Array LaYOUT <br /> • Find the required structural attachment points. <br /> Mark these using a vertical(N-S).chalk line on the <br /> center of the rafters. <br /> • Spacing may.vary depending upon project specific <br /> structural requirements;Le:high snow and wind <br /> load areas may require lesser bracket spacing,in <br /> the E-W axis vs.the maximum spacing.Max spacing <br /> is 48"for.portrait orientation and 72"for landscape <br /> orientation..Consult project layout diagram for <br /> project specific bracket spacing on the.roof. <br /> • Install-Rock-It Mounts to predetermined mount <br /> spacing. <br /> • The Rock-it Array Skirt sections are.the width of a typical 60.cell <br /> module—.use the.Rock-It Array Skirt.as a guide to'lay out module <br /> placement. <br /> Note:The distance between the rows of mounts is calculated by the module dimension N-S plus T 3/8" <br /> (35mm).Lag screw should be Installed as close to center-of exposed shingle as possible..The minimum. <br /> distance between the lag screw and the edge of shingle is 1/2" <br /> -GreenFaSTe.nTm FLaSHinG InSTaLL <br /> i Locate the rafters and snap horizontal and,vertical lines to mark the installation_ <br /> position for each GreenFasten flashing. <br /> WFA <br /> &_ 2. Drill a pilot hole ON'diameter)for the lag bolt Backfill with sealant.Ecol asten Solar <br /> recommends an.EPDM mastic. <br /> 3 -insert-the flashing so the top part is underthe next row of shingles and pushed far <br /> f' enough-up.slope to prevent water infiltration through vertical joint in shingles.The <br /> leading edge.of flashing must butt against upper row.of nails to preventtuming. <br /> when torqued. <br /> 4 Line up pilot hole with GreenFasten flashing hole. <br /> insert the lag bolt through the EPDM bonded washer,the Rock-it slide,the gasketed. <br /> hole in the flashing and Into the rafter. <br /> Torque:The range Is.between,100-140 torque Inch-pounds depending on the type <br /> of wood and time of-year.The visual.lndicator.for proper torque is when the EPDM <br /> on the underside of the bonded washer-begins to push out the sides as the washer <br /> compresses.If.using an impact wrench to install the fasteners.be careful not to over <br /> torque the fastener.You may.need to stop and use a ratchet to finish the install. <br /> 9be Engineer of Record shall check capacity of rafter to support lag screw loading. <br /> www.ecofastensolarcom info@ecofastensolar.com. 87-77859-3947 4 <br />
