Safety Precautions
05
To reduce the risk of electrical shock, fire or injury to person(s) read the following:
Running Environment Cautions
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%.
Unit Operation
Do not operate the unit without filters. Make sure remove plastic packaging from 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.
Never look directly at UV lamps. Direct exposure to germicidal light can cause temporary or chronic
damage to your eyesight, or even blindness.
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.

How It Works
06
Top air outlet design
UV-Photo Catalyst Device
Separate Filter Design
HEPA Filter and
Activated Carbon Filter
When the DC fan motor is running, the indoor air will be drawn through the bottom of the unit. The air will then
pass through the HEPA filter, the Activated carbon filter and the UV-C+ Photo catalytic Nano-TiO2chamber.
The purified air is then released through the outlet on the top of the unit. The Negative ion generators near the
air outlet release revitalizing negative ions into the air to refresh the air.
Six Stages Purification
1. The nylon net on the outside of the HEPA filter traps large
dust particles.
2. The high efficiency HEPA filter removes microscopic particles in the air.
3. The activated carbon filter will absorb odors and gases.
4. The UV lamp kill bacteria and viral microorganisms such as influenza,
TB and Legionnaire's Disease as well as other harmful contaminants.
5. When UV light hits the photo catalytic filter, it creates e- and h+,
which have an excellent effect in the decomposition of odors.
6. The unit also generates negative ions that freshens the room air.
Sterilization Factor
1. The UV radiation destroys the DNA structure of
bacteria and kills pathogenic microorganisms.
2. The UV ray wavelength is 254nm, and the average
intensity of UV ray irradiation is 24μW/cm2at a
position 1m below the UV lamp.

Features
The unit has a nylon net (traps large dust particles), HEPA filter (removes particles), activated carbon filter
(absorbs odors and gases), UV-C+ lamp + Photo catalytic Nano-TiO2(killing airborne pathogen) and
Negative ion generators (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 unit can be operated completely with the wave of your hand, making it suitable in medical settings to
avoid cross contamination.
3. The unit is also equipped with a safety interlock switch that will turn the power off if the bottom plate is
opened.
4. The indicator lights tell you when to replace the HEPA filter, Activated carbon filter or the UV lamp.
