To reduce the risk of electrical shock, fire or injury to person(s) read the following:
Running Environment Cautions
Unit Operation
Use only a 220-240 volt outlet with grounding wire receptacle.
Do not use the unit in an enclosed space where oxygen, flammable, explosive or toxic vapors are given off
by oil base paint, paint thinner, some moth proofing substances. It may cause explosion or fire.
The product cannot be used in high-temperature, wet or watery places. Best working condition is 0-40
0
C
and relative humidity of < 75%.
Do not operate the unit without filters. Make sure remove plastic packaging from all the filters before operation.
Do not use the unit if the power cord or plug is damaged or the connection to the wall outlet is loose.
When removing the power plug, always hold the plug and never pull by the cord.
Do not handle plug or appliance with wet hands. Electrical shock or fire from short circuit may occur.
To avoid causing fire do not attempt to disassemble the unit - only certified technicians should do this.
Stop the unit and unplug the power when maintenance.
Do not insert fingers or foreign objects into the intake or air outlet.
Keep hair, loose clothing, fingers and all parts of body away from openings and moving parts.
Do not use the unit near or on hot objects, such as range or where it may be exposed to steam.
Do not wipe the outside, inside or any parts of the unit with flammable substances, it may cause fire!
Do not wash or reuse the HEPA filter and Activated carbon filter.
Photo catalytic is permanent, never needs replacing. When there is dust on it, clean the dust off using a
vacuum cleaner dusting brush. Do not wash it in water.
Safety Precautions

06
1. The Pre-filter traps large dust particles.
2. The two-stage Electronic cell (Electrostatic adsorption device) captures
airborne particles, as small as 0.01 microns.
3. The high efficiency HEPA filter removes microscopic particles in the air.
4. The activated carbon filter will absorb odors and gases.
5. The UV lamp kill bacteria and viral microorganisms such as influenza,
TB and Legionnaire's Disease as well as other harmful contaminants.
6. When UV light hits the photo catalytic filter, it creates e- and h+,
which have an excellent effect in the decomposition of odors.
7. The unit also generates negative ions that freshens the room air.
The air purifier functions as an air cleaner by helping to disinfect airborne microorganisms and removing
particulates from the air. The DC fan of the unit draw air through the bottom (Intake) of the unit. Then it passes
through the Pre-filter, Electronic cell, HEPA filter, Activated carbon filter and UV lamp + Photo catalytic filter. The
purified air is then released through the outlet on the top of the unit. The Negative Ion Generators near the air outlet
releases revitalizing negative ions into the air to refresh the air.
The air is cleansed in seven stages.
How it Works
1. The UV radiation destroys the DNA structure of bacteria and kills
pathogenic microorganisms.
2. The UV ray wavelength is 254 nm, and the average intensity of UV
ray irradiation is between 166.1μW/cm2 ~ 167.8μW/cm2at a position
1m below the UV lamp.
Sterilization Factor

The unit has a Pre-filter (traps large dust particles), Electronic cell (remove particles), HEPA Filter (remove
particles), Activated Carbon Filter (absorbs odors and gases), UV-C+ Lamp + Photo catalytic Nano-TiO2filter
(killing airborne pathogen) and Negative Ion generator (revitalize and refresh the air).

1. The odor and particle sensor can let the unit automatically select the appropriate fan speed depending on the
air quality detected.
2. The indicator lights tell you when to clean the electronic cell, replace the HEPA filter and the Activated carbon
filter or the UV lamp.
3. When the filters need to be replaced, simply open the front door and take off the maintenance panel, then
pull out the filters and replace a new one in. No screws, hooks or tools are required.
