We greatly appreciate your purchase of ChungHo Nais air purification system “IGUASSU D·H·A”.IGUASSU D·H·A is designed and programmed in accordance with industrial standards. Applied 4 stages of filter system (Pre-filter, Antibiotic filter, HEPA filter and Deodorization filter) make it possible to removefine dust as small as 0.3㎛, formaldehyde and volatile organic compound which are one of the causes ofSick House Syndrome and ammonia, acetaldehyde etc. Antibiotic filter includes extract from ginkgo leaves.It refrains mold and germ from increasing. Released Cluster Ion helps to eliminate germs and virus moreeffectively. Natural humidifying method using rotating disc makes the indoor optical humidity.

Please read the instruction manual thoroughly and keep it for a future reference.

Innovative hybrid productIGUASSU D·H·A is an innovative hybrid product, which is combined with air purifier andhumidifier. Air purifier eliminates pollutant in the air and humidifier helps to keep the humidityat the ideal level.

Pure and natural humidification system Purified air filtered by filtering unit contacts wet surface of rotating disc to maintain pleasanthumidity level.

Active Cluster lon generatorActive cluster lon- ACL(Active Cluster Lon)generator releases and to the air and theyare combined with moisture to form cluster ion. It sticks to harmful substances including germ,virus etc and creates oxidative OH radical to destroy pollutant.

Superior air cleaning capacity4 stages air cleaning system equipped with Pre filter, Antibiotic filter, HEPA filter andDeodorization filter eliminates fine dust and odor substances and it inhibits microbial growthsuch as mold, germ and bacteria.

Auto operation by detecting the pollution levelIt displays the indoor air pollution level detected by particle sensor and enable user to knowpollution level easily and “Auto” mode controls the airflow speed automatically in accordancewith the air pollution level and conveniently keep pleasant air in the room.

ConvenienceThis is equipped with drawer-type water container and it is very easy to pull out.

Safety functionWhile the unit is working, when disc tank is separated from the body then purifying motorstops working to prevent the accident.

Alarm functionDisplay of Indoor air pollution level detected by particle sensor, no water indicator, alarmingwhen the humidity reaches to the set humidity level etc make easy to control.

Sleek and slim design Sleek and slim design along with convenience matches well in any place.

2. Safety precautions

Associated with the possibility for serious injury or death.Danger

● Keep the power cord pin clean from dustand water.(An electric shock offire may occur.)

● Use the designated power rating. (Inappropriate voltage may cause a fire orelectric shock as well as product failure.)

● Put the cord all the way to the end.(Unstable connection may cause fire.)

● Keep the cord out of heavy traffic areas.(This can lead overheating to outlet.)

● If the power cord is damaged or pin of power plug is loose, request follow-up service.(An electric shock and fire may occur.)

● To disconnect the unit, be sure to pull by the plug and not the cord.(Damaged power cord cancause a fire and electric shock.)

● Be careful not to step on and fall over the cord. (There is a danger of injury or an electric shock.)

● Do not touch the power plug with wet hands.(An electric shock may occur.)

Decreased deodorization.

Product is shacking over.

Bad smell comes out from air outlet.

Request follow-up service.

Replace filters with new ones and clean up pre filter.

Replace deodorization filterwith new one.

Install it on flat surface.

Replace filters with new ones andclean up pre filter.

Set the level of detection sensitivity“dull” or “standard”.

Does the lamp keep lightingblue (pollution level is low?)

Continuous smell and smoke cancause a performance degradation.

Is power outlet is bad? Use the proper power outlet.

Make sure unit is

properly plugged in.

Request follow-up

service.

Is there any dust stick ontolens of particle sensor? Clean up lens of particle sensor.

Is the sleep mode set?Does displaybutton fades out?

If sleep mode is set, displaybutton gets fading out.

Is the water tank equipped properly?

Humidity setting display isflickering.

Push the disc tank to the end.

Float-type water level sensor is floating on water?

After water tank is filled withwater, ‘No WATER’ displaylamp still is flickering?

Request follow-up service.Clean up the disctank and float-typewater level sensor.
