About this file
This is a Preventative Maintenance Checklist for the City of Phoenix's chiller and boiler system maintenance contract, which specifies comprehensive maintenance tasks organized across ten functional sections. The checklist covers chiller and cooling tower maintenance, boiler and burner combustion system tasks, electrical and VFD cabinet operations, piping and water system leak checks, operational testing procedures, gauge documentation, oil system maintenance, pump and mechanical movement inspections, structural and physical inspections, and chemical system monitoring. Tasks are assigned frequency intervals ranging from monthly to annually and semi-annually, with specific equipment models identified including Boiler models 300S-850A, 300A-850A, and 850. The contract term is five years beginning on the Commencement Date as approved by the Phoenix City Council, with no options to extend, and will terminate upon reaching the end of the five-year term or earlier upon contract termination provisions.
The checklist provides a standardized framework for technicians and supervisors to document completion of required maintenance activities with designated spaces for dates and sign-offs. Monthly tasks include checking chiller and condenser pumps, water temperatures, cooling tower screens and belts, inspecting oil and Freon levels, cycling water control valves, and conducting chemical testing for hardness, alkalinity, chlorides, nitrite, phosphates, pH, conductivity, and biological activity. Pre-season tasks encompass chiller and heater boiler annual inspections with startup and shutdown procedures, oil system maintenance including filter changes and oil sampling, and VFD cabinet cleaning and tightening. The document requires technicians to record alarms, amp draws, pressures, temperatures, model and serial numbers, and provide monthly monitoring data in reports, with gauge recalibration required semi-annually for specific boiler models.
