Lamp indication (error) Cause
The "LOW" Operation Indicator Light (Clean Air) blinks. Fan motor disconnected or abnormal. Operation stops.
Pressing the POWER ON/OFF button will reset the error display.
The "Auto" Operation Indicator Light (Clean Air) blinks. Microcomputer Errors.
Remove the power plug, wait for a while, then reinsert the plug and try operating the device again.
The "Humidity Indicator Light (30)" blinks. Temperature/Humidity Sensor Errors.
Remove the power plug, wait for a while, then reinsert the plug and try operating the device again.
Errors Causes Solutions
The air conditioner doesn't start. The power supply is not connected well.
The power plug is not inserted tightly.
There is the malfunction of the power plug or socket.
The fuse is broken.
1. Insert the power plug tightly.
2. Replace the power plug or socket.
3. Ask for the maintenance man to replace the fuse.
Although it was set to COOL mode, there is no cool wind. 1. The room temperature is lower than the set temp.
2. The evaporator frosts.
This is a normal phenomenon. The unit is running in defrosting operation, it will resume running in original operation after defrosting.
Although it was set the DRY mode, there is no cool wind The evaporator frosts. The unit is running in defrosting operation, it will resume running in original oration after defrosting.
The LED displays "E5". The low voltage overcurrent protection. Cut off the power supply, after 10 minutes, turn on the unit, if " still be displays, please inform the maintenance man to maintain.
The LED displays "H8". The water tank gets full. Pour out water in the tank
The LED displays "F1". Malfunction of Ambient temperature sensor. Check if the indoor room temperature sensor is connected properly.
The LED displays "F2". Malfunction of evaporator temperature sensor. Check if the evaporator temperature is connected properly.
