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 dur-
ing 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 horizon-
tally, and for heating, set the air flow downward. Also, set
the air flow so that it does not blow directly on your body.

1The power consumption while the equipment is stopped
varies with the type of outdoor unit, etc. Consult your
dealer for further details on power consumption.
•
Do not use and room heater under the indoor unit.
Heat may deform the indoor unit of suction grille.
•
Do not place things near the air outlet or air inlet.

conditioner or make it stop.
•
When the display shows “

AIR FILTER), refer to the instruction manual of the
indoor unit, and clean the air filter.
•
Use timer operation effectively.
It takes time for the room temperature to
reach the set temperature. Therefore, use
timer operation to start the air conditioner
ahead of time.
