issue persists, the filter might be clogged prematurely due to unusually high sediment in the water, or the system may require further flushing.
- Unusual Taste or Odor: Ensure the system was adequately flushed after installation (at least 5-10 minutes). If the taste or odor persists, re-check the filter installation. If the problem continues, contact customer support.
- Leaking: Turn off the water supply immediately. Re-check the filter installation to ensure it is properly seated and twisted into the locked position. Inspect O-rings for damage.
For persistent issues, refer to the comprehensive troubleshooting guide in your main Stokk S1 Pro or S1 PLUS RO system manual.
