Operating conditions
Recommended temperature setting
• For cooling: 78-82°F (26-28°C)
• For heating: 68-75°F (20-24°C)
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 2 weeks.
Notes on the operating conditions
• The air conditioner always consumes a small amount 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.
