7. Risoluzione Dei Problemi

Filter is difficult to install: Ensure the filter is correctly aligned with the head. Apply firm, steady upward pressure while twisting clockwise. If the filter head is not mounted firmly, you may need to support it or temporarily remove it to gain better leverage. Always ensure the water supply is off during this process.
Black particles in water: It is normal for new carbon filters to release a small amount of carbon fines (black particles) during initial use. Flush the filter for 5-10 minutes until the water runs clear. If particles persist, contact customer support.
Leaks after installation: Turn off the water supply immediately. Re-check that the filter is fully seated and twisted securely into the locked position. Ensure the O-rings on the filter are intact and properly positioned.
Flusso d'acqua ridotto: This may indicate that the filter is nearing the end of its service life and is becoming clogged. Replace the filter as per the maintenance schedule.
