Maximizes battery life by removing ions and heavy metals that are present in tap water. The separate bed deionizer uses an ion exchange cartridge to filter the water before it enters the battery. Cartridge can be discarded when replacement is necessary. This is determined when output exceeds 50 TDS (water quality light will turn red).
For batteries equipped with Millennium Evo or Pro-Fill systems. (SPW system must have BA-QDV-505 quick coupler.) For inlet water above 300 ppm, it is recommended that a prefilter is used.
