SURGICALLY CLEAN AIR SCA2000C Air Purifier

SAFETY PRECAUTIONS 1

WARNING

The internal UV-C bulb contains a small amount of mercury which is contained inside the bulb unless broken. Mercury and mercury compunds are known to the State of California to cause cancer and birth defects or other repoductive harm.

Be sure to follow all precautions below:
Running Environment Cautions

Use only a 120-volt outlet with grounding wire receptacle.
Do not put it in rooms with high heat, damp or wet places.
Best working condition is 10-400C.
This unit should be installed on a load bearing wall near the indoor personnel activity.
To reduce the risk of electric shock, this equipment has a grounding type plug that has a third (grounding) pin. This plug will only fit into a grounding type power outlet. If the plug does not fit into the outlet, contact qualified personnel to install the proper outlet. Do not alter the plug in any way.
This product complies with the maximum allowable concentration of ozone of 0.050 parts per million by volume (ppmv) in a 24-hour period. The Health Canada Guideline 2010 recommends that the maximum exposure limit, based on an averaging time of 8 hours, is 0.020 ppmv or less when tested in a sealed, controlled room approximately 30 m³.

Unit Operation

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 block the air intake and air outlet.

SAFETY PRECAUTIONS 2

Do not use the air purifier 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 use the unit near or on hot objects, such as range or where it may be exposed to steam.
Stop the unit and unplug the power when maintenance.
To avoid causing fire and/or shock do not attempt to disassemble the unit – only certified technicians should do this.
Do not wash or reuse the Pre-filter, HEPA-Rx filter and the Activated carbon filter.

HOW IT WORKS

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 Pre-filter, the HEPA-Rx Filter, the Activated Carbon Filter, the UV-C+ Bulb and the Photo catalytic Nano-TiO2 filter. The purified air is then released through the outlet on the top of the unit. The Revitalizing Negative Ion Generators near the air outlet releases revitalizing negative ions into the air.
The air is purified in six stages:

PRE-FILTER
ULTRAFINE HEPA-Rx PARTICULATE FILTER
ACTIVATED CARBON FILTER
UV-C+ BULB
PHOTO CATALYTIC NANO-TiO2 FILTER
REVITALIZING NEGATIVE ION CHAMBER

FEATURES AND SPECIFICATIONS

The unit has a Pre-filter, HEPA-Rx Filter, Activated Carbon Filter, UV-C+ Bulb and Super Oxidizing Photocatalytic Nano-TiO2 system and Revitalizing Negative Ion generator.

Automatic Function
The odor and particle sensor can let the unit automatically select the appropriate fan speed depending on the air quality detected.
Filters and UV Lamp Replacement Indicator Lights
The indicator lights tell you when to replace the Pre-filter, HEPA-Rx filter and the Activated carbon filter or the UV-C+ lamp.
Easy Maintenance and Low Cost
When the filters need to be replaced, simply open the front panel and pull out the filters and put the new ones in. No screws, hooks or tools are required.Model No.| ONYX (SCA2000C)
