THIS IS NOT A WORK CHANGE DIRECTIVE, CHANGE <br />ORDER, OR A DIRECTION TO PROCEED WITH THE WORK DESCRIBED IN THE <br />PROPOSED MODIFICATIONS. <br />Description: <br />AE2S requests pricing from Magney for the re -location of condensing unit CU-3. The <br />manufacturer -provided plate settler cover and radon vent were removed from the <br />design. Due to this the CU-3 unit needs to be increased in size to handle the additional <br />load and the new unit will create more heat. Due to these issues, the CU-3 unit needs to <br />be moved outdoors. It was determined to locate the unit on the lower roof above the <br />chemical rooms. <br />Please provide pricing for the following: <br />1. Revise CU-3 location outside on roof. See marked up mechanical roof plan on <br />Page 2 of reviewed condensing unit submittal #067A. Verify exact location prior <br />to installation. Maintain all required service clearances to unit and adjacent <br />equipment on roof. <br />2. Coordinate unit interface with equipment curb/rails and flashing with the roofing <br />contractor. Refer to architectural details. <br />3. Provide vibration isolation in accordance with Section 23 05 48. <br />4. Revise refrigerant piping route and control wiring connections between MAU-3 <br />DX coil and CU-3 through plate settler corridor. Verify line set sizes and <br />elevations with manufacturer requirements. <br />5. Delete concrete pad below CU-3 in previous location. <br />
