, r <br /> Array LayOUT <br /> • Find the required structural-attachment points. <br /> Mark these using a vertical(WS)chalk line on.the- <br /> center of the rafters: <br /> • Spacing may vary depending upon project specific <br /> structural requirementsj.'e: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 RocWt.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_bythe module dimension-WS 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 /> GreenFaSTen"m FLasHrnG STaLL <br /> 1 Locate the rafters and snap horizontal and.verticaI lines to mark the installation <br /> a� r position for each GreenFasten flashing. <br /> 2. Drill a pilot hole(1/4"diameter)for the lag bolt Backfill-with sealant.EcoFasten Solar <br /> recommends an.EPDM mastic: <br /> 3 Insert the flashing <br /> so the top part is under.the next row of shingles and pushed far <br /> enough.up.slope to prevent water infiltration through vertical joint in shingles.The <br /> leadin ed e.offlashin must butt against upper row.of.nails to revent.tumin <br /> 9 9 9 9 PP P 9 <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 /> torques.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 /> wwwecofastensolarcom info@ecofastensolarcom 877-859-3947 4 : <br />
