Pure water

— units designed to work with relatively clean fresh water. In this case, pure water is considered to be water in which the content of mechanical impurities does not exceed 20 g / m3, and the size of individual particles is not more than 5 mm. However, in some models there may be more stringent (or vice versa, softer) requirements for water quality; This point should be clarified according to the official documentation.
