SMC Series Chillers Page 37 8 Troubleshooting Guide Problem Cause Solution Chiller will not run. No power. Check main disconnect fuses, wiring, and power lead to the unit. Wrong voltage supplied to the chiller. Voltage must be within plus or minus 10% of the nameplate rating.
Page 38 SMC Series Chillers Problem Cause Solution Pump runs, compressor will not. Refrigerant is low. Check the refrigerant charge. Pressure switch contacts are open. Sight glass should be clear while compressor runs. Call for service if bubbling or foaming Refrigerant high pressure cutout switch contacts are open.
