Please refer to option 6 for evaporator leaving water low-temperatureapplications (< 5 °C).*** The minimum entering air temperature is based on the drycooler selection.**** The maximum entering air temperature is based on the drycooler selection.† For applications with a low condenser entering air temperature the use of athree-way valve is recommended. This thre-way valve can be controlled by the0-10 V analogue output of the Pro-Dialog+ control.30WG Minimum MaximumEvaporatorEntering water temperature at start-up °C 7.5* 27Leaving water temperature during operation °C 5** 20Entering/leaving water temperature difference K 2.5 7CondenserEntering water temperature at start-up °C 15*** 55****Leaving water temperature during operation °C 20 60Entering/leaving water temperature difference K 2.5 18* For entering water temperatures below 7.5 °C at start-up, contact Carrier.** If the leaving water temperature is below 5 °C, a frost protection solution mustbe used.
