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 insufficient, it is rec-
ommended 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 flow out of indoor unit.

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 fan strength, so manual adjust-
ment 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 temperature at the start of the operation.
•
The system automatically reselects setting at a regular interval to bring the room temperature to user-
setting level.
•
If you do not like AUTO operation, you can manually select the operation mode and setting
you like.
