Switching on the device 

7.

  Connect the humidifier to the mains supply: The 

mains cable must be connected to a socket that 

is supplied with the mains voltage of the country 

in which the humidifier is used. The ON/OFF 

switch is located on the rear of the device. Check 

that the LED light on the front panel lights up 

when the humidifier is connected to the mains 

supply and the mains switch is pressed.

 

Switching off the device 

8.

  You can switch off the device by pressing the 

switch on the rear of the device. This switch is 

used to simultaneously disconnect all poles of the 

device's circuits from the mains.

 

 

6.  Operation 

 

The “Neonate configuration” differs graphically from 

the “Adult configuration” by the breathing circuit 

displayed on the main screen.  

Neonate configuration 

 

N – Operating screen 

 

  When the device is switched on, the operating 

screen is displayed: The humidifier is in operating 

mode and begins to heat the tubes and the water in 

the water chamber to the set control temperatures. 
When the humidifier is switched on, it automatically 

recognises the electrical configuration of the 

connected ventilation tubes and displays a 

corresponding screen: 

 

Screen display for humidifier in a configuration with
