4. Operation This tank is designed for heating and accumulation of heating water in household or industrial applications, however always in closed pressure circuits with forced circulation. Hot water is heated inside the accumulation tank from several possible heat sources like various kinds of heating boilers, renewable energy sources (heat pumps, solar collectors), or also electric heating elements.

6. Installation and Commissioning Installation must meet valid rules and may be done only by qualified staff. Defects caused by improper installation, use or handling are not covered by warranty. After the tank is installed and connected to an existing heating system, it is recommended to clean the entire heating system using a suitable cleaning agent, e.g.
7. Installing Insulation on the Tank Description Thermal insulation is a component of accumulation tanks that prevents heat losses. For these types of accumulation tanks, insulation is supposed to be installed on the spot for easier handling. Insulation made of soft polyurethane foam with a zippered PVC layer is used.

8. Maintenance If the tank is fitted with a heating element, disconnect it from the mains first. Clean the exterior of the tank with a soft cloth and a mild detergent. Never use abrasive cleaners or solvents. Check all connections for leaks. 9.
10.2 Heat exchanger for DHW recirculation It is designed to preheat the circuit of DHW recirculation, enabling to cover the heat loss of the recirculation circuit from the solar system directly. This heat exchanger can be installed in place of the top plug of the accumulation tank. It has a G 1”...
10.3 Watersoft N electromagnetic water treatment device The device for electromagnetic water treatment, Watersoft N, uses no chemicals. It softens water, prevents scale formation and dissolves existing sediments. It is particularly suitable for use with devices with thermally stresses spots like heat exchangers and storage water heaters.
