Page 14: Sc (Self Clean) Automatic
SC (Self Clean) Automatic During the production of steam, the concentration of minerals inside the steam generator will increase over time. These minerals settle on the heating elements and heat exchanger as well as the interior steam generator walls. In order to reduce this effect the steam generator will be pumped off and flushed regularly depending on the duration of steam production. -

Page 24: General Information About Water
General information about water The conductivity of the connected water should be above 50μS/cm (micro Siemens). The measured total hardness (TH) is normally higher than the measured amount of calcium or magnesium carbonat (CaCO3, MgCO3). Should the total hardness be smaller than the Carbonat hardness, most likely a water treatment plant is connected. - Page 25 Because of continuous examinations of systems for water treatment we would like to offer you a few information on some different systems. The given statements are only related to Rational units. If you already have made experiences with systems for water treatment, we would be very thankful if you could send us a short fax about your experiences.
