Preparation Before Operation
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.

•
Set the room temperature appropriately.
Take care not to cool or heat the room excessively.
Adjust the temperature so that everyone in the room is comfortable.
•
Ventilate the room from time to time.
Be sure to ventilate the room after using the air conditioner for a long time.
• Do not leave the door or window open.
The air will be released, and the effect of cooling/heating
will be reduced.
• Do not allow direct sunshine to enter the room
during
the cooling operation.
Hang a curtain or blind to the window to prevent direct sunshine.
• Keep televisions, radios or stereo equipment at least
1 meter from the indoor unit or remote controller.
Otherwise, picture
disturbance or
noise may result.
• Use flow direction adjustment skillfully.
Cold air collects toward the floor and hot air collects toward
the ceiling. Therefore, for cooling, set the air flow horizontally,
and for heating, set the air flow downward. Also, set
the air flow so that it does not blow directly on your body.
