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 u on roJect specific, <br /> structural'requirements;1e.high snowand wind <br /> load areas may require lesser bracket spacing,in <br /> the E-W axis vs.the maximum-spacing.Max spacing <br /> is48"for.portrait orientation and72"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-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 ofthe shingle is 1/2" <br /> GreenFasTen` FLasHinG inSTaLL <br /> ON <br /> 1 Locate the rafters and snap horizontal and vertical lines to mark the installation <br /> ! , • 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 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 /> leading ed e.of flashing-must butt against up <br /> per row of nails to prevent fuming <br /> when torqued. <br /> 4 Lineup 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.1007140 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 thewasher <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 shell check capacity of rafter to support lag screw loading. <br /> wwwecofastensolarcom info@ecofastensolarcom 877-859-3947 4 <br />
