•Evaporator - The evaporator is a brazed plate heat exchanger where the liquid refrigerant is allowed to evaporate (boil off) to absorb the heat (BTU) from the process fluid. As the heat is absorbed, the process fluid is chilled.
•High/Low Pressure Switches: The high/low pressure switches protect the refrigeration system from unsafe operating levels. The high pressure switch is factory set to open at 230 PSI and protects the refrigeration components and personnel from potential damage or injury from excessively high pressure. The high pressure safety must not be altered in the field for any reason. The low pressure switch is factory set to open at 25 PSI and to close at 35 PSI. The low pressure switch protects the chillers from possible damage due to low operating pressure. The low pressure switch is field adjustable for setpoints below 45°F {7.2°C}, contact a Conair representative for more information.
IMPORTANT: Altering the High Pressure Switch setting will void any chiller warranty.
✐NOTE: The fan cycling switch is adjustable when the chiller
is in an environment cooler than 95°F {35°C}. See Appendix J entitled, Plumbing Schematic.
