This is a manufacturer's nameplate/specification sheet for a Carrier air conditioning unit, Model 30HK-050-D-610, Serial Number 2801G00606, factory charged and listed as a liquid chiller self-contained unit.

The unit features two compressors operating at 460 volts AC, three-phase, 60 Hz. The primary compressor has a rated load amperage (RLA) of 39.0 amps and locked rotor amperage (LRA) of 223 amps, with a high-side design/test pressure of 385 PSI (2654 kPa). The secondary compressor operates at 26.0 RLA and 142 LRA, with a low-side design/test pressure of 235 PSI (1620 kPa). The system uses R-22 refrigerant. The power supply operates at 460 volts maximum with a permissible range of 506 volts maximum and 414 volts minimum, requiring 3-phase, 60 Hz power. The unit specifies minimum circuit amperage of 74.8 amps with a maximum overcurrent protection device rating of 110 amps. The nameplate explicitly states the unit is "not suitable for outdoor use" and requires minimum clearance to combustible materials when an electric heater is installed. Additional installation requirements include testing with external static and charging the system per manufacturer installation instructions.
