PRINCIPLE OF OPERATIONThis closed system electrically heated hot water container can supply hot water toone or more water withdrawing locations within households or institutions.The hot water obtained is suitable for sanitary and consumption purposes, if it isconnected to a drinking water network complying with the limit values laid downin Government Decree No. 201/2001 (X.25.).After reaching the preset temperature, the heating is automatically turned off bythe temperature regulator. The polyurethane heat insulation surrounding the in-ner tank prevents the fast cooling of the water, thus ensuring the availability ofhot water from the container over a long time. Due to the design of the container,hot water is discharged unmixed. The corrosion protection of the inner tank is en-sured by a special enamelling and active anodes. The enamelled design ensureslong service life, even in the case of aggressive (soft) water.4. MOUNTING AND INSTALLATION OF THECONTAINERThe mounting of the hot water container, as well as its connection to thewater and electrical network and commissioning must be performed bya qualified professional according to our instructions and observing thestandards IEC 60364 / MSZ HD 60364.In case of improper connection and installation,you will lose all your guarantee and warrantyrights!
