against unsafe practices.
Never do.
Be sure to ground the air conditioner.
Never touch the air conditioner (including the remote
controller) with a wet hand.
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 fi re 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 fi re 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 fl ammable 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 defi ciency which could •
lead to an asphyxiation hazard resulting in serious injury or death.
Be sure to ventilate the room suffi ciently 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 fl ow for a long time.•
Do not put your fi nger 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 modifi cations could cause •
electric shocks, fi re 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 qualifi ed •
service repairman.
When making repairs which requires adding refrigerant, consult with your authorized dealer or qualifi ed service repairman.
Do not attempt to install the air conditioner by yourself. Improper installation could result in water leakage, electric shocks or fi re. For •
installation, consult your authorized dealer or a qualifi ed technician.
Be sure to follow the instructions.
Never allow the air conditioner or remote controller to get
wet.

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 soft cloth.•
Signal communication may be disabled if an electronic-starter-type fl uorescent 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 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.

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 insuffi cient, 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 fl ow out of indoor unit.
•
Note on COOL operation
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.
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 airfl ow rate, so manual adjustment of these functions is unavailable.
Note on AUTO operation
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.
•
Note on FAN operation
This mode is valid for fan only.•
Note on airfl ow rate setting
At smaller airfl ow rates, the cooling (heating) effect is also smaller.•
