About this file
This mechanical drawing sheet from Rex Putnam High School in North Clackamas School District details specifications for a chiller replacement project, including mechanical schedules, pump details, and control diagrams. The document includes detailed specifications for a new Trane Ascent Air Cooled Chiller (Model ACR) with 298.5 tons capacity, three pumps (CHWP-1, HWP-1, and HWP-2), and associated mechanical systems. The drawings show mechanical legends, symbols, pump details, and control diagrams for chilled water and heating water systems.
The specifications call for specific equipment including a Bell & Gossett base-mounted centrifugal pump for the chilled water system (CHWP-1) rated at 700 GPM and 85 ft head pressure, and two heating water pumps (HWP-1 and HWP-2) rated at 680 GPM and 340 GPM respectively. All equipment must meet the 2021 Oregon Energy Efficiency Specialty Code requirements. The chiller specifications include single-point power connection, factory-powered GFCI convenience outlet, and detailed electrical requirements (460V/3PH, 496.0 MCA, 600.0 MOCP). The document includes specific installation requirements such as 4-inch housekeeping pads for certain pumps and detailed control diagrams for system operation.
