Care and Cleaning (continued)
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 needs to be installed behind the air intake grille.
1. Remove the air intake grille.
2. Install the air clean filter in the position
shown in the figure.
3. Remount the air intake grille.
• In general, the 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, 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.
Purchase a replacement filter at your local dealer. (model STK-FDXB)
• Wipe clean using a soft, dry cloth.
• To remove stubborn dirt, moisten a cloth in warm water no hotter than 104 °F, wring
thoroughly, and then wipe.
• The air intake grille can be removed in order to wash it with water.
Refer to "How to remove the anti-mold filter" and "How to replace the anti-mold filter" on
page 23.
When using a footstool or the like, be careful not to let it tip over.
• Clean the grille gently using a soft sponge, or the like. Then wipe away any remaining
moisture.
• Neutral detergent may be used to remove stubborn dirt. Then rinse thoroughly with
water and wipe away any remaining moisture.
Follow the steps below when the generator has
become dirty.
For safety, be sure to turn the air conditioner
off and also to disconnect the power before
cleaning.
Remove the dust on the negative ion generator.
• Use a toothbrush, etc. to dust off the end.
• Use a cotton swab, etc., to clean around the
generator inside the plastic case, taking care
not to touch the electrodes.
• During use, the negative ion generator and other metal parts may become discolored:
this is normal and not indicative of malfunctioning.
• If the dirt on and around the negative ion generator is left to build up, a puffing or
sputtering sound will eventually be heard. In this case, clean the generator immediately.
• Do not apply excessive force while performing maintenance.
