Air filter
The air filter collects dust and other particles from the air and
should be cleaned at regular intervals as indicated in the table
below or when the filter indication ( ) on the display of the
remote control unit (wired type) shows that the filter needs
cleaning. If the filter gets blocked, the efficiency of the air
conditioner drops greatly.

Period 6 months
*Low Silhouette Ducted, Slim Low Static Ducted, High
Static Pressure Ducted Type (F1, M1, E1):
An air filter is not provided with this air conditioner at the time of
shipment. To get clean air and to extend the service life of the
air conditioner, an air filter must be installed in the air intake.
For installation and cleaning the air filter, consult your dealer or
service center.
NOTE
The frequency with which the filter should be cleaned depends
on the environment in which the unit is used.
<How to clean the filter>
1. Remove the air filter from the air intake grille.
2. Use a vacuum cleaner to remove light dust. If there is sticky
dust on the filter, wash the filter in lukewarm, soapy water,
rinse it in clean water, and dry it.
