Setup Instructions
- Unpack the Cartridge: Remove one BWT Magnesium Mineralizer filter cartridge from its protective packaging.
- Prepare the Cartridge: Submerge the new filter cartridge completely in cold tap water for approximately 5 minutes. This helps to remove any air bubbles and activate the filter material.
- Insert into System: Place the prepared cartridge firmly into the designated filter holder of your compatible BWT water filter system (e.g., a BWT water filter jug). Ensure it is seated correctly to prevent water bypass.
- Initial Filtration: Fill the water filter system with tap water. Discard the first two filtered fillings. This flushes out any loose filter particles and prepares the cartridge for regular use.
- Ready for Use: Your BWT Magnesium Mineralizer filter system is now ready to provide filtered, magnesium-enriched water.
Operating Instructions
- Filter Capacity: Each BWT Magnesium Mineralizer filter cartridge has a capacity of approximately 120 liters of water or a maximum usage duration of 4 weeks, whichever comes first.
- Replacement Indicator: Many BWT water filter systems include an electronic or manual indicator to remind you when to replace the cartridge. Follow the instructions for your specific system.
- Optimal Performance: For best results and to maintain water quality, replace the filter cartridge as recommended. Using a cartridge beyond its recommended lifespan may reduce its effectiveness.
- Water Temperature: Use the filtered water for cold beverages or for boiling. Do not filter hot water through the system.
Maintenance
- System Cleaning: Regularly clean your BWT water filter jug or system according to its specific instructions. This typically involves washing with mild detergent and rinsing thoroughly.
- Cartridge Storage: Store unused cartridges in their original, sealed packaging in a cool, dry place away from direct sunlight.
- Disposal: Dispose of used filter cartridges according to local regulations for household waste. The plastic components are generally recyclable.
