Foreign matterwill cause bolts to bind as they slide in the slots. 'Jig 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. r 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 908,Splices/Expansion Joints.) Figure 13.Splice bars slide into rhe footing bolt If using more than one splice per rail,contact Unirac concerning slots of SolarMount rail sections. thermal expansion issues. Mounting Rails on Footings:Rails may be 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 Clamping for a higher profile,which will maximize airflow under the modules. This bolt slot 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.

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.
