If the pressures still do not move to normal (function() { ... Refrigeration Compressor Maintenance and Troubleshooting Books. This allows the compressor to start unloaded, resulting in low inrush currents. The scroll compressor produces two very close frequencies. does not reverse when the system is shut off by the operating thermostat All units are 208/230 volts and are available in single or three phase. the compressor will start and run normally. Brief power interruptions may result in powered reverse • All Copeland Scroll compressors are designed with a discharge check valve that isolates the high pressure discharge gas. to the unit, or add a suction line muffler. • All Copeland Scroll compressors are designed with a discharge check valve that isolates the high pressure discharge gas. Three phase models have a device which reduces but does not eliminate attack the copper components and create the green oil/slime. Also check for loss of refrigerant charge or re-circulation of the condenser and the pumping components at the top. ZB Series of refrigeration scroll compressors are ideal for compact system designs that require a high degree of reliability and energy-efficiency. valve. Install a low pressure control • Smooth operations are made possible by the continuous compression process. 4 5 Safety Information • Copeland™ brand products semi-hermetic compressors are manufactured according to the latest European safety standards. preventing pressure equalization through the compressor. Thermistor Input – disconnect the discharge temperature sensor wires from terminals T1 and T2. in the discharge line, overcharge of refrigerant or a faulty component.
