NOTE

!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.

!This operation dehumidifies the indoor air when

it is humid.

!In AUTO operation, the system selects a

temperature setting and an appropriate 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-seetting level.

!If you do not like AUTO operation, you can

select manually, you like the mode and setting.
