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.
HUMAN SENSOR (ENERGY SAVING)
When the sensor detects that there is no one in the room, it
automatically reduces the operating power. It saves you money by reducing the power consumed.
ECONOMY OPERATION
When ECONOMY operation mode is operated, the room temperature 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.
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, dry, heating) is switched automatically to maintain the set temperature, and the temperature
is kept constant at all times.
SUPER QUIET OPERATION
The indoor unit’s airflow is reduced to produce quieter operation.
10 °C HEAT OPERATION
The room temperature can be maintained at 10 °C so as to
prevent the room temperature from falling too far.
OUTDOOR UNIT LOW NOISE OPERATION
OUTDOOR UNIT LOW NOISE operation mode reduces the
noise level of the outdoor unit by suppressing the fan speed
and the rotation number of the compressor. It is effective when
the surrounding area is quiet, such as in the night.
*This function cannot be used for the Multi-type air conditioner.
■ Convenient function
WEEKLY TIMER
The combination of the temperature setting and the timer function, which you can choose any day between Monday and
Sunday, can be set freely.
You can set up to four ON Timers or OFF Timers in one day.
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 Heating mode, the
indoor unit’s temperature setting is gradually lowered during the
period of operation; 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.
POWERFUL OPERATION
The product will operate at maximum power, which is convenient
when you want to quickly cool down or warm up the room.
■ Clean function
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 filter uses static electricity
to clean fine 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 filter.
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.
■ Remote controller
WIRELESS REMOTE CONTROLLER
The Wireless Remote Controller allows convenient control of indoor unit operation.
WIRED REMOTE CONTROLLER (OPTION)
The optional wired remote controller can be used. When you
use remote controller, there are following different points as
compared with using wireless remote controller.
And you can use both wired and wireless remote controller simultaneously. (But function is limited)
When the restricted functions on the remote controller are used,
beeping sound will be heard, OPERATION, TIMER and the 3rd
lamp of the indoor unit will flash.

About ECONOMY Operation
● When ECONOMY operation mode is operated, the room temperature 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.
● In case of single-type air conditioner, at the maximum output, ECONOMY operation is approximately 70% of normal air conditioner operation for cooling and heating.
● In case of multi-type air conditioner, the ECONOMY operation mode is only available for the set indoor unit.
● If the room is not cooled (or heated) well during ECONOMY operation, select normal operation.
● During the monitor period in the AUTO mode, the air conditioner operation will not change to ECONOMY operation even if
ECONOMY operation is selected by pressing the ECONOMY operation button.

OPERATING TIPS
Operation and Performance
Heating Performance
● This air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat
to indoor unit. As a result, the operating performance is
reduced as outdoor air temperature drops. If you feel that
insufficient heating performance is being produced, we
recommend you use this air conditioner in conjunction with
another kind of heating appliance.
● Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some
time may be required after first starting the air conditioner
until the room is heated.
Microcomputer-controlled Automatic Defrosting
● When using the Heating mode under conditions of low outdoor temperature and high humidity, frost may form on the
outdoor unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this
air conditioner is equipped with a Microcomputer-controlled
Automatic Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will
operate briefly (Max. 15 minutes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (green) will flash.
● After heating operation stops, if frost forms on the outdoor
unit, the unit will start Automatic Defrosting operation. At
this time, the outdoor unit will automatically stop after operating for a few minutes.
AUTO Restart
In Event of Power Interruption
● The power supply to the air conditioner is stopped by a
power interruption. The air conditioner will then restart automatically in its previous mode when the power is restored.
● If a power interruption occurs during TIMER operation, the timer will be reset and the indoor unit will begin (or stop) operation
at the new time setting. In the event that this kind of timer fault
occurs, the TIMER Indicator Lamp will flash (see page 3.).
● Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the air
conditioner to malfunction. In this event, temporarily turn off
the circuit breaker, turn it on and then use the Remote Controller to resume operation.

OPERATING TIPS
Multi-type Air conditioner
This indoor unit can be connected to a multi-type outdoor unit depending on model. The multi-type air conditioner allows multiple indoor units to be operated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective
output.
Simultaneous Use of Multiple Units
● When using a multi-type air conditioner, the multiple indoor
units can be operated simultaneously, but when two or
more indoor units of the same group are operated simultaneously, the heating and cooling efficiency will be less
than when a single indoor unit is used alone. Accordingly,
when you wish to use more than 1 indoor unit for cooling
at the same time, the use should be concentrated at night
and other times when less output is required. In the same
way, when multiple units are used simultaneously for heating, it is recommended that they be used in conjunction
with other auxiliary space heaters, as required.
● Seasonal and outdoor temperature conditions, the structure of the rooms and the number of persons present may
also result in differences of operating efficiency. We recommend that you try various operating patterns in order to
confirm the level of heating and cooling output provided by
your units, and use the units in the way that best matches
your family’s lifestyle.
● If you discover that one or more units delivers a low level
of cooling or heating during simultaneous operation, we
recommend that you stop simultaneous operation of the
multiple units.
● Operation can be done in the following different operating
modes.
Cooling mode and Dry mode
Cooling mode and Fan mode
Dry mode and fan mode
● The operating mode (heating mode or cooling (dry) mode)
of the outdoor unit will be determined by the operating
mode of the indoor unit that was operated first. If the indoor unit was started in fan mode, the operating mode of
the outdoor unit will not be determined.
For example, if indoor unit (A) was started in fan mode
and then indoor unit (B) was then operated in heating
mode, indoor unit (A) would temporarily start operation
in fan mode but when indoor unit (B) started operating in
heating mode, the OPERATION indicator lamp (green) for
indoor unit (A) would begin to flash (1 second on, 1 second off) and it would go into standby mode. Indoor unit (B)
would continue to operate in heating mode.
● Operation cannot be done in the following different operating modes.
If the indoor unit is instructed to do an operating mode that
it cannot perform, the OPERATION indicator lamp (green)
on the indoor unit will flash (1 second on, 1 second off)
and the unit will go into the standby mode.
Heating mode and cooling mode (or dry mode)
Heating mode and fan mode
Notice
● During use of the heating mode, the outdoor unit will occasionally commence the defrost operation for brief periods.
During the defrosting operation, if the user sets the indoor
unit for heating again, the defrosting mode will continue,
and the heating operation will begin after completion of
defrosting, with the result that some time may be required
before warm air is emitted.
● During use of the heating mode, the top of the indoor unit
may become warm, but this is due to the fact that coolant is circulated through the indoor unit even when it is
stopped; it is not a malfunction.
Temperature and Humidity Range
Permissible ranges of temperature and humidity are as follows:
Cooling/Dry
Operation
Indoor temperature
About 18 °C to 32 °C
Indoor humidity
Below approximately 80%.
If the air conditioner is used continuously for
many hours, water may condense on the surface and drip.
Heating
Indoor temperature
About 16 °C to 30 °C
If the unit is used under higher temperature conditions than those noted here, the automatic protection circuit may operate, interrupting the operation.
If the unit is used under lower temperature conditions than those noted here, the heat exchanger may freeze, causing water leakage
or other malfunction.
● Do not use the air conditioner for any purpose other than room cooling/dry, room heating or fan.
