Page 7: Preparing For Installation
Preparing for Installation Clean roof surface and remove all dirt and debris. IMPORTANT Inspect roof for damage prior to installation and record any existing damage with a digital camera. Ensure proper drainage on the roof. Water accumulations may lower the load reserve of the rooftop and decrease lifespan. -
Page 8: Installing The Module Supports
Installing the Module Supports Place your first support for an array. Refer to your project specific Layout Diagram for dimensions (see example, Figure 3). IMPORTANT Wear safety gloves when handling parts. Newly fabricated parts may have sharp edges. Use your project specific Spacing Diagram to obtain the distance between two module supports in the N/S and E/W directions. -
Page 9: How To Use Your Layout Diagram
How to Use Your Layout Diagram Note the following items on your project specific Layout Diagram: NORTH ARROW DIMENSIONS LEGEND ARRAY NUMBERS ROOF STRUCTURES From the layout, use the N/S and E/W dimensions at a corner of your roof as the ORIGIN (i.e. the beginning) of your installation. Fig. -
Page 10: How To Use Your Spacing Diagram
How to Use Your Spacing Diagram Your Spacing Diagram will indicate the following important dimensions: N/S SUPPORT SPACING (N/S distance between supports) E/W SUPPORT SPACING (E/W distance between supports) ROW SPACING (N/S distance between support rows) Record these numbers and do not confuse them. OPTIONAL. -
Page 11: Installing Ballasts
Installing Ballasts IMPORTANT Place ballast blocks on module supports before installing panels to prevent panels from lifting. Use your project specific Paver Layout to place paver block combinations onto all module supports (see example, Figure 6). IMPORTANT Where possible, position pavers atop flanges of the module support base-plates. -
Page 12: How To Use Your Paver Documents
How to Use Your Paver Documents Ensure you have the Paver Layout and Paver Shading Diagram documents. The Paver Layout shows the combinations of blocks required for each support to ballast each panel. The Paver Shading Diagram shows sample arrangements of pavers to prevent shadows being cast onto the panels. -
Page 13: Installing Solar Panels
Installing Solar Panels Begin at an array edge. Place a solar panel onto the module support (Exx- 01B). IMPORTANT Strong winds can lift panels. Once installed, solar panels should not be left unsupervised without windshields (Exx-0xB) installed. Click KB konnect clamps (C02-xxE) into top and bottom mounting slots of module supports. - Page 14 IMPORTANT ® End blocks provided by KB Racking designed to match your solar module thickness. This ensures the clamp sits flat. If end clamps do not sit flat, you have the incorrect block size. Notify your builder immediately. Secure the first panel in the row. Tighten all clamps with a standard drill or torque wrench.
- Page 15 IMPORTANT When securing KB Konnect clamps, ensure EkonoRack support is firmly secured (by ballast or human weight). Failure to do so may result in damage to the support and/or clamp. Continue placing panels for your first row. Tighten KB Konnect clamps as panels are installed.
