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 recommended 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 adjustment 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.

Note on air flow rate setting

At smaller air flow rates, the cooling (heating) effect is also smaller.
