I About batteries
• When replacing the batteries, use batteries of the same type, and replace the two old
batteries together.
• When the system is not used for a long time, take the batteries out. In case the remote
controller is not used for a long time remove all batteries in order to prevent liquid leak of the
battery.
• We recommend replacing once a year, although if the remote controller display begins to
fade or if reception deteriorates, please replace with new alkali batteries. Using manganese
batteries reduces the lifespan.
• The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the
air conditioner.

The unit might lose capacity when the airflow rate is set to a low level.
NOTE
I 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.
I 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.
I 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.
I Note on airflow rate setting
