This  appliance  is  not  intended  for  use  by  persons  (including  children)  with 

reduced  physical,  sensory  or  mental  capabilities,  or  lack  of  experience  and

  Children should be supervised to ensure that they do not play with the appliance.

 

If you see lightning or hear thunder, there might be a lightning strike. To prevent 

electric shock hazard, turn off the air conditioner by using the remote controller, 

and do not touch the unit or the power plug during thunderstorm.

 

Do not place any other electrical products or household belongings under indoor 

unit or outdoor unit. Dripping condensation from the unit might get them wet, and 

may cause damage or malfunction of your property.

 

Keep clean and tidy around the outdoor unit, and do not place the things around it. 

If it is covered with fallen leaves, there could be an infiltration of small animals or 

insects whose contact with the internal electrical components leads to the product 

malfunction.

 

Do not stand on unstable steps when operating or cleaning the air conditioner. It 

may overturn and can cause the injury.

CAUTION

SAFETY PRECAUTIONS

FEATURES AND FUNCTIONS

Energy saving and Comfortable function

INVERTER

At the start of operation, large amount of power is used to 

bring  the  room  quickly  to  the  desired  temperature. After-

wards, the unit automatically switches to a low power set-
ting for economic and comfortable operation.

ECONOMY OPERATION

When  ECONOMY  operation  mode  is  operated,  the  room 

temperature  will  be  little  higher  than  the  set-temp  under 

cooling mode and lower than set-temp under heating mode. 

Therefore, the ECONOMY mode is able to save more energy 

than other normal mode.

OMNI-DIRECTIONAL AIR FLOW  
(SWING OPERATION)

3-dimensional  control  over  air  direction  swing  is  possible 

through dual use of both an up/down air direction swing and 

right/left air direction swing. Since up/down air direction flaps 

operate automatically according to the operating mode of the 

unit, it is possible to set air direction based on the operating 

mode.

SUPER QUIET OPERATION

When  the  FAN  button  is  used  to  select  QUIET,  the  indoor 

unit begins super quiet operation; the indoor unit’s airflow is 

reduced to produce quieter operation.

AUTO CHANGEOVER

The operation mode (cooling, dry, heating) is switched auto-

matically to maintain the set temperature, and the tempera-

ture is kept constant at all times.

10 °C HEAT OPERATION

The room temperature can be maintained at 10°C so as to pre-

vent the room temperature from falling too far.

Convenient function

PROGRAM TIMER

The program timer allows you to integrate OFF timer and ON 

timer  operations  in  a  single  sequence. The  sequence  can  

involve 1 transition from OFF timer to ON timer, or from ON 

timer to OFF timer, within a 24 hour period.

SLEEP TIMER

When  the  SLEEP  timer  button  is  pressed  during  Heating 

mode,  the  air  conditioner’s  thermostat  setting  is  gradually 

lowered during the period of operation; during cooling or dry 

mode,  the  thermostat  setting  is  gradually  raised  during  the 

period of operation. When the set time is reached, the unit 

automatically turns off.

Clean function

REMOVABLE AIR FILTER

The indoor unit’s air filter can be removed for easy cleaning 

and maintenance.

MILDEW-RESISTANT FILTER

The air filter has been treated to resist mildew growth, thus 

allowing cleaner use and easier care.
