6. 11 e TRANE 12 Application Considerations Unit Location Units should be installed indoors where exposure to rain or water splash is minimal A level foundation or flooring must be provided which will support at least 150 percent of the operating weight of the unit The chiller foundation must be rigid to reduce vibration transmission to a minimum Use of vibration isolators is recommended for applications with sensitive vibration and noise criteria Allow service clearance for compressor removal as well as evaporator and condenser tube removal Condenser Water Limitations Water cooled scroll chillers start and operate satisfactorily over a range of load conditions with uncontrolled entering water temperature Reducing the condenser water temperature is an effective method of lowering the power input required However by reducing the condenser water temperature beyond certain limits the effect causes a reduction in the pressure drop across the thermal expansion valve to a point when system instability may occur In general continuous machine operation with entering condenser water temperature below 60 F 15 5 C is not recommended When the condenser water temperature is expected to drop below 60 F 15 5 C it is recommended that some form of condenser water temperature control be used to ensure optimal machine performance Water Treatment Use of untreated or improperly treated water in chillers may
