Tips for saving energy
A.
Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases
the cooling/heating effect.
B.
Be careful not to cool the room too much.
Keeping the temperature setting at a moderate level
helps save energy.
C
A
B
„ Recommended temperature setting
• For cooling: 26-28°C
• For heating: 20-24°C
C.
Keep air filter clean.
Clogged air filters cause inefficient operation and waste energy.
When the AUTO CLEANING FILTER operation is enabled, the
air conditioner cleans the filter periodically. Efficient operation is
available at any time without concerns about dirt.  Page 28

Tips for your comfort
INTELLIGENT EYE sensor
When the INTELLIGENT EYE sensor is used, the sensor detects the movement
of a person and adjusts the airflow direction and operation.
Do you want to direct the airflow away from you?
Do you want to save power consumption in a room with no person in it?
The sensor will cooperate with you.  Page 15, 16
FLASH STREAMER

Before Operation
Safety precautions
Read the precautions in this manual carefully
before operating the unit.
This appliance is filled with R32.
• Keep this manual where the user can easily find it.
• The precautions described herein are classified as WARNING and CAUTION. They both contain important information regarding safety.
Be sure to observe all precautions without fail.
WARNING ..................... Failure to follow these instructions properly may result in personal injury or loss of life.
CAUTION ......................
Never attempt.
Failure to observe these instructions properly may result in property damage or
personal injury, which may be serious depending on the circumstances.
Be sure to follow the instructions.
Be sure to establish an earth
connection.
• After reading, keep this manual in a convenient place so that you can refer to it whenever necessary. If the equipment is transferred to a
new user, be sure also to hand over the manual.
WARNING
• Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer.
• The appliance must be stored in a room without continuously operating ignition sources (for example: open flames, an
operating gas appliance or an operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• The appliance must be installed, operated and stored in a room with a floor area larger than 1.8m2.
• In order to avoid fire, explosion or injury, do not operate the unit when harmful, among which flammable or corrosive gases, are
detected near the unit.
• Be aware that prolonged, direct exposure to cool or warm air from the air conditioner, or to air that is too cool or too warm can
be harmful to your physical condition and health.
• Do not place objects, including rods, your fingers, etc., in the air inlet or outlet. Product malfunctioning, product or injury
damage may result due to contact with the air conditioner’s high-speed fan blades.
• Do not attempt to repair, dismantle, reinstall or modify the air conditioner yourself as this may result in water leakage, electric
shocks or fire hazards.
• Do not use flammable spray near the air conditioner, or otherwise fire may result.
• Do not use a refrigerant other than the one indicated on the outdoor unit (R32) when installing, moving or repairing. Using
other refrigerants may cause trouble or damage to the unit, and personal injury.
• To avoid electric shocks, do not operate with wet hands.
• Beware of 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 dealer for assistance. The refrigerant within the air conditioner is safe and
normally does not leak.
However, in the event of a leakage, contact with a naked burner, heater or cooker may result in generation of noxious gas. Do
not use the air conditioner until a qualified service person confirms that the leakage has been repaired.
• Do not attempt to install or repair the air conditioner yourself. Improper workmanship may result in water leakage, electric
shocks or fire hazards. Please contact your local dealer or qualified personnel for installation and maintenance work.
• When the air conditioner is malfunctioning (giving off a burning odour, etc.) turn off power to the unit and contact your local
dealer. Continued operation under such circumstances may result in a failure, electric shocks or fire hazards.
• Be sure to install an earth leakage circuit breaker. Failure to install the earth leakage circuit breaker may result in electric
shocks or fire.
• Be sure to earth the unit. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing
may result in electric shocks.
CAUTION
• Do not use the air conditioner for purposes other than those for which it is intended. Do not use the air conditioner for cooling
precision instruments, food, plants, animals or works of art as this may adversely affect the performance, quality and/or
longevity of the object concerned.
• Do not expose plants or animals directly to airflow from the unit as this may cause adverse effects.

Before Operation
• Do not place appliances that produce naked flames in places exposed to the airflow from the unit as this may impair
combustion of the burner.
• Do not block air inlets nor outlets. Impaired airflow may result in insufficient performance or trouble.
• Do not sit on the outdoor unit, put things on the unit, or pull the unit. Doing so may cause accidents, such as falling or toppling
down, thus resulting in injury, product malfunctioning, or product damage.
• Do not place objects that are susceptible to moisture directly beneath the indoor or outdoor units. Under certain conditions,
condensation on the main unit or refrigerant pipes, air filter dirt or drain blockage may cause dripping, resulting in fouling or
failure of the object concerned.
• After prolonged use, check the unit stand and its mounts for damage. If they are left in a damaged condition, the unit may fall
and cause injury.
• To avoid injury, do not touch the air inlet or aluminium fins of the indoor or outdoor units.
• The appliance is not intended for use by unattended young children or infirm persons. Impairment of bodily functions and harm
to health may result.
• Children should be supervised to ensure that they do not play with the unit or its remote controller. Accidental operation by a
child may result in impairment of bodily functions and harm health.
• Avoid impacts to the indoor and outdoor units, or otherwise product damage may result.
• Do not place flammable items, such as spray cans, within 1m of the air outlet.
The spray cans may explode as a result of hot air from the indoor or outdoor units.
• Be careful not to let pets urinate on the air conditioner. Urination on the air conditioner may result in electric shocks or fire.
• Do not wash the air conditioner with water, as this may result in electric shocks or fire.
• Do not place water containers (vases etc.) above the unit, as this may result in electric shocks or fire hazards.
• To avoid oxygen depletion, ensure that the room is adequately ventilated if equipment such as a burner is used together with
the air conditioner.
• Before cleaning, be sure to stop unit operation, turn off the circuit breaker or remove the power cord. Otherwise, an electric
shock and injury may result.
• Only connect the air conditioner to the specified power supply circuit. Power supplies other than the one specified may result in
electric shocks, overheating and fires.
• Arrange the drain hose to ensure smooth drainage. Imperfect drainage may cause wetting of the building, furniture etc.
• Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris accumulate around the unit.
Leaves are a hotbed for small animals which can enter the unit. Once in the unit, such animals can cause malfunctions, smoke
or fire when making contact with electrical parts.
• Do not place objects around the indoor unit.
Doing so may have an adverse influence on the performance, product quality, and life of the air conditioner.
• This appliance is not intended to be used by persons with reduced physical, sensory or mental capabilities, or with lack of
operation knowledge, unless they have been given supervision or instruction concerning the appliance use by person
responsible for their safety.
Keep out of children’s reach to ensure that they do not play with the appliance.
• For care and cleaning, call service personnel.
P002
This is an appliance that is not accessible to the general public.
Installation site
< To install the air conditioner in the following types of environments, consult the dealer >
• Places with an oily environment or where steam or soot occurs.
• Salty environment such as coastal areas.
• Places where sulfide gas occurs such as hot springs.
• Places where snow may block the outdoor unit.
• The indoor unit is at least 1m away from any television or radio set (unit may cause interference with the picture or sound).
• The drain from the outdoor unit must be discharged to a place of good drainage.
Consider nuisance to your neighbours from noises
< For installation, choose a place as described below >
• A place solid enough to bear the weight of the unit which does not amplify the operating sound or vibration.
• A place from where the air discharged from the outdoor unit or the operating sound will not annoy your neighbours.
Electrical work
• For power supply, be sure to use a separate power circuit dedicated to the air conditioner.
System relocation
• Relocating the air conditioner requires specialized knowledge and skills. Please consult the dealer if relocation is necessary for
moving or remodeling.

Notes on “SARARA” DRY operation
•
•
•
•
This mode mixes dehumidified cool air with room air to adjust the air outlet temperature and remove moisture.
When the indoor temperature rises, the DRY COOLING operation automatically starts.
When the outdoor temperature is lower than the indoor temperature, dehumidifying is less effective.
When the outdoor temperature is lower than 18ºC, the room is dehumidified by alternating the COOLING and HEATING operations. In
addition, the ventilation is controlled properly and the room humidity is lowered by taking outdoor air into the room. (Air intake
dehumidifying)
Notes on DRY COOLING operation
• In order to lower the humidity, the airflow rate during the DRY COOLING operation becomes lower than that in the COOLING operation.
• When the humidity is not lowered, “SARARA” DRY operation automatically starts.
Note on “URURU” HUMIDIFY operation
• The humidifying unit collects moisture from the outdoor air to humidify the room.
Note on HUMID HEATING operation
• When the indoor temperature rises by HEATING operation, the indoor humidity may drop temporarily.

• When the airflow rate setting is “AUTO”, starting COOLING, “SARARA” DRY, or DRY COOLING operation (including the operation
selected with “AUTO”) triggers the deodorising function which reduces odour coming from the indoor unit and the unit does not blow air
immediately. Wait for about 40 seconds. (SMELL PROOF)
• When the airflow rate is lowered, the flaps and louvres will stop. When the vertical airflow direction is set to “Swinging”, the flaps stop in

To adjust the airflow
Note on 3-D airflow
• Using 3-D airflow circulates cold air, which tends to collect 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.
Note on horizontal airflow direction
• When the horizontal airflow direction is set to “AUTO”, the INTELLIGENT EYE sensor is activated. The INTELLIGENT EYE sensor
detects a person in the left-side, front, and right-side areas and directs the airflow away from that person.
< INTELLIGENT EYE sensor >
The INTELLIGENT EYE sensor detects the movements of a person (heat-generating object) to confirm where people are.
Example (for Comfort)  Page 16
• The maximum distance that people can be detected is about 9m in front of the indoor unit.
• The movement of small animals including dogs and cats or a temperature change due to a heat-generating object such as another
heating appliance or electrical appliance may incorrectly be detected as a person. In addition, areas exposed to sunlight may
incorrectly be detected as a person.
• If several persons are detected in the same room, the airflow direction is changed based on the position of the last detected
person.
• The area just under or right beside the indoor unit cannot be detected.
• Application range is as follows.

FAQ
Indoor unit
Commonly occurring sounds
„ A hissing sound
• This is a sound generated when humidified air or
ventilated air is discharged.
• Operating sound may vary depending on the outdoor
temperature or humidity.
„ Roaring sound
• This is a sound of ventilating operation. (When ventilating
operation is combined with COOLING/HEATING
operation, it is possible to stop only ventilating operation.)
The flaps do not start swing immediately.
• The air conditioner is adjusting the flaps position. The flaps
will start moving soon.
The air conditioner stops generating airflow
during operation.
• Once the set temperature is reached, the airflow rate is
reduced and operation stopped in order to avoid generating
cool airflow (during heating) or in order to keep the humidity
from rising (during cooling). Operation will resume
automatically when the indoor temperature rises or falls.
Operation does not start soon.
„ When AUTO button, direct operation buttons or FAN
ONLY button was pressed soon after operation was
stopped.
„ When the mode was reselected.
• This is to protect the air conditioner. You should wait for
about 3 minutes.
The HEATING operation stops suddenly and
a flowing sound is heard.
• The outdoor unit is taking away the frost. The HEATING
operation starts after the frost on the outdoor unit is
removed. You should wait for about 3 to 10 minutes.
 Page 24
„ Hissing or cracking sound
• This is a sound of streamer discharge.
„ Rustling sound
• This is a sound of the dust brush rubbing the air filter to
remove dust from the air filter in CLEANING FILTER
operation.
„ Clicking sound while the air conditioner is or is not in
operation
• This is a sound of operation of the electric components or
valve that controls the refrigerant.
„ A sound like a flow of water
• This is a sound of the refrigerant flowing in the air
conditioner.
• This is a pumping sound of the water in the air conditioner
and heard when the water is pumped out from the air
conditioner in cooling or drying operation.
„ Blowing sound
• This is a sound generated when the direction of the flow of
the refrigerant changes in the air conditioner.
„ Ticking sound
• This is a sound generated when the air conditioner slightly
expands or shrinks due to temperature change.
„ Clopping sound
• This is a sound that comes from the inside of the air
conditioner when the ventilating fan is operated with the
room closed. This sound may decrease when the window
is opened or the ventilating fan is stopped.
„ Whistling sound
• This is a sound generated when the refrigerant flows
during defrosting operation.
Outdoor unit
The outdoor unit emits water or steam.
„ In HEATING operation
• The frost on the outdoor unit melts into water or steam when the air conditioner is in
defrost operation.
„ In COOLING or “SARARA” DRY operation
• Moisture in the air condenses into water on the cool surface of outdoor unit piping
and drips.

Troubleshooting (for service personnel)
The room does not cool down/warm up
Case
Air does not come out.
Description / where to check
„ In HEATING operation
• The air conditioner is warming up. Wait for about 1 to 4 minutes.
„ In COOLING / “SARARA” DRY / DRY COOLING operation
• When the airflow rate setting is “AUTO”, a function to prevent emission of an odour
contained in the indoor unit operates. This keeps air from coming out immediately after
operation is started. Wait for about 40 seconds.  Page 14

 Page 24
Air has an odour
Case
The air conditioner gives off an
odour.
Description / where to check
• The air conditioner may take in an odour from outside. Stop humidifying operation and
remove the cause of the odour.
• When operation is switched to “SARARA” DRY operation, the humidity may increase
temporarily, which may generate an odour.
• The room odour absorbed in the unit is discharged with the airflow.
We recommend you to have the indoor unit cleaned. Consult the service shop.
• The air outlet may give out an odour because a small amount of ozone is generated.
However, the amount is very small and does not harm your health.
• This happens when the unit is in MOLD PROOF operation.  Page 27
Commonly occurring sounds
Case
Sound occurs during humidifying
operation.
Description / where to check
„ Operating sound is loud
• In HUMID HEATING operation, the humidifying unit starts operating and therefore
generates a slightly louder sound in the room. This sound is generated by the humidifying
operation which becomes louder with increases in the airflow rate.
• In ventilating operation, fresh air is taken in from outside. This may cause outside noise
to sound loud. Operating sound becomes slightly louder as well.  Page 24
„ Operating sound changes
• This happens when the humidifying fan starts or stops operating.
• Outside sound may be loud.
Sound keeps coming out of the
indoor unit even after humidifying
operation is stopped.
• To protect the air conditioner, the humidifying fan keeps turning for about another
3 minutes after operation is stopped.
Mist comes out
Case
Mist comes out of the indoor unit.
Description / where to check
• This happens when the air in the room is cooled into mist by the cold airflow during
COOLING or other operation.
• This is because the air in the room is cooled by the heat exchanger and becomes mist
during defrost operation.
