FEATURES AND FUNCTIONS
INVERTER
At the start of operation, large amount of 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.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched auto-
matically to maintain the set temperature, and the temperature
is kept constant at all times.
MIN. (MINIMUM) HEAT OPERATION
The room temperature can be maintained at 50°F (10°C) so as
to prevent the room temperature from falling too far.
ECONOMY OPERATION
When economy operation mode is operated, the room temper-
ature 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.
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
air conditioner’s temperature setting is gradually lowered dur-
ing the period of operation; during cooling mode, the tempera-
ture setting is gradually raised during the period of operation.
When the set time is reached, the unit automatically turns off.
WIRELESS REMOTE CONTROLLER
The Wireless Remote Controller allows convenient control of
air conditioner operation.
SWING OPERATION
The Airflow 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 button is used to select QUIET, the unit begins
super-quiet operation; the indoor unit’s airfl ow is reduced to
produce quieter operation.
POLYPHENOL CATECHIN AIR CLEANING FILTER
The polyphenol catechin air cleaning fi lter uses static electric-
ity to clean the air of fi ne particles and dust such as tobacco
smoke and plant pollen that are too small to see.
The fi lter contains catechin, which is highly effective against
various bacteria by suppressing the growth of the bacteria ad-
sorbed by the fi lter.
Note that when the air cleaning fi lter 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 produce
negative air ions having the effect of deodorizing and can ab-
sorb and remit the peculiar smell at home.
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.
[The additional functions for wired ones]
• Weekly timer

TROUBLESHOOTING
CAUTION
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical breaker or disconnect the
power supply plug, and consult authorized service personnel.
Merely turning off the unit’s power switch will not completely disconnect the unit from the power source. Always be sure to turn off
the electrical breaker or disconnect the power supply plug to ensure that power is completely off.
Before requesting service, perform the following checks:
Symptom Problem

FUNCTION
Doesn’t operate immedi-
ately:
●
If the unit is stopped and then immediately started again, the com-
pressor will not operate for about 3 minutes, in order to prevent fuse
blowouts.
●
Whenever the electrical breaker is turned off than on again or the
power supply plug is disconnected and then reconnected, the protec-
tion circuit will operate for about 3 minutes, preventing unit operation
during that period.
—
Noise is heard:
●
During operation and immediately after stopping the unit, the sound
of water fl owing in the air conditioner’s piping may be heard. Also,
noise may be particularly noticeable for about 2 to 3 minutes after
starting operation (sound of coolant fl owing).
●
During operation, a slight squeaking sound may be heard. This is
the result of minute expansion and contraction of the front panel due
to temperature changes.
—
●
During Heating operation, a sizzling sound may be heard occasional.
This sound is produced by the Automatic Defrosting operation.

Smells:
●
Some smell may be emitted from the indoor unit. This smell is the
result of room smells (furniture, tobacco, etc.) which have been
taken into the indoor unit.
—
Mist or steam are
emitted:
●
During Cooling or Dry operation, a thin mist may be seen emitted
from the indoor unit. This results from the sudden Cooling of room
air by the air emitted from the indoor unit, resulting in condensation
and misting.
—
●
During Heating operation, the outdoor unit’s fan may stop, and
steam may be seen rising from the unit. This is due to Automatic
Defrosting operation.

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
indoors. As a result, the operating performance is reduced
as outdoor air temperature drops. If you feel that insuffi cient
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 recir-
culating air throughout the room, with the result that some
time may be required after fi rst starting the air conditioner
until the room is heated.
Microcomputer-controlled Automatic Defrosting
●
When using the Heating mode under conditions of low out-
door 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
unit is equipped with a Microcomputer-controlled Automatic
Defrosting function. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will operate brief-
ly (for max. 15 minutes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (green) will fl ash.
●
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 oper-
ating for a few minutes.
(However, some type of multi-type air conditioner doesn't
provide this function.)
AUTO Restart
In Event of Power Interruption
●
The air conditioner power has been interrupted by a power
failure. The air conditioner will then restart automatically in
its previous mode when the power is restored.
●
If a power failure occurs during TIMER operation, the timer will
be reset and the 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 fl ash (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 discon-
nect the Power Supply Plug, reconnect it, and then use the
Remote Controller to resume operation.

OPERATING TIPS
Notice
●
During use of the heating mode, the outdoor unit will occa-
sionally 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.
●
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 fi rst. If the in-
door 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 fl ash (1 second on, 1 sec-
ond off) and it would go into standby mode. Indoor unit (B)
would continue to operate in heating mode.
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 simul-
taneously, the heating and cooling effi ciency 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 heat-
ing, it is recommended that they be used in conjunction
with other auxiliary space heaters, as required.
●
Seasonal and outdoor temperature conditions, the struc-
ture of the rooms and the number of persons present may
also result in differences of operating effi ciency. We rec-
ommend that you try various operating patterns in order to
confi rm 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 cannot be done in the following different operat-
ing 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 fl ash (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
●
During use of the heating mode, the top of the indoor unit
may become warm, but this is due to the fact that cool-
ant is circulated through the indoor unit even when it is
stopped; it is not a malfunction.
Multi-type Air conditioner
This indoor unit can be connected to a multi-type outdoor unit. The multi-type air conditioner allows multiple indoor units to be oper-
ated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective output.
