Safety Precautions
Keep this manual where the operator can easily fi nd it.•
Read this manual carefully before starting the unit.•
For safety reason, the operator must read the following cautions carefully.•
This manual classifi es precautions into DANGER, WARNING and CAUTION. Be sure to follow all precautions below: they are all •
important for ensuring safety.
DANGER WARNING CAUTION
Indicates an imminently hazardous
situation which, if not avoided, will result
in death or serious injury.
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.
If you do not follow these instructions
exactly, the unit may cause property
damage, personal injury or loss of life.
Be sure to follow the instructions.
Never cause the air conditioner (including the remote
controller) to get wet.
If you do not follow these instructions exactly,
the unit may cause minor or moderate
property damage or personal injury.
WARNING
It is not good for health to expose your body to the air fl ow for a long time.•

ATTENTION
About batteries
When replacing the batteries, use batteries of the same type, and replace the 2 old batteries together.•
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 2 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.
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 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 64°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 (64°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.
