Installation and servicing ► Risk of fire from soldering and brazing! Take appropriate safety measures when soldering and brazing as the thermal insulation is flammable. ► Ensure that only a licensed contractor installs or services the DHW tank. ► Use installation material with adequate temperature stability. Forbidden: Connection of the potentiostat for an impressed current anode to the magnesium anode installed in a storage tank is absolutely forbidden! This would destroy the tank!The warranty would be voided.
