European standards prescribe six-monthly maintenance for pearl water systems. With BWT's 360-degree operating concept, this can be done in just a few steps as a hygiene inspection.
The BWT IOCLEAN cleaning tablet is simply placed in the designated insert. Follow the instructions for your BWT Perla in the menu item Routine Maintenance & Cleaning. This means that full maintenance of the system is now only necessary every two years.
