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 and then connect to the power source. The main unit will be in standby mode, LED lights will be flashing slowly.

Use

Correct positioning
To achieve the best possible performance of the air purifier, the air inlets should maintain a certain distance from the walls and other obstructions when using the purifier.

Manually control fan speed
The machine is designed with 121 wind speed and it can precisely control the PM2.5 level.

Touch the top circle of the main unit and rotate clockwise to increase the fan speed (Continuously rotate clockwise until the power light remains constant indicating maximum fan speed).

Touch the top circle of the main unit and rotate counter-clockwise to reduce fan speed (Continuously rotate counter-clockwise until the power light blinks slowly in a breathing pattern for zero fan speed and enter standby mode).
Note: Above diagrams are for reference only, please prevail in kind.

The Monitoring Controller Testing Items

Your smart air purifier monitoring controller can monitor PM2.5, CO2, and TVOC concentration.
When paired with LIFAair smart air purifiers, it can automatically control the purifier main unit and maintain PM2.5 concentration in a healthy range.
It can also monitor temperature and humidity.
The monitoring controller will monitor air quality. There are six levels: good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy, and hazardous. American standards will be more stringent.

PM2.5 measurement
In the main interface press and switch to the “PM2.5” interface.
The Chinese standard requires the PM2.5 level to be below 35µg/m3.
LIFAair LA503 Smart Air Purifier - figure 15

  • American standard requires the PM2.5 level to be under 12µg/m 3.
  • It takes about 40 seconds for the value to stabilize.

CO² measurement
In the main interface press and switch to the “CO²” interface.
CO2 concentration will display on the monitoring controller, 1000ppm is good.
When the concentration is over the standard level, it is recommended to open the window for ventilation.
It takes about 40 seconds for the value to stabilize.
The average CO2 concentration in outdoor air is about 400ppm.
LIFAair LA503 Smart Air Purifier - figure 16

TVOC measurement
In the main interface press and switch to the “TVOC” interface.
According to current standards, AQI (air quality index) measurement doesn’t account for TVOC. Thus, when the monitoring controller displays“good”, it doesn’t indicate TVOC is under standard level. It takes about 40 seconds for the value to stabilize.
LIFAair LA503 Smart Air Purifier - figure 17

Note: The monitoring controller uses a semiconductor sensor to measure TVOC, it cannot replace professional instruments.
TVOC is divided into five levels:
Good: Moderate: Unhealthy: Very unhealthy: Hazardous:

Temperature measurement
In the main interface press and switch to the “TEMP” interface.
It displays the temperature at which the purifier main unit is located.
LIFAair LA503 Smart Air Purifier - figure 18

Note: To enable this function, please ensure the monitoring controller is connected with the LIFAair purifier main unit.

Humidity measurement
In the main interface press and switch to the “HUM” interface.
It displays the relative humidity at which the purifier main unit is located.
LIFAair LA503 Smart Air Purifier - figure 19

Note: To enable this function, please ensure the monitoring controller is connected with the LIFAair purifier main unit.

Short Time and Continuous Monitoring of the Monitoring Controller

Press and hold , the controller will continuously monitor air quality and will display for 5 minutes. The“Test” icon will blink on the secondary display screen.  Press to exit this mode at any time during this process.
LIFAair LA503 Smart Air Purifier - figure 20 Note: After pairing with the unit (main unit indicator light is white), the controller will regularly monitor air quality and auto-control the operation of the main  unit, regardless of what aforementioned mode is selected.
