Fixed Tilt Legs Precautions during Stainless Steel Fastener Installation Improper operation may lead to deadlock of Nuts and Bolts. The steps below should be applied to stainless steel nut and bolt assembly to reduce this risk.
  • Page 19 Safe Torques Please refer to safe torques defined in this guide as shown in the figure below. If power tools are required, Clenergy recommends the use of low speed only. High speed and impact drivers increase the risk of bolt galling (deadlock). If deadlock occurs and you need to cut fasteners, please make sure that there is no load on the fastener before you cut it.

    Installation Guide / SolarRoof Tilt Legs Installation Instructions Front & Rear Leg Installation Front Leg Installation According to the installation plan, determine the mounting position and direction of the front legs. Either two screws or single screw (Buildex 14-11 x 70 Hex Head Zips screw) is required depending on the installation spacing requirement. See two screws and single screw options in Figures 1 and 2.
  • Page 22 Installation Guide / SolarRoof Tilt Legs Rear Leg Installation According to the installation plan, after confirming the length L of the Rear Leg, fasten two M8*12 bolts as shown in Figure 4. Recommended torque for M8*12 bolts is 18~20 N·m Figure 4 According to the installation plan, either two screws or single screw (Buildex 14-11 x 70 Hex Head Zips screw) is used to install rear leg.
