The following safety precautions must be taken when using your air conditioner.

SAFETY PRECAUTIONS

1. Warning: Prior to repair, disconnect the power cord.

2. Use proper parts: use only exact replacement parts. (Also, we recommend replacing parts rather

than repairing them.)

3. Use the proper tools: use the proper tools and test equipment, and know how to use them. Using

defective tools or test equipment may cause problems later-intermittent contact, for example.

4. Power cord: prior to repair, check the power cord and replace it if necessary.

5. Avoid using an extension cord, and avoid tapping into a power cord. This practice may result in

malfunction or fire.

6. After completing repairs and reassembly, check the insulation resistance.

Procedure: prior to applying power, measure the resistance between the power cord and the ground

terminal. The resistance must be greater than 30 megohms.

7. Make sure that the grounds are adequate.

8. Make sure that the installation conditions are satisfactory. Relocate the unit if necessary.

9. Keep children away from the unit while it is being repaired.

10. Be sure to clean the unit and its surrounding area.

TROUBLE SHOOTING Items to be checked first

1. Is the voltage of the power correct? The input voltage shall be rating voltage ±10%. The air conditioner may not operate properly if the voltage is out of this range.

2. Is the link cable connecting the indoor unit and the outdoor unit linked properly? Please refer to the wiring diagram Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.

3. When a problem occurs due to the contents illustrated in the table below, it is symptom not related to themalfunction of the air conditioner.

Operation of air conditioner

In COOL operation mode, the compressor does not operate at a room temperature higher than the setting temperature that the indoor fan should operate.In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that indoor fan should operate.

It happens after a delay of 3 minutes when the compressor is reoperated. The same phenomenon occurs when a power is on.As a phenomenon that the compressor is reoperated after adelay of 3 minutes, the indoor fan is adjusted automatically withreference to a temperature of the air blow.

Fan speed setting is not allowed in AUTO or DRY mode. The speed of the indoor fan is set to low in DRY mode.Fan speed of 3 steps is selected automatically in AUTO mode.

Explanation

Compressor stops operation intermittently in DRY mode. Compressor operation is automatically controlled in DRY modedepending on the room temperature and humidity.

Compressor of the outdoor unit is operating although it is turned off in HEAT mode.

When the unit is turned off while de-ice is activated, thecompressor continues operation for up to 10 minutes(maximum)until the deice is completed.

Timer indicator lamp lights up and the air conditioner doesnot operate.

Timer is being activated and the unit is in ready mode.The unit operates normally if the timer operation is cancelled.

The compressor and indoor fan stop intermittently in HEATmode.

The compressor and indoor fan stop intermittently if room temperature exceeds a setting temperature in order to protectthe compressor from overheated air in HEAT mode.

Indoor fan and outdoor fan stop intermittently in HEAT mode.The compressor operates in a reverse cycle to remove exteriorice in HEAT mode, and indoor fan and outdoor fan do not operate intermittently for within 20% of the total heat operation.

The compressor stops intermittently in COOL mode or DRYmode, and fan speed of the indoor unit decreases.

The compressor stops intermittently or the fan speed of the indoor unit decreases to prevent inside/outside air frozendepending on the inside/outside air temperature.
