Installing standoffs: Drill 3/16 inch pilot holes through the underlayment into the center of the rafters at each standoff location. Securely fasten each standoff to the rafters with the two 5/16" lag screws. Ensure that the standoffs face as shown in Figure 11 or 12. Unirac steel and aluminum two-piece standoffs (1-5/8" O.D.) are designed for collared flashings available from Unirac. Install and seal flashings and standoffs using standard building practices or as the company providing roofing warranty directs. SolarMount Unirac Code -Compliant Installation Manual =:=UNI RAC [3.2.4] Installing SolarMount rails Keep rail slots free of roofing grit or other debris. Foreign matter will cause bolts to bind as they slide in the slots. Installing Splices: If your installation uses SolarMount splice bars, attach the rails together (Fig. 13) before mounting the rails to the footings. Use splice bars only with flush installations or those that use low -profile tilt legs. Although structural, the joint is not as strong as the rail itself. A rail should always be supported by more than one footing on both sides of the splice. (Reference installation manual 90B, Splices/Expansion Joints.) If using more than one splice per rail, contact Unirac concerning thermal expansion issues. Mounting Rails on Footings: Rails maybe attached to either of two mounting holes in the L -feet (Fig. 14). Mount in the lower hole for a low profile, more aesthetically pleasing installation. Mount in the upper hole for a higher profile, which will maximize airflow under the modules. This will cool them more and may enhance performance in hotter climates. Slide the '/9 -inch mounting bolts into the footing bolt slots. Loosely attach the rails to the footings with the flange nuts. Ensure that the rails are oriented to the footings as shown in Figure 8, 9, 11, or 12, whichever is appropriate. Aligning the Rail End: Align one pair of rail ends to the edge of the installation area (Fig. 15 or Fig. 16). The opposite pair of rail ends will overhang the side of the installation area. Do not trim them off until the installation is complete. If the rails are perpendicular to the rafters (Fig. 15), either end of the rails can be aligned, but the first module must be installed at the aligned end. If the rails are parallel to the rafters (Fig. 16), the aligned end of the rails must face the lower edge of the roof. Securely tighten all hardware after alignment is complete (20 ft lbs). Mount modules to the rails as soon as possible. Large temperature changes may bow the rails within a few hours if module placement is delayed. Edge of installation area T I Figure 15.

PVA 19 :� U N1 RAC Unirac Code -Compliant Installation Manual SolarMount [3.2.5] Installing the modules Pre -wiring Modules: If modules are the Plug and Play type, no pre -wiring is required, and you can proceed directly to "Installing the First Module" below. If modules have standard J -boxes, each module should be pre -wired with one end of the intermodule cable for ease of installation. For safety reasons, module pre -wiring should not be performed on the roof. Leave covers off J -boxes. They will be installed when the modules are installed on the rails. Installing the First Module: In high-profile installations, the safety bolt and flange nut must be fastened to the module bolt slot at the aligned (lower) end of each rail. It will prevent the lower end clamps and clamping bolts from sliding out of the rail slot during installation. If there is a return cable to the inverter, connect it to the first module. Close the J -box cover. Secure the first module with T -bolts and end clamps at the aligned end of each rail. Allow half an inch between the rail ends and the end clamps (Fig.18). Finger tighten flange nuts, center and align the module as needed, and securely tighten the Flange nuts (10 ft lbs). Installing the Other Modules: Lay the second module face down (glass to glass) on the first module. Connect intermodule cable to the second module and close the J -box cover. Turn the second module face up (Fig. 17). With T -bolts, mid -clamps and flange nuts, secure the adjacent sides of the first and second modules. Align the second module and securely tighten the flange nuts (Fig. 19). For a neat installation, fasten wire management devices to rails with self -drilling screws. Repeat the procedure until all modules are installed. Attach the outside edge of the last module to the rail with end damps. Trim off any excess rail, being careful not to cut into the roof. Allow half an inch between the end clamp and the end of the rail (Fig. 18). .pl t J boxes Figure 17 1/2" minimum yModule frame 1 /4" module bolt and flange nut End clamp Rail Figure 18 Figure 19 -r Module frames 1/4" module bolt and flange nut Rail id clamp High -lipped m;odule ASpacer Low -lipped 1_ (cross section) (cross section) nj a Figure 20.

To significantly reduce its likelihood, (1) apply lubricant to bolts, preferably an anti -seize lubricant, available at auto parts stores, (2) shade hardware prior to installation, and (3) avoid spinning on nuts at high speed. See Installation Supplement 910, Galling and Its Prevention, at www.unirac.com. P., 21 IM . UNI RAC Unirac Code -Compliant Installation Manual SolarMount [3.3.11 Planning the installation area Decide on an arrangement for clips, rails, and L -feet (Fig. 22). Use Arrangement A if the full width of the rails contacts the module. Otherwise use Arrangement B. Caution: Ifyou choose Arrangement B, either (1) use the upper mounting holes of the L feet or (2) be certain that the L feet and clip positions don't conflict. If rails must be parallel to the rafters, it is unlikely that they can be spaced to match rafters. In that case, add structural supports — either sleepers over the roof or mounting blocks beneath it. These additional members must meet code; if in doubt, consult a professional engineer. Never secure the footings to the roof decking alone. Such an arrangement will not meet code and leaves the installation and the roof itself vulnerable to severe damage from wind. Leave enough room to safely move around the array during installation. The width of a rail -module assembly equals the length of one module. Note that L -feet may extend beyond the width of the assembly by as much as 2 inches on each side. The length of the assembly equals the total width of the modules. a,� 22 Distance between lag boll centers x" � 2r pti• Distance between module mounting holes PV module Q 21\ Module boll C::1 t -toot Lag boll Distance between lag bolt centers — Distance between — module mounting holes Figure 22.

They are also used for most ground mount installations. To ensure that the L -feet will be easily accessible during flush installation: • Use the PV module mounting holes nearest the ends of the modules. • Situate the rails so that footing bolt slots face outward. The single slotted square side of the L -foot must always lie against the roof with the double -slotted side perpendicular to the roof. Foot spacing (along the same rail) and rail overhang depend on design wind loads. Install half the L -feet: • If rails are perpendicular to rafters (Fig. 23), install the feet closest to the lower edge of the roof. • If rails are parallel to rafters (Fig. 24), install the feet for one of the rails, but not both. For the L -Feet being installed now, drill pilot holes through the roofing into the center of the rafter at each lag screw hole location. Squirt sealant into the hole and onto the shafts of the lag screws. Seal the underside of the L -feet with a sealant. Securely fasten the L -feet to the building structure with the lag screws. Ensure that the L -feet face as shown in Figure 23 or Figure 24. Hold the rest of the L -feet and fasteners aside until the panels are ready for the installation.

Align the edges of the modules and snug them together (Fig. 21, page 22). Trim the rails to the total width of the modules to be mounted. Place a rail adjacent to the outer mounting holes. Orient the footing bolt slot outward. Place a clip slot adjacent to the mounting holes, following the arrangement you selected earlier. Assemble the clips, mounting bolts, and flange nuts. Torque the flange nuts to 10 foot-pounds. [3.3.4] Installing the module -rail assembly Bring the module -rail assembly to the installation site. Keep rail slots free of debris that might cause bolts to bind in the slots. Consider the weight of a fully assembled panel. Unirac recom- mends safety lines whenever lifting one to a roof. Align the panel with the previously installed L -feet. Slide 3/8 inch L -foot mounting bolts onto the rail and align them with the L -feet mounting holes. Attach the panel to the L -feet and forger tighten the flange nuts. Rails may be attached to either of two mounting holes in the footings (Fig. 25). • Mount in the lower hole for a low, more aethetically pleasing installation. • Or mount in the upper hole to maximize a cooling airflow under the modules. This may enhance perfor- mance in hotter climates. Adjust the position of the panel as needed to fit the installa- tion area. Slide the remaining L -feet bolts onto the other rail, attach L -feet, and finger tighten with flange nuts. Align L -feet with mounting holes previously drilled into the roof. Install lag bolts into remaining L -feet as described in "Laying out and installing L -feet" above. Torque all footing flange nuts to 30 foot-pounds. Verify that all lag bolts are securely fastened.
