Operation Tips

Do not overcool the room.| Keep blinds or curtains     closed.| Keep the room temperature    uniform.
---|---|---
This is not good for the health and wastes electricity.| Do not let direct sunshine enter the room when the air conditioner is in operation.| Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.
Make sure that the doors and windows are shut tight.| Clean the air filter regularly.| Ventilate the room occasionally.
Avoid opening doors and windows as much as possible to keep the cool air in the room.| Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.| Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

Before you call for service…
Troubleshooting Tips! Save time and money!
Check the following points before requesting repairs or service…. If the malfunction persist, please contact your dealer.

The air conditioner does not operate.| The room has a peculiar odor.| It seems that condensation is leaking from the air conditioner.| Air conditioner does not operate for about 3 minutes when restart.
---|---|---|---
• Have you made a mistake in timer operation?
• Has the fuse blown or has the circuit breaker been tripped?| •  Check that this is not a damp smell exuded by the walls, carpet, furniture or cloth items in the room.| •  Condensation occurs when the airflow from the air conditioner cools the warm room air.| •  This is the protector of the mechanism.

•  Wait about three minutes and operation will begin.

Does not cool or heat effectively.| The air conditioner operation is noisy.| Crack sound is heard.| The air conditioner changes generated airflow during operation.
•  Is the air filter dirty? See air filter cleaning instructions.
•  The room may have been very hot when the room air conditioner was first turned on. Allow time for it to cool down.
•  Has the temperature been set incorrectly?
•  Are the indoor unit’s air inlet or outlet vents obstructed?| •  For a noise that sounds like water flowing.
-This is the sound of freon flowing inside the air conditioner unit.
•  For a noise that sounds like the compressed air releasing into atmosphere.
-This is the sound of the dehumidifying water being processed inside the air conditioning unit.|  

•  This sound is generated by the expansion/ constriction of the front panel, etc. due to changes of temperature.

| •  When the air conditioner reaches the desired temperature, the airflow rate reduces in order to avoid generating cool airflow during heating, or to minimize energy consumption and indoor humidity change during cooling.
– This symptom is normal.
Remote control display is faint, or no display at all.
•  Are the batteries depleted?
•  Are the batteries inserted in the opposite (+) and (-) directions?

NOTE
WATER RESISTANT: The outdoor side of this appliance is WATER RESISTANT.
The indoor side is not water resistant and should not be exposed to excess water.
