Setting up your BRITA Flow XXL Water Filter Tank is straightforward, though some initial self-assembly is required. Once assembled, rinse all components thoroughly before first use. Setup: 1. Insert the MAXTRA PRO filter cartridge firmly into the funnel until it clicks into place. 2. Fill the tank with cold tap water. The first two fillings should be discarded or used for watering plants, as this primes the filter. 3. Activate the BRITA Memo digital indicator by pressing and holding the button until all four bars appear. This will start the 4-week countdown for filter replacement. Compatibility: The tank's design is optimized to fit comfortably on most standard fridge shelves or can be conveniently placed on a kitchen countertop. Care: The BRITA Flow XXL tank (excluding the digital indicator) is dishwasher-safe, making cleaning simple. For the digital indicator, gently wipe it with a damp cloth. Regular cleaning of the tank and funnel is recommended to prevent any buildup. Remember to replace the MAXTRA PRO filter cartridge every 4 weeks or after 150 litres of filtered water, whichever comes first, to ensure continuous high-quality filtration.
