Turn the breaker ON
• Turning ON the breaker opens the flap, then
closes it again. (This is a normal procedure.)
NOTE
 Tips for saving energy
• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps save energy.
• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the cooling (heating) effect.
• Clogged air filters cause inefficient operation and waste energy. Clean
them once in about every two weeks.
 Please note
• The air conditioner always consumes 15-35 watts of electricity even while it is not operating.
•
If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker OFF.
• Use the air conditioner in the following conditions.
• Operation outside this humidity or temperature range may cause a safety device to disable the system.

NOTE
DRY mode AUTO or COOL or HEAT or FAN mode
The air flow rate setting is not variable.
Five levels of air flow rate setting from “ ” to “ ”
plus “ ” “ ” are available.
 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.
• When the indoor temperature reaches the demanded temperature the unit stops heating.
However, the indoor fan is in operation. This is standard condition.
 Note on COOL operation
• This air conditioner cools the room by blowing the hot air in the room outside, so if the
outside temperature is high, the performance of the air conditioner drops.
 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, manually change the set temperature.
 Note on air flow rate setting
• At smaller air flow rates, the cooling (heating) effect is also smaller.
