CONCRETE PURLIN BRACKET VERSION MARCH 2015
GENERAL INSTRUCTIONS Safety: Systems may only be installed and operated by properly trained and technically suitable people (i.e. MCS accredited installers). Installers must at all times adhere to the site s safety procedures and also working at height safety procedures. Information about working safely at heights can be found at www.hse.gove.uk/pubns/indg401.pdf. All systems should not be installed during adverse weather conditions. Regulations: National and local building regulations, standards, environmental regulations, and planning laws must always be adhered. For on-roof systems the load bearing capacity of the roof must be checked by qualified personnel prior to installation. It is recommended for all ground mounted systems that a geological survey is conducted by qualified personnel prior to installation. Design: SUNFIXINGS Ltd require a fully completed checklist in order to issue a copy of the snow and wind loading results. These checklists can be found at www.sunfixings.co.uk/index.php/downloads. SUNFIXINGS Ltd will inform the installer of any specialist requirements, for example the required amount of fixings and minimum/maximum spacing between fixings supplied by SUNFIXINGS Ltd. SUNFIXINGS Ltd must be informed prior to the design process of any module manufacturer s specifications that may affect the installation of the mounting system. The mounting instructions of the module manufacturer should always be adhered to. Prior to Install: It is recommended that all orders are checked upon delivery and any discrepancies or queries are reported to SUNFIXINGS Ltd within 48 hours of accepting the delivery. Asbestos: SUNFIXINGS Ltd does not endorse the drilling into asbestos material. This is solely the responsibility of the installer or other qualified personnel. Torque: The recommended torque settings apply to the following: Middle and Corner Clamp: 12Nm Fixed Connector, Cross Connector, Flexible Connector: 25Nm M10 Screw (A2): 30Nm M12 Screw (A2): 52Nm M12 (zinc plated): 75Nm Flexible Connectors: these must be used after approximately every 18m to allow thermal expansion of the mounting rails 40x40, 40x60, and 40x80 profiles. To install the Flexible Connectors, leave a 20mm gap between the mounting rails and ensure that the middle of the Flexible Connector sits in line with the middle of the gap. Flexible Connectors are not required for the Mounting Rail Direct or Domestic profile; instead break the module array after every 18 th module in a row to leave a 20mm gap before starting the next array of modules. Do not mount modules over the thermal expansion gap. Page 2 of 13
Ground Mounted: It is highly recommended that additional Zinc Galvanising Spray is used on any scratches, cuts, or additional holes drilled into the Park Tegra ground mounted range of frames. For the Park Tegra Ground Anchor system it is recommended that a 2.5 tonne cylinder head Hydraulic auger unit with twin flow application is used to install the Ground Anchors. Ballasted Systems: For ballasted systems, ensure that the correct ballast is applied in the correct position and that wind deflectors/wind bracing has been installed correctly. EPDM: For systems that require the use of EPDM tape, ensure that the surface is cleaned prior to sticking so that it is free of dirt, dust, and grease etc. If it is not possible for the EPDM tape to adhere successfully to the roof, it is possible to fix the EPDM tape to the mounting rail. It is highly recommended that where fixing into roofing cladding with troughs and crowns that the fixings are fixed through the top of the crown. For steel roof cladding, it should be pre-drilled 2 sizes bigger than the diameter of the fixing. Roof Tiles: Roofing tiles may be brushed or grinded to gain a better fit for the Roof Hook system, however it is not recommended to drill into any roofing tiles. To further weather protect the Roof Hook system, use a UV and water resistant sealant around and underneath the Roof Hook. Each Roof Hook should be fixed with a minimum of 2x SUNFIXINGS wood screws. End Caps: The End Caps for the mounting rails are optional and are available upon request at the point of order. During the winter months it may be necessary to keep the End Caps inside a warm environment to maintain elasticity for installation. System Removal: The system can be dismantled and removed by reversing the steps of this document. These mounting instructions are subject to change without prior notice, therefore please contact SUNFIXINGS Ltd to ensure you have the current version. SUNFIXINGS Ltd reserves the right to refuse liability if it is found that these general and mounting instructions have not been adhered to. Maintenance: The system should be properly maintained annually. The use of third party components, including screws, will invalidate the system warranty.
