Fresh Air In During Sleep Mode Operation
(Page 23)
• By configuring Fresh Air In During Sleep Mode, the air conditioning operates the fresh air in during sleep mode
operation (while cooling or dehumidifying) when the outside air temperature is lower than room temperature.
• If “Sleep Timer” operation of the air purifier is performed while the Fresh Air In During Sleep Mode is configured,
ventilating operation that takes the air from the outside into the room air conditioning fan when the outside air temperature
is lower than room temperature.
• If the room temperature decreases about 2°C below than configured temperature while fresh air in operating, the
fresh air in operation will be stopped.
• The fan speed cannot be adjusted in fresh air in during sleep mode.
• If the heating operation is performed while the Fresh Air In During Sleep Mode is configured, Fresh Air In During Sleep
Mode operation will be canceled, however, when the heating operation is stopped, the mode returns to Fresh Air In
During Sleep Mode settings.
• If the fresh air in/exhaust operation is performed while the Fresh Air In During Sleep Mode is configured, Fresh Air In
During Sleep Mode operation will be canceled, however, when the fresh air in/exhaust operation is stopped, the mode
returns to Fresh Air In During Sleep Mode settings.
• The fresh air in does not operate depending on the room temperature/outside air temperature.
Installing the Device when the Two Way Air Exchange Cannot Operate
■ If the installation work specified for the embedded ducting cannot be vented the two way air exchange hose
outside the room, please select “Only Exhaust” or “Prohibit Two Way Air Exchange”.
When selecting “Prohibit Two Way Air Exchange”
• When the two way air exchange hose cannot be vented
outside of the room directly (installation work specified for
the embedded ducting).
• When there is a source of odor, smoke, or oily smoke in the
vicinity of the exit of the two way air exchange hose, even if
the installation work directly vents the two way air exchange
hose outside the room.
When selecting “Only Exhaust” (only exhaust
operation can be operated)
• When there is some space to vend the two way air exchange
hose between the internal and external walls, which leads
outside the room, even if the two way air exchange hose
cannot be vented outside of the room directly (conventional
construction methods).
• There is a restriction to the length of the two way air
exchange hose (maximum length is 3m).

Automatic Two Way Air Exchange Operation
• The Dirt Sensor detects cigarette smoke, sprays (pesticides), alcohol, etc.
• The Dirt Sensor may also respond to sudden temperature changes when the cooling/heating operation starts and
sudden changes in airflow when doors open and close.
• The automatic two way air exchange can be configured for two weeks at one time. The
(AUTOMATIC TWO WAY
AIR EXCHANGE) is configured for two weeks after it is set with the remote controller.
• Even the air in the room is dirty after the automatic two way air exchange operation has been configured, the exhaust
operation does not perform for 5 minutes.
• In the case the automatic two way air exchange operation performs during the air conditioning operation, the exhaust
or fresh air in operates in addition to the air conditioning.
• Once the dirt sensor detects the dirt and starts exhaust operation, even you open the window after that the exhaust
operates for at least 20 minutes and then operates the fresh air in.
• The two way air exchange operation does not perform depending on the room temperature/outside air temperature.
Changing the Sensitivity of the Dirt Sensor
■ There are 7 levels of sensitivity
1
Press the button while the operation is stopped.
(Please operate either the fresh air in or the exhaust. Select the fan speed “HI”, “MED” or

Please stop the operation with the button.
Self Clean Operation
(Page 19)
• By setting Self Clean operation, it automatically starts self clean operation after stopping the cooling and dehumidifying
operations. First, wash the odor components attached to the indoor heat exchanger due to the “FAN” operation (combined
with the exhaust). Next, “HEATING” (combined with the exhaust), “ONLY EXHAUST” and “FAN” operation (combined
with the exhaust) are performed to suppress the outbreak of mold in the indoor unit.
• If the outside air temperature is low, the cooling and dehumidifying may not operate.
• If the ON-TIMER has been configured, the Self Clean operation does not perform two hours before the configured
time.
• If the operation is stopped in the following conditions, the Self Clean operation does not perform. (Heating and Air
purifying operations, stopped by pressing OFF-TIMER or SLEEP TIMER.)
Timer Settings
• If the remote controller never receive the signal when timer is set, it does not start to operate even when reaching the
set time. Please confirm the timer setting by the “beep” sound and the “Timer” lamp on the indoor unit.
• When the dehumidifying is operated while the timer is configured, the timer settings will disappear from the LCD, but
the setting is not canceled. When the dehumidifying operation is stopped, the timer settings will display again.
