How to Change Your Billi 994051 Filter (Step-by-Step)

Replacing your filter cartridge takes less than 5 minutes and requires no special tools. Follow these straightforward steps:

1. Access the Under-Bench Unit: Open the cabinet door housing your Billi under-bench system.
2. Isolate Water (Optional): Turn off the water supply valve connected to the tap, or place the system into flush mode.
3. Release Pressure: Dispense a short amount of water from the tap to relieve line pressure.
4. Remove Old Filter: Swing the old filter cartridge forward towards you. Twist it counter-clockwise to unlock, then pull it down gently.
5. Insert New Filter: Remove the protective cap from your new Billi 994051 cartridge. Align the filter head, insert it into the bracket, and turn it clockwise until it locks firmly into place.
6. Flush the System: Swing the filter back into position. Run chilled water for 3–5 minutes (approx. 10 liters) to flush air bubbles and carbon fines from the new filter.
7. Reset Filter Monitor: Hold the filter reset button on your tap display (or under-bench module) until the indicator light resets to green.

When Should You Replace Your Billi 994051 Filter?

Billi recommends replacing your filter cartridge every 6 to 12 months. However, you should replace it sooner if you notice:

• The filter indicator light on your tap turns orange or red.
• A noticeable drop in water flow rate or tap pressure.
• A change in water taste or an unusual chlorine odor.
