1 91961OPR GENERAL INFORMA TION INTRODUCTION Remcor “CH” Series Refrigerated Recirculating W ater Chillers are designed to provide a continuous flow of clean cooling water at a constant temperature and to handle a variety of closed loop and tank cooling applica- tions.
2 91961OPR INST ALLA TION LOCA TION Install the Chiller indoors in a well ventilated area where ambient temperatures will never fall below 40 F or rise above 1 10 F . T o obtain optimum cooling capacity , the ambient temperature should be 80 F or below .
3 91961OPR ELECTRICAL All wiring must conform to the National Electric Code and any applicable local codes. The Chiller must be PERMANENTL Y 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.

This light cycles on and of f in response to the thermostat. 5. HIGH PRESSURE ALARM LIGHT - A red light that indicates high refrigeration pressure.
10 91961OPR MAINTENANCE CAUTION: Disconnect electrical power before performing any of the following maintenance procedures. The Chiller will require very little normal maintenance.
11 91961OPR FLUID RECOMMENDA TION Chillers are designed to operate with water to provide maximum performance for tempera- tures of 40 F–100 F.
12 91961OPR W ARNING: If repairs are to be made to the refrigeration system, make sure electrical power is disconnected from the unit. TROUBLESHOOTING IMPORTANT : Only qualified personnel should service internal components or electrical wiring. T rouble Probable Cause Remedy CHILLER DOES NOT OPERA TE.
