3. Installation Instructions
The BRITA A1000 filter cartridge is designed for straightforward installation within the MyPure A1C system, typically located under the sink.
Before You Begin:
- Ensure the main water supply to your tap is turned off.
- Have a towel or small basin ready to catch any residual water.
- Refer to your MyPure A1C system manual for specific housing details.
Steps for Cartridge Installation:
- Locate the Filter Housing: Identify the BRITA MyPure A1C filter housing unit, usually mounted under your kitchen sink.
- Remove Old Cartridge (if applicable): If replacing an old cartridge, twist the old cartridge counter-clockwise to unlock it from the housing. Pull it downwards to remove. Dispose of the old cartridge responsibly.
- Prepare New Cartridge: Remove the new BRITA A1000 cartridge from its packaging. Ensure the protective cap is removed from the top of the cartridge.
- Insert New Cartridge: Align the top of the new A1000 cartridge with the filter housing. Push it upwards into the housing and then twist clockwise until it locks securely into place. You should feel a click or resistance indicating it is properly seated.
- Check for Leaks: Slowly turn the main water supply back on. Check for any leaks around the filter housing and connections. If leaks occur, turn off the water, re-seat the cartridge, and re-check.
- Flush the System: Run filtered water from your tap for approximately 5-10 minutes to flush out any air bubbles and carbon fines from the new cartridge. The water may appear cloudy initially; this is normal and will clear.

4. Operating Instructions
Once installed and flushed, the BRITA A1000 filter cartridge operates automatically with your MyPure A1C system.
- Filtered Water: To dispense filtered water, simply activate the dedicated filtered water tap or lever on your MyPure A1C system.
- Unfiltered Water: Your system may also provide unfiltered water through a separate tap or lever. Refer to your MyPure A1C system manual for specific operation details.
- Flow Rate: The filter provides instantaneous filtration, meaning water is filtered as it passes through the cartridge to your tap.
5. Maintenance
Regular maintenance, primarily cartridge replacement, is essential to ensure optimal performance and water quality.
Cartridge Replacement:
- The BRITA A1000 cartridge typically requires replacement every 6 to 12 months, depending on water hardness and usage.

Cleaning:
- Periodically check the exterior of the filter housing and connections for any dirt or buildup. Wipe clean with a damp cloth.
- Do not use harsh chemicals or abrasive cleaners on any part of the system.
