3. Installation (Setup)

Proper installation is crucial for the optimal performance of your RO membrane filter. Always refer to your specific RainSoft RO System's manual for detailed instructions on accessing and replacing the membrane housing. The following are general steps:

1. Safety First: Turn off the water supply to your RO system and relieve system pressure by opening the RO faucet.
2. Locate Membrane Housing: Identify the RO membrane housing, typically a larger cylindrical housing compared to pre-filters.
3. Remove Old Membrane: Unscrew the cap of the membrane housing. Carefully pull out the old membrane using pliers if necessary.
4. Clean Housing: Clean the inside of the membrane housing thoroughly with a mild soap solution and rinse well.
5. Prepare New Membrane: Remove the new CFS TFC-RS9-50 membrane from its packaging. Ensure the O-rings are properly seated on the membrane.
6. Insert New Membrane: Insert the new membrane into the housing with the end containing the two O-rings going in first. Push firmly until it is fully seated.
7. Secure Housing: Screw the cap back onto the membrane housing, hand-tightening it securely. Do not overtighten.
8. Restore Water Supply: Slowly turn on the water supply to the RO system. Check for any leaks.
9. Flush System: Allow the system to fill and then flush the new membrane by running the RO faucet for at least 24 hours (or as recommended by your RO system manufacturer) to remove any manufacturing preservatives. Discard this initial water.

Note: Some RainSoft systems may have specific procedures for membrane replacement. Consult your system's original manual for precise steps.

4. Operation

Once installed and flushed, your CFS TFC-RS9-50 Reverse Osmosis Membrane Filter operates automatically as part of your RainSoft RO system. The membrane works by allowing water molecules to pass through its semi-permeable surface while rejecting dissolved solids, contaminants, and impurities, which are then sent to the drain.

Normal Operation:

• The system will produce purified water, which is stored in the RO storage tank.
• When the RO faucet is opened, purified water is dispensed from the storage tank.
• The system will automatically refill the storage tank as water is used.

Important: The performance of the RO membrane is dependent on the quality of the incoming water and the proper functioning of pre-filters (sediment and carbon filters). Ensure these are replaced regularly according to your system's maintenance schedule.

5. Maintenance

The CFS TFC-RS9-50 Reverse Osmosis Membrane Filter is designed for long-lasting performance, typically up to 4 years. However, its lifespan can vary based on the quality of your source water and the frequency of use. Regular maintenance of your entire RO system is essential.

Recommended Maintenance:

• Pre-filter Replacement: Sediment and carbon pre-filters should be replaced every 6-12 months to protect the RO membrane from premature fouling.
• RO Membrane Replacement: Replace the RO membrane every 2-4 years, or sooner if you notice a significant drop in water production, a decline in water quality (e.g., taste, odor), or if your TDS (Total Dissolved Solids) meter indicates high levels.
• System Sanitization: It is recommended to sanitize your RO system annually during filter changes to prevent bacterial growth.

Tip: Keep a record of filter replacement dates to ensure timely maintenance.

6. Troubleshooting

If you experience issues with your RO system after installing the CFS TFC-RS9-50 membrane, consider the following common troubleshooting steps:

If problems persist, contact a qualified technician or CFS customer support.
