    Tools and Materials Required: (Not supplied by KTL): 1. Duct Tape or similar adhesive tape, for securing the floor layout panels 2. Masonry drill bits, suitable for drilling in concrete (¼” or metric equivalent and recommended) 3. Vacuum cleaner for cleaning out drilled holes in concrete. 4.

  • Page 6: General Instructions

    General Instructions These instructions are to be used in conjunction with the final drawing package for the ATU Network supplied by Kintronic Labs (KTL) for installation at the tower base. Before beginning the actual installation process, it is recommended that these instructions be read through in their entirety, and also that the drawings referred to in the instructions are reviewed in connection with the specific steps in which these drawings are referenced.
  • Page 7 Measure all dimensions of the building interior, and compare to the dimensions as indicated on the relevant drawings. In particular, measure the interior width of the building at both the front end and at the rear end of the building, and also measure the interior depth of the building on both right and left sides of the building.

  • Page 8: Overview Of Installation Steps

    Overview of Installation Steps Before presenting the detailed installation steps, the present section presents an overview of the basic approach that will be taken in the installation of the RF equipment into the ATU building. The basic steps to be taken are as follows: 1.

  • Page 9: Detailed Installation Procedure

    Detailed Installation Procedure A. Floor Layout Panels 1. Refer to the ATU floor layout drawing. This drawing provides an overall dimensional view of the major structural elements of the ATU building, without the RF components. This drawing also shows the placement of the input and output panels relative to the rest of the building.

  • Page 10: Critical Overview Of Component Installation

    B. Critical Overview of Component Installation 1. This is an important overview section, which will make it easier to identify each RF component in the system, and also ensure that each component will be located in its proper position and orientation. While going through this overview section, refer to the RF schematic and Component Layout Drawing.

    4. While using the factory mockup photos as a guide, trace through the RF schematic for the ATU system, starting at the RF input, and working through to the RF output. As the components are identified in the RF schematic, the corresponding location of the component should be identified in the component layout drawing, and also observed in the corresponding photo(s).

  • Page 12: Installation Of Copper Pipe Bus-Work

    E. Installation of Copper Pipe Bus-Work 1. Locate the copper pipe for the RF components. Each piece of copper pipe is labeled on the outside of the protective wrapping to show which components are to be connected with that particular piece of pipe. When you remove the protective wrapping you will see that each end of the pipe has also been marked so as to indicate the component that it connects to on that end of the pipe.

  • Page 13: Installation Of Vacuum Capacitors

    F. Installation of Vacuum Capacitors 1. Reserve the actual installation of the capacitors themselves until it is absolutely necessary. This will help prevent damage to the capacitors. The vacuum capacitors used throughout this system are both fragile and expensive. They should be handled carefully to prevent damaging them.

  • Page 14: Installation Of Auxiliary Equipment

    G. Installation of Auxiliary Equipment 1. Locate the remote meters for the input and output RF current. 2. Each meter has been calibrated together with its toroid and cable as a matched set. Use the serial numbers to match each meter with the correct transformer. 3.
