FEATURES AND FUNCTIONSFEATURES 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. Afterwards,
the unit automatically switches to a low power setting for economic and comfortable operation.
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.
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.
AUTO CHANGEOVER
■ Clean function
REMOVABLE INTAKE GRILLE
The indoor unit’s intake grille 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.
POLYPHENOL CATECHIN AIR CLEANING FILTER
The polyphenol catechin air cleaning fi lter uses static electric-
ity to clean fi ne 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 fi lter. Note that when the air cleaning fi lter 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 ab-
sorb and remit the peculiar smell at home.
■ Remote controller
The operation mode (cooling, dry, heating) is switched automatically to maintain the set temperature, and the temperature
is kept constant at all times.
10°C HEAT OPERATION
The room temperature can be maintained at 10°C so as to
prevent the room temperature from falling too far.
■ Convenient function
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 timer button is pressed during heating mode,
the air conditioner’s thermostat setting is gradually lowered during the period of operation; during cooling or dry mode, the thermostat 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.
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
• Temperature set back timer
And you can use both wired and wireless remote controller si-
multaneously. (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 fl ash.

TROUBLESHOOTING
WARNING!
Before requesting service, perform the following checks:
NORMAL
FUNCTION
Doesn’t operate immediately:
Noise is heard:
Smells:
Mist or steam is emitted:
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical
breaker 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 to ensure that power is completely off.
Symptom
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.
Whenever the electrical breaker is turned off then on again the pro-
●
tection 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 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.
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.
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 cool air emitted from the indoor unit, resulting in condensation and misting.

Airfl ow is weak or stops:
Water is produced from the
outdoor unit:
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.
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 indoor 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 opera-
●
tion (between 7 and 15 minutes) as the Automatic Defrosting mode
operates. During Automatic Defrosting operation, the OPERATION
Indicator Lamp will fl ash.
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.
During SUPER QUIET operation, the fan will operate at very low speed.
●
In the monitor of AUTO operation, the fan will operate at very low
●
speed.
In case of Multi-type unit, if multiple units are operated in different op-
●
eration modes as shown below, the units operated afterward will stop
and the OPERATION indicator lamp (green) will fl ash.

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 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
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 briefl y (for about 7-15 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 operating for a few minutes.
En-17
OPERATING TIPS
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.
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 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 heating, 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
If a power interruption occurs during TIMER operation, the tim-
●
er 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 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 turn off
the circuit breaker, turn it on and then use the Remote Controller to resume operation.
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.
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.
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.
