  • Page 26 CF Series Portable Chiller : Air & Water-Cooled : 5 - 40 Tons Compressor Pump’s Electric Motor Pump electric motor and compressors located on typical water-cooled unit. Caution must be taken when checking rotation to avoid electrical shock. A scroll compressor may make a loud rattling noise when rotating in the wrong direction.
  • Page 27 CF Series Portable Chiller : Air & Water-Cooled : 5 - 40 Tons Observe the motor shaft. When the ON/ OFF SWITCH is on, the motor shaft will rotate. When switched off, the shaft will slowly “coast” to a stop. As the shaft slows, the operator can identify the rotation of the motor shaft.
  • Page 28 CF Series Portable Chiller : Air & Water-Cooled : 5 - 40 Tons PROCESS FLOW ADJUSTMENTS The operator must determine and set proper water flow rate for the most efficient and trouble free operation. Water flow rate through the process is determined by the pressure losses in the process loop. Generally, higher flow rates result in turbulent flow achieving maximum temperature control and lower maintenance. Since the evaporator in most liquid chillers is flow sensitive, the efficiency of operation is directly related to the flow of liquid. Maximum chiller efficiency is obtained at approximately 2.4 gpm per ton of rated capacity. Low liquid flow can reduce efficiency and in some cases allow ice to develop in the evaporator which can damage the evaporator. Excessive liquid flow will trip the motor overload protection...
