FEATURES AND FUNCTIONS
INVERTER
At the start of operation, a large 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.
COIL DRY OPERATION
The Indoor unit can be dried by pressing the COIL DRY but-
ton on the Remote Control Unit so as to avoid going moldy
and restrain the breed of bacterium.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched au-
tomatically to maintain the set temperature, and the tem-
perature is kept constant at all times.
PROGRAM TIMER
The program timer allows you to integrate OFF timer and
ON timer operations in a single sequence. The sequence can
involve one transition from OFF timer to ON timer, or from
ON timer to OFF timer, within a twenty-four hour period.
SLEEP TIMER
When the SLEEP button is pressed during Heating mode,
the air conditioner’s thermostat setting is gradually lowered
during the period of operation; during cooling mode, the
thermostat setting is gradually raised during the period of
operation. When the set time is reached, the unit automati-
cally turns off.
WIRELESS REMOTE CONTROL UNIT
The Wireless Remote Control Unit allows convenient con-
trol of air conditioner operation.
SWING OPERATION
The Air Flow Direction Louvers swings automatically up and
down so that the air speeds to every nook and corner of
your room.
REMOVABLE OPEN PANEL
The indoor unit’s Open Panel 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.
SUPER QUIET OPERATION
When the FAN CONTROL button is used to select QUIET,
the unit begins super-quiet operation; the indoor unit’s air-
flow is reduced to produce quieter operation.
POLYPHENOL CATECHIN AIR CLEANING FILTER
The polyphenol catechin air cleaning filter uses static elec-
tricity to clean the air of fine particles and dust such as to-
bacco 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 by the filter.
Note that when the air cleaning filter is installed, the amount
of air produced decreases, causing a slight decrease in the
air conditioner's performance.
NEGATIVE AIR IONS DEODORIZING FILTER
It comprises pottery super micro particles, which can pro-
duce negative air ions having the effect of deodorizing and
can absorb and remit the peculiar smell at home.
