If there is sticky dust on the filter, wash the filter in lukewarm, soapy water, rinse it in clean water, and dry it.

To replace the anti-mold filter, with the FRONT mark of the anti-mold filter at the front, align the two indentions near the mark with the hooks at the rear of the air intake grille, and then mount the anti-mold filter.

Attach so that the round pins at the top right and left corners of the air intake grille are inserted into the grooves at the top right and left of the indoor unit.

The air clean filter removes dust and dirt from the air, and reduces odors and smoke from tobacco. This air clean filter cannot remove harmful gases or vapors nor ventilate air in the room. You must open doors or windows frequently when you use gas or oil heating appliances. Otherwise there is a risk of suffocation in extreme cases.

The air clean filter should be sucked to remove dust in low fan speed of a vacuum cleaner once every three months. If there is heavily grime on the filter, soak the filter in lukewarm water with neutral detergent diluted 1:500 for 1 to 2 minutes then wash it. Rinse the filter in clean water, and then let it dry on the towel in room temperature. Do not bend nor give excessive force onto the air clean filter. If the filter surface is heavily blocked with dirt or damaged, replace it with new one.
