## Indications for use
The AmeriWater Ozone Disinfection System is an optional accessory for the AmeriWater Bicarb Solution Mix and Distribution System (SDS) cleared for market under K051031 and the AmeriWater Water Purification System (WPS) for Hemodialysis cleared for market under K991519. It is intended for use in hospitals and dialysis clinics for the disinfection of the AmeriWater SDS and WPS system. The disinfection process is completed during off-hours when the SDS or WPS are not being used for patient treatment. The AmeriWater Ozone Disinfection System provides dissolved aqueous ozone concentrations of at least 0.5 ppm with a contact time of at least 30 minutes for disinfection of the WPS and SDS systems (the entire disinfection process takes approximately 2 hours to complete and longer contact times may be necessary based on microbial loads). The Ozone Disinfection System is designed to produce water with a microbial count of 50 CFU/ml or less.
