: Indicates a part which must be grounded.

Warning:

• There appliances are not accessible to the general public.
• The unit must not be installed by the user. Ask the dealer or an authorized company to install the unit. If the unit is installed improperly, water leakage, electric shock or fire  may result.
• Do not alter the unit. It may cause fire, electric shock, injury or water leakage.
• Do not stand on, or place any items on the unit.
• Do not splash water over the unit and do not touch the unit with wet hands. An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance where it will be exposed to the air discharged from the unit. Incomplete combustion may result.
• Do not remove the front panel or the fan guard from the outdoor unit when it is running.
• When you notice exceptionally abnormal noise or vibration, stop operation, turn off the power switch, and contact your dealer.
• Never insert fingers, sticks etc. into the intakes or outlets.
• If you detect odd smells, stop using the unit, turn off the power switch and consult your dealer. Otherwise, a breakdown, electric shock or fire may result.
• This air conditioner is NOT intended for use by children or infirm persons without supervision.
• If the refrigeration gas blows out or leaks, stop the operation of the air conditioner, thoroughly ventilate the room, and contact your dealer.
• This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for commercial use by lay persons.
• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
• When installing or relocating, or servicing the air conditioner, use only the specified refrigerant written on outdoor unit to charge the refrigerant lines. Do not mix it with any other refrigerant and do not allow air to remain in the lines. If air is mixed with the refrigerant, then it can be the cause of abnormal high pressure in the refrigerant line, and may result in an explosion and other hazards. The use of any refrigerant other than that specified for the system will cause mechanical failure or system malfunction or unit breakdown. In the worst case, this could lead to a serious impediment to securing product safety.
• This unit should be installed in rooms which exceed the floor space specified in outdoor unit installation manual. Refer to outdoor unit installation manual.

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.
  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), 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 suckedin air. Clean the filters using the methods shown in the sketches above.
• Cleaning the air cleaning fi lter (option)

Every 3 months:

• Remove dirt by a vacuum cleaner.
  When dirt cannot be removed by vacuum cleaning:

• Soak the fi lter and its frame in lukewarm water before rinsing it.

• After washing, dry it well in shade. Install all tabs of the air fi lter.

Every year:

• Replace it with a new air cleaning fi lter for best performance.

3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license  applies only to those patent claims licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of their Contribution(s) with  the Work to which such Contribution(s) was submitted. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that  the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License  for that Work shall terminate as of the date such litigation is filed.

The contents of the NOTICE file are for informational purposes only and do not modify the License. You may add Your own attribution notices within Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot be construed as modifying the License.
   You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License.

9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License. However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability.
