Page 5 of 8 STEP 6: Install the lag bolt into the roof (cordless impact wrench rec- ommended) using a ½ socket drive until the lag bolt is seated. DO NOT OVERTIGHTEN. The sealant should flow outward sealing any holes made to locate the rafter. STEP 7: After bolting TileTrac ® to the roof, slide the upper carriage into the correct position under the crown of the tile. STEP 8: Replace the tile by lining up the snap lines, the tile is now ready to be marked and drilled. STEP 9: Using a 3/8 carbide bit and a rotary hammer, drill through the crown of the tile at the intersection of the chalk line and the reference marks. STEP 10: Insert the threaded shaft through the tile into the upper carriage. Bind two 3/8 nuts (provided) using two opposing 9/16 wrenches and tighten to 14 ft. lbs. Before replacing tiles, be sure ALL holes have been properly sealed, including the original hole used to hold the tile in place. Water flows through the valley (lowest point) of the tile, not the crown (highest point), which virtually eliminates any chance of water leakage through the tile attachment. The crown of the tile is the strongest point and will not break when properly drilled. Avoid attaching/drilling in the valley of the tile to prevent water/debris build-up which may lead to leakage. Date Modified: 09/12/07 TileTrac Installation Manual ® A Rotary Hammer Drill re- duces concrete roof tile drill time to approx. 2 seconds. A hammer drill will dramati- cally increase drill time to over one minute. Use of a standard drill will increase time to approx. 10 min- utes. See www.prosolar.com/ tiledrill.htm for demonstration.
