Initial Installation

Cover the ground with a layer of soft towel or any protective pad, flip the main unit upside down while rotating the bottom cover to unlock. (Make sure that DC power is turned off).
Remove the bottom cover.
Hold the top of HEPA filter with both hands and lift to remove.
Open the protective bag to find the side handle of activated carbon barrel, take out the carbon barrel (repeat the same action for the carbon barrel at the bottom).

Remove the protective bag on the carbon barrel.
Put back the HEPA filter into the carbon barrel.

Initial Installation

Put the carbon barrel and filter combination back into the main unit and gently shake it in place (Repeat step 6 and 7, and put the second layer of the carbon barrel and filter combination into the main unit).

Close bottom cover.

Lock the bottom cover (be sure to rotate the bottom cover to the lock position).

The installation is completed. Flip the main unit carefully back to the upright position.

Connect the power supply

Remove the protective strip on the DC power connector, take out the power cord and connect to the power adapter. Connect the adapter to the main unit & plug in the power. The main unit will be in standby mode, LED lights will flash slowly.

Use

Correct positioning
In order to optimize the best use from the air purifier, please ensure that air inlets should maintain a certain distance from the wall and other obstructions. 

Manual control wind speed
The machine is designed with 121 wind speed, the accurate speed control setting can reflect the PM2.5 level precisely.

Touch the top surface of the main unit, rotate clockwise to increase wind speed (Continuously rotate clockwise until the power light remains constant indicating maximum wind speed).

Touch the top surface of the main unit and rotate counter-clockwise to reduce wind speed (Continuously rotate counter-clockwise until the power light blinks slowly. You are entering standby mode at zero wind speed).
Note: The pictures in this manual are schematics and may slightly differ from final production, therefore defer to the product.

How to Pair Smart Controller with the Main Unit

Pairing: Smart controller can be connected to the main unit via Bluetooth. This machine has been paired at the factory, therefore you can directly plug to use. If you require pairing, please follow the steps below.

1. Plug in the main unit first, press and hold the on/off key on smart controller to switch on the unit. Once the light turns green on the main unit, it is switched on.

2. Slide the touch surface counterclockwise so that the green light blinks slowly. With one finger press and hold the “o” position on touch surface for more than five seconds until the green light flashes rapidly. The main unit will pair with the smart controller within 30 seconds.
   

3. Click settings on the screen , smart controller and the main unit are into self pairing process.
   
   4. After successful pairing, the main unit power/status indicator turns white, the monitor prompts ” Pairing Completed “. If pairing fails, repeat the above steps.
   

Smart Controller Tests

Your air purifier’s smart controller can accurately monitor carbon dioxide (CO2) concentration, formaldehyde concentration, PM2.5 concentration and automatically purifies the environment. The concentration of PM2.5 and formaldehyde is reduced to a healthy range. After pairing with the main unit, the smart controller can also monitor temperature and humidity. The smart controller will monitor air quality measured in six levels: good,moderate, unhealthy for sensitive groups,unhealthy, very unhealthy and hazardous.

Touch ” CO2″ for accurate reading of carbon dioxide. ≤1000ppm is in the good range. We recommend that you open windows for ventilation if your reading exceeds this number.  It takes approximately 40 seconds to stablize the room and adjust CO2 levels.
Touch ” HCHO ” for accurate reading of formaldehyde concentration. China Standard is ≤ 0.08mg/m3, United States Standard is ≤ 0.06mg/m3

The formaldehyde sensor inside the controller operates based on electrochemical principles, hence it can be affected by other non-formaldehyde gases, especially alcohol and perfume.  Formaldehyde in the room releases continuously and slowly, it does not increase suddenly in a short period of time, so if the reading rapidly increases, please remain calm and note that it could be perfume or other substances. A stable reading will follow.

Touch “PM2.5” to display realtime measurements of PM2.5. It takes about 20
seconds for a reading. China Standard 75μg / m3 ,  American standards is 35μg / m3

Touch ” TEMP ” to show temperature reading

Warning

Main unit warnings:

When main unit purifier is operated, it cannot be tilted, otherwise this screen appears on the smart controller.
Formaldehyde reading error:

Because formaldehyde sensor is not only sensitive to formaldehyde, when abnormal formaldehyde readings are detected, the screen changes to this picture.
Ventilation warning:

When you open windows, doors or leave home, the smart controller may detect abnormalities and this screen will appear. The main unit will stop working when the window is opened. After you complete ventilation, doors and windows should be closed or return home, then click the auto mode sleep mode auto mode, to restore full intelligence operation. You can also directly touch and slide the circle so that the main unit is back to work.

Maintenance
Filter replacement (Make sure that the main unit stops running, un-plug the power cord and then clean or replace the filters)

Refer to “First Installation” section, find the carbon barrel handle after opening the bottom cover, respectively, take out the two barrels of carbon filters and HEPA filters, replace the filters and then put into the main unit.
When the filter detection value in smart controller is less than 5%, you need to clean or replace the filter.
Clean the prefilter

Troubleshooting

Purifier not working?
Please check whether the power cord is connected correctly.
Please check whether the purifier is at minimum wind speed.
Please check whether the bottom cover is in the lock position.

Running noise?
Please check whether the filter is installed.
Please check whether the protective bags of the carbon barrel have been removed.

Do formaldehyde readings suddenly increase?
Because the formaldehyde sensor is an electrochemical sensor, many other gases will react, such as alcohol, perfume, humidity sudden increasing can produce
false readings, which is a normal phenomenon. If the interference cannot be eliminated for a long period, please perform Zero Settings→ Settings → Sensor calibration indoors, directly press the formaldehyde sensor zeroing → confirmation.

Does formaldehyde or carbon dioxide have inaccurate readings?
Please use the following process:
Settings → sensor calibration, according to the standard method of zeroing in outdoors for 30 minutes, use the “Testing Mode” when turn on the smart
controller, and then perform zeroing for formaldehyde and carbon dioxide sensor respectively.
