GENERAL INFORMATION INTRODUCTION The REMCOR ”CH” Series Recirculating Liquid Chiller is designed to provide an accurate, reliable, and user-friendly 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.
When servicing a REMCOR 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. The serial Number is also needed when replacement parts are being ordered or for warranty claims. See CHILLER WARRANTY PAGE.
Electrical Connections (see Figure 2 and 8) All wiring must conform to the National Electric Code and any applicable local codes. The Chiller must be permanently wired by means of electrical conduit to a properly fused disconnect of proper amperage or wired to a properly rated power cord and plugged into an outlet with the appropriate disconnect and amperage rating. The electrical junction box, located on the back panel of the Chiller, includes a four terminal strip for power supply connection.
2. CONTROL POWER SWITCH/LIGHT (see Figure 3) A lighted ON/OFF push button switch is used to switch power to the 24 VAC control circuit. The switch lights up to indicate that the Chiller power is present. 3. BYPASS LIGHT (BLUE) (see Figure 3) A blue light is used to indicate when the system is operating at a reduced capacity. The light will cycle on and off in response to the Temperature Controller when the system temporarily requires less cooling. 4.
that the shaft is rotating in the direction of the arrow indicated on the pump housing. If the rotation is incorrect, reverse two of the three incoming power supply leads at the terminal strip. NOTE: Operating the pump in reverse for more than a few seconds will result in permanent pump damage. All Chillers with pumps and tank are supplied with a pressure regulating valve on the pump discharge.
TEMPERATURE CONTROLLER OPERATION (see Figure 4) During normal operation, the process temperature will be displayed on the Controller. The following procedure should be followed to adjust the Controller set point: 1. Push and hold the “ *” button located at the bottom left corner of the Controller. The set point will be displayed. 2. While holding the “ *” button, press the desired value is displayed. (“ UP” ) or “ DOWN” button to raise or lower the set point until 3. Release the “ *” button.
Condenser On air--cooled Chillers, the CONDENSER FINS should be cleaned by blowing compressed air through the condenser from the fan side. Dirt and debris accumulate on the condenser fins over time, and this build up can severely reduce the performance of the Chiller. Cleaning of the CONDENSER COIL FINS should be done approximately every three months, depending upon cleanliness of your application.

TROUBLESHOOTING WARNING: Disconnect electrical power to the Chiller to prevent personal injury before attempting any internal maintenance. Only qualified personnel should service internal components or electrical wiring. If repairs to the Chiller must be made, disconnect electrical power to the unit, then shut off the water source. TROUBLE CHILLER DOES NOT OPERATE, CONTROL POWER LIGHT “OFF” PUMP DOES NOT OPERATE, BUT POWER LIGHT IS “ON”. UNIT RUNS CONTINUOUSLY, BUT IS NOT COOLING PROCESS LIQUID ENOUGH.
TROUBLE CHILLER DOES NOT OPERATE, BUT POWER LIGHT IS “ON” AND RED SAFETY LIGHT IS “ON”. PROBABLE CAUSE REMEDY A. Unit is operating under high pressure conditions. A. Check for dirty condenser fins or obstruction of chiller air intake. Press high pressure manual reset switch. If this problem persist, contact Remcor Service Department. B. Unit is operating under low temperature conditions. B. Low or no process liquid flow. Ensure that there is adequate flow through system plumbing.
