• If two or more indoor units are connected, filter cleaning timing for each unit may be different, depending on the filter type.

• The icon will appear when the filter on the main unit is due for cleaning.

• When the filter sign is reset, the cumulative operation time of all units will be reset.

• The icon is scheduled to appear after a certain duration of operation, based on the premise that the indoor units are installed in a space with ordinary air quality. Depending on the air quality, the filter may require more frequent cleaning.

• The cumulative time at which filter needs cleaning depends on the model.

  • This indication is not available for wireless remote controller.

Caution:
Ask authorized people to clean the filter.

Cleaning the filters

• Clean the filters using a vacuum cleaner. If you do not have a vacuum cleaner, tap the filters against a solid object to knock off dirt and dust.
• If the filters are especially dirty, wash them in lukewarm water. Take care to rinse off any detergent thoroughly and allow the filters to dry completely before putting them back into the unit.

1. Pull both the bottom corners of the grille to open the grille, then lift the filter.
   • A. Filter
   • B. Grille

Caution:

• Do not dry the filters in direct sunlight or by using a heat source, such as an electric heater: this may warp them.
• Do not wash the filters in hot water (above 50 °C, 122 °F), as this may warp them.
• Make sure that the air filters are always installed. Operating the unit without air filters can cause malfunction.
• Before you start cleaning, stop the operation and turn OFF the power supply.
• Indoor units are equipped with filters to remove the dust of sucked-in air. Clean the filters using the methods shown in the sketches above.

Cleaning the indoor unit

• Wipe the outside of the unit with a clean, dry, soft cloth.
• Clean off any oil stains or finger marks using a neutral household detergent (such as dishwashing liquid or laundry detergent).

Caution:
Never use gasoline, benzene, thinner, scouring powder or any type of non- neutral detergent, as these substances may damage the unit’s case.

Trouble Shooting

Having trouble?

|

Here is the solution. (Unit is operating normally.)

---|---
The air conditioner does not heat or cool well.| ■ Clean the filter. (Airflow is reduced when the filter is dirty or clogged.)

■ Check the temperature adjustment and adjust the set temperature.

■ Make sure that there is plenty of space around the outdoor unit. Is the indoor unit air intake or outlet blocked?

■ Has a door or window been left open?

When the heating operation starts, warm air does not blow from the indoor unit soon.| ■ Warm air does not blow until the indoor unit has sufficiently warmed

up.

During heating mode, the air conditioner stops before the set room temperature is reached.| ■ When the outdoor temperature is low and the humidity is high, frost

may form on the outdoor unit. If this occurs, the outdoor unit performs a defrosting operation. Normal operation should begin after approximately 10 minutes.

Airflow direction changes during operation or airflow direction cannot be

set.

| ■ During cooling mode, the vanes automatically move to the horizontal

(down) position after 1 hour when the down (horizontal) airflow direction is selected. This is to prevent water from forming and dripping from the vanes.

■ During the heating mode, the vanes automatically move to the horizontal

airflow direction when the airflow temperature is low or during the defrosting mode.

When the airflow direction is changed, the vanes always move up and down past the set position before finally stopping at the position.| ■ When the airflow direction is changed, the vanes move to the set position after detecting the base position.
A flowing water sound or occasional hissing sound is heard.| ■ These sounds can be heard when the refrigerant is flowing in the air conditioner or when the refrigerant flow is changing.
A cracking or creaking sound is heard.| ■ These sounds can be heard when parts rub against each other due to expansion and contraction from temperature changes.
The room has an unpleasant odour.| ■ The indoor unit draws in air that contains gases produced from the walls, carpeting, and furniture as well as odours trapped in clothing, and then blows this air back into the room.
A white mist or vapor is emitted from the indoor unit.| ■ If the indoor temperature and the humidity are high, this condition may

occur when the operation starts.

■ During defrosting mode, cool airflow may blow down and appear like a

mist.

Water or vapor is emitted from the outdoor unit.| ■ During cooling mode, water may form and drip from the cool pipes and

joints.

■ During heating mode, water may form and drip from the heat exchanger.

■ During defrosting mode, water on the heat exchanger evaporates and

water vapour may be emitted.

“  ” appears in the remote controller display.| ■ During central control, “  ” appears in the remote controller display

and air conditioner operation cannot be started or stopped using the remote controller.

When restarting the air conditioner soon after stopping it, it does not operate even though the ON/OFF button is pressed.| ■ Wait approximately 3 minutes. (Operation has stopped to protect the

air conditioner.)

Air conditioner operates without the ON/OFF button being pressed.| ■ Is the on-timer set?

Press the ON/OFF button to stop the operation.

■ Is the air conditioner connected to a central remote controller?

Consult the concerned people who control the air conditioner.

■ Does “  ” appear in the remote controller display?

Consult the concerned people who control the air conditioner.

■ Has the auto-recovery feature from power failures been set?

Press the ON/OFF button to stop the operation.

Air conditioner stops without the ON/OFF button being pressed.| ■ Is the off- timer set?

Press the ON/OFF button to restart the operation.

■ Is the air conditioner connected to a central remote controller?

Consult the concerned people who control the air conditioner.

■ Does “  ” appear in the remote controller display?

Consult the concerned people who control the air conditioner.

Remote controller timer operation cannot be set.| ■ Are timer settings invalid?

If the timer can be set or appears in the remote controller display.

“Please Wait” appears in the remote controller display.| ■ The initial settings are being performed. Wait approximately 3 minutes.
An error code appears in the remote controller display.| ■ The protection devices have operated to protect the air conditioner.

■ Do not attempt to repair this equipment by yourself.

Turn off the power switch immediately and consult your dealer. Be sure to provide the dealer with the model name and information that appeared in the remote controller display.

Having trouble?

|

Here is the solution. (Unit is operating normally.)

---|---
Draining water or motor rotation sound is heard.| ■ When the cooling operation stops, the drain pump operates and then stops.

Wait approximately 3 minutes.

Noise is louder than specifications.| ■ The indoor operation sound level is affected by the acoustics of the particular room as shown in the following table and will be higher than the noise specification, which was measured in an anechoic room.
Nothing appears in the wireless remote controller display, the display is faint, or signals are not received by the indoor unit unless the remote controller is closed.| ■ The batteries are low.

Replace the batteries and press the Reset button.

■ If nothing appears even after the batteries are replaced, make sure

that the batteries are installed in the correct directions (+, –).

After battery installation/replacement of the remote controller, part of the function cannot be used.| ■ Please check that the clock setting is completed. If the clock setting is not done, please complete it.
The operation lamp near the receiver for the wireless remote controller on the indoor unit is blinking.| ■ The self-diagnosis function has operated to protect the air conditioner.

■ Do not attempt to repair this equipment by yourself.

Turn off the power switch immediately and consult your dealer. Be sure to provide the dealer with the model name.

The indoor unit which is not operating becomes warm and a sound, similar to water flowing, is heard from the unit.| ■ A small amount of refrigerant continues to flow into the indoor unit even though it is not operating.
