Helpful information
The air filters and your electric bill. If the air filters become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.
When the air conditioner is used again.
Clean the air filter and install it in the indoor unit.
Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.
Check that the ground wire is connected correctly. It may be connected to the indoor unit side.
Operation Tips
Do not overcool the room.
This is not good for the health and wastes electricity.
Make sure that the doors and windows are shut tight.
Avoid opening doors and windows as much as possible to keep the cool air in the room.
Keep blinds or curtains closed.
Do not let direct sunshine enter the room when the air conditioner is in operation.
Clean the air filter regularly.
Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.
Keep the room temperature uniform.
Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.
Ventilate the room occasionally.
Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

| 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. | Remote control display is faint, or no display at all. |
| 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.Filter sign lamp (LED) is ON.Cleaning the filter, press the Timer button and ◀button of wired remote controller at the same time for 3 sec. | Are the batteries depleted?Are the batteries inserted in the opposite (+) and (-) directions? |
