Troubleshooting procedures

1 • Check the items to check first time.

2 • Check the self-diagnostic mode and action method.

3 • Check in detail the troubled parts according to the sequence of "trouble shooting by the phenomena".

1. Is proper the power voltage?The power voltage shall be of 198V-264V 50Hz.

2. Is the cable connected correctly between the indoor and outdoor unit?The indoor and outdoor units shall be connected with 8 wires including the grounding.Check whether the wires of indoor and outdoor units are connected with the correct wire no. and terminal board no.

3. The phenomena in the following table is not related to the fault of air conditioner.

- Heating operationThe compressor does not operated even though the settemperature is set higher than the indoor temperature.

- Cooling operation The compressor does not operated even though the settemperature is set lower than the indoor temperature.

- Fan speed is not adjusted during the auto, dry, turbo andlong operation.

- The temperature is not adjusted during the auto, dry, turboand long and fan operation.

- The compressor repeats the stop and start with the inter-val of several minutes during dry.

- During the heating operation, the lamp on "deice" is on atthe control panel and the compressor operates.

- During the heating, the outdoor unit fan motor repeatsstart/stop or even the compressor repeats the start andstop.

- During the heating, the compressor and outdoor unit fanmotor operate but indoor unit fan motor does not operate.

Phenomena Description

- The operation of compressor is delayed for 3 minutes forthe protection of compressor when it is off and on again.

- The compressor operates normally after 3 minutes even thelnitial power is on.

- The fan speed is automatically adjusted during the auto,dry, turbo and long operation.

- The set temperature is automatically set during the auto,dry and long operation.

- The wind blow operation is the mode to circulate the indoorair.

- At the dry operation, the set temperature and the indoortemperature are compared to adjust the compressorstart/stop time in order to dehumidify.

- The deice operation is being performed in order to melt thefrost by outdoor unit and its maximum time is 9 minutes.

- It is the function to prevent the overheating of the indoorevaporator, where the temperature of indoor unit heatexchanger reaches 52°C, the normal operation is done.

- This is the function to prevent the cooling air incoming tothe indoor, where the temperature of indoor evaporatorreaches 27°C, the indoor fan motor operates.
