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.
It is very important that the air intake and discharge sides of the chiller are not obstructed by other free standing objects. A minimum of two feet of space on all four sides of the chiller will be sufficient to prevent air flow obstructions. It is also important to direct any hot air discharge from other equipment away from the air intake side of the chiller. Condenser air entering the “CH”unit should be below 100_F (38_C) .
Chiller Operation WARNING: NEVER OPERATE THE CHILLER WITH THE PANELS REMOVED. USED. ALWAYS USE THE POWER SWITCH TO TURN OFF THE CHILLER WHEN IT IS NOT BEING ALWAYS ENSURE THAT ALL AIR INLETS AND OUTLETS ARE FREE FROM OBSTRUCTION. BE SURE THAT THE RESERVOIR IS FILLED WITH FLUID PRIOR TO POWERING UP THE UNIT. Process Liquid Flow After ensuring that the system piping is free from obstruction, that all valves are open, and the reservoir is full, push the CONTROL POWER switch to the ”ON”position.
COOLING OPERATION REMCOR CHXXX SERIES CHILLER CONTROL COOLING POWER SAFETY CONTROL PANEL RED INDICATOR GREEN INDICATOR WHITE INDICATOR/PUSH BUTTON FIGURE 2. CONTROL PANEL Temperature Indicator/Controller (Thermostat) Combines a precise temperature control and easy programmability with a convenient LED temperature readout that indicates system liquid temperature (2_F Differential). To adjust thermostat, see next section. 1.
START--UP IT IS IMPORTANT THAT THE LIQUID LEVEL SIGHT GLASS READS ”FULL”. IN THE EVENT THAT THE RESERVOIR IS EMPTY, THE UNIT WILL REMAIN OFF UNTIL AN ADEQUATE LEVEL OF LIQUID IS ATTAINED. MAKE SURE CHILLER POWER IS ”OFF” PRIOR TO FILLING RESERVOIR. Push CONTROL POWER button IN. All alarm indicators should be extinguished and the Chiller system will cycle in order to maintain the established set-point. The Chiller is now ready for normal operation. Thermostat Control up down 7 0 _F out set FIGURE 3.
Pump Motor The PUMP MOTOR should be lubricated with thirty drops of SAE 20 oil once a year. Circulation System The CIRCULATION SYSTEM should be drained and flushed periodically to avoid build up and possible flow restriction caused by contaminants. Filters/Strainers The FILTER located inside of the unit at the inlet of the pump should be cleaned periodically depending on applications.
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. TROUBLE CHILLER DOES NOT OPERATE, CONTROL POWER LIGHT “OFF” PROBABLE CAUSE REMEDY A. No Power To Unit. A. Check Main disconnect fuses, wiring, and power lead to unit. B. Defective Control Power Switch. B. Replace Switch C. Defective Control Transformer. C.
TROUBLE CHILLER DOES NOT OPERATE, BUT COOLING LIGHT IS “ON”AND 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. B. Unit is operating under low pressure conditions. B. Check sight glass, if bubbles are seen, leak check unit and recharge with refrigerant. or If no bubbles are seen, replace defective TXV. C.
