Operation
1. Display: the display indicates the room temperature in Celsius. If no function button is pressed,
the display will turn dark after 5-seconds.
2. Mist Button: press the Mist Button to choose between levels 1~5. Level 5 is the highest power
working mode. The default mist level is 5.
3. Humidity Button: press the Humidity Button and it will increase 5%RH (relative humidity). If you
want to set a target humidity, it has a range from 40%-90%RH. Continue to touch until max 90%.
Cycle through if you go past your desired RH. When the %RH reaches your target humidity, the
fogger will stop. The fan will stop after 10-seconds, along with the Anion function.
4. Timer Button: the timer can be selected in 1-hour increments, from1-12 hours. Once you
choose your setting, after 3-seconds, it will turn to timer mode. Once the duration is complete,
the machine will auto turn off. Touch the Power Button to restart.
5. Anion Button: the Anion function creates negative ions, which cause floating particulates (dust,
dander, allergens, pathogens) in the air to cling together and drop to the floor. If the disinfectant
runs low, the Anion function will auto turn off. Once the tank is refilled, the Anion function will
work again.
6. Auto/Sleep Button: touch sleep to start sleep mode, touch any button to wake up.
Disinfectant Shortage
