13. Error codes
1.When the sensor, which detect the evaporator temperature, is damaged(open circuit
or short circuit), the digital tube will show C1 and flashing. When NTC detect the
evaporator's temperature≥40℃ and last 2 minutes, the machine will stop working and the
digital tube will show C1 and flashing.
2.When the sensor, which detects the ambient temperature, is damaged (open circuit
or short circuit)、and when the sensor detects the ambient temperature ≤0℃ or ≥40℃,
the digital tube will show C2 and flashing, the machine will stop working. When the
temperature &humidity's connection wire is loose, the digital tube will show C2 and flashing,
the machine will work at continuously dehumidification mode.
3.Refrigerant leakage detection: If the refrigerant in refrigeration system leak, the
temperature of evaporator will rise up and become similar to the ambient temperature. When
the compressor operates, the machine will sense the ambient temperature and the
evaporator's temperature every 8 minutes. If the temperature difference between ambient
and evaporator ≤3℃ for 5 times，It might the refrigerant leak in the refrigeration system.
The digital tube will show C8 and flashing.
Remark: When the compressor stop working, such as the compressor stopped due to
the setted humidity reached, the machine won't proceed refrigerant leakage detection.
4. During the machine operates, when detected the DC motor stop running for 15
seconds, the digital tube will show C7 and flashing.
5.When the infrared detection head is damaged(open circuit or Short circuit), the
digital tube will show C3 and flashing.
14. Continuous drainage function
When the machine need continuous drainage, pull out the drain hole plug,use the
drainage tube to connect on the hole. When the machine operates, the water will drain out
via drainage tube, then water tank will not contain the water, then the machine could
continuously work and do not shutdown due to water tank full.
