6 General Terms and Conditions Installation and commissioning should be undertaken by an MCS Certified Solar Installer Company. General terms and conditions of warranty state that all installations must completed by a MCS certified and qualified solar installer company who is currently on the live MCS register of installers. All installer companies should work to the Building Regulations in force at the time of installation.. The manufacturer s warranty will only apply if these installation instructions are followed. The warranty does not cover any damage caused by non- observance of this manual. The correct functionality of the system is only guaranteed if the installation instructions are followed. The end client should be informed at system handover that system should be checked visually once pre year and the heat exchange fluid changed once every four years. Structure The collectors may only be mounted on sufficiently loadbearing roof surfaces and substructures. The structural loadbearing capacity of the roof and the substructure must be assessed on- site, by a suitably experienced professional before mounting the collectors. Particular attention should be paid to the quality of the timber substructure in terms of the stability of the screw joints necessary for installing the collectors. In particular, it is essential to have the entire collector structure verified at the installation site by a qualified engineer in regions with high wind speeds. The assessment should also take into account any special features of the particular site that could lead to increased loads (high wind speeds, snow loads etc). mint renewables Lightning protection / Potential bonding of the building It is not necessary to connect collector arrays to the lightning protection of the building (please observe the specific electrical regulations). For installations on metal substructures at the installation site, authorised lightning protection specialists must be consulted. The metal tubes of the solar circuit must be connected to the main potential equalization bus by means of a conductor (green/yellow) with a cross- section of at least 16mm² CU (H07V- U or R). It is possible to ground the collectors to a ground rod. The grounding line must be laid outside the house. The ground rod must also be connected to the main potential equalization bus by a line with the same crosssection as above. Connections (compression connection fittings) Ladder and scaffolding assembly This document is part of the warranty and should be kept in a safe place and handed over to the end user client on completion of works. Instructions for installation and transport Mint Solar Collectors kits are delivered on pallets. Never store outside in water logged conditions. Always store on a flat surface with glass facing upwards maximum 8 collectors per stack., or vertical with glass facing outwards. The use of a carrying strap is recommended for transporting the collector. The collector must not be lifted at the connections. Avoid impacts and mechanical actions on the solar collector. Mint Solar Collectors should only be used in professionally designed systems with all system components and materials being appropriately rated for use in solar water heating systems and properly installed. Connect the collectors using the certified solar compression connections supplied with your kit. Precautions must be taken to protect the connection pipes against temperature fluctuations caused by heat expansion (expansion bends/flexible piping). In this case, no more than 6 collectors may be connected in series. Larger collector arrays must be assembled with expansion bends or flexible members inserted in the links (IMPORTANT: check the pump design). When tightening the connections, always apply counter pressure with a wrench or another spanner to prevent damage to the manifold connections. Collector inclination / General notes The collector is suitable for installation at an angle of between Steps must be taken to ensure that water and other contaminants such as dust, etc. are prevented from getting into the collector connections and ventilation holes. Warranty Warranty claims can only be made if an appropriate specification of antifreeze is used and maintenance is carried out correctly.

7 Safety Precautions Before commencing mounting work on roofs, it must be ensured in all cases that the non personal fall protection and fall- arrest systems required by DIN (Roof Covering and Roof Sealing Works) and DIN (Scaffolding Works) are in place. See also Builders Protection Ordinance If non- personal fall protection or fall- arrest systems cannot be installed for technical reasons, all personnel must be secured by means of suitable safety harnesses! Only use safety harnesses (safety belts, lanyards and straps, shock absorbers, fall arresters) that were tested and certified by authorized testing bodies. If non- personal fall protection or fall- arrest systems are not provided, working without the use of suitable safety harnesses may lead to falls from heights and therefore cause serious or lethal injuries! Ladders not properly secured against sinking in, sliding or falling over may lead to dangerous falls! Whenever you are near live overhead electric cables where contact is possible, only work if: - it is ensured that they are voltage- free and this is secured for the duration of work. The live parts are secured by the ESB by covering them or cordoning them off. And are deemed safe by ESB transmission supervisor. Or advised safety distances are maintained. Voltage radius: 1m with...voltages up to 1000V 3m with...voltages from 1000V to 11000V 4m with...voltages from 11000V to 22000V 5m with...voltages from 22000V to 38000V > 5m in case of unknown voltages Safety harnesses should be fixed above the users whenever possible. Safety harnesses should only be fastened to sufficiently load bearing structures or fixing points! Never use damaged ladders (e.g., wooden ladders with split runners or rungs, or bent or buckled metal ladders). Never try to repair broken runners, rungs or steps on wooden Ladders! Ensure that ladders are put up safely. Observe the correct leaning angle (68-75 ). Prevent ladders from sliding, falling over or sinking into the ground (e.g. using wider feet, feet suited to the ground or hooking devices). Only lean ladders against secure points. Secure ladders in traffic areas by suitable Cordoning. Contact with live electric overhead cables can be lethal. Wear protective goggles when drilling and handling solar collectors evacuated tube collectors have a danger if damaged of implosion! Wear safety shoes when carrying out installation Work! Wear cut- proof safety gloves when mounting collectors and handling evacuated tube collectors (danger of implosion)! Wear a helmet The manufacturer hereby guarantees to take back products identified with an eco- label and to recycle the materials used. Only the heat transfer medium specified may be used! mint renewables

15 Hydraulic Configuration Key: Flow direction End cap Flow End cap and air vent Return Stop-valve Expansion pipe Corrugated pipe connector Collector connection The following drawings show potential connection solutions. Given the structural conditions, however, the situation can be different in practice. If a collector array comprises more than 6 collectors, the relevant provisions for compensating the heat expansion caused by temperature fluctuations must be included (expansion bends and flexible pipework) or the array will be started up repeatedly in parallel. mint renewables

16 Hydraulic Configurations The diagrams offer a guide to flow methods. Mass flow rate To ensure the performance of the collector, a specific flow rate of 30 l/m²h is to be selected up to a collector panel size of approx.25m².

17 General Information Installing the temperature sensor The solar collector temperature sensor should be installed in the sensor sleeve nearest to the collector array flow. To ensure optimal contact between the temperature sensor and the surrounding environment, the gap between the sensor sleeve and the sensor element should be filled with a suitable conducting compound. All materials used for installing temperature sensors (sensor element, conducting compound, cables, sealing and insulating materials ) must be suitably temperature resistant (up to 250 o c). Operating pressure The maximum operating pressure is 10 bar. Removal of air from the system (bleeding) The system should be properly bled at commissioning to remove as much air as possible from the system. We would recommend that after 2 to 4 weeks of operation the system is bled again. Warning! - When bleeding the system there is a risk of scalding due to steam and hot transfer fluid and appropriate care must be taken. Only operate the bleeding valve if the temperature of the heat transfer fluid is below 60 o c. When bleeding the system the collectors must not be hot! Cover the collectors and, if possible, bleed the system in the morning. Checking heat transfer fluid The heat transfer fluid must be checked at least every four years with regard to its antifreeze content and ph value. Check the antifreeze with an antifreeze tester and replace or refill if necessary. We would recommend a target protection of -25 o c. Check the ph value with a ph indicator rod. If the limit ph value is less than 7.0 then replace the heat transfer fluid. Collector maintenance The solar collectors should be inspected visually, once a year, for any signs of damage, leaks or contamination.
