THE IDEAL WAYS OF OPERATION

Suitable Room Temperature

Install curtain or blinds

Ventilation

Effective Usage Of Timer

Do Not Forget To Clean The Air Filter

Please Adjust Suitable Temperature

For Baby And Children

Warning

Freezing temperature
is bad for health and a
waste of electric power.

It is possible
to reduce heat
entering the
room through
windows.

Dusty air fi lter will reduce the air volume and
the cooling effi ciency. To prevent from wasting
electric energy, please clean the fi lter every
2 weeks.

Caution

Do not close the room for a long period of
time. Occasionally open the door and windows
to allow the
entrance of
fresh air.

At night, please use the “OFF or ON timer
operation mode”, together with your wake up
time in the morning. This will enable you to
enjoy a comfortable room temperature. Please
use the timer effectively.

Please pay attention to the room temperature
and air fl ow direction when operating the unit for
baby, children and old folks who have diffi culty
in movement.
