Page 7Detailed Installation ProcedureA. Floor Layout Panels1. Refer to the ATU floor layout drawing. This drawing provides an overalldimensional view of the major structural elements of the ATU building, withoutthe RF components. This drawing also shows the placement of the input andoutput panels relative to the rest of the building.2. Locate the 4’ x 8’ x 1/8” Hardboard panels that will be used as a layout pattern forthe floor of the ATU RF components. Referring to the ATU floor layout drawing,the panels should be placed tightly together leaving no spaces between the panels.The proper placement of the components has been marked on the panels, andthese markings can also be used as a guide to ensure that the panels are correctlyplaced. Duct tape or similar adhesive tape may be used to secure the Hardboardpanels into place, once they have been all correctly placed.Note the location in the drawing for the “Reference Corner”, and the locations ofthe RF input and the RF output for the ATU building. Also refer to the photos ofthe factory mockup of the system for which the components have been removedfrom the floor, leaving only the Hardboard template.3. After the Hardboard layout pattern is fully assembled and secured, pre-drill all themarked hole locations for each panel with a 5/16” nominal drill bit throughHardboard material and copper if necessary. Make sure the holes are drilledvertical to the floor and are drilled completely through the Hardboard, and thenusing 1/4” masonry drill bit (or nearest size that corresponds to the concreteanchor bolt sizes that will be used.), drill anchor holes in the concrete floor usingHardboard template. The holes must be drilled to the appropriate depth dictatedby the concrete anchors being used to secure the panels to the concrete floor.4. When all of the marked hole locations have been pre-drilled, remove theHardboard sheets one at a time. As each Hardboard sheet is removed, mark eachcomponent number on the floor for the placement of each component.5. Make sure all of the mounting holes have been drilled to the correct depth for allmounting holes in the floor. When all the holes have been drilled, clean out thedebris from the holes with a vacuum cleaner. Then, install the hardware anchorsinto the holes in the concrete for each component panel. To ensure that all of theholes have been included, do this for only one component panel at a time.
