SAFETY PRECAUTIONS
The following safety precautions must be taken when using your air
conditioner.
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 the
malfunction of the air conditioner.
Operation of air conditioner
Explanation
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 a
delay of 3 minutes, the indoor fan is adjusted automatically with
reference 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.
Compressor stops operation intermittently in DRY mode.
Compressor operation is automatically controlled in DRY mode
depending 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, the
compressor continues operation for up to 10 minutes(maximum)
until the deice is completed.
Timer indicator lamp lights up and the air conditioner does
not 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 HEAT
mode.
The compressor and indoor fan stop intermittently if room
temperature exceeds a setting temperature in order to protect
the 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 exterior
ice 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 DRY
mode, 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 frozen
depending on the inside/outside air temperature.
