FEATURES AND FUNCTIONS
INVERTER
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 setting for economic and
comfortable operation.
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.
10°C HEAT OPERATION
The room temperature can be maintained at 10°C so as to prevent the room temperature from falling too far.
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.
PROGRAM TIMER
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 period.
SLEEP TIMER
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.
WIRELESS REMOTE CONTROLLER
The Wireless Remote Controller allows convenient control of
indoor unit operation.
SWING OPERATION
The Air ow 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 air ow is reduced
to produce quieter operation.
AIR CLEANING FILTER
Air cleaning lter uses static electricity to clean ne particles and
dust in the air such as tobacco smoke and plant pollen that are
too small to see.
The lter contains catechin, which is highly effective against
various bacteria by suppressing the growth of the bacteria adsorbed to the lter.
Note that when the air cleaning lter is installed, the amount of
air produced decreases, causing a slight decrease in the indoor
unit’s performance.
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

About ECONOMY Operation
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.
• During ECONOMY operation, the thermostat setting automatically changes according to the temperature to avoid Unnecessary cool-
ing and heating for the most economical operation.
● 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.
● 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 multi-type air conditioner, the economy operation mode is only available for the set indoor unit.
While 10°C HEAT OPERATION is in
progress, only Air ow direction set can
be used.

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.
Before requesting service, perform the following checks:
Symptom Problem

NORMAL
FUNCTION
Doesn’t operate immediately:
●
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 protection circuit will operate for about 3 minutes, preventing unit operation
during that period.
—
Noise is heard:
●
During operation or immediately after stopping the unit, the sound of
water 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 refrigerant 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.
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 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.
—
●
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.

Air ow 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 indoor unit will
operate at very low fan speed. If you wish to warm the room further,
set the thermostat for a higher setting.

OPERATING TIPS
If the problem persists after performing these checks, or if you notice burning smells, or the OPERATION Indicator Lamp (Fig. 3 5)
and the TIMER Indicator Lamp (Fig. 3 6) ashes, immediately stop operation, turn off the electrical breaker and consult authorized
service personnel.
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 insuf 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 recirculating air throughout the room, with the result that some time
may be required after rst 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
brie y (for about 7-15 minutes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp will ash, and the DEFROST Indicator Lamp
will light.
● 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.
(However, some type of multi-type air conditioner doesn’t
provide this function.)

OPERATING TIPS
Multi-type Air conditioner
In the case of the indoor unit which 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.
● 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 rst. 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 ash (1 second on, 1 second off) and it would
go into standby mode. Indoor unit (B) would continue to
operate in heating mode.
● 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.
Notice
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 ef ciency 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.
● Seasonal and outdoor temperature conditions, the structure
of the rooms and the number of persons present may also
result in differences of operating ef ciency. We recommend
that you try various operating patterns in order to con 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 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 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 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.
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 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.
