Align the edges of the <br />modules,and snug them together (Fig. 21, page 22). <br />Trim the rails to the total width of the modules to be; mounted. <br />Place a rail adjacent to the outer mou nting holes. Orient <br />the footing boltslot outward. Place a clip slotadjucent to <br />the mounting holes, following the arrangement you selected <br />earlier. <br />Assemble the clips, mounting bolts, and flange nuts. Torque <br />the fiange nuts to 10 foot-pounds. <br />[3.3.4] Installing the module-rail assembly <br />Bring the module-rail assembly to the installation site. Keep 17- - - <br />rail slots free of debris that might cause bolts to bind in the <br />slots. <br />Consider the weight of a fully assembled panel. Unirac recom- <br />mends safety lines whenever lifting one'to a roof. <br />Align the panel with the previously installed L-feet. Slide 3/8 <br />inch L-foot mounting bolts onto the rail and align them with <br />the L-feet mounting holes. Attach the panel to the L-feet and <br />finger tighten the Range nuts. <br />Rails mav be attached to either of twowmounting holes in the <br />footings (Fig. 25). <br />• Mount in the lower hole for a low, more aethetically <br />pleasing installation. <br />• Or mount in the upper hole to maximize a cooling <br />airffow under the modules. This may enhance perfor- <br />mance in hotter climates. <br />Mo <br />Foonng <br />unling <br />S <br />Flange <br />-nu·1 <br />bolt slot /»0* <br />N%43802 <br />Figure 25. Leg-to-rail attachment <br />Adjust the position of the panel as needed to fit the installa- <br />t:ion area.

Align L-feet <br />with mounting holes previously drilled into the roof. install <br />lag bolts into remaining L-feet as described in "Laying our and <br />m#Alms L.fed." al,Ove. <br />Torque all footing flange nuts to 30 foot-pounds.
