This document is an Addendum for the Midwest City Library Chiller Replacement project in Oklahoma, specifically detailing mechanical equipment schedules for the HVAC system replacement. The documentation provides comprehensive technical specifications for multiple system components, including a 130-ton air-cooled scroll chiller (CH-1), two chilled water pumps (CHP-1 & 2), an air separator (ADS-1), a glycol make-up unit (GF-1), and a hydronic expansion tank (ET-1). The chiller is specified as a Trane CGAM 130 model with specific performance requirements, including a 15.93 NPLV efficiency rating, 460/3 voltage electrical specifications, and operational parameters for ambient temperatures up to 105°F.

The technical specifications include detailed requirements for each component, such as providing hail guards, a BACnet interface, a 30% polypropylene glycol solution, connection to an existing building automation system, and specific electrical and operational characteristics. Additional notes outline installation requirements like shaft grounding rings, epoxy base grouting, valve replacements, expansion tank modifications, and removal of existing chilled water pump infrastructure. The project appears to be a comprehensive mechanical system upgrade focused on improving the library's HVAC performance and efficiency through targeted equipment replacement and system integration.
