I. Quick Rack Components Quick Rack rail-free mounting system features QRack® technology. With only 3 main components and an optional skirt, the system works with standard module frames and features Quick Mount PV’s high-quality, patented Elevated Water Seal to ensure a long, watertight life on the roof. Components are pre-assembled and ready for installation right out of the box. 1 2 Base Mount Panel Clamp 3 4 Optional Grounding Lug Skirt Featuring Quick Mount PV’s patented Elevated Water Seal.

III. Array Layout Using your engineered design, locate array layout on the roof, and determine mount locations. See pages Ref-4 - Ref-14 for span tables, wind exposure categories, cantilevers, and engineering rules. See page Ref-2 for alternative Snow Country Installation Requirements. 1 2 Mark off the locations for the bottom row of mounts. The penetration point for the first row is typically 3" up from the butt of the shingle. Locate rafters that will receive a mount.
IV. Installing the Mounts Tool Specs: Drill, roofing bar, 1/8" x 6" drill bit, T-30 Torx bit or 1/2" socket, appropriate sealant Screw Embedment Specs: 2.5" minimum embedment into rafter 2 1 3 Use roofing bar to break seals between 1st and Holding the drill square to the rafter, drill 3" deep Fill pilot hole with appropriate sealant. 2nd, and 2nd and 3rd shingle courses. Be sure pilot hole into center of rafter using 1/8" aircraft to remove all nails to allow correct placement extension bit.
Additional Info Mounts Additional Tips and Information n It is not necessary or advisable to use nails or other fasteners to secure the perimeter of the flashing. n The Base Mount is made to work with standard and high-definition composition/asphalt and wood shingle roofs with 5" to 5-5/8" courses.
V. Leveling the Mounts Tool Specs: 1/2" socket and torque wrench Torque Specs: Top slider bolt = 6 ft-lbs The modules in the Quick Rack system are unified by rigid panel clamps into a single flush surface, so small dips and curves in the roofs surface may not be visually apparent. However, mounts that are close together should be level with each other. To reduce time on the roof, use your own judgment about where a dip is significant enough to require leveling to maintain a smooth looking surface.
VI. Installing the Clamps Tool Specs: 1/2" open end wrench The modules are connected to the base mounts using 2" panel clamps, which can act as both mid clamps or end clamps, see step 3. The 8" panel clamps are used to bridge modules together. 8" panel clamps can either be floating, or attached to a base mount when the rafters align with a module intersection. Panel clamps include integrated grounding pins. See page Ref-17 for grounding information. 2 1 Install all panel clamp assemblies.
Installing the Clamps & Skirt in the First Row Only the front row needs to be aligned and locked down in order to assure a straight and secure skirt and array. All other panel clamps in the following rows do not need to be aligned or locked into the base mounts. See page Ref-2 for alternative Snow Country Installation Requirements. Skirt snap channel 2 1 3 For the first row, clamp must be oriented with Use 1/2" open end wrench on mid-clamp Align first row of clamps using a string line.
VII. Installing the Modules Tool Specs: 1/2" socket and torque wrench Torque Specs: Panel Clamp = 13 ft-lbs 1 Insert the bottom edge of the module frame into the lower clamps. The top of the module sits on the lower portion of the clamp assembly for the row above. 2 Where 2, 3, or 4 modules need to be connected, slide the 8" panel clamp over the module frame. The 8" clamp can either be floating or attached to base mount if the rafters line up. See below for proper module gap and clamp placement.
VIII. Wire Management Tool Specs: Wire clips, flat head screw driver, 5/16" socket and torque wrench Torque Specs: Grounding lug bolt = 35 in-lbs, grounding lug set screw - see below 1 2 Complete wire management on a row-by-row Before connecting the modules together, be sure basis.

Additional Info Wire Management Wire Clip Recommendations Rail-free systems are dependent on wire management clips that hold securely to both the wires and the module frames. After extensive testing, we recommend the following products with this system.
Reference The Span Tables, Wind Exposure Category Table, and Rafter Attachment Pattern Figures beginning on page Ref-4 are subject to the requirements shown in the table footnotes and to the following criteria. See Quick Rack V1.1-2 Base Mount Code Compliance Report dated 1-03-2017 by Mar Structural Design if additional information is required.

Installation Specifics, cont'd Each Quick Rack base mount is fastened to the roof rafter with one 5/16" nominal diameter structural screw, defined as either a 5/16" nominal diameter GRK RSS screw with Climatek coating or a 5/16" nominal diameter QMPV Dual-Drive screw, each pre-drilled with an 1/8" pilot hole to prevent splitting. The structural screw shall be embedded at least 2.5" into the roof rafter.
Snow Country Installation Requirements, cont'd n n BI 7.2.3-28 • At any bottom row of mounts, clamps shall be installed on top sliders so that the center of the machine bolt into the top slider is 1.5" upslope from the center of the top slider. • For subsequent rows of mounts, clamps shall be installed so that the center of the machine bolt into the top slider shall be installed no more than 1.5" upslope or 1.0" downslope from the center of the top slider.
