FEATURES AND FUNCTIONS
INVERTER
MILDEW-RESISTANT FILTER
The AIR FILTER has been treated to resist mildew growth,
thus allowing cleaner use and easier care.
At the start of operation, a large power is used to bring the
room quickly to the desired temperature. Afterward, the
air conditioner automatically switches to a low power set-
ting for economic and comfortable operation.
SUPER QUIET OPERATION
When the FAN button is used to select QUIET, the indoor
unit begins super-quiet operation; the indoor unit’s airflow
is reduced to produce quieter operation.
WIRELESS REMOTE CONTROLLER
The Wireless Remote Controller allows convenient control
of indoor unit operation.
POLYPHENOL CATECHIN AIR CLEANING FILTER
ECONOMY OPERATION
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.
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.
Note that when the air cleaning filter is installed, the
amount of air produced decreases, causing a slight de-
crease in the indoor unit’s performance.
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.
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.
MINIMUM HEAT OPERATION
The room temperature can be maintained at 50 °F so as to
prevent the room temperature from falling too far.
PROGRAMTIMER
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 pe-
riod.
SLEEPTIMER
When the SLEEP button is pressed during Heating mode,
the indoor unit’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 indoor unit
automatically turns off.
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 INTAKE GRILLE
The indoor unit’s Intake Grille can be removed for easy
cleaning and maintenance.

TROUBLESHOOTING
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the
electrical breaker and consult authorized service personnel.
WARNING!
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 to ensure that power is completely off.
Before requesting service, perform the following checks:
Symptom
Problem

Doesn’t operate immedi-
ately:
If the indoor unit is stopped and then immediately started
again, the compressor will not operate for about 3 minutes, in
order to prevent fuse blowouts.
●
●
NORMAL
FUNCTION
—
Whenever the electrical breaker is turned off then on again the
protection circuit will operate for about 3 minutes, preventing
unit operation during that period.
●
During operation or immediately after stopping the unit, the
sound of water flowing 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 refrigerant flowing).
Noise is heard:
—
● 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 occasion-
al. This sound is produced by the Automatic Defrosting operation.
16
—
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 is
emitted:
● During Cooling or Dry operation, a thin mist may be seen emit-
ted from the indoor unit. This results from the sudden Cooling
of room air by the cool air emitted from the indoor unit, result-
ing 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 Automat-
ic Defrosting operation.
16
Airflow is weak or stops:
● When Heating operation is started, fan speed is temporarily
very low, to allow internal parts to warm up.
—
● During Heating operation, if the room temperature rises above
the thermostat setting, the outdoor unit will stop, and the in-
door unit will operate at very low fan speed. If you wish to
warm the room further, set the thermostat for a higher setting.
● During Heating operation, the indoor unit will temporarily stop
operation (between 7 and 15 minutes) as the Automatic Defrost-
ing mode operates. During Automatic Defrosting operation, the
OPERATION Indicator Lamp will flash.

● During Dry mode, the indoor unit will operate at low speed; in
order to adjust room humidity, the indoor unit’s fan may stop
from time to time. Also, the fan may operate at very low speed
when adjusting room humidity.

OPERATINGTIPS
Operation and Performance
Microcomputer-controlled Automatic Defrosting
Heating Performance
● 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 per-
formance.
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 de-
frosting circuit will operate briefly (for about 7-15 min-
utes).
● This air conditioner operates on the heat-pump princi-
ple, absorbing heat from outdoor air and transferring
that heat to indoor unit. As a result, the operating per-
formance 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.
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (green) will flash.
● After heating operation stops, if frost forms on the out-
door unit, the unit will start Automatic Defrosting op-
eration. At this time, the outdoor unit will automatically
stop after operating for a few minutes.
En-16
OPERATINGTIPS
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, tempo-
rarily turn off the circuit breaker, turn it on and then use
the Remote Controller to resume operation.
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 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 multi-
ple indoor units can be operated simultaneously, but
when two or more indoor units of the same group are
operated simultaneously, the heating and cooling ef-
ficiency will be less than when a single indoor unit is
used alone. Accordingly, when you wish to use more
than one 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.
● Operation can be done in the following different oper-
ating 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 deter-
mined.
● Seasonal and outdoor temperature conditions, the
structure of the rooms and the number of persons
present may also result in differences of operating ef-
ficiency. We recommend that you try various operat-
ing 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.
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 opera-
tion 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.
● If you discover that one or more units delivers a low
level of cooling or heating during simultaneous opera-
tion, we recommend that you stop simultaneous op-
eration of the multiple units.
● 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 be-
gin 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.
