• To return to the previous screen ………………….. [RETURN] button

When the is displayed on the Main display in the Full mode, the system is centrally controlled and the filter sign cannot be reset.

­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.

► 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.
  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.
  Caution:

• Before you start cleaning, stop 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 following sketches.

► Filter removal

  Caution:

• In removing the filter, precautions must be taken to protect your eyes from dust. Also, if you have to climb up on a stool to do the job, be careful not to fall.
• When the filter is removed, do not touch the metallic parts inside the indoor unit, otherwise injury may result.

If this occurs, the outdoor unit performs a defrosting operation. Normal operation should begin after approximately 10 minutes.
Airflow up/down direction changes during operation or airflow up/down direction cannot be set.| n During cooling mode, the vanes automatically move to the horizontal (down) position after 1 hour when the down (horizontal) airflow up/ down direction is selected. This is to prevent water from forming and dripping from the vanes.
n During heating mode, the vanes automatically move to the horizontal airflow up/down direction when the airflow temperature is low or during defrosting mode.
When the airflow up/down direction is changed, the vanes always move up and down past the set position before finally stopping at the position.| n When the airflow up/down 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.| n These sounds can be heard when refrigerant is flowing in the air conditioner or when the refrigerant flow is changing.
A cracking or creaking sound is heard.| n These sounds can be heard when parts rub against each due to expansion and contraction from temperature changes.

A white mist or vapor is emitted from the indoor unit.| n If the indoor temperature and the humidity are high, this condition may occur when operation starts.
n During defrosting mode, cool airflow may blow down and appear like a mist.
Water or vapor is emitted from the outdoor unit.| n During cooling mode, water may form and drip from the cool pipes and joints.
n During heating mode, water may form and drip from the heat exchanger.
n During defrosting mode, water on the heat exchanger evaporates and water vapor may be emitted.
