Assembly:

• Locate the length of the STSR double-threaded screw according to the thickness of the supporting structure.
• Define the spacing of the STSR double-threaded screws according to the snow and wind loads of the installation area of the system and roof pitch.
• Locate the position of STSR double-threaded screws according to the supporting structure and plant layout.
• Drill the support according to the diameter of the screw and the type of support.
• Fasten the STSR double thread screw to the structure by bringing the EPDM rubber into contact with the cover.
• Tighten the MU F flange nut on the gasket to maintain the waterproof seal.
• Attach the SSP or MW connection plate, adjusting its height using the MU F nuts.
