CAUTION
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, a rod or other objects into the air outlet or inlet. As the fan is rotating at a high
•
speed and could, cause injury. Always keep small children away from the unit during operation.

Notes
Temperature indication change between Celsius and Fahrenheit on the remote controller
Change the temperature indication in the modes other than the DRY mode.
In the DRY mode, temperature indication setting cannot be changed because the temperature is not indicated.
When the Fahrenheit temperature indication is changed to Celsius one, the temperature value
(0.5°C) will be rounded up. Thus, the preset temperature may be changed.
Example:
A preset temperature of 65°F (equivalent to 18.5°C) will be changed to 19°C (66°F) by changing the temperature indication.
In this case, if you change the Celsius temperature indication again to the Fahrenheit one, the preset temperature is shown not as 65°F but
as 66°F (equivalent to 19°C). If the preset temperature is 66°F (equivalent to 19°C) and is changed to the Celsius temperature indication,
the indication becomes 19°C (66°F). In this case, no change by the temperature indication change is observed.
When the temperature indication change is set, the preset temperature is transmitted to the
indoor unit so that the reception sound will be heard from the indoor unit.

Heating operation
Since the heating operation is performed by
taking the heat from outdoor into the room,
the heating capacity decreases as the outdoor
temperature lowers. If the room is not heated
sufficiently, it is recommended to use other
heating appliance at the same time.
Since the air conditioner heats the whole room
by circulating hot air, it takes some time to
heat the entire room completely.

If the outdoor unit gets frosted during heating
operation, the heating capacity is decreased.
In this case, the unit starts defrosting
operation.
No hot air comes out of the indoor unit during
defrosting operation.
