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. Afterward,
the air conditioner automatically switches to a low power setting 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. Therefore, the ECONOMY mode is able to save more
energy than other normal mode.
SWING OPERATION
The Airflow Direction Louvers swings automatically up and
down so that the air speeds to every nook and corner of your
room.
AUTO CHANGEOVER
The operation mode (cooling and dry) is switched automatically to maintain the set temperature, and the temperature is
kept constant at all times.
SUPER QUIET OPERATION
The indoor unit’s air ow is reduced to produce quieter operation.
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 button is pressed during cooling mode, the
temperature setting is gradually raised during the period of
operation. When the set time is reached, the indoor unit automatically turns off.
Clean function
REMOVABLE INTAKE GRILLE
The indoor unit’s Intake Grille 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.
POLYPHENOL CATECHIN AIR CLEANING FILTER
The Polyphenol Catechin Air Cleaning lter uses static electricity to clean ne particles and dust in the air such as tobacco
smoke and plant pollen that are too small to see. The filter
contains catechin, which is highly effective against various
bacteria by suppressing the growth of the bacteria adsorbed to
the lter.
Note that when the Air Cleaning Filter is installed, the amount
of air produced decreases, causing a slight decrease in the
indoor unit’s performance.
NEGATIVE AIR IONS DEODORIZING FILTER
It comprises pottery super micro particles which can produce
negative air ions having the effect of deodorizing and can absorb and remit the peculiar smell at home.
