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 50-120btu/h (15-35W) of electricity even while it is not operating.
The outdoor unit consumes 3.4-34btu/h (1-10W) to have its electric components work even while it is not operating.
During standby electricity saving mode : about 3.4btu/h (1W)
The outdoor unit consumes about 120btu/h (35W) of power at the time of compressor preheating.
