• Indoor unit quiet operation
When the air flow is set to “ ”, the noise from the indoor unit will become quieter.
Use this when making the noise quieter.
The unit might lose capacity when the air flow rate is set to a weak level.

The air flow rate setting is not variable.

Note on HEAT operation
•
• 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.
•
• During defrosting operation, hot air does not flow out of indoor unit.

Note on air flow rate setting
• At smaller air flow rates, the cooling (heating) effect is also smaller.
Five levels of air flow rate setting from “ ” to “ ”
plus “ ” “ ” are available.
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.
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.
This air conditioner cools the room by blowing the hot air in the room outside, so if the out-
side temperature is high, performance drops.
The computer chip works to rid the room of humidity while maintaining the temperature as
much as possible. It automatically controls temperature and fan strength, so manual
adjustment of these functions is unavailable.
In AUTO operation, the system selects a temperature setting and an appropriate operation
mode (COOL or HEAT) based on the room temperature at the start of the operation.
The system automatically reselects setting at a regular interval to bring the room tempera-
ture to user-setting level.
If you do not like AUTO operation, you can manually select the operation mode and setting
you like.
