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. Afterwards, 
the unit automatically switches to a low power setting for eco-
nomic and comfortable operation.

ECONOMY OPERATION

When ECONOMY operation mode is operated, the room tem-
perature 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 

fl

 aps operate automatically according to the operating mode of 

the unit, it is possible to set air direction based on the operat-
ing 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 re-
duced to produce quieter operation.

AUTO CHANGEOVER

The operation mode (cooling, dry, heating) is switched auto-
matically to maintain the set temperature, and the temperature 
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 in-
volve 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 pe-riod 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 au-
tomatically turns off.

■ 

Clean function

REMOVABLE INTAKE GRILLE

The indoor unit’s intake grille can be removed for easy clean-
ing and maintenance.

MILDEW-RESISTANT FILTER

The AIR FILTER has been treated to resist mildew growth, 
thus allowing cleaner use and easier care.

■

conditioner operation.
