During Healthy Dehumidification Operation
❏ If you select the dehumidification mode on the OPERATION MODE
SELECTION BUTTON, the product starts to run the dehumidification function. It automatically sets the room temperature and airflow volume to the best
condition for dehumidification, based on the sensed current room temperature. In this case, however, the setting temperature is not displayed on the remote controller and you are not able to control the room temperature either. ❏ During the healthy dehumidification function, the fan speed is automatically set
according to the optimization algorithm responding to the current room
temperature status, so that the room condition is kept healthy and comfortable
even in the very humid season.
Operating Instructions
<For Cooling Model>
The temperature and fan speed are automatically set by the electronic controls based on the
actual room temperature. If you feel hot or cold, press TEMPERATURE SETTING buttons for more cooling or heating effect. You cannot switch the indoor fan speed. It has already been set by the Auto Operation Mode rule.

Troubleshooting Tips! Save time and money!
The air conditioner may be operating abnormally when:
Problem
■ The air conditioner is unplugged.
■ The fuse is blown/circuit breaker is tripped.
■ Power failure.
■ High voltage.
■ Airflow is restricted.
■ The air filter is dirty.
■
The room may have been hot.
■ Cold air is escaping.
■
Check the temperature settings.
■ There might be any heating source in the room.
Air conditioner does not start
Air conditioner does not cool as it should
• Make sure the air conditioner plug is pushed completely into the outlet.
• Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
• If power failure occurs, turn the mode control to OFF. When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.
• If the voltage is unusually very high or low the circuit Breaker will trip.
• Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
• Clean the filter at least every 2 weeks. See the Maintenance and Service section.
• When the air conditioner is first turned on, you need to allow time for the room to cool down.
• Check for open furnace floor registers and cold air returns.
• Make sure they are correct.
• Check and remove such source or turn it off while using the air conditioner.
What To DoPossible Causes
1. Anything abnormal such as burning smell, loud noise etc. happen. Stop the unit and turn the breaker off. Never try to repair by yourself or restart the system in such cases.
2. Main power cord is too hot or damaged.
3. Error code is generated by self diagnosis.
4. Water leaks from indoor unit even if the humidity is low.
5. Any switch, breaker (safety, earth) or fuse fails to work properly
User must carry routine checkup & cleaning to avoid unitʼs poor performance. In case of special situation, the job must be carried out by service person only.
Call the service immediately in the following situations
