CH1001-A Chiller Operator’s & Installation Manual GENERAL INFORMATION INTRODUCTION The Cornelius ”CH” Series Recirculating Water Chiller is designed to provide an accurate, reliable, and userfriendly system for cooling a continuous flow of pure liquid and keep that liquid at a constant temperature in various closed loop or tank cooling applications. The ”CH” Series Chiller consists of an air–cooled refrigeration system housed in a sturdy sheet metal frame and cabinet.
CH1001-A Chiller Operator’s & Installation Manual When servicing a Cornelius Chiller, it is important to note the information contained on the data plate located in the upper rear of the Unit. If technical assistance is needed, the phone technician will need the Serial Number of your chiller. That information is found on the Data Plate along with the model number, voltage requirement and refrigerant information.
CH1001-A Chiller Operator’s & Installation Manual The data plate, located next to the junction box, includes the actual voltage, phase, and amerage of the chiller. CAUTION: On three-phase applications, it is important that the rotation of the pump, when supplied , is correct. Operating the pump in reverse for more than a few seconds will result in permanent pump damage. When the pump is operating, the shaft rotation must match the direction indicated on the pump housing.
CH1001-A Chiller Operator’s & Installation Manual Control Power Switch/Light A lighted ON/OFF pushbutton switch, shown in Figure 3, is used to switch power to the 24VAC control circuit. The switch illuminates to indicate that the chiller power is present. Bypass Light (Blue) A blue light, shown in Figure 3, is used to indicate when the system is operating at a reduced capacity. The light cycles on and off in response to the temperature controller when the system temporarily requires less cooling.
CH1001-A Chiller Operator’s & Installation Manual Process water flow can be adjusted via a throttling valve and flow meter installed in the chiller outlet line. Once the flow has been established, the thermostat can be programmed to the desired set-point.
