Clean roof surface of dirt, debris, snow and ice. <br />Snap chalk lines for attachment rows. On shingle roofs, snap lines 1/4” belo w upslope edge <br />of shingle coarse. This line will be used to align the upper edge of the mount. <br />NOTE: Space mounts per span charts found in Flashloc Duo D&E Guide. <br />STEP ONE: SECURE <br />ATTACHING TO A RAFTER: Place FLASHLOC DUO over rafter location and align upper edge of <br />mount with horizontal chalk line. Secure mount with the two (2) provided rafter screws. <br />BACKFILL ALL PILOT HOLES WITH SEALANT. <br />ATTACHING TO SHEATHING: Place FLASHLOC DUO over desired location and align upper edge <br />of mount with horizontal chalk line. Secure mount with the two (2) provided rafter screws. <br />Next, secure mount with four (4) deck screws by drilling through the FLASHLOC DUO deck <br />mount hole locations. Unirac recommends using a drill as opposed to an impact gun to prevent <br />over-tightening or stripping roof sheathing. <br />IMPORTANT: SECURELY ATTACH MOUNT BUT DO NOT OVERTIGHTEN SCREWS. <br />STEP TWO: SEAL <br />Insert tip of UNIRAC approved sealant into port and inject until sealant exits vent. <br />Continue array installation, attaching rails to mounts with provided T-bolts. <br />NOTE: When FLASHLOC DUO is installed over gap between shingle tabs or vertical joints, fill gap/joint <br />with sealant between mount and upslope edge of shingle course. <br />CUT SHINGLES AS REQUIRED: DO NOT INSTALL THE FLASHLOC SLIDER ACCROSS THICKNESS <br />VARIATIONS GREATER THAN 1/8" SUCH AS THOSE FOUND IN HIGH DEFINITION SHINGLES. <br />NOTE: When installing included rail attachment hardware, torque T-bolt nut to 30 ft-lbs. <br />NOTE: If an exploratory hole falls outside of the area covered by the sealant, flash hole accordingly. <br />USE ONLY UNIRAC APPROVED SEALANTS.
