They are fitted with a stainless-steel tube DHW heat exchanger, permitting installation of electric heating elements and connection of other heat sources. For a better thermal layering, the tank volume is separated by a baffle. For proper operation of a tank, it is necessary to have an optimum hydraulic design of the entire heating system, i.e. position of circulation pumps for both heat sources and heating circuits, valves, check valves etc. When more heat sources shall be combined, it is recommended to use a smart controller for both the heat source and heat sink sides of a heating circuit, i.e. also for charging and discharging a thermal store. 1.1 - Models Four models of 560, 760, 925 and 1687 l total volume, with stainless-steel tube DHW heat exchanger. 1.2 - Tank protection The thermal store has no inner surface finish, the outer surface is painted in gray.

Hot water is heated inside the thermal store from several possible heat sources like various kinds of heating boilers, renewable energy sources or also electric heating elements. A stainless-steel tube DHW heat exchanger is heated by heating water inside the thermal store. It connects through 1" threaded fittings. When hot water is drawn from the outlet point, cold water flows into the immersed heat exchanger and heats up by the heating water. The thermal store shall be connected to heat sources through connecting threaded fittings. Individual connection points are assigned according to the circuits to be connected. There is a wide choice of combinations; the following chapter describes just some examples. 5 - Typical Layout Examples with Thermal Store Example I. Heat pump + gas-fired boiler + fireplace + PV possible HW CW recirculation boiler (gas, electric, light oil fired...) PV el. heating elements can be inserted here Example II. Heat pump + el. heating element + fireplace + PV possible HW CW recirculation HW CW electric heating element for DHW electric heating elements for space heating PV el. heating elements can be inserted here 5 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. MR-501/R. Anti-corrosion protective liquid should be also used, e.g. MR-501/F. 6.1 - Connection to heat sources Place the tank on the floor, as close to your heat source as possible. Connect the heating circuits to inlets and outlets respecting the thermal stratification in the tank. Install a drain valve at the lowest point of the tank. Install an air vent valve at the highest point of the system. Insulate all the connection piping 6.2 - Installation of an el. heating element The G 6/4" side tappings are designed to accommodate electric heating rods. They can be connected either directly to the mains (thermostat-equipped rods), or to a heating system controller. The installation may be done by qualified staff only. Warning: Electric heating elements shall be protected by a safety thermostat. 6.3 - Connection to water mains DHW piping shall be done according to valid rules. Installation of a pressure reducing valve on the immersed tank inlet is recommended. For water mains pressure above 6 bar a pressure reducing valve is necessary. To prevent water loss, we recommend installing an expansion vessel at the cold water inlet with a minimum volume of 4% of the total volume of water in the DHW piping, including heat exchangers, circulation pipes, etc. (usually 8 l). Should the water be too hard, install a water softener before the tank. In case the water contains mechanical impurities, install a strainer. Table of limit values for total dissolved solids in hot water. Description pH Total dissolved solids (TDS) Ca Chlorides Mg Max. value 6,5 - 9,5 600mg/l 40mg/l 100mg/l 20mg/l Na 200mg/l Fe 0,2mg/l 6.4 - Commissioning Ground the tank before commissioning. The tank shall be filled up together with the heating system, respecting valid standards and rules. In order to minimize corrosion, special additives for heating systems should be used. The quality of heating water depends on the quality of filling water at commissioning, on the top-up water and on the frequency of topping up. This has a strong influence on the lifetime of heating systems. Poor quality of heating water may cause problems like corrosion or incrustation, esp. on heat transfer surfaces. Quality of DHW shall meet the conditions shown in the Table of limit values for total dissolved solids in hot water on this page. Fill the heating circuits with the appropriate fluids and air-bleed the entire system. Check all connections for leaks and verify the system pressure. Set the heating controller in compliance with the documentation and manufacturer's recommendations. Check regularly the proper function of all control and adjustment elements. 7 - Installing Insulation on the Tank Warning Insulation installation shall be done in two or three persons, depending on its size. The zippered, PVC coated insulation must not be installed at temperatures below 20 °C. If this cannot be avoided, the insulation shall be prewarmed in another room to at least 20 °C. It is impossible to install insulation of lower temperature, there is a risk of damage. Do not use any tools for installation. Keep away from open fire. Installing Insulation 1. Fix the tank following installation instructions. 2. Fit the bottom insulation parts. 3. Wrap the insulation around the tank carefully. Check that the insulation adheres to its body perfectly. This can be reached by rubbing and patting the insulation by hand from its center evenly in both directions until the insulation adheres to the tank's surface completely and no bubbles are left. 6 4. Use the holes for tappings as a rest during the insulation installation. 5. At least one person presses the insulation to the tank, pulling both ends together. The other person closes the insulation lock from the side. 6. Put on the upper insulation and cover 7. Push on the covering plastic rosettes depending on the size of tappings, or put on the flange plug(s) with insulation. 8. Finish the tank installation in compliance with the respective instructions and valid standards and rules. Warranty on insulation Warranty shall become null and void if: the procedure described in the Installation Manual was not respected, the product was used for other purposes than intended. Warranty does not cover: usual wear and tear, damage caused by fire, water, electricity or a natural disaster, defects caused by failure to use the product in compliance with its intended purpose, by improper use and insufficient maintenance, defects caused by mechanical damage to the product, defects caused by tampering or incompetent repair. 7 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 - Disposal Packaging shall be disposed of in compliance with the valid rules. When the product reaches the end of its life, it shall not be disposed of as household waste. It shall be dropped off at a Local Waste Recycling Center. Insulation shall be recycled as plastic and the steel vessel as scrap iron. 10 - Warranty This product is covered by warranty under conditions specified in this Manual and the respective Warranty Certificate.
