NOTES:
• Normal operation:
– Cooling and dry mode
• Below 3 hours from the compressor stop and the compressor thermistor ≥ 59 °F (15 °C)
• After defrost operation
– Other than when the compressor starts for the first time since the breaker turns on
• Special operation:
– Other than the normal operation condition
– →hen the compressor starts for the first time since the breaker turns on
