3. Setup and Installation

This filter is designed for push-fit installation into compatible water filtration systems. Always refer to the specific installation instructions provided with your filtration system (e.g., Franke, Omni, Qettle, Carron Phoenix) for detailed steps. The following are general guidelines:

1. Preparation: Turn off the main water supply to your filtration system. Relieve any pressure in the system by opening a tap connected to the filter.
2. Remove Old Filter: Carefully remove the existing filter cartridge from its housing. Be prepared for some residual water to drain.
3. Insert New Filter: Unpack the Doulton UltraCarb SI filter. Ensure the O-rings are properly seated. Insert the new filter into the housing, applying gentle pressure until it clicks securely into place. The push-fit design ensures a tight seal.
4. Flush the Filter: Slowly turn on the main water supply. Open the filtered water tap and allow water to run for 5-10 minutes to flush out any carbon fines and air from the system. This also ensures the filter is fully saturated.
5. Check for Leaks: Inspect all connections for any signs of leaks.

4. Operating Instructions

Once installed and flushed, the Doulton UltraCarb SI filter operates automatically with your compatible water system. Simply open your filtered water tap to dispense purified water. The filter continuously processes water as it flows through the system.

• Initial Use: After installation, it is normal for the water to appear cloudy or contain small black particles for a short period. This is harmless carbon dust and will clear after flushing.
• Flow Rate: The filter may slightly reduce the water flow rate compared to unfiltered water. This is normal and indicates the filter is working effectively.
• Taste and Odor: You should notice an immediate improvement in the taste and odor of your drinking water.

5. Maintenance

Regular maintenance ensures optimal performance and longevity of your Doulton UltraCarb SI filter.

5.1. Filter Replacement

The Doulton UltraCarb SI filter cartridge should be replaced periodically to maintain effective filtration. The recommended replacement interval is typically every 6-12 months, depending on water quality and usage. Refer to your specific system's guidelines for precise timing.

1. Order Replacement: Ensure you have a new Doulton UltraCarb SI filter (Model W9223031) ready before beginning the replacement process.
2. Turn Off Water: Shut off the main water supply to the filtration system and relieve pressure.
3. Remove Old Filter: Twist or pull the old filter out of its housing, depending on your system's design. Dispose of the old filter responsibly.
4. Install New Filter: Follow the "Insert New Filter" and "Flush the Filter" steps from the Setup and Installation section (Section 3).

5.2. Cleaning the Ceramic Filter

One of the advantages of Doulton ceramic filters is their re-cleanable nature. If you notice a significant drop in water flow rate before the recommended replacement period, the ceramic surface may be clogged with sediment. You can clean the filter to restore flow.

1. Remove Filter: Turn off the water supply and remove the filter cartridge as described in the replacement steps.
2. Clean Surface: Using a soft brush or scouring pad (not soap or detergents), gently scrub the outer surface of the ceramic filter under running water. This removes accumulated sediment.
3. Rinse Thoroughly: Rinse the filter thoroughly to remove all loosened particles.
4. Reinstall: Reinstall the cleaned filter into the housing and flush the system as per installation instructions.
