Trane, in offering the Trane Air Conditioning Economics (TRACE^TM700) computer program, accepts no responsibility or liability for the design of buildings or their support systems or for the accuracy of the economic analysis and the building and system air conditioning load data. The economic analysis and the building and system air conditioning load data are based on conventional economic and engineering principles, plus financial and engineering data supplied only by the program user. This TRACE 700 program is intended to be used as a comparative study of operating efficiencies and costs of alternative air conditioning systems. Trane further accepts no responsibility or liability for the suitability of the building air conditioning system in providing proper temperature control, humidity control, infiltration, air distribution and quiet operation.
