If the machine is under dehumidifying or refrigerating,fetching out water tank
or switching OFF and then switching ON, interval time should reach 3 minutes,
and then machine will start dehumidifying.
6. Low&High temperature protection function:
When temperature and humdity sensor test Room temperature≤0℃ or ≥40℃
and the sensor's NTC disconnection or short circuit, compressor and fan motor
haven't output, buzzer warning all the time and there is no reflection when
pressing any button, and it just will be effective after switch ON anew.
7. Failures Of Humidity&Temperature Sensor:
When the connect wire of humidity and temperature sensor breaks off, the
symbol of continuous dehumidification "Cont" will wink. It doesn't work
when pressing humidity setting button, but other function is well.
The appliance comes into continuous dehumidifying mode.
8. Refrigerent leakage test function:
The compressor will test the temperature of temperature and humdity sensor
and NTC of evaporator's copper tube in every 8 minutes; If compressor test the
temperature different value is ≤3℃ between temperature and humidity sensor
and evaporator's NTC successive 2 times, then it indicates abnormal, digit tube
blink (lightening 1s and extinguishing 1s)
