NOTE
MODE Notes on each operation mode
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.
HEAT
COOL
DRY
AUTO
FAN This mode is valid for fan only.•
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 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 fl ow out of indoor unit.•
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.
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.
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.•
The OPERATION lamp goes off.•
To change the temperature setting

Operating conditions
Recommended temperature setting
For cooling: 26°C – 28°C•
For heating: 20°C – 24°C•
Tips for saving energy
Be careful not to cool (heat) the room too much. •
Keeping the temperature setting at a moderate level helps save energy.
Cover windows with a blind or a curtain.•
Blocking sunlight and air from outdoors increases the cooling (heating) effect.
Clogged air fi lters cause ineffi cient operation and waste energy. Clean them once in about every 2 weeks. •
Notes on the operating conditions
The air conditioner always consumes a small amount of electricity even while it is not operating.•
If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker off.•
Use the air conditioner in the following conditions.•
