„ About batteries
• When replacing the batteries, use batteries of the
same type, and replace the two old batteries together.
• When the system is not used for a long time, take the
batteries out.
• We recommend replacing once a year, although if the
remote controller display begins to fade or if reception
deteriorates, please replace with new alkali batteries.
Using manganese batteries reduces the lifespan.
• The attached batteries are provided for the initial use
of the system.
The usable period of the batteries may be short
depending on the manufactured date of the air
conditioner.

„ To operate the remote
controller
• To use the remote controller, aim the transmitter at
the indoor unit. If there is anything to block signals
between the unit and the remote controller, such
as a curtain, the unit will not operate.
• Do not drop the remote controller. Do not get it wet.
• The maximum distance for communication is
about 7m.

ATTENTION
„ About remote controller
• Never expose the remote controller to direct sunlight.
• Dust on the signal transmitter or receiver will reduce the
sensitivity. Wipe off dust with soft cloth.
• Signal communication may be disabled if an electronicstarter-type fluorescent lamp (such as inverter-type
lamps) is in the room. Consult the shop if that is the case.
• If the remote controller signals happen to operate another
appliance, move that appliance to somewhere else, or
consult the shop.

„ Turn the breaker ON
• Turning ON the breaker opens the flap, then

NOTE
„ Tips for saving energy
• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps
save energy.
Recommended temperature setting
For cooling:26˚C – 28˚C
For heating:20˚C – 24˚C
• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the cooling
(heating) effect.
• Clogged air filters cause inefficient operation and waste
energy. Clean them once in about every two weeks.
„ Please note
• The air conditioner always consumes 15-35 watts of electricity
even while it is not operating.
• If you are not going to use the air conditioner for a long period,
for example in spring or autumn, turn the breaker OFF.

Operation
Si10-416_B
ARC433 Series
NOTE
„ Note on HEAT operation
• Since this air conditioner heats the room by taking heat from
outdoor air to indoors, the heating capacity becomes smaller
in lower outdoor temperatures. If the heating effect is
insufficient, it is recommended to use another heating
appliance in combination with the air conditioner.
• The heat pump system heats the room by circulating hot air
around all parts of the room. After the start of heating
operation, it takes some time before the room gets warmer.
• In heating operation, frost may occur on the outdoor unit and
lower the heating capacity. In that case, the system switches
into defrosting operation to take away the frost.
• During defrosting operation, hot air does not flow out of
indoor unit.
„ Note on COOL operation
• This air conditioner cools the room by blowing the hot
air in the room outside, so if the outside temperature is
high, performance drops.
„ Note on DRY operation
• The computer chip works to rid the room of humidity
while maintaining the temperature as much as
possible. It automatically controls temperature and fan
strength, so manual adjustment of these functions is
unavailable.
„ Note on AUTO operation
• In AUTO operation, the system selects a temperature setting
and an appropriate operation mode (COOL or HEAT) based
on the room temperature at the start of the operation.
• The system automatically reselects setting at a regular
interval to bring the room temperature to user-setting level.
• If you do not like AUTO operation, you can manually
select the operation mode and setting you like.
„ Note on airflow rate setting
• At smaller airflow rates, the cooling (heating) effect is also
smaller.

Notes on flap angle
• When “SWING button” is selected, the flaps swinging
range depends on the operation mode.
Three-Dimensional (3-D) Airflow
• Using three-dimensional airflow circulates cold air,
which tends to collected at the bottom of the room, and
hot air, which tends to collect near the ceiling,
throughout the room, preventing areas of cold and hot
developing.
„ ATTENTION
• Always use a remote controller to adjust the flaps angle.

This system has one outdoor unit connected to multiple indoor units.
„ Selecting the Operation Mode
1. With the Priority Room Setting
present but inactive or not present.
When more than one indoor unit is operating, priority is
given to the first unit that was turned on.
In this case, set the units that are turned on later to the
same operation mode (*1) as the first unit.
Otherwise, they will enter the Standby Mode, and the
operation lamp will flash; this does not indicate malfunction.
(*1)
• COOL, DRY and FAN mode may be used at the
same time.
• AUTO mode automatically selects COOL mode or
HEAT mode based on the room temperature.
Therefore, AUTO mode is available when
selecting the same operation mode as that of the
room with the first unit to be turned on.

〈CAUTION〉
Normally, the operation mode in the room where the unit is first run
is given priority, but the following situations are exceptions, so
please keep this in mind.
If the operation mode of the first room is FAN Mode, then using
Heating Mode in any room after this will give priority to heating. In
this situation, the air conditioner running in FAN Mode will go on

(Available only for cooling operation)
NIGHT QUIET Mode requires initial programming during installation.
Please consult your retailer or dealer for assistance.
NIGHT QUIET Mode reduces the operation noise of the outdoor
unit during the night time hours to prevent annoyance to
neighbors.
• The NIGHT QUIET Mode is activated when the temperature drops
5˚C or more below the highest temperature recorded that day.
Therefore, when the temperature difference is less than 5˚C, this
function will not be activated.
• NIGHT QUIET Mode reduces slightly the cooling efficiency of the
unit.
„ OUTDOOR UNIT QUIET (SILENT)
Operation
1. With the Priority Room Setting present
but inactive or not present.
When using the OUTDOOR UNIT QUIET operation feature

following situations;
1. Operation Mode Priority.
As the operation mode of the Priority Room takes precedence,
the user can select a different operation mode from other
rooms.
〈Example〉
* Room A is the Priority Room in the examples.
When COOL mode is selected in Room A while operating
the following modes in Room B,C and D:
Operation mode in
Room B, C and D
Status of Room B, C and D when the unit

mode, it enters Standby Mode.
Operation resumes when the Room A
unit stops operating.
2. Priority when POWERFUL operation is used.
〈Example〉
* Room A is the Priority Room in the examples.
The indoor units in Rooms A,B,C and D are all operating.
If the unit in Room A enters POWERFUL operation,
operation capacity will be concentrated in Room A. In
such a case, the cooling (heating) efficiency of the units
in Rooms B,C and D may be slightly reduced.
3. Priority when using OUTDOOR UNIT
QUIET (SILENT) operation.
〈Example〉
* Room A is the Priority Room in the examples.
Just by setting the unit in Room A to QUIET operation, the
air conditioner starts OUTDOOR UNIT QUIET operation.
