Turn the breaker ON
• Turning ON the breaker opens the flap, then
closes it again. (This is a normal procedure.)
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.
