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 vari- ous 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. A standard pump and insulated liquid reservoir package provides a complete

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 ob- structions. It is also important to direct any hot air discharge from other equipment away from the air intake side of the chill- er. Condenser air entering the “CH”unit should be below 100_F (38_C) .Condenser air temperatures above 100 _F (38_C) can cause the high

Chiller Operation WARNING: NEVER OPERATE THE CHILLER WITH THE PANELS REMOVED. ALWAYS USE THE POWER SWITCH TO TURN OFF THE CHILLER WHEN IT IS NOT BEING USED. 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. The

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 re- striction caused by contaminants. Filters/Strainers The FILTER located inside of the unit at the inlet of the pump should be cleaned periodically depending on ap- plications. If a reduction in flow or cavitation of the pump occurs, remove the in--line FILTER, back-flush it with wate
