pitched roof tops.The system is designed to ensure it withstands severe weather conditions and meet the local and international building codes, and yet enables solar contractors to install solar PV systems easily, and reduce installation time and overall installation cost. The system is designed to simplify the installation process with fewer part and easy access,and helps reduce installation time. 1.1 Magerack Mounting System and Components A mounting system mainly consists of three parts, attachments that secure the mounting system to the roof, rails that support PV module and clamps that secure module to the rails.

Rails can be laid out horizontally or vertically depending on the layout of solar modules.Solar module can also be installed in portrait or landscape layout.See illustration. Determine Rail Span The tables from the Engineering Certification Letter in Appendix illustrate the maximum rail span (spacing between attachments) under different conditions.When you design the rail span, make sure to consider wind speed,snow load, topographic factors and other factors and your design should be adequate to withstand the weather conditions in the area. 2.2 Select Attachment Type Roof Type and Attachment Selection Appropriate attachment should be used based on roof type. For asphalt shingles, L-foot is the best choice. It is easy and quick to install. For tile,shake or high-profile composition roof or new roof,standoff may be the best choice due to height requirement. For high-profile tile,tile hook can be used as well, 2.3 Calculate Total Mounting Components Needed Portrait Layout The following table shows number of rails and components needed per row,the table is based on the portrait layout and the width of the PV module is up to 39.5".

Rail span Based on the number of modules,calculate the total length of each row. Remember to add the space for mid and clamps.Add 0.79"for each mid clamp and 0.87"for each end clamp.The total length will be as follows, Length of row=module width *no.of modules+0.79*(no.of modules-1)+0.87*2 E.g., if a row has 6 modules and the module width is 65", the total length will be as follows, Length of row=65 *6+0.79 *5+0.87*2=395.69" The number of attachment per row is as follows, No.of attachment=round(length of row/span—0.67) If the maximum rail span is 6 feet(72"),the number of attachment per row is as follows, No.of attachment=round(395.69/72—0.67)=round(4.83)=5 5 attachments will be needed for each row. 9 Chapter 3 Install Attachment Due to variety of roof types and conditions, all Magerack roof attachments do not come with roof fasteners. Installer needs to check the roof condition and building codes requirement to decide the appropriate lag screws or roof fasteners to make sure the lag screws or roof fasteners are adequate to secure the attachment to roof structural elements. Please refer to the engineer letter in the Appendix about depth of penetration or consult with structural engineer or local building code for proper lag screw that should be used for L-foot,standoff and tile hook. 3.1 L-foot For composition roofs, L-foot is the choice for simple,easy and quick installation of roof attachment.When install L-foot, make sure L-foot is secured to the rafter with adequate lag screws or through bolts.5/16 or 3/8 lag screws or through bolts should be used. Installer should decide what lag screws should be used to secure L-foot to the rafter. Make sure the lag screw is penetrated into the rafter deep enough.See Appendix for minimum depth of penetration or consult with structural engineer or local building code for proper lag screw that should be used.When install L-foot to the roof,follow building codes requirement to apply roofing sealant to the underside of L-foot base and into bolt holes. Locate L-foot Attachment Position ,++ L-foot must be secured to roof rafter. Please use appropriate lag screw or through bolts to secure L-foot to the raft. 5/16 or 3/8 lag screw or through bolts should be used. Drill pilot holes to locate rafter and avoid rafter split. Secure L-foot When securing L-foot to rafter, roofing sealant may be applied to the backside 1 of L-foot for additional waterproofing.After L-foot is secured with lag screw through the slot hole, do not tighten the lag screw so you can adjust the L-foot position by moving L-foot vertically. Install all L-feet on the same row. After all the L-feet on the same row are secured to the roof, adjust them to make sure all L-feet are properly aligned.After adjustment is completed,tighten the lag screws. L-foot Flashing For additional water proofing,the L-foot flashing must be installed.Slide the top of flashing under the upper roofing material and move flashing all the way up until the bottom of flashing is right above L-foot base. Make adjustment so that the flashing is centered horizontally above L-foot. Make sure the roofing material must be overlapping over the flashing top.Secure flashing to L-foot with provided 5/16 bolt. 10 When it is necessary,flashing can be further secured to the roof with roofing nails. Lift or remove upper roofing materials, nail flashing to the roof on the top portion of the flashing and then return upper roofing materials to the original position and cover the top of flashing. 3.2 Standoff For tile,shake or stone-coated metal roofs,or solar panel need to be installed higher,standoff can be used as attachment. When install standoff base,make sure the standoff base is secured to the rafter with adequate lag screws or through bolts. 5/16 or 3/8 lag screws or through bolts should be used. Installer should decide what lag screws should be used to secure standoff base to the rafter. Make sure the lag screw is penetrated into the rafter deep enough.Consult with structural engineer or local building code for the proper lag screw or roof fastener that should be used.See Appendix for minimum depth of penetration or consult with structural engineer or local building codes for proper lag screw that should be used.When secure standoff to the roof,follow building code requirement to apply roofing sealant to the underside of standoff base and into bolt holes. Locate Standoff Attachment Position Standoff must be secured to roof rafter. Please use appropriate lag screw to secure standoff base to the raft. 5/16 or 3/8 lag screw or through bolts should be used. Drill pilot holes to locate rafter and avoid rafter split. Secure Standoff When securing standoff to rafter,roofing sealant must be applied to the backside of standoff base. Install all standoff on the same row and make sure they are properly aligned horizontally,and then tighten all standoff bases on the same row. Install the small L-foot for standoff with provided 5/16 bolt.The slot hole is attached to the top of the standoff shaft.You can make adjust by moving the L- foot vertically to ensure all the standoffs in a row are aligned properly.Tighten all bolts to 12 ft-lbs. u s Y Flashing Use traditional cone-shaped flashing such as Oatey flashing and follow manufacturer's instruction to install cone-shaped flashing properly.Secure flashing to the roof with fasteners or adhesive in compliance with local or international building code, or instruction from roofing material manufacturer.Slide rubber rain collar through standoff shaft. { 3.3 Tile Hook For high-profile tile or shake roofs,tile hook can be used as attachment.When install tile hook base, make sure the tile hook base is secured to the rafter with adequate lag screws or through bolts.5/16 or 3/8 lag screws or through bolts should be used. Two 5/16 or 3/8 lag screws or through bolts should be used to secure tile hook base to the roof and they should be used vertically aligned through any two vertically aligned holes on the tile hook base. Tile hook and tile hook base are attached with provided two(2)5/16 bolts and nuts with lock washers.Tile hook can be mounted to any two adjacent holes on tile hook base, so there are three choices. i Installer should decide what lag screws should be used to secure tile hook base to the rafter. Make sure the lag screw is penetrated into the rafter deep enough. Consult with structural engineer or local building codes for the proper lag screw or roof fastener that should be used.See Appendix for minimum depth of penetration or consult with structural engineer or local building codes for proper lag screw that should be used.When secure the tile hook base to the roof,follow local building code requirement to apply roofing sealant to the underside of tile hook base and into bolt holes. Locate Tile Hook Attachment Position u j Tile hook must be secured to roof rafter. Please use appropriate lag screw to secure tile hook base to the e raft.5/16 or 3/8 lag screw or through bolts should be used. f Remove tiles where tile hook base will be attached.Try tile hook and tile hook base at different positions and find out the best location so that the tile hook can be secured to rafter and tile hook is above the middle valley of underlying tile. After positions for tile hook and tile hook base are determined,tighten the tile hook and tile hook base with provided two 5/16 bolts and nuts to 19 ft-lbs. Secure Tile Hook Base When securing tile hook to rafter,roofing sealant must be applied to the backside of tile hook base. Install all tile hooks on the same row and make sure they are properly aligned horizontally. Do not tighten the lag screw yet so you can adjust the tile hook position by moving tile hook base vertically. F 12 d After all the tile hooks on the same row are secured to the roof,adjust them to make sure all tile hooks are properly aligned. After adjustment is completed,tighten all fasteners. Flashing Move the tiles back to the original location. If necessary, installer may need to cut the tiles to fix around tile hooks. If double flashing is required, roofing paper or aluminum sheet may be used to cover the tile hook base after it is secured to roof rafter. 13 Chapter 4 Install Rail and Rail Connector 4.1 Install Rail Rail is mounted to the attachment through L-foot, the small L-foot on top r— of the standoff or tile hook. For L-foot, rail can be mounted on either side —____,— -- of the L-foot depending on your preference or convenience. For the small t� — L-foot on top of the standoff or tile hook, rail should be mounted as shown. Rail is installed to roof attachments through rail nut.Slide rail nut into rail channel from either end of the rail or push rail nut inside the rail channel. j Mount rail to attachment with 5/16" bolt provided. Don't tighten the bolt yet. Install all rails along one row. 4.2 Install Rail Connector To connect two rails, insert the rail connector nut into the rails and mount the — rail connector with the rail connector nut using provided 5/16" bolt. For consideration of thermal expansion, leave a 1/4"gap between rails.Tighten all 5/16 bolts to 12 ft-lbs. 4.3 Level and Tighten Rail Before tightening all bolts to the attachment,adjust the rail up and down by moving rails vertically along the attachment slots. Make sure all rails in two rows where solar panel will be mounted are leveled and the top of rails are in the same surface. Tighten all bolts to 12 ft-lbs. 14 Chapter 5 Install Wiring, Grounding and Accessories After mounting rails are installed,depending on the design,wiring and grounding may need to be prewired before installing solar modules. In addition,other elements of the solar system such as junction box or micro-inverters may need to be preinstalled as well. Follow the design and make sure all elements under the solar modules are positioned or preinstalled. 5.1 Install Microinverter Mounting Kit Locate Attachment Points For the convenience of installing grounding wire or microinverter,optional microinverter mounting kit can be installed.The mounting kit can be installed anywhere along the rail.The mounting platform can be installed either way as shown. • ♦ i ♦ 5.2 Install Wiring, Grounding and Accessories Before mounting solar modules,it may be convenient to install all the wiring,grounding or other solar system elements. Please refer to the corresponding installation instructions to install wiring,grounding and accessories. 15 i Chapter 6 Install Solar Module The solar module should be installed from one end to the other on each row. For each solar module there should be four clamps. If the module is the first or last module in a row,it is secured with two mid clamps and two end clamps. If the module is in the middle of a row,it is secured with four mid clamps. Each mid clamp secures a two modules, one on each side. Each end clamp secures one module only. 6.1 Set up End and Mid Clamps Before installing solar panel,slide in the end clamps and connect end clamp top with bottom using provided bolt. Make sure the end clamp size matches the solar panel thickness.Similarly, slide the mid clamps to the appropriate location and connect the mid clamp top with bottom using appropriate provided bolt.The mid clamp can also be pressed into the top of the rail,which is convenient when installer forgets to slide the mid clamp in the rail before they install solar panels. 6.2 Mount Solar Modules After positioning the first solar module on the rails, line up the position and then secure it with two end clamps.After that, position the second module and secure the first and second module with mid clamps. Continue to install all the models until the last module is positioned,which will be secured with two mid clamps on one side and two end clamps on the other side.After one row of solar modules is installed,tighten all the bolts to 12 ft-lbs. 16 6.3 Connect Wiring and Grounding Connect wiring,grounding and other accessories per solar module manufacturer's specifications. 17 Chapter 7 Finish Installation 7.1 Trim Rail Trim excessive rail on both end. Make sure to leave half inch of rail space beyond end clamps. 7.2 Check All Bolts Check and tighten all 5/16 bolts to 12 ft-lbs.
