Meanings of DANGER, WARNING, CAUTION, and NOTE Symbols:
DANGER
Indicates an imminently hazardous situation
which, if not avoided, will result in death or
serious injury.
WARNING
Indicates a potentially hazardous situation
which, if not avoided, could result in death
or serious injury.
Never do.
CAUTION
Indicates a potentially hazardous situation
which, if not avoided, may result in minor or
moderate injury. It may also be used to alert
against unsafe practices.
Be sure to follow the instructions.
Be sure to ground the air conditioner.
Never touch the air conditioner (including the remote
controller) with a wet hand.
Never allow the air conditioner or remote controller to get
wet.
DANGER
• For refrigerant leakage, consult your dealer.
Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion, especially in basements,
and an asphyxiation hazard could occur leading to serious injury or death.
• Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan heater, stove or cooking device. Exposure
to this gas could cause severe injury or death.
• Any abnormalities in the operation of the air conditioner such as smoke or fire could result in severe injury or death.
Turn off the power and contact your dealer immediately for instructions.
• Do not install the unit in an area where flammable materials are present due to risk of explosion resulting in serious injury or death.
• If equipment utilizing a burner is used in the same room as the air conditioner, there is the danger of oxygen deficiency which could
lead to an asphyxiation hazard resulting in serious injury or death.
Be sure to ventilate the room sufficiently to avoid this hazard.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries. Tear apart and throw away
plastic packaging bags so that children will not play with them. Children playing with plastic bags face the danger of death by
suffocation.
WARNING
• It is not good for health to expose your body to the air flow for a long time.
• Do not put your finger or other objects into the air outlet or inlet as the fan is rotating at high speed and could cause injury. Always
keep small children away from the unit during operation.
• Do not attempt to repair, relocate, modify or reinstall the air conditioner by yourself. Incorrect work or modifications could cause
electric shocks, fire or other damage.
For repairs and reinstallation, consult your Daikin dealer for advice and information.
• If the air conditioner is not cooling (heating) properly, the refrigerant may be leaking, contact your authorized dealer or qualified
service repairman.
When making repairs which requires adding refrigerant, consult with your authorized dealer or qualified service repairman.
• Do not attempt to install the air conditioner by yourself. Improper installation could result in water leakage, electric shocks or fire. For
installation, consult your authorized dealer or a qualified technician.
CAUTION
• The air conditioner must be grounded. Improper grounding may result in electric shocks. Do not connect the grounding wire to a gas
pipe, water pipe, lightning rod, or a telephone ground line. Follow all local and state electrical codes.

„ Notes on batteries
• When replacing the batteries, use batteries of the same type, and replace both batteries at the same time.
• When the system is not used for a long time, take the batteries out.
• The batteries will last for approximately 1 year. If the remote controller display begins to fade and the degradation of reception performance
occurs within a year, however, replace both batteries with new, size AAA.LR03 (alkaline).
• 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.
„ Notes on 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 a soft cloth.
• Signal communication may be disabled if an electronic-starter-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 somewhere else, or consult the service shop.
„ Celsius/Fahrenheit display change function of remote controller
• The set temperature may increase when the display is changed to Celsius from Fahrenheit, because a fraction of 0.5°C is rounded up.
• Example: A set temperature of 65°F (equivalent to 18.5°C) will be converted into 19°C.
When the display is changed to Fahrenheit again, the set temperature will be converted into 66°F (equivalent to 19°C) instead of the
original set temperature (65°F) but a set temperature of 66°F (equivalent to 19°C) will be converted into 19°C with no temperature change.
• A reception sound will go off for the transmission of set temperature to the indoor unit at the time of setting the Celsius/Fahrenheit display change function.

Notes on each operation mode
HEAT
• 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 HEAT operation, it takes
some time before the room gets warmer.
• In HEAT 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.
COOL
• This air conditioner cools the room by releasing the heat in the room outside. Therefore, the cooling performance of the air
conditioner may be degraded if the outdoor temperature is high.
DRY
AUTO
FAN
• The computer chip works to rid the room of humidity while maintaining the temperature as much as possible. It automatically
controls temperature and airflow rate, so manual adjustment of these functions is unavailable.
• In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT) based on the room and outside
temperatures and starts the operation.
• The system automatically reselects setting at a regular interval to bring the room temperature to user-setting level.
• This mode is valid for fan only.

Troubleshooting
„ These incidents are not malfunctions.
• The following incidents do not indicate a malfunctioning air conditioner and have explanations. The air conditioner can continue
to operate.
Indoor unit
The louvers do not immediately swing.
The louvers move soon after startup.
• The air conditioner is adjusting the louvers position. The
louvers will start moving soon.
The HEAT operation stops suddenly
and a flowing sound is heard.
• The outdoor unit is taking away the frost. The HEAT
operation starts after the frost on the outdoor unit is
removed. You should wait for about 4 to 12 minutes.
Possible sounds.
„ Flowing water
• Generated because the refrigerant in the air
conditioner is flowing.
• This is a pumping sound of the water in the air
conditioner it is heard when the water is pumped out
from the air conditioner in cooling or drying operation.
• The refrigerant flows in the air conditioner even if
the air conditioner is not working when the indoor
units in other rooms are in operation.
„ Blowing
• Generated when the flow of the refrigerant in the
air conditioner is switched over.
„ Pinging
Operation does not start soon.
„ When “ON/OFF” 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.
• Generated when the size of the air conditioner slightly
expands or shrinks as a result of temperature changes.
„ Clicking sound during operation or idle
time
• Generated when the refrigerant control valves or
the electrical parts operate.
„ Clopping sound
• Heard from the inside of the air conditioner when the
exhaust fan is activated while the room doors are closed.
Open the window or turn off the exhaust fan.
Outdoor unit
The outdoor unit emits water or steam.
„ In HEAT operation
• The frost on the outdoor unit melts into water or steam when the air
conditioner is in defrost operation.
„ In COOL or DRY operation
• Moisture in the air condenses into water on the cool surface of outdoor unit
piping and drips.

Hot air does not flow out soon after
the start of HEAT operation.
• The air conditioner is warming up. You should wait for
1 to 4 minutes. (The system is designed to start
discharging air only after it has reached a certain
temperature.)
Mist comes out of the indoor unit.
• This happens when the air in the room is cooled into
mist by the cold airflow during COOL operation.
• This is because the air in the room is cooled by the heat
exchanger and becomes mist during defrosting
operation.
Operation stopped suddenly.
(OPERATION lamp is on.)
• For system protection, the air conditioner may stop
operating on a sudden large voltage fluctuation. It
automatically resumes operation in about 3 minutes.
