3 Safety warnings In the case of mounting on the roof - before the work it is essential to install compliant independent protection against falling or catching device according to DIN on roofing work on the roof and sealing work on roofs and in accordance with DIN for work on scaffolding safety net! Regulation on the protection of workers in construction BGBl 340/ ! It is absolutely necessary to keep other regulations in the country! If there are no safeguards against falling or catching device-independent entities due to the technical reasons, it is necessary to use a safety harness! Use only safety harnesses, which are identified and tested by authorized testing laboratory (safety or webbing, connecting cords / belts, shock absorbers, shortening ropes). If there are no protection devices against falling or catching independent on people, without the use of safety harnesses there is danger of falling from great heights and thus of severe or fatal injuries! Safety harness must be preferably nailed above the user. Fix safety harness only to eventually building components or points that have sufficient capacity! Only prescribed heat transfer medium! Do not use damaged ladders, for example cracked beams with a wooden ladder rungs, bent and broken metal ladders. Do not repair brittle beams, side walls and walls of wooden ladders! Place the strap-on ladders safely. Be careful when attaching the right angle (68-75 ). Strap ladders are secured against slipping, overturning, sliding and running, for example advanced bases, bases ladder adapted substrate hinges. Ladders rest only to the secure anchors. In the field of transport ensure ladders by closures. When using ladders, there is danger of falls caused by slipping, fall or flip over the ladder! Contact with loose electrical lines can be fatal. Near unattached electrical lines, with which contact is possible, work only if state was secured when they are not under voltage and this condition is ensured during the entire period of work, electrically conductive parts are protected by fencing or covering them, and there is no reduction of safety distance. Radius of voltage 1 m V voltage 2 m...voltage from 1000 to V 3 m...voltage from to V 4 m...voltage from to V > 5 m in the case of unknown voltage The manufacturer hereby undertakes to take back products marked with the ecological brand and materials they contain, to deliver for further processing. Only prescribed heat transfer medium can be used! In the case of drilling and handling collectors wear goggles! During installation, wear safety boots! When mounting and handling collectors, wear gloves providing protection against cuts! During installation, wear a helmet! 4

5 Installation instructions General warnings and warnings of carriage The mounting system is only suitable for roofs with tiled roofing. Installation can be performed only by specialized personnel. All work in this guide apply only to such specialized personnel. When installing in principle be used the supplied material. Before installation and operation of solar collectors with a view to inform the applicable local rules and regulations. When transporting the collector is advised to use the conveyor belt. The collector may not be lifted for a connection or threaded screw connections. Avoid shock and mechanical impact on the collector, especially for solar glass, rear wall and pipe connections. Statics roof with tiled roofing Installation may be done only on flat roofs or bearing constructures with sufficient capacity. Before mounting the collectors should definitely check the static load capacity of the roof or bearing constructure, in each case the call should be static, to examine local and regional features. In doing so, it is necessary to pay particular attention to the quality (wood) of bearing constructure - strength bolting consolidating assembly plant collectors. Inspection of the structures collectors at their place of installation according to DIN 1055, part 4 and 5 or under the law of the country is necessary especially in areas with high snow precipitation (note: 1 m3 of snow dust ~ 60 kg / 1 m3 of wet snow ~ 200 kg) or in areas with strong winds. It should be taken of all the specific location of installation of equipment (warm Alpine wind, the effects of flow turbulence wind, etc.) that could result in an increased burden on the device. When selecting the installation site must be ensured in order for not to exceed the maximum loads or forces acting due to wind or snow precipitation. In principle, the collector arrays have to be installed so that if any snow accumulation in the catchment grid (or accumulated due to the specific situation of the installation) can not reach the collector. Collectors may not be installed on the roof edge (it should be observed marginal zone E/10 on flat roofs according to EN 1991, at least 1 m). The upper edge of the collector shall not protrude above the roof. Attention: Installation of a solar collector field represents interference in the (existing) roof. Roofing such as tiles, shingles and slate, especially furnished and habitable attic or roofs with insufficient slope (with respect to their roofing) requires the implementation of construction protections (for example support construction) as a hedge against the ingress of water due to wind pressure and drifting snow. Protection against lightning / settlement potential building In accordance with current standards for protection against lightning ÖVE / ÖNORM EN part 1-4, the collector array may not connect the lightning conductor buildings. It is necessary to keep a safety distance min. 1 m from possible neighboring conductive object. For mounting on a metal support structure is generally necessary to consult with a qualified electrician. In order to realize the potential of settlement building by an authorized electrician must connect metal pipe solar circuit as well as all caps or holders of collectors with the main rail for bonding in accordance with standard ÖVE / ÖNORM E or standards applicable in the country. Connections Collectors must be interconnected, depending on their design screw connections (1 "IG / AG) or by connecting pipe so that the surfaces of joints sealed. It is necessary to ensure the proper imposition of gaskets. If you are not connecting elements as scheduled no flexible hoses, it must be ensured in order to have the connecting pipes take appropriate steps to compensate for thermal expansion due to temperature fluctuations, for example.: Expansion bends and flexible pipes (see link collectors / operational recommendations). For larger collector fields is necessary to insert the expansion bends or flexible joints (Attention: need to check the sizing of the pump). When tightening the connections necessary to follow from the other side (control) or other tick-key, to avoid damage to the absorber. Inclination angle / general information The collector is suitable for slope min. 15 max. 75. Connections collectors and ventilating / air vent openings should be protected from water penetration and dirt and dust ingress, etc. Warranty The warranty arises only use the original means of frost protection from the supplier and properly carried out installation, commissioning and maintenance. A precondition for entitlement to guarantee the installation of qualified personnel, without exception, adherence to instructions in the manual. 6

13 Recommendations for service Rinsing and performance For security reasons, the device must perform when collectors are not exposed to sunlight, where it is necessary to cover collectors. Especially in areas where there is danger of frost, facility has to be filled with a mixture of water containing up to 40% of frost protection. To protect the materials from excessive heat load device is to be filled and placed in service as soon as possible, but not after 4 weeks. If this is not possible before putting into operation is necessary to replace gaskets to prevent leaks. Attention: Pre-mixed composition frost protection is necessary before filling in device mixed with water! Recommended means of frost protection for flat plate collectors: TYFOCOR-L 40% of the means of frost protection (60% / water) - frost point of - 22 C / FREEZING POINT: - 26 C 50% of the means of frost protection (50% / water) - frost point of - 32 C / FREEZING POINT: - 44 C It is possible that filled collectors can no longer be completely removed. For this reason the threat of frost collectors may also be carried out in order to perform pressure and functional testing only a mixture of water and frost protection. Alternatively, you can also do a pressure test using compressed air and spray the leak search jobs. Mounting the sensor The temperature sensor should be mounted in the outlet collector box located next to the sensor housing. In order to ensure optimal contact, the gap between the housing and a sensor with adequate heatconductive paste. When installing the sensor may be used only material with sufficient resistance to high temperatures (250 C) (body sensor, contact paste, wire, sealants, insulation). Operating pressure Max operating pressure is 10 bar. Ventilation Equipment must be vented: - when it is placed in service (after filling), - 4 weeks after commissioning, - if necessary, for example in case of disturbances. Warning: Danger of scalding hot steam or heat transfer fluid! The ventilation valve handle only when the heat transfer fluid temperature < 60. In the discharge device may be hot collectors! Cover Collectors and let out device preferably in the morning. Control of heat transfer fluid Every two years, it is necessary to check the frost protection and heat transfer medium ph. - Frost protection, check with measuring means frost protection and if necessary replace or add the means. Required value of protection is approx C to - 30 C or by weather conditions. - Check the ph with indicator sticks ph (nominal value is approx. PH 7.5): In case of fall below a threshold ph L 7 replace heat transfer medium. Maintenance collector Collector or collector array must be visually inspected every year - if they are not damaged, the seal, pollution, etc. Other recommendations for operation and maintenance can be found in the general instructions for commissioning and maintenance / rules from the supplier. 14

14 Link collector A possible link can be seen in the attached sketch. Based on the structural characteristics of the situation, however, may be different in practice. If the collector field consists of more than 8 collectors in the series, it is necessary to plan appropriate measures to compensate for thermal expansion due to temperature fluctuations (expansion bends or flexible pipe) or a field to be multiple times in parallel run. Output Reverse F Flow rate In order to achieve good performance collector, should be the size of the field around the collector about 25 m² to choose a specific flow rate 30 l / m² h.
