Airflow Direction Procedure

Airflow Direction Control

The airflow direction can be adjusted as desired by using the remote controller. This is effective when you want to cool yourself directly, such as after taking a bath.

Illustration of a car air conditioner with airflow direction arrow (no text or symbols)

1 Press the Start/Stop Button. (Confirm the unit on operation.)

2 Press the Airflow Direction Control Button and the vertical louvers swing up and down automatically.

3 Press again the Airflow Direction Control Button to set the vertical louver at the desired airflow direction.

Horizontal Airflow Direction Control (Optional)

- Adjust the horizontal airflow direction by manually moving the horizontal airflow direction louver by hand.

Caution

• Always use the remote controller to adjust the airflow direction. Manually moving the vertical airflow direction louver by hand could cause operation errors.
- When air conditioner operation is stopped, the vertical airflow direction louver will close the air outlet vent of room air conditioner.

Forced Operation

Operation procedures when the remote control can't be used.

The operation will be started if the power button is pressed.

If you want to stop operation, re-press the button.

Setting Temperature	22 C	22 C	23 C	24 C

Test operation

During the TEST OPERATION, the unit operates in cooling mode at high speed fan, regardless of room temperature and resets in 18 minutes.

During test operation, if remote controller signal is received, the unit operates as remote controller sets.

If you want to use this operation, open the front panel upward and Press the power button let it be pressed for about 3 seconds.

If you want to stop the operation, re-press the button.

Auto restart

In case the power comes on again after a power failure, Auto Restarting Operation is the function to operate procedures automatically to the previous operating conditions.

So there is no need of activating this function by pressing any key or button.

In the initial mode, the fan operates at a low speed and the compressor starts 2.5\~3 minutes later.

As the compressor starts, the fan speed also resumes its previous setting mode.

Additionally, in order to cancel auto restart operation press power button let it be pressed for about 6 seconds. To operate auto restart operation again, press power button for about 6 seconds as well.

Helpful information

Fan speed and cooling capacity.

The cooling capacity indicated in the specification is the value when the fan speed is set to high, and the capacity will be lower at low or medium fan speed.

High fan speed is recommended when you wish to cool the room quickly.

Outdoor Unit

□ Never use any of the followings:

• Water hotter than 40°C
Could cause deformation and/or discoloration.
- Volatile substances
Could damage the surfaces of the air conditioner.

Benzene Panda Gasoline

1 Lift the front access panel and pull the filter tab slightly forward to remove the filter.
2 Clean the filter with a vacuum or warm, soapy water.

- If dirt is conspicuous, wash with a solution of detergent in lukewarm water.

- If hot water (40°C or more) is used, it may be deformed.

3 After washing with water, dry well in the shade.
4 Re-install the air filter.

The heat exchanger coils and panel vents of the outdoor unit should be checked regularly. If clogged with dirt or soot, the heat exchanger and panel vents may be professionally steam cleaned.

NOTE:

Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs.

When the air conditioner is not going to be used for

When air conditioner is not going to be used for a long time.

Turn off the circuit breaker, and disconnect the plug.

CAUTION

Turn off the circuit breaker when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a fire.

Remove the batteries from the remote control.

When the air conditioner is to be used again.

Clean the air filter and install it in the indoor unit. (Refer to page 13 for cleaning filters.)

Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.

Operation Tips

Do not overcool the room.

This is not good for the health and wastes electricity.

Keep blinds or curtains closed.

Do not let direct sunshine enter the room when the air conditioner is in operation.

Keep the room temperature uniform.

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.

Avoid opening doors and windows as much as possible to keep the cool air in the room.

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.

Ventilate the room occasionally.

Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

Troubleshooting Tips! Save time and money!

Check the following points before requesting repairs or service.... If the fault persists, please contact your dealer or service center.

Case Explanation See page
The air conditioner does not operate.	Have you made a mistake in timer operation?
	Has the fuse blown or has the circuit breaker been tripped?	-
The room has a peculiar odor.	Check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room.	-
It seems that condensation is leaking from the air conditioner.	Condensation occurs when the airflow from the air conditioner cools the warm room air.	-
Air conditioner does not operate for about 3 minutes when restarted.	This is the protector of the mechanism.Wait about three minutes and operation will begin.	-
Does not cool or heat effectively.	Is the air filter dirty? See air filter cleaning instructions.	13
	Has the temperature been set incorrectly?	7
	Are the indoor unit's air inlet or outlet vents obstructed?	-
The air conditioner operation is noisy.	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.	-
Remote control display is faint, or no display at all.	Are the batteries depleted?Are the batteries inserted in the opposite (+) and (-) directions?	4
Crack sound is heard.	This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature.	-

NOTE

WATER RESISTANT: The outdoor side of this appliance is WATER RESISTANT.
