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.
Recommended temperature setting

or cooling: 26
˚C – 28˚C
For heating: 20˚C – 24˚C
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.

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.
