Frequently Asked Questions - FU-S51A SHARP

Why are odours not removed even after operation?

The filters may be heavily soiled. Clean or replace the Washable Active Carbon Filter and HEPA Filter. Also ensure the odour source is removed, as the purifier cannot eliminate persistent odours from construction materials or pets.

The CLEAN-SIGN light stays green even when the air is impure.

This may happen if the air was impure when the unit was first plugged in. Unplug the unit for one minute and plug it back in to reset the base impurity rate.

The CLEAN-SIGN light shows yellow or red in clean air.

The sensor openings might be dirty or clogged. Clean the dust and odour sensor openings using a vacuum cleaner.

Why does the Plasmacluster Indicator Light stay green or blue without changing?

When the unit is in Ion Control Mode (green) or Clean Mode (blue), the light will not change. It only cycles during ION SHOWER operation.

A clicking or ticking sound is heard from the unit.

Clicking is normal in Ion Control Mode, and ticking occurs during ion generation. If the sound is bothersome, move the unit further away from your seating area.

The discharged air has an unusual aroma or odour.

Check if the filters are heavily soiled and replace them if needed. Plasmacluster purifiers emit small traces of ozone, which may produce a slight odour, but these levels are well below safety limits.

How often should I clean the Washable Active Carbon Filter?

Every 2 months. Hand wash it with lukewarm water and mild kitchen detergent, rinse thoroughly, and dry in a well-ventilated area. Do not tumble dry.

When should I replace the HEPA and Active Carbon filters?

Replace filters if dust or odour persists even after cleaning. The typical lifespan is up to 5 years after opening, but heavy use (smoke, pets) may shorten it. Use replacement model FZ-S51SEF.

Can I use the air purifier in a kitchen or near gas appliances?

No. Avoid locations with lampblack, oily residue, or near gas appliances/fireplaces. The unit may malfunction or be damaged.

What should I do if the unit does not detect cigarette smoke?

Ensure the unit is placed where the sensors can detect smoke freely. Clean the dust and odour sensor openings if they are blocked or clogged.

USER MANUAL FU-S51A SHARP

FU-S51A

Please read before operating your new Air Purifier

The air purifier draws in room air from its air intake, lets the air pass through a Active Carbon Filter (deodorization filter) and a HEPA Filter (dust collection filter) inside of the unit, then discharges the air from its air outlet. The air purifier unit repeats this process by moving its internal fan.

As air passes through, a new HEPA Filter can remove 99.97% of dust particles, of as small as 0.3 microns. The Active Carbon Filter gradually absorbs odour elements as they repeatedly pass through the filter. (Odour elements are absorbed by HEPA Filter as well.)

Some odour ingredients absorbed by the filters may become separated and may be discharged through the air outlet and result in additional odour. Depending on the usage environment, especially when the product is used in a condition significantly more severe than household use, this odour may become strong in a shorter period than expected.

If the odour persists, then the filters are fully expended and it is necessary to purchase the optional replacement filter.

NOTE

• The air purifier is designed to remove air-suspended dust and odour, but not harmful gases (for example, carbon monoxide contained in cigarette smoke). If the odour sources still exist, it cannot completely remove the odour. (for example, odours from construction materials and pet odours).
• It is suggested to open the window a bit when you are smoking in order to facilitate ventilation.

FEATURES

ION SHOWER

New ION SHOWER Operation Mode releases the concentrated Plasmacluster lons, and effectively removes the pollen and mold, and also controls the activity of airborne virus, mold, and allergen.

Plasmacluster Ion Control

Your new air purifier will control the ratio of negative ions and positive ions depending on the condition of the room.

- Clean Mode

Approximately the same numbers of positive and negative ions are discharged.

• AUTO Plasmacluster Ion Mode

The unit will switch between Clean Mode and Ion Control Mode ^* automatically depending on the amount of impurities in the air detected by the odour and dust sensors.

\*Ion Control Mode

Negative ions will be released in an increased rate and controls the ion balance.

- Filters

1) Washable Active Carbon Filter Absorbs odour elements. Washable to maintain optimum deodorization performance.
