'Arra6J 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;i.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 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 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` FLaSHinG InSTaLL <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 /> s, 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 Rock4t slide,the gasketed <br /> hole in the flashing and Into the rafter. <br /> Torque.The range is between 100-14p 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.ecofastensolar.com info@ecofastensolarcom 877-859-3947 4 <br />
