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 fi lters cause ineffi cient operation and waste energy. Clean them once in about every 2 weeks.
