Solution
• Correctly insert plug into outlet.
• Check other appliances to make sure outlet
is working and power is on at main.
• Thoroughly clean the ultra fine filter
(pre-filter). Refer to page 34.
• Clean the PM 1.0 Black Filter.
Refer to page 35.
• Do not use air purifier instead of a range
hood or vent. Ventilate area before using air
purifier.
• Clean the ultra fine filter (pre-filter). Refer to
page 34.
• Clean the PM 1.0 Black Filter.
Refer to page 35.
• Performance may suffer in areas where
there is a constant inflow of outdoor air.
• Move the objects or relocate the air purifier.
• Move the air purifier away from the corner
so the airflow is not restricted.
• Remove and properly reassemble the water
bucket.
• The overall air quality indicator light shows
the odor level or the PM1.0 (super ultra-fine
dust) density, whichever is worse.
• The odor sensor is designed to detect
harmful gases. Strong food odors may not
register as harmful, but the deodorizing
Black Filter will remove them.
