Injury may result due to contact with the air conditioner’s highspeed fan blades.
Beware of a fire in case of refrigerant leakage.
If the air conditioner is not operating correctly,
i.e. not generating cool or warm air, refrigerant
leakage could be the cause. Consult your local
dealer for assistance. The refrigerant used for
the air conditioner is safe and normally does not
leak. However, if the refrigerant leaks and gets in
contact with a naked burner, heater or cooker, it
may generate hazardous compounds. Turn off
the air conditioner and call your local dealer.
Turn on the air conditioner after the qualified service person makes sure to confirm that the leakage is repaired.
Consult your local dealer regarding what to
do in case of refrigerant leakage.
When the indoor unit is installed in a small room,
it is necessary to take proper measures so that
the amount of any leaked refrigerant does not
exceed the concentration limit in the event of a
leakage. Otherwise, this may lead to an accident
due to oxygen depletion.

grille.
The guard protects against the unit’s high speed
fan, which may cause injury.
To avoid oxygen deficiency, ensure that the
room is adequately ventilated if equipment
such as a burner is used together with the air
conditioner.
Do not place flammable sprays or operate
spray containers near the air conditioner as
this may result in a fire.
Do not put flammable containers, such as
spray cans, within 1 m from the air outlet.
The containers may explode because the warm
air from the indoor or outdoor unit will affect them.

6. OPERATION CHARACTERISTICS
■ CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)
• If the COOLING OPERATION is used when the
indoor temperature is low, frost adheres to the
heat exchanger of the indoor unit.
This can decrease the cooling capacity.
In this case, the air conditioner automatically
switches to the DEFROST OPERATION for a
while.
English
During the DEFROST OPERATION, the low fan
speed or a gentle wind is used to prevent the discharge of melt water.
(The remote controller displays the fan speed that
is set.)
• When the outdoor temperature is high, it takes
some time until the indoor temperature reaches
the set temperature.
■ CHARACTERISTICS OF THE HEATING
OPERATION (HEATING OPERATION AND
AUTOMATIC HEATING OPERATION)
START OF OPERATION
• It generally takes a longer time for indoor temperature of the HEATING OPERATION to reach the
set temperature compared to the COOLING
OPERATION.
It is advisable to start operation in advance using
the TIMER OPERATION.
Perform the following operation to prevent heating capacity decrease and discharge of cool air.
AT THE START OF OPERATION AND AFTER
THE DEFROST OPERATION
• A warm air circulating system is employed, and
therefore it takes some time until the entire room
is warmed up after the start of operation.
• The indoor fan runs to discharge a gentle wind
automatically until the temperature inside the air
conditioner reaches a certain level. At this time,
the remote controller displays “
”. Leave it as
it stands and wait for a while.
(The remote controller displays the fan speed that
is set.)
• The airflow direction becomes horizontal to prevent a draft of cool air to the inhabitants. (The
remote controller displays the set airflow direction
that is set.)
DEFROST OPERATION
(Frost removal operation for the outdoor
unit)
• As the frost on the coil of an outdoor unit increase,
heating effect decreases and the air conditioner
goes into the DEFROST OPERATION.
• The indoor unit fan stops and the remote controller display shows “
”.
With the wireless remote controller, the warm air
stops, and the DEFROST OPERATION lamp on
the light receiving unit turn on.
(The remote controller displays the fan speed that
is set.)
• After maximum 10 minutes of the DEFROST
OPERATION, the air conditioner returns to the
HEATING OPERATION.
6
01_EN_3P170549-16R.fm Page 7 Monday, September 24, 2012 4:59 PM
• The airflow direction becomes horizontal. (The
remote controller displays the airflow direction
that is set.)
• During or after the DEFROST OPERATION, white
mist comes out from the air inlet or outlet of the air
conditioner.
(Refer to “VI.” on page 13.)
• A hissing and “Shuh” sound may be heard during
this particular operation.
Regarding outside air temperature and heating capacity
• The heating capacity of the air conditioner
declines as the outside air temperature falls.
In such a case, use the air conditioner in combination with other heating systems.
(When a combustion appliance is used, ventilate
the room regularly.)
Do not use the combustion appliance where the air
from the air conditioner is blown directly toward it.
• When the warm air stays under the ceiling and
your feet are cold, we recommend that you use a
circulator (a fan to circulate the air inside the
room).
For details, consult your local dealer.
• When the indoor temperature exceeds the set
temperature, the indoor unit discharges a gentle
breeze (switches to gentle wind). The airflow
direction becomes horizontal. (The remote controller displays the fan speed and airflow direction
that are set.)
■ CHARACTERISTICS OF THE PROGRAM
DRY OPERATION
• This operation lowers the humidity without lowering the indoor temperature. The indoor temperature when the operation button is pressed will be
the set temperature. At this time, the fan speed
and temperature are set automatically, so the
remote controller does not display the fan speed
and set temperature.
To efficiently lower the indoor temperature and
humidity, first use the COOLING OPERATION to
lower the indoor temperature, and then use the
PROGRAM DRY OPERATION. When the indoor
temperature is lowered, airflow from the indoor
unit may stop.
• When operating continuously at downward airflow
direction, air blows in the automatic set direction
for a period of time to prevent condensation on the
horizontal blades. (The remote controller displays
the airflow direction that is set.)
7
• If the PROGRAM DRY OPERATION is used when
the indoor temperature is low, frost forms the heat
exchanger of the indoor unit. In this case, the air
conditioner automatically switches to the
DEFROST OPERATION for a while.
The low fan speed or a gentle wind is used to prevent the discharge of melt water.
AIRFLOW DIRECTION ADJUST
Airflow direction adjust can be individually set for
each air outlet. (BRC1E52 only)
• Check the air outlet identification mark (refer to
page 5), and use the remote controller to set the
airflow direction. (For details, refer to the operation manual attached to the remote controller.)
• The horizontal blades at the air outlet are closed
while the indoor unit stops.
AIRFLOW DIRECTION ADJUST
Press the AIRFLOW DIRECTION ADJUST/SETTING button to adjust the airflow direction.
Up and down adjustment

7. OPTIMUM OPERATION
Observe the following precautions to ensure the air
conditioner operates.
• Prevent direct sunlight from the window by using
curtains or blinds during the COOLING OPERATION.
• Keep doors and windows closed. If the doors and
windows remain open, room air will flow out and
decrease the effect of cooling and heating.
• Never place objects near the air inlet and the air
outlet of the air conditioner. It may decrease the
effect or stop the operation.
• Adjust the room temperature properly for a comfortable environment. Avoid excessive heating or
cooling.
Not doing so wastes electricity.
• When the display shows “
” or “Time to clean
filter”, ask a qualified service person to clean the
filters.
(Refer to “8. MAINTENANCE” on page 9.)
Operating the indoor unit with stained air filter
may decrease capacity or cause malfunction.
• Install TVs, radios, and stereos 1 m or more away
from the indoor unit and remote controller.
Images may become fuzzy and noise may be
generated.
• Turn off the power circuit breaker when it is not in
use for a long period. When the power circuit
breaker is turned on, small amount of power is
consumed even if the air conditioner is not in
operation. (*1)
Turn off the power circuit breaker for saving
energy. When reoperating, turn on the power circuit breaker 6 hours before operation for smooth
running.
(Refer to “8. MAINTENANCE” on page 9.) (*2)
*1 The consumed power while the outdoor unit is
not in operation depends on the model.
*2 The setting before the power circuit breaker is
cut off is stored. (The timer setting is cleared.)
• Fully use the function of airflow direction adjust.
Cold air gathers on the floor, and warm air gathers
under the ceiling.
Set the air direction to horizontal during the
COOLING or PROGRAM DRY OPERATION, and
set it downwards during the HEATING OPERATION.
Do not let the air blow directly to a person.
• Use the TIMER OPERATION effectively.
It takes some time until the indoor temperature
reaches the set temperature. It is advisable to
start operation in advance using the TIMER
OPERATION.

9. NOT MALFUNCTION OF THE
AIR CONDITIONER
9-1. FUQ
The following symptoms do not indicate air conditioner malfunction
• HEATING OPERATION within 6 hours after the
power is supplied to the air conditioner.
Some model series perform the following operation to protect the devices.
If the HEATING OPERATION is performed within
6 hours after the power is supplied to the air conditioner, the indoor fan stops for about 10 minutes during the outdoor unit operation to protect the devices.
The above operation is performed not only for
installation, but every time the power circuit
breaker is turned off/on.
For comfortable use, do not turn off the power circuit breaker during seasonal use of the HEATING
OPERATION.
I. THE AIR CONDITIONER DOES NOT OPERATE
• The air conditioner does not restart immediately after the ON/OFF button is pressed.
• The air conditioner does not restart
immediately when TEMPERATURE SETTING button is returned to the former
position after pushing the button.
If the OPERATION lamp lights, the air conditioner is in normal condition.
It does not restart immediately because a
safety device operates to prevent overload of
the air conditioner.
After 3 minutes, the air conditioner will start
again automatically.
• The air conditioner does not start when
the display shows “
” and it
flashes for few seconds after pressing an
operation button.
This is because the air conditioner is under
centralized control.
Flashes on the display indicates that the air
conditioner cannot be controlled by the
remote controller.
• HEATING OPERATION within 6 hours after
power is supplied to the air conditioner.
Some model series perform the following
operation to protect the devices.
If the HEATING OPERATION is performed
within 6 hours after power is supplied to the
air conditioner, the indoor fan stops for about
10 minutes during the outdoor unit operation
to protect the devices.
The above operation is performed not only
for installation, but every time the power circuit breaker is turned off/on.
English
For comfortable use, do not turn off the
power circuit breaker during seasonal use of
the HEATING OPERATION.
• The outdoor unit stops.
This is because the indoor temperature has
reached the set temperature.
The indoor unit is in the FAN OPERATION.
COOLING OPERATION
(AUTOMATIC COOLING OPERATION):
Lower the set temperature.
HEATING OPERATION
(AUTOMATIC HEATING OPERATION):
Raise the set temperature.
The operation starts after a while when the
air conditioner is in normal condition.
• The remote controller displays “
”,
and airflow stops.
This is because the air conditioner automatically switches to the DEFROST OPERATION
to prevent a decrease in heating capacity
when frost on the outdoor unit increases.
After maximum 10 minutes, the air conditioner returns to its original operation.
II. THE OPERATION SOMETIMES STOPS
• The remote controller displays “U4” and
“U5”, and the operation stops. However, it
will restart in a few minutes.
This is because communication between the
indoor and outdoor units or indoor units and
remote controllers is shut off and stopped
due to noise caused by devices other than
the air conditioner.
When the electrical noise decreases, the air
conditioner automatically restarts.
III. THE FAN SPEED IS DIFFERENT FROM THE
SETTING
• Pressing the fan speed control button
does not change the fan speed.
During the COOLING OPERATION, the low
fan speed or a gentle wind is used to prevent
the discharge of melt water.
During the DEFROST OPERATION (HEATING OPERATION), the wind from the air conditioner stops to prevent air discharge
directly toward your body. After a while, the
fan speed can be changed.
(The fan speed cannot be set for the PROGRAM DRY OPERATION.)
When the room temperature reaches the set
temperature during the HEATING OPERATION, the outdoor unit stops and the indoor
unit goes into gentle wind.
It takes some time until the fan speed changes.
Raise the set temperature.
After a while, the fan speed changes.
12
01_EN_3P170549-16R.fm Page 13 Monday, September 24, 2012 4:59 PM
IV. THE AIRFLOW DIRECTION IS DIFFERENT
FROM THE SETTING, OR THE AIRFLOW
DIRECTION IS DIFFERENT FROM THE DISPLAY ON THE REMOTE CONTROLLER
• The horizontal blades do not swing when
the remote controller displays the swing
operation.
<HEATING OPERATION>
This is because the airflow direction is controlled so it is horizontal direction after the
operation starts or when the indoor temperature is higher than the set temperature to prevent air discharge directly toward your body.
After a while, the swing operation starts.
(Refer to “MOVEMENT OF THE HORIZONTAL BLADE” on page 8.)
• The airflow direction display of the
remote controller differs from the actual
operation of the horizontal blades.
<COOLING and PROGRAM DRY OPERATIONS>
When the operation in a downward airflow
direction is set, the airflow direction differs
from the display for a period of time to prevent condensation on the horizontal blades.
<HEATING OPERATION>
This is because the airflow direction is controlled so it is horizontal direction after the
operation starts or when the indoor temperature is higher than the set temperature to
prevent air discharge directly toward your
body.
After a while, the airflow direction changes
to the set direction.
(Refer to “MOVEMENT OF THE HORIZONTAL BLADE” page 8.)
V. HORIZONTAL BLADES DO NOT CLOSE
• The horizontal blades do not close even
when operation stops.
This is because the horizontal blades close
once airflow from the air conditioner stops.
After a while, the horizontal blades close.
VI. WHITE MIST COMES OUT OF THE AIR CONDITIONER
• When humidity is high during the COOLING OPERATION. (In oily or dusty places)
If the inside of an indoor unit is extremely
contaminated, the temperature distribution
inside a room becomes uneven.
It is necessary to clean the inside of the
indoor unit.
Ask your local dealer for details on cleaning
the indoor unit.
This cleaning requires a qualified service
person.
Check the usage environment.
13
• When the air conditioner is changed over
to the HEATING OPERATION after the
DEFROST OPERATION and in the
DEFROST OPERATION.
Moisture generated by defrost becomes
steam and exists.
When the remote controller display shows
“
”, DEFROST OPERATION is being
used.
VII. NOISE OF AIR CONDITIONERS
• A ringing sound after the indoor unit is
started.
This sound is generated when the motors for
driving the horizontal blades are working.
It will quiet down after about a minute.
• A low continuous flow “Shuh” sound
which is heard when the air conditioner is
in the COOLING or DEFROST OPERATION or a trickling sound which is heard
when the air conditioner is in the
DEFROST OPERATION.
This is the sound of refrigerant gas flowing
through both indoor and outdoor units.
• A “Shuh” sound which is heard at the
start or immediately after the stop of
operation or which is heard at the start or
immediately after the stop of the
DEFROST OPERATION.
This is the noise of refrigerant caused by flow
stop and flow change.
During the HEATING OPERATION, the air
conditioner switches to the DEFROST
OPERATION automatically.
The remote controller shows “
”.
After maximum 10 minutes, the air conditioner returns to its original operation.
• A continuous flow “Shah” sound is heard
when the air conditioner is in the COOLING OPERATION or at a stop.
The noise is heard when the drain pump is in
operation.
Liquid removed from the indoor air during the
COOLING OPERATION is discharged.
• A “Pishi-pishi” squeaking sound is heard
when the air conditioner is in operation or
after the stop of operation.
Expansion and contraction of resin parts
caused by temperature change makes this
noise.
VIII. DUST FROM THE INDOOR UNITS
• Dust may blow out from the unit after
starting operation from long resting time.
Dust absorbed by the unit blows out.
English
01_EN_3P170549-16R.fm Page 14 Monday, September 24, 2012 4:59 PM
IX. THE INDOOR UNITS GIVE OFF ODORS
• During operation
The unit absorbs the smell of rooms, furniture, cigarettes, etc., and then emits them.
If odor is a concern, set the fan speed to no
airflow when the indoor temperature reaches
the set temperature.
For details, contact your local dealer.
X. THE AIR CONDITIONER DOES NOT COOL
EFFECTIVELY
• The air conditioner is operating in PROGRAM DRY OPERATION.
This is because program dry mode operates
so that the indoor temperature decreases as
little as possible.
Lower the indoor temperature using the
COOLING OPERATION, and then use the
PROGRAM DRY OPERATION.
(Refer to “CHARACTERISTICS OF THE
PROGRAM DRY OPERATION” on page 7.)
• Read through characteristics of the
COOLING OPERATION, characteristics of
the HEATING OPERATION, and characteristics of the PROGRAM DRY OPERATION
