- Page 2 There is an associated risk with all water sources and the potential for bio growth, including bacterium that causes Legionnaires disease. DriSteem high-pressure systems, products, and components are designed, with consideration, to reduce the risk of Legionnaires disease and other similar situations. The water treatment and high-pressure system design take into account lower operating temperatures, minimization of stagnant water through mechanical design and flush cycles, and provides an option for UV disinfection of the RO storage water.
- Page 3 Warnings and cautions CAUTION Operate system at above-freezing temperatures. Operating the system at temperatures below freezing can damage the system or cause other property damage. Maintain pumping and water treatment equipment. Inadequately maintained pumping and water treatment equipment can cause the system to fail. Refer to the maintenance section of this IOM for recommended maintenance.
