Array LaY OUT i <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;.i:e:high snow and wind <br /> load areas may require lesser bracket spacing in <br /> the EV 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-lt 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 1 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-the-shingle is 1/2" <br /> ereenFasTen FLasHinG insTaLL <br /> 1 Locate the rafters and snap horizontal and vertical lines to mark the Installation- <br /> positionfor each GreenFasten flashing. <br /> 2 Drill a pilot hole OXdiameter)forthe lag bolt.Backfill with sealant.EcoFasten Solar <br /> recommends an.EPDM mastic. <br /> 3 Insert the flashing <br /> sotheto p part is under the next row of shingles and pushed far <br /> ,.d 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 prevent turning <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.Indicator 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 /> 'The Engineer of Record shall check capacity of rafter to support lag screw loading. <br /> www.eccifastensolarcom info@ecofastensolarcom 877-859-3947 4 <br />
