FEATURES AND FUNCTIONS
AUTOMATIC OPERATION
● COOLING MODEL
Merely press the START/STOP button, and the unit will
begin automatic operation in the Cooling or Dry mode as
appropriate, in accordance with the thermostat setting
and the actual temperature of the room.
● HEAT & COOL MODEL (REVERSE CYCLE)
Merely press the START/STOP button, and the unit will
begin automatic operation in either the Heating, Cooling
or Monitor modes as appropriate, in accordance with the
thermostat setting and the actual temperature of the
room.
ELECTRONIC AIR CLEAN FILTER
Electrical power is used to charge the filter to remove contaminants from the air and to effectively collect dust and
remove odors. It also helps to reduce the bacterial activity.
SLEEP TIMER
● COOLING MODEL
When the SLEEP timer button is pressed 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.
WIRELESS REMOTE CONTROL UNIT
The WIRELESS REMOTE CONTROL UNIT allows convenient
control of air conditioner operation.
OMNI-DIRECTIONAL AIR FLOW
(SWING OPERATION)
Three-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.
REMOVABLE INTAKE FILTER
The indoor unit’s INTAKE FILTER can be removed for easy
cleaning and maintenance.
MILDEW-RESISTANT FILTER
The INTAKE FILTER has been treated to resist mildew growth,
thus allowing cleaner use and easier care.
● HEAT & COOL MODEL (REVERSE CYCLE)
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.
