OPERATION:
The compressor is a 380VAC three-phase variable-capacity scroll compressor that is approved for use with HFC410A refrigerant. The compressor, when connected to an inverter, is capable of operating in a running frequency range from 22 hertz up to a maximum of 70 Hertz (maximum hertz is dependent on compressor size). The compressor speed is determined by demand from the room thermostat.
