- Page 6 Installation Guide / SolarRoof Tilt Legs Determine the Installation Area of Roof There are 4 different roof zones for tilt leg installation: Internal Zone, Intermediate Zone, Edge Zone and Corner Zone. Please see diagrams and steps below to define area of each zone. Step 1.
- Page 7 Installation Guide / SolarRoof Tilt Legs Determine Two Screws or One Screw Installations of Tilt Legs There are options of using two screws or one screw for installations of adjustable and fixed tilt legs, depending on the project details, like required support spacing, purlin spacing, rib spacing of roof sheet and so on. Please find both two screws and one screw engineering certificates at the end of installation guides for max support spacing.

The steps below should be applied to stainless steel nut and bolt assembly to reduce this risk.
- Page 18 Installation Guide / SolarRoof Tilt Legs 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.

Page 20: Installation Instruction
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 21 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.
- Page 22 Installation Guide / SolarRoof Tilt Legs Install the remaining Front and Rear Legs in Figure 10. NOTE: WHEN USING TIN INTERFACES FOR INSTALLATION WORKS, SCREWS NOT EXPOSED TO FREQUENT RAIN SHOULD BE WASHED DOWN WITH FRESH WATER AT LEAST EVERY 6 MONTHS TO MEET THE WARRANTY CONDITIONS OF BUILDEX SCREWS.
- Page 23 Figure 15 PV Module Installation 1) Please refer PV-ezRack® Grounding System for PV modules clamps and grounding lugs installations. 2) The installers must ensure panel clamps are installed flush mounted to the panel frame and apply correct torque value of clamp fastener as shown in section "Safe Torques (P17)".
