G. 3.1 - Start - up
Before using the humidier, check the following:

To start the humidier simply switch on the air conditioner, which will, in turn, automatically start and stop the humidier as required.

Ultrasonic humidier operates on the principle of ultrasonic nebulization.
The mist generated in the water tank by means of the transducer is blown into the room by the built-in fan. The humidier consists of
nebulization modules, solenoid valve for the control of the supply water, oat switch and a case that houses the fan.
Refer to HSU08RM000 manual for details.
