The TANGO3 Water Storage Tank with Ozone Disinfection System is intended to be used for disinfection of the water distribution system of a dialysis facility. The tank of the TANGO3 is also used as the water holding tank of the distribution system. The disinfection process is completely automated. Ozone concentration during disinfection is between 0.2 ppm and 0.3 ppm. Weekly disinfection cycles should be for four periods of 30 minutes with adequate water flushes between them and after the last cycle. In addition to the weekly disinfection cycle, a 45 minute disinfection cycle with at least two rinse cycles may also be performed multiple times weekly for additional reduction of bioburden as determined by user facility monitoring. At the end of disinfection, the distribution loop will have less than 0.1 mg/l. (0.1 ppm) of ozone, in accordance with AAMI/ISO 26722:2009 (4.2.13.5).

Indications for use as stated in the FDA summary.
