Note on airflow rate setting
• At smaller airflow rates, the cooling (heating) effect is also smaller.
When the airflow is set to “ ”, the noise from the indoor unit will become quieter.
Use this when making the noise quieter.
• 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.
• A pinging sound may be heard during defrosting operation, which, however does not
mean that the air conditioner has failures.
• 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 airflow 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.
